Does use of alternative medicine in addition to conventional therapies predict prolonged survival from cancer? Even if the alternative therapies themselves were useless, one might predict users would live longer, because they tend to have more hope, a greater will to live; nearly three times as likely to believe their cancer was curable even if it wasn’t. But death rates were actually higher in alternative medicine users. Follow them up years later, and 79 percent of the alternative medicine users had died compared to 65 percent of nonusers. Now if the alternative medicine users started out sicker, that could certainly explain that, and they did tend to be, though the difference didn’t reach statistical significance. Bottom line: the association between the use of alternative medicine and shortened survival is not necessarily cause and effect, but it’s possible some of the alternative modalities may have indeed been harmful.

Thanks to the internet, there has been a resurgence of older complementary and alternative cancer treatments, such as laetrile, which is a compound derived from amygdalin, a natural cyanide-containing substance concentrated in apricot kernels, the seeds inside the pits. It was branded as a “vitamin” to skirt regulations—vitamin B-17—but it’s not a vitamin, and the lack of laetrile’s effectiveness against cancer and the risk of side effects from cyanide poisoning led to it being banned decades ago. However, no surprise, you can still buy it on the internet, along with the apricot kernels themselves. Why not just give them a try, though? Because of cyanide intoxication.

Here’s a typical case report. Woman ate some apricot seeds she got at a health food store. So, they’ve got to be healthy, right? Twenty minutes later, she was having trouble breathing, before she slipped into a coma. They made some calculations, and it appears an eight-ounce bag of apricot kernels is enough to kill six people if consumed in one sitting. “Therefore, the continuing sale of apricot kernels as health food is troubling.”

And you never know what you’re getting. Here, this person was consuming a quarter of a teaspoon of ground apricot kernels daily, and had just switched brands the day before she ended up in the ICU. Thankfully, she survived; others are not so lucky, like this 17-year-old who was dead within a day, as severe cyanide poisoning can result in coma, convulsions and cardiovascular collapse. That’s why calling it a vitamin is so insidious. A 32-year-old woman arrives at the emergency room in a coma. Was she on anything? No, she just took some vitamin supplements. Thankfully, a relative showed up with them. Oh, B-17. They gave her a cyanide antidote and she survived. But had that relative not showed up, or been delayed in traffic or something, the case could have proved fatal.

So, “[c]ancer patients should be informed about the high risk of developing serious adverse effects due to cyanide poisoning after laetrile or amygdalin,” the natural compound in apricot seeds. Especially at risk may be those taking megadoses of vitamin C, or those not getting enough vitamin B12. See, the body has two major ways to detoxify cyanide. It can attach it to B12 to form the supplement form cyanocobalamin, which can be harmlessly peed out. Or, it can use the amino acid cysteine, which is also used to metabolize vitamin C, and so if you take too much vitamin C, levels can drop, and you can end up more vulnerable to cyanide toxicity.

But hey, conventional cancer treatments such as chemo can be toxic, too. It’s all about benefits versus risks. Yeah, amygdalin can block the growth of certain cancer cells in a petri dish, though doesn’t appear to have any anti-cancer effects against laboratory animal tumors.  But you don’t know what happens in people…until you put it to the test and do a clinical trial of amygdalin in the treatment of human cancer, which we’ll cover next.

  1. As a child I saw my father eating the inner part of the apricot seeds from the tree growing in the backyard. I thought they were almonds. I ate maybe as much as a thousand over several years.
    Then later at a university class (woody plants) which studies mostly the plants that grew on campus (UofU). (The state arboretum). On the topic of apricots I mentioned that as a child I ate a lot of them, and the inner seeds.
    (I was embarrassed by how old I was when, at a friends house we ate actuall almonds, that we had to remove some outer shell, which is much different than the one apricot seeds have. The inner seed appeared like and tasted like actual almonds. I would need to see both seeds next to each other, to see what differences in appearance there might be.)
    Another student declared that apricot seeds are poisonous. I said, “then I should be dead”. The professor asked where I got those particular apricots from, and I said the tree in the back yard, nowhere else. He reported that there is a variety of apricots (probably very uncommon) called Chinese Sweet Pit, that is missing the cyanide. That tree could be that variety.
    Have you heard of this variety?
    (Sadly that tree is no longer there.) I have never eaten them since.

    1. There are basically two varieties of apricots – sweet and bitter. The sweet kind have virtually no amygdalin. They are perfectly safe. However, the bitter kind contain significant amounts of amygdalin. Those are the ones that cause cyanide poisoning. They are dangerous. Cyanide kills cancer cells which is why the alternative health crowd believe eating apricot pits cures cancer. Unfortunately, cyanide kills all other kinds of cells too (and people), which is why it’s not a practical therapy.

      ‘Hydrogen cyanide (HCN) poisoning due to amygdalin (AMY) in apricot seeds is one of the public health issues in Turkey. The aim of this study was to investigate the AMY content of 13 different apricot seeds including bitter and sweet ones, and which are either sulfurized or roasted. The AMY content was determined by a high-performance liquid chromatography. Release of HCN was predicted and total amount of seeds which can cause poisoning was calculated. The mean AMY content of bitter seeds was 26 ± 14 mg g−1 and that of sweet seeds was 0.16 ± 0.09 mg g−1. The consumption of small amounts of bitter seeds may cause cyanide poisoning.’

