  • What's St. John's Wort Extract

St. John’s wort (Hypericum perforatum) is one of the most commonly used herbs in the United States. It is a shrubby perennial plant with bright yellow flowers. St. John's wort was named because the flowers were said to bloom for the first time around June 24, the birthday of St. John the Baptist. The word "wort" means "plant" in Old English.


There is debate about the active ingredient in St. John's wort. St. John's wort extracts are often standardized to hypericin, which led to the widespread belief that hypericin is the sole active compound. Another constituent called hyperforin has also been found to have antidepressant effects. A growing number of experts consider hyperforin to be the primary antidepressant compound.
