njoy your next cup of herbal tea while toasting to better health. U.S. Department of Agriculture-funded researchers have confirmed the sciencebased 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-plateletclumping action. They found that peppermint tea also shows significant antimicrobial, 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.
The Power of Good Posture

other’s warnings against slouching were correct. Recent research proves that poor posture not only makes a bad impression, it can make us feel physically weaker. The study, published in the Journal of Experimental Social Psychology, explored the relationship of posture and pain tolerance and found that by simply adopting more dominant poses, people can feel more powerful, in control and better able to tolerate distress. More, those studied using the most dominant posture were able to comfortably tolerate more pain than others assigned a more neutral or submissive stance. People tend to curl up into a ball when in pain, but the University of Southern California researchers recommend doing the opposite—try sitting or standing up straight, lifting the chin, pushing out the chest, and generally expanding the body shape. They suggest that these small, yet empowering, changes in behavior can decrease sensitivity to pain. Adopting a powerful posture may even affect the body’s hormone levels, boosting testosterone, which is associated with increased pain tolerance, and decreasing cortisol, typically released in response to stress.