      1. Californian almonds,bought in UK always are sweet whereas Spanish almonds, a few per kilo taste like bitter almonds. My wife and I add 4 bitter almonds to our breakfast ‘smoothy’ and have been doing so for years with no ill effects.when we add apricots to our breakfast we include the kernel of the fruit these taste bitter on their own. I have been told that in Tibet the kernel of the bitter almond is highly prized as food more so than the fruit surrounding it.

        1. The toxicity of (bitter) almonds will vary according to the cultivar, region of origin etc but according to this Tunisian study

          ‘the acute lethal dose of cyanide for mammals is as low as 0.5 mg CN/kg of the body weight, the acute oral lethal dose of HCN for humans is reported to be 0.5–3.5 mg/kg of body weight and the consumption of 50 bitter almonds is deadly for adults. However, for young children, 5–10 almonds are fatal [11].’
          https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3793392/

          1. According to Wikipedia

            ‘The enzyme rhodanese converts the cyanide into the much less toxic thiocyanate[10]. This process allows humans to intake small amounts of cyanide in food like apple seeds and survive small amounts of cyanide gas from fires and cigarettes. However, unlike alcohol, you cannot effectively condition your liver against cyanide. Relatively larger amounts of cyanide are still highly lethal because while the body can produce more rhodanese the process also requires large amounts of sulfur-containing substrates[11].’
            https://en.wikipedia.org/wiki/Mithridatism

    2. I like Dr. G. but he definitely appears to have a bias against alternative medicine. I’m a little more neutral on the matter, there are alternative cancer centers that have vastly superior results when compared to conventional medicine. In fact if we were to talk about deaths and injuries caused by conventional cancer treatments we could talk non-stop for decades and still not reach the tip of the iceberg. Alternative (cancer) treatments in reality only means doing something different than conventional, i.e. surgery, chemo, and radiation. How can you do worse than that? It completely ignores the source of the problem, which is likely a toxic diet / lifestyle, toxic thinking, toxic environment, weak immune system, stress, etc.. When the body is all congested and backed up with animal flesh, what do you expect, but a toxic body where cancer thrives best!

      And another major issue is the pharmaceutical business, they have billions of dollars to run smear campaign against any and all potential competition. Bottom line this entire industry is a mess. Learn to eat right (WF PBD), get plenty of fresh air and sunshine, drink lots of fluids, and learn to simplify your life. Is all that extra stress from a high paying job really worth it in the long run? Learn to garden.

      1. What makes you think that Dr Greger has a bias against alternative Medicine? He certainly isn’t establishment Medicine’s lap dog and he’s stated numerous times that he goes with the evidence. The problem is that he hasn’t found and solid evidence for alternative practices.

  2. Laetrile seems to have been pretty much proven near useless and actually dangerous some years ago. I’d love to see a review of research on properly managed ketogenic diet vs cancer. By “properly managed” I mean very moderate to low protein, frequent testing of relevant blood chemistry etc, and appropriate adjustments to diet and supplements to control lipid levels, mineral balance, etc. I am personally acquainted with someone who has been doing this for nearly 6 years to apparently very good effect for metastatic brain tumor that was surgically removed but leaving some satellite tumors behind.

    1. Geoffrey,

      Yes, Keto is interesting. There is a big variety in how it is done though.

      Some people do it like Atkins and that trick never works.

      Other people do it with very low animal protein and lots of low glycemic index vegetables making it is closer to Dr. Fuhrman’s diet. That is the version Dr. Berg promotes. 10 servings of vegetables, 5% animal proteins with intermittent fasting. Dr. Hyman and Dr. Oz call themselves “Pegan” I think and it is similar to that.

      Thomas Seyfried did the 3 days of water fasting, plus 3 weeks of 900 calories per day Keto diet for healing glioblastoma.

      Versus

      Alan Goldhamer, which was longer water fasting, and his diet after would be Whole Food Plant Based, no salt, sugar or oil.

      I would like to see a showdown between those two.

      Either way, it is interesting stuff.

      1. My brother did 48 hours of water fasting and I am looking forward to seeing if that is enough to have the immune system see the cancer. I know that 48 hours is what they say should be enough to lower the Heme Oxygenase-1 and that is what is tricking his immune system, so it will be interesting to see if anything measurable happened.

        He has to have a pre-op visit so I am hoping that they do a PSA or some test, which I can see a real measurable change.

        https://www.youtube.com/watch?v=jmXxqS0mgbM

        1. Did your brother do “dry fasting,” or water fasting? I’ve seen articles on the internet that suggest a day or two of fasting without any water will activate the immune system better than fasting for several days but with water.

  3. From what I read after seeing this article, apricot kernels aren’t the only thing that contains laetrile. So do apple, plum and pear seeds. I guess we need to be careful to remove apple seeds from apples before putting them in our smoothie. The seeds of berries, grapes, flax seeds, squash seeds, millet, sorghum and buckwheat are said to have some laetrile in them, hopefully in harmless amounts but it still makes me wonder how healthy my millet loaf recipe is. Same with macadamia nuts and cashews, spinach, bamboo sprouts alfalfa sprouts, fava bean and mung sprouts. Almonds and lima beans naturally have a lot of laetrile in them but it gives a bitter taste so most of it was cross-bread out. I wonder if I should change some of my eating habits.

