Each 24-hour self-adhering HerbalPad® St. John's Wort Patch contains 1000mg of standardized hypericin. St. John's wort ("wort" is Old English for "plant") is the herbal antidepressant. Herbalists have known this for many years, but interest widened after the 1996 publication of a major study in the British Medical Journal. Researchers from Ludwig Maximillian University in Munich, Germany, and the Audie Murphy VA Medical Center in San Antonio, Texas, analyzed 23 previously published studies of St. John's wort, which included 1,757 people suffering mild to moderate depression. Among the subjects taking placebos, 22% reported significant relief of depression using standard tests. But among the subjects taking St. John's wort, the figure was 55% -- a significant difference.

St. John's wort may be helpful in treating the following: mild to moderate depression, moodiness, anxiety, minor external wounds, and bruises.
