St. John's Wort

St. John's Wort (Hypericum perforatum) is indigenous to all of Europe, western Asia, and northen Africa. It has since been introduced to eastern Asia, Australia, and New Zealand; and is cultivated in Poland and Siberia. The plant has been used medicinally for over 2,000 years. The flower and leaves can both be used medicinally, as well as the oil derived from them. Two important constituents of St. John's Wort are hypericin, adhyperforin, and hyperforin. Hyperforin and adhyperforin appear to modulate the effects of serotonin, dopamine, and noradrenaline. St. John's Wort is believed to combat depression by boosting the levels of certain chemical messengers in the brain. This takes place because St. John's Wort boosts levels of serotonin in the central nervous system. Topically, St. John's Wort has demonstrate antibacterial and anti-inflammatory activities. St. John's Wort has traditionally been used for skin inflammation, wounds and burns, depression and anxiety.