    1. Californian almonds sold in UK are not bitter,Spanish almonds have a few very bitter kernels in a kilo,we prefer Spanish. We always add all seeds from fruit to our blended breakfast of fruit and raw, soaked overnight grains. We have been doing this for many years,I eat mostly raw, a Vegan many decades,76, works for me bitter seeds included. We are all different may be some are particularly sensitive to bitter seeds. My youngest daughter liked to shock people by eating raw lemons,now middle aged still has excellent teeth :-)

    2. Hi,

      My biggest advice would be not to eat seeds that taste sour or “bad”.

      All foods that you mentioned are very healthy that’s why I would not reccomend you stop eating them. The real thing is to eat right amounts of them. Go with a nutritionist to let you know the best portions for you.

      Yared, Health Support Volunteer.

      1. You really want to go with a nutritionist who is going to tell you to drink plenty of milk for calcium and make sure you get enough protein by eating lean meats?

  4. Many of our foods, such as almonds, spinach and millet have cyanide in them.
    https://insteading.com/blog/cyanide/

    You can die from too much water.

    I’ve been eating apricot and plum pits on purpose for years. I don’t eat 100 at a time. Many MD alternative doctors recommend eating a few (up to 18?) per day, as they release their cyanide at the site of the cancer, which all adults have growing in their bodies.

    I easily predicted what Dr. Greger would say about alternative medicine in this video BEFORE having seen it.

    John S

    1. Yes. Dr Greger reports what the science shows rather than what snake oil merchants and their deluded customers claim. It’s easy to predict what Greger will report if you know beforehand what the evidence shows.

      And just how do they magically generate cyanide only at the site of cancers then? That’s a very neat trick if it can be done.

      1. Snake oil salesmen,you prefer the drugs industry? The company that gave us thalidomide did nothing though they knew for years it was causing deformity in babies in some countries. One brave woman kept it out of the USA she was subjected to harassment and death threats. My wife dealt with breast cancer alternatively,the oncologist (UK, N.H.S) told her she would die if she did not do what she was told,this oncologist was not interested in the success from applying iodine and DMSO to the lump,now gone .

        1. Tony,
          Having had breast cancer I am intrigued by your wife’s approach to treatment. Are you saying that nothing was ingested but only applied topically?
          Did follow up mammograms indicate the cancer had disappeared?

          1. Hi Lida my Cantonese wife after diagnosis stopped dairy,still eats eggs. She does not have mammograms considered a cancer causing risk. A retired american oncologist thinks that the false positives of mammograms are not false at all but are a result of the body dealing with the cancer by the time an operation takes place. The lump close to the surface has completely disappeared. We followed the advice of canceractive.com website. They have just given a definitive on Alternative cancer treatment vitamin B17. We also have a soqui table with three far infra red domes and chi machine that she continues to love using,we bought this affordably on ebay

        2. Tony, iodine deficiency has been reported to contribute to breast cancer, particularly metastatic breast cancer. This is an article from a 2017 issue of the Cancer Journal.
          People used to use iodized salt, and consumption rate has gone down. Also flour, and other products, in the US are ‘brominated’. Water has added fluorine. Both bromine and fluorine inhibit absorption of iodine.
          (Won’t bore you with the details of why this is so. If you are interested, take a look at the Periodic Table of Elements.)
          Bottom line, people are probably getting a lot less iodine in diet than they used to.

          https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5327366/

        3. The problem with alternative cancer ‘cures’ is that they don’t work – like laetrile doesn’t work.

          ‘Cancer patients who initially chose alternative medicine therapies as the sole treatment for their cancers were more than twice as likely to die compared with patients who chose to undergo conventional cancer treatment’
          https://www.bmj.com/content/358/bmj.j4006
          https://academic.oup.com/jnci/article/110/1/121/4064136

          Sure – some people who choose alternative approaches survive – but far fewer of them than those who choose conventional care. As for your wife’s breast lump, i have no knowledge of the details of her case but this Norwegian study suggests that 22% of breast tumours may spontaneously regress. Applying iodine and DMSO topically therefore may well have been totally irrelevant.
          https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/773446

          1. Well, sorry to contradict you, but “alternative” methods in Mexico cured my cancer. It included B17 and other IVs, among other things. I also do NOT believe the comment that more alternative treated people die. It is unfortunate that most of the people I met in Mexico were people who where there trying the methods after conventional treatments failed them, as a last resort. So many of them do not make it, but is has NOTHING to do with the alternative care. It has to do with all the damage from the chemo and radiation that just couldn’t be reversed.

            1. Marie, I agree with you. I refused conventional treatments when I was diagnosed with breast cancer. I went to Mexico, Hope for Cancer, for alternative treatments which included Laetrel and Vitamin C IV’s along with many other natural, non-toxic treatments. I had no reactions from these treatments. The diet was mostly organic whole plant foods with occasional fish. After 3 years, my oncologist is happy with my outcome. No cancer shown on MRI or blood tests.

              There were many people there who had done conventional treatments first and as a last resort were trying alternative methods. It was sad to see their condition when they arrived. Several did not live long.

