Enjoy your next cup of herbal tea while toasting to better health. U.S. Department of Agriculture-funded researchers have confirmed the science-based health benefits of three of Americans’ favorite herbal teas.

Chamomile tea has long been said to soothe a troubled belly and restless mind. After reviewing scientific literature on the herb’s beneficial bioactivity, the study team published an article in Agricultural Research describing test-tube evidence that the beverage also offers moderate antimicrobial and significant anti-platelet-clumping action. They found that peppermint tea also shows significant antimicrobial, plus antiviral, antioxidant and antitumor actions, and even some antiallergenic potential. After reviewing human clinical trials, the researchers further reported that drinking hibiscus tea lowered blood pressure in a group of pre-hypertensive and mildly hypertensive adults.
