Hibiscus tea elevates the antioxidant level of one's bloodstream within an hour of consumption.
Rooibos (red) tea may reduce stress levels by suppressing adrenal gland function. Nettle tea is mineral rich but may have estrogenic side effects.
Here's the beverage comparison video I mentioned with the hibiscus punch recipe: Better Than Green Tea? Note that's erythritol pictured, not sugar (see Erythritol May Be a Sweet Antioxidant) and I also throw in a teaspoon of amla (dried Indian gooseberry powder, see Amla: Indian gooseberries vs. cancer, diabetes, and cholesterol) and my most recent addition is about a half-inch of fresh ginger root—yum! If you throw in some fresh or frozen berries too you're approaching my Pink Juice with Green Foam. The impressive manganese content of hibiscus tea may exceed recommended limits at high intakes, though, so we probably shouldn't drink more than a quart a day.

And for more flower power, check out what the saffron crocus can do against depression (Saffron vs. Prozac), PMS (Saffron for the Treatment of PMS), stress (Wake Up and Smell the Saffron), and dementia (Saffron for the Treatment of Alzheimer’s). There are also chamomile flowers (Red Tea, Honeybush, & Chamomile), though Chamomile Tea May Not Be Safe During Pregnancy, and the rose bush: Dietary Osteoarthritis Treatment.