        4. Well stated, and of course true. The medical industry has some very good people that do amazing work, however there is another side that resists anything that threatens their position of authority, power and of course revenue stream.

      2. Personally, I’d like to see the science that shows that cyanide in seeds can attack cancer cells only and leave other cells healthfully in tact.

    2. John

      Yes, I can predict that he will do the statistics and studies, but that is why I come here.

      My dog, my best friend and my brother have cancer and there is so much disinformation on the internet that I needed the real deal.

      I am so grateful for each of these videos, and, yes, I bought a bag of apricot kernels and a container of B-17, but my dog did not like the kernel.

      After 4=a few months on things like turkey tail mushrooms, I added in CBD oil and he loved it at first, but he started to have more visible tumors and it seemed to be growing and Dr. Greger did a CBD Oil video and sometimes it grows cancer is what he verified. After that, I did give him one of the smallest doses of B-17 when I could see his cancer was getting worse, but he got sick on it and between the CBD oil and the B-17 he ended up refusing every supplement and stopped taking even the turkey tail mushrooms, which have science behind them. (I had been putting Turmeric and Ginger and lab-tested Triphala in capsules, and was giving him enzymes, but he stopped taking any of it.)

      I called the vet after the B-17 thinking I would put him down but ended up water fasting him and water fasting was so powerful and has turned everything around.

      Water fasting gets 10 fingers and toes up and a Clap, Clap, Clap and a happy dance.
      Medicinal Mushrooms gets a thumbs up – but it wasn’t enough
      Modified Citrus Pectin, I still buy the science unless Dr. Greger finds negative data, but it wasn’t enough either.
      The spices get thumbs up because they were something to try (as long as you don’t go over a month at a time with a dog and give anemia)
      The CBD Oil gets a yellow flashing light.
      Apricot kernels and B-17 gets 2 thumbs down.

      1. John,

        He has positive videos on a type of Aloe and on Beta Glucan and a mixed video on CBD oil and an “It’s worth a shot” on turmeric.

        I feel like he has helped so much because I didn’t trust either the doctors or the alternative medicine people all that much.

        It helps so much to know when results are mildly disappointing versus dangerous.

      2. Consider giving your dog beta glucan. There is a good video on youtube, interview with Dr. Vaclav Veticka …https://www.youtube.com/watch?v=vxdBOoLMONI he is a beta glucan researcher.. at the end they talk about animals and he gives his dog beta glucan every day. I will start giving our pup beta blucan.. she snores and I know it adversely affects her immune system. I like Better Way Health’s beta glucan. On an empty stomach if possible. Lots of prayers and hugs for your pup.

    3. I agree with you John.
      The “cyanide” in plants is a different animal than the poison. I would like to challenge these studies to find out specifically who funded them and what their agenda is. It is not unusual for debunkers to give us 95 percent of the truth but leave out the essential 5 percent.
      There is a lot of money to be made from “debunking” natural plant derived substances.

      1. This is fairly typical of the arguments used by the alternative health crowd – study findings that they don’t like must be ‘bogus’ or fudged and we should just take the unsupported claims of people promoting alternative cures’ as the gospel truth even when the evidence shows they are wrong. Oh and by the way all conventional cancer drugs are made from natural plant substances anyway.

        The alternative health industry is also big business with a focus on profits. Believing that beause the drug industries are in business to make money, must mean that the alternative health industries are all full of noble altruists whose only interests are people’s health and the truth, is to put it kindly naive.
        https://www.smithsonianmag.com/smart-news/alternative-medicine-is-a-34-billion-industry-but-only-one-third-of-the-treatments-have-been-tested-879

  5. your title should have been “Laetrile,” not “alternative …” Do you consider Sodium Dichloroacetate” and 3 BP as “alternative” cancer treatments? The cancer establishment does, but they can both cure some cancers if used properly. The Warburg-Seyfried-Pedersen-Ko metabolic theory of cancer is slowly establishing itself, but is still regarded as “alternative” by many. Be careful about your language.

    1. The wider study was on whether alternative treatments work and that grouped people who try alternative treatments versus those who don’t.

      Apricot seeds and B-17 are common alternative cancer treatments. If you look at the list on the chart in the video, they give a whole list of alternative things people try.

    2. Sodium Dichloroacetate isn’t legal to get without a prescription in the USA and people have already been convicted for selling fake products online.

      https://archives.fbi.gov/archives/phoenix/press-releases/2010/px082510.htm

      Is it really similar to salt and vinegar?

      “DCA blocks a key enzyme (pyruvate dehydrogenase kinase) in the metabolic pathway that produces usable energy from sugar.”

      Again, water fasting and a low animal product keto are what I see as alternatives to that.

  6. https://en.wikipedia.org/wiki/Cyanide_poisoning#Antidote

    After watching the video, I got curious about cyanide antidotes and found out in the Wikipedia article above that hydroxocobalamin (vitamin B12) is one of them:

    > made by bacteria, and sometimes denoted vitamin B12a, is used to bind cyanide to form the harmless cyanocobalamin form of vitamin B12.

    Could that be that people survive avocado pits/kernels regular consumption by also supplementing with B12a?

