St. John’s wort is a plant with yellow flowers that has been used in traditional European medicine as far back as the ancient Greeks.

It contains many chemicals that act on messengers in the brain that regulate mood. People most commonly use St. John's wort for depression and mood disorders. There is some strong scientific evidence that it is effective for mild to moderate depression. But St. John's wort is possibly unsafe when taken in large doses.
