"There is some scientific evidence that St. John's wort is useful for treating mild to moderate depression," according to the National Institutes of Health (NIH).

Just as important as food, water and exercise for the health of your body is sleep. In fact, without sleep, animals in the laboratory die in a matter of weeks.

In humans, lack of sleep works havoc on biological systems. It not only causes the relatively minor symptoms of drowsiness, irritability and concentration difficulty, but it appears to also cause hormonal changes that result in increased appetite, weight gain, obesity and greater risk of diabetes, high blood pressure and heart disease.

Have you been to a practitioner besides your family physician? Whether chiropractic care, acupuncture, yoga or homeopathy, Complementary and Alternative Medicine (CAM) has become increasingly common in the United States, and 72% of adults use some form of CAM therapies according to the US National Centers for Disease Control and US National Center for Health Statistics.