    1. Yes, hydroxocobalamin is the antidote to have on hand if you are going to try foolish remedies.

      That was my logic exactly.

      But water fasting bested every foolish remedy and I won’t ever be trying them again.

      1. The people peddling Apricot Kernels and B-17 tell pet owners things like, even if they vomit it up, force them to take more of it.

        I didn’t do that process, because toddlers and dogs die at 5 Apricot kernels.

        I gave him the small dose because there was a photo of a tumor on a dog which went away and I felt like he had started getting worse and it was the last thing to try. (It turned out that water fasting was the real last thing to try and that worked.)

        The smallest possible dose made him so uncomfortable and water fasting worked so well.

        There is no competition.

      2. Yes because there is no magic pills or shortcut to attain or regain a better health, only the body is self cleansing and self healing depending on the conditions and water only fasting at rest is putting the body in the best conditions to do it for every or most living organisms.

  7. All of this calls for wisdom…both circumspection and introspection. There are countless remedies and diets found in legitimate research publications and throughout the internet. Which one to adhere to? Very confusing. Chasing one fad after another by an infinite number of rabbit holes. Only to discover yet another Wizard of Oz lurking at its cul de sac.

    Common sense dictates to me that close observation of the longest living people in the so-called Blue Zone areas of the world may be instructive. There you discover no gyms, no HIIT exercise protocol, no supplements, no Keto nor Atkins nor any other trendy diet de jour, but simple, well…eat little, move much, love lavishly, commune often: All interwoven through centuries of a certain adopted lifestyle of mostly a plant based diet derived from their own gardens and simply not deliberating over every morsel they ingest, but rather celebrating the simplicity and joy of it all.

    Could we surfeited westerners learn something from these Blue Zone folks?

    1. Well, California is about as Western as you can get and the Loma Linda community may deliver the best results of all the Blue Zones

  8. Dr David Gorski has written an article on the ketogenic diet, the Warburg effect and grand claims of some doctors including Thomas Seyfried https://sciencebasedmedicine.org/ketogenic-diets-for-cancer-hype-versus-science/ which is worth reading.

    G Turner Howard, I agree with Lida, your comment is beautifully stated. As a family who grown a garden for 30 years, I would add that those blue zone communities probably also celebrate every morsel that makes it to harvest in the face of challenges from weather and pests and fruit-sampling toddlers.

    1. Wow, thanks Barb!

      He did heal someone who had Glioblastoma, but it wasn’t just Keto and Keto didn’t work until he dealt with Glutamate and not everybody can go into Ketosis, plus cancer can get glucose from animal products and your own muscles. Plus they pair it with water fasting and hyperbaric oxygen and other things.

      It just makes me wonder if the person got healed because of Keto or because the water fasting exposed the Cancer to the immune system.

      Mostly, people tend to do Keto like Atkins and it isn’t that form of it which worked.

    2. Some of his points were really interesting.

      In the animals Keto alone only helped 56%.

      Keto by itself wasn’t enough even in the animal models.

      Plus, it might make pet scans not come out properly.

      He chose the type of cancer most likely to work and it still didn’t work without giving something to deal with glutamine.

      Most people couldn’t stick to the restricted form of Keto. I couldn’t get my dog to do 90% coconut oil and I threw up every time I tried it.

      1. Are there any Whole Food Plant Based animal models using the same cancer?

        Did we beat 56%?

        That is the serious question because people with cancer have to choose and WFPB and Keto and anti-angiogenesis foods and Gerson and Methionine restriction and calorie restriction are the main players that I can think of right now.

  9. Dr Greger. Alternative cancer treatment encompasses hundreds of ideas, some totally without merit and directly harmful, no doubt

    We really need someone working with T Colin Campbell, not against him… See his latest book Whole and his seminal paper in 2017 advocating extensive trials for whole foods cancer trials. Of course, Ornish Prostate Cancer stabilization trials are great evidence that much has been ignored in the US medical system seeking maximum profits.

    Also, if I hear one more time that there is no evidence that any alternative treatment works… here are a few easy ones to get these loudmouths to shut up:

    Curcumin stops myeloma, British Medical Journal Case Study: Long-term stabilisation of myeloma with curcumin: https://casereports.bmj.com/content/casereports/2017/bcr-2016-218148.full.pdf

    Intl Journal of Dermatology, Royal London Hospital, Eggplant Derivative treats BCC, Solasodine glycoalkaloids: a novel topical therapy for basal cell carcinoma. A double‐blind, randomized, placebo‐controlled, parallel group, multicenter study, https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-4632.2007.03363.x

    1. Dr Greger has featured both Ornish’s work and Curcumin.

      He has put up the things which have good studies and even the long shots like the one patient with pancreatic cancer had a tumor go away with turmeric even though everybody else died.

      When studies show up, he will cover them.

        1. No, I am not a site moderator.

          My brother, best friend, sister-in-law, step-mother, building contractor, dog vet, aunt, uncles, cousin, other friends and my dog have cancer.

          My grandmother and grandfather on my father’s side died of cancer and my grandfather on my mother’s side died of cancer. My mother died of cancer when she was 53. A few cousins died of cancer when they were in their 50’s. One cousin has pancreatic cancer.

