TUESDAY, June 10 (HealthDay News) -- St. John's wort isn't effective for treating attention-deficit hyperactivity disorder (ADHD) in children, a new study finds.

Published in the June 11 issue of the Journal of the American Medical Association, the study compared St. John's wort to a placebo in children aged 6 to 17 and found the herb wasn't any more effective than the placebo.

St. John’s Wort (or Hypericum perforatum to the botanists, herbalists, and Latin lovers out there) is an herb commonly used to combat depression or serve as a ‘mood booster’. However, the herb will not work for every type of depression and is not recommended for use by everyone. In many ways, St. John’s wort presents a number of potential problems, especially for women.
