St John’s wort for depression

What is St John’s wort?

St John’s wort is the name given to a medicinal extract of St John’s wort (Hypericum perforatum), a herb that flowers around the time of St John’s Day (24 June) in the northern hemisphere. The plant was introduced into Australia in the late nineteenth century; its rapid and widespread growth in rural areas has led to it being formally declared a noxious weed in many parts of this country.