          I could keep going because I know so many people who have cancer or have died from it or who are doing well 25 years after medical model treatment and some who are doing well after alternative treatment and some who have been conned by things on the Internet.

          My cousin’s husband went to Mexico for treatment and died, but I know other people who did Gerson and lived.

          I know people who were healed by faith and really got healed and I saw people who were so kind hearted from church pass away over the past 2 years.

          I had symptoms myself and didn’t use medical model, but there are so many con artists recommending dangerous or expensive things that I value this site more than any site.

            1. i am watching more than one Pancreatic Cancer patient survive after going medical model right now.

              The ones like my mother died of things like infections, but medical model is starting to do things which protect the immune system and utilize the immune system. They are targeting the cancer cells better.

              I say it because the alternative community isn’t acknowledging that part.

              I hate that medical didn’t put enough priority on doing less invasive procedures and using nutrition, but the studies take a long time.

              Laetrile didn’t have any success at all in the study I looked at. Not one tumor shrunk. Not one symptom improved. Not one life extended.

              I look at the studies for things like CBD oil and sometimes it shrinks it and sometimes it makes it grow and the one study we have it shrunk every patients tumor for a few weeks and then the rumors grew back.

              Hype on the alternative products side.

              Lack of sensitivity on the medical model side.

              Modified Citrus Pectin might stop metastases 30% of the time, and maybe shrink 2 out of 20 people’s tumors and those 2 people hype it like crazy and some of us vslue the studies more than anything and please give us the statistics.

              1. My cousin’s husband flew to Mexico and took Laetrile and got his fillings removed and got IV Vitamin C.

                If I weren’t on this site, I wouldn’t know IV Vitamin C failed to do anything at all in several studies.

                People are spending $25,000 to $50,000 or more to fly to Mexico and get treated and finding out which things are worth it and which things aren’t is so important.

                1. Money is something most cancer patients worry about.

                  They have to choose between Gerson and whether to buy an expensive juicer or clay or do they do Budwig. There is a YouTube video of someone whose Breast cancer grew quicker on flaxseed oil and cottage cheese.

                  Each of these things have risks and people deserve to know what the risks and benefits are.

                  Dr Greger, you have helped me so much more than all of the sites hyping up Cancer cures put together and I spent 2 years at all of them and looking at the medical advances.

                  I hate that people shoot the messenger.

                  I would like more of these topics.

                  You are brave for doing them though.

  10. My mother had non-Hodgkins Lymphoma and was given only a few years to live back in the seventies, even with chemotherapy and radiation. She did what the doctors told her, did the chemo and radiation, but she supplemented it with Laetrile. Lo and behold, she outlived her expected life expectancy by about 25 years!!! Doctors were astonished! In her last 20 years she did not need any chemo or radiation or even Laetrile for that matter. She was perfectly healthy and died of a complication from the radiation she endured years earlier. So, Dr. Greger’s studies are not correct in this instance. Why were the doctors so surprised that she outlived her expiration date? The only thing she did different from the treatment plan they gave her was take the Laetrile given to her by Dr. Contreras in Mexico.

    1. Maybe, but people do survive and it is hard to differentiate because she had medical treatment.

      Right now the Cancer she had, the medical model rates are 92% live more than 1 year and 86% live 5 years with treatment.

      Would you tell someone who has it to skip the medical model and do Laetrile?

  11. Kernels schould be delivered with a source of sulphur to produce thiocyanate like in the Budwig diet (flax seeds +cottage). The presentation doesn’t mention it.

    Oxidation of Thiocyanate to Cyanide Catalyzed by Hemoglobin*
    (Received for publication, February 2, 1970)
    JIWHEY CHUNG$ AND JOHN L. WOOD
    From the Department of Biochemistry, University of Tennessee Medical Units, Memphis, Tennessee 38103

    http://www.jbc.org/content/246/3/555.full.pdf

    “SUMMARY
    Thiocyanate ion is oxidized at acid pH by hydrogen peroxide to sulfate and cyanide. The reaction is catalyzed in the
    erythrocyte by hemoglobin acting as a peroxidase (donor:
    Hz02 oxidoreductase, EC 1.11.1.7). Kinetic studies show
    thiocyanate ion fulfils criteria for a substrate for the peroxidase. “

    1. Since it is the cyanide that kills (cancer) cells, detoxifying the kernels by this means would defeat the whole purpose of eating the kernels for their supposed anti-cancer effects.

      1. Perhaps you didn’t read the whole article. It’s THE CYCLE. In acidic environment like cancer thiocyanate becames toxic but also STRONGLY ALKALINE cyanide.

        https://www.who.int/water_sanitation_health/dwq/chemicals/second_addendum_cyanide_short_term%20_4_.pdf

        “Cyanide produced in vivo is converted in part to thiocyanate
        by sulfur transferase systems. The thiocyanate-cyanide
        cycle probably accounts for some of the physiological effects of
        thiocyanate. “

  12. That is a very misleading title. The video doesn’t provide an answer to the self raised question!
    Based on the info provided in the video, the title should be more like “ Are Apricot seeds harmful?” Why raise a question that you’re going to answer “next”…whenever that is?
    Very disappointing article/video. Please reconsider what people read in the title and what info you provide in the body of the article/video

    1. Hi Nikk,

      I’m sorry to hear you were disappointed by the video. I know towards the end of it he references an article that states “[c]ancer patients should be informed about the high risk of developing serious adverse effects due to cyanide poisoning after laetrile or amygdalin,” the natural compound in apricot seeds.” Science unfortunately doesn’t always offer conclusive answers, but I think this offers a little heads up to those who may think apricots would be helpful.

      Source: https://www.ncbi.nlm.nih.gov/pubmed/25918920

      1. Wow, thanks, I found the actual study where 178 people were given Laetrile and enzymes and other things and none of them had any improvement of symptoms or tumor shrinkage or life expectancy, but some got toxicity.

        Not one.

      2. I suggest you go to canceractive.com and read Alternative cancer treatment vitamin B17 .Chris Woollams gives balanced well informed information on the subject

  13. I have a lump on my sternum which grew from a pea size to a marble size over a few weeks. I was waking up nightly with severe pain in my back, right in line with the lump on my chest..I started taking bitter almonds, 30 per day, 15 in the morning, 15 at night..The pain in my back completely stopped after a few days and after 3 weeks, the marble sized lump is pea sized again and is still shrinking.This wasn’t my first attempt either using apricot seeds. I took the seeds last year but didn’t continue them. Not because they didn’t work, they did and gave the same results as today. I was really busy last year and most days forgot to take them so the lump returned. When this lump shrinks even further, i am going to be taking 5 seeds a day for maintenance. Thousands of people take the seeds with no ill affects and many have survived cancer because of the seeds.

    “The cyanide is harmless when bound within other molecular formations. In addition, the body has its own safety mechanism in the form of the rhodanese enzyme, whose job is to “catch” any free cyanide molecules that may have escaped and render them harmless.”

    Maybe read this on the usual cover ups.

    https://thetruthaboutcancer.com/apricot-kernels-for-cancer/

    1. IMHO it’s better to read what the scientific evidence shows rather than read the half-baked claims of conspiracy nuts who make money selling alternative health products.

      Take for example that site’s statement that McCarrison found that the Hunzas ‘ate massive quantities of apricot seed kernels.’ As far as I know, McCarrison made no such statement and no source is given for this claim. However, other travellers reported that the Hunza ate substantial amounts of apricots both fresh and dried.

      All such alternative health claims seem to be based on stories rather than solid, well designed experimental evidence ………….. and on conspiracy theories for which no evidence is ever provided. But the conspiracy theories do provide snake oil marketers with a wonderful explanation for why the scientific evidence shows that their claims are dangerous bunk.

      1. My grandmother had not one but three different people push an alternative supplement on her that forms chlorine dioxide, otherwise known as bleach, when mixed with orange juice as per the directions. I am not going to name the supplement because I don’t want to expose vulnerable people to the marketing. I have very little doubt that ingesting this hastened her death from liver cancer.

        I am not surprised that alternative medicine users have higher mortality rates. Most of the alternative medicine crowd I have known distrust science, so the more evidence is for something, the safer it is, the less likely they are to believe it. My grandma was a mega vitamin/supplement advocate who switched to a new silver bullet every few months. The placebo effect from this was enough to keep her rheumatoid arthritis in check so that she was mobile until she died.

        Pain and Parkinson’s disease are the conditions most responsive to the placebo effect, because the placebo effect is caused by the release of dopamine and endorphins. The placebo response is less effective is tumor reduction, but in this study 2.7% of patients in the placebo group had a tumor response. Extrapolated out into the the general population of cancer patients using alternative treatments that would encompass thousands if not millions of people.
        https://academic.oup.com/jnci/article/95/1/19/252019

        And honestly, that is a good thing for them. IF, they are not doing something that is ultimately harming them in other ways. And IF, they don’t convince other people to forego proven medical treatment on that basis. Apricot kernals do not pass that criteria, because they have proven fatal in some cases. Another problem with the placebo effect is that it is a short lived response. So a placebo that cures cancer probably will stop working.

        There is no shame is having a placebo response. Virtually everyone has them sometimes, which is why is difficult to eliminate high responders from drug trials. Placebos are evolutionarily and personally advantageous. But let’s have our placebo effects about things with scientific evidence, or at the very least aren’t cyanide..

  14. It is well known in the literature that, Laetrile cyanide becomes activated because of the glucose component in the cancer cells. Non cancerous cells not having this glucose component remains untouched. Completely untouched what can be better than that folks. Here is one of the links below, explaining Laetrile action. Read/View Literature about Dr. Blaylock concerning Laetrile action as well. If Dr. Greger is not reading the Comments, please deliver it to him, he is a smart man with big heart, let him see for himself. I have a tremendous amount of respect for Dr. Greger, I am sure he will appreciate this comment. Thank you Folks …..

    1. You don’t cite the literature to support your statements instead you refer to the claims of someone who makes his moeny selling alternative health remedies.

      Blaylock is a notorious quack whose claims should not be trusted without substantial supporting evidence.

  15. I have personally known two very important cases where apricot kernels have played a major role in regaining health. In one case, our next door neighbor had stage 4 cancer that had metastasized all over her body and was given only several weeks to live and sent home to remain comfortable. As a desperate effort, she began eating the seeds constantly and made no other changes to her regimen. She was not plant-based. Soon, she was feeling better. Before long (not exactly sure how long), she returned to the doctor and it was miraculous — the cancer was gone. That was over 20 years ago. The woman lived. In the second case, my great aunt was diagnosed with lung cancer at the age of 93. By the time they discovered it, she was considered too old and frail to undergo chemo treatment. She, too, was sent home to remain comfortable. She was unable to do anything because she was so tired and could not breathe well. A gutsy woman, she decided to try the seeds, even though there was abundant caution from mainstream sources. She ordered the kernels online, put them in a large bowl, and grabbed a handful at every opportunity she had. She started regaining her strength and her lung capacity. She started gardening again, riding her bike again, and so on. Weeks later, when she returned to the doctor, the cancer was gone. Doctors were blown away. Why do we not hear about these cases and why instead do we hear this side of information? In my own case, and that of my family, we have frequently taken several seeds a day and all of us each take between 3,000 and 12,000 units of vitamin C a day, so there was no problem there. Everyone is fine.

    1. DeLaMora,

      Congratulations on your relatives surviving. You aren’t hearing about it on sites which use studies because there are not studies which showed a success. The study I read last night, out of 178 people zero had a successful outcome whether in symptoms or in longevity or in tumor shrinkage. People got sick, but nobody got better.

      I am not discounting your stories. People get healed from cancer getting vaccinations updated because it causes an immune system response, but it doesn’t happen often enough to have that be a treatment. People get healed after getting a virus, and researchers continue to study things like that, but it isn’t going to be a method doctors recommend unless studies show it as worth pursuing. People don’t eat for a few days, maybe out of distress of a cancer diagnosis and the immune system can sometimes just heal them.

      A certain percentage of people have spontaneous remission. Dr. McDougall said that it was a higher amount than you would think, which tumors just go away.

      I am not saying that it might not have worked for your cases. I will say that vulnerable people may go into a coma or die and that has to be part of the equation and the people selling them don’t say that part. They downplay the real risks and give all sorts of dosages and the kernels vary in dosage in the first place. It isn’t a regulated substance so that always has dangers.

      People who sell them say things like, “Don’t worry if the dog vomits it up, just shove it back in his throat” and that type of dangerous counsel is what is out there. I know it because I bought some.

      My dog is doing so well on water fasting and whole food plant based that I didn’t need to risk getting him sick.

      1. Dr. Greger would be so negligent to put up “take apricot seeds because there is a lot of anecdotal evidence” when there isn’t a study and people have died trying it.

  16. I have a question, it’s off topic so I apologise. I currently take the following supplements;
    -coenzyme q10
    -glucosamine sulphate
    -magnesium
    -multivitamins
    -omega 3
    -probiotics
    -resveratrol
    -royal jelly
    -spirulina
    -vitamin b
    -vitamin d
    -vitamin k2

    Are these supplements healthy for me, in terms of liver, kidney and other organ functions?

    Should I be taking any other supplements?

    I’m vegan, I’m not on any medication, I have no illnesses.

    1. Daniyal,

      Dr. Greger has videos on multivitamins, spirulina risk factors, probiotics risk factors, and when you say, “B” vitamins, if you are vegan, he recommends B-12, but folic acid would be one, which has warnings attached, so a “B-complex” would have warnings – best to get everything you can from food.

  17. Aloha Dr. Greger,
    my whole family ate handfuls of apricot pits back in the 70’s…so while it maybe true they have little or no affect against cancer..it’s hard not to think you’re fearmongering a bit. Go to the Physicians Desk Reference and read the disclaimers about Mead and Johnson’s “cytoxan”. While it’s important to present the evidence available regarding ALL “medicines” I would suggest that “normal chemo” is far more a killer than laetrile…perhaps because so many people are misinformed as to its side effects. How about presenting the evidence regarding the treatment most people receive… it’s SHIT full stop. Please take the corporations that are pimping peoples pain to task….give the evidence regarding “alternative” (ie hardly used treatments) for sure.. they should be exposed … just as, more importantly, the treatments most people receive need all the more scrutiny.

    1. It also seems that the Mayo Clinic either clumsily tried to replicate Linus Paulings work or intentionally set it up to fail with regard to Vit C. You would have thought that if you were trying to replicate Paulings findings the first obvious things to duplicate would be dosage and administration. They did not do this but were quick to report negative results.

  18. Just as a point of interest… back in 1977 I had the opportunity to talk to Linus Pauling. I called him on the phone and his wife answered and I asked if I could speak to him…her answer was ” he’s right here I can’t see why not”. Part of my reason for this call was that Sloan/ Kettering Cancer Research Hospital had just released their findings regarding the effectiveness of laetrile in fighting or curing cancer. Pauling told me that “their science” would have been flunked as junior high school science project”. He was shocked by their “intentionally” misleading results. This , of course, doesn’t mean that laetrile has a benefit in the treatment of cancer only that, arguably, the most prestigious cancer research center in the world, according to 2 time Nobel Laureate (in science) said that their findings were an intentional joke!

  19. It would be interesting to see an evaluation of Ketogenic diets as an addition to traditional therapy on this site. There is emerging evidence that Ketogenic diets are showing beneficial effects for patients with cancer
