St. John’s Wort (Hypericum perforatum) has a long history as a medicinal herb in Europe. The ancient Greeks and Romans noted that the herbal could used for such issues as gastrointestinal distress,, depression or melancholy, superficial wounds, and menstrual cramping. The herbal has gotten its common name due to the striking yellow flowers which often blooms on the birthday of John the Baptist in the Bible. In the middle-ages the flowers were hung above doorways to ward off evil spirits. While native to Europe, it is today found in arid areas of many temperate climates around the world.
Particularly the flowers of St. John’s Wort contains active substances, such as hypericin, hyperforin, and other flavonoid compounds. Studies indicate hypericin acts as an antiviral, antibiotic, antioxidant, and non-specific kinase inhibitor. The herbal has long been known for an antidepressant effect and today this is believed to be due to the inhibition of reuptake of certain neurotransmitters. It is not clear whether hypericin or hyperforin are more important for the antidepressant and anxiolytic properties in the extracts.
In certain trials St. John’s Wort has been found to be superior to placebo in patients with depression and sometimes as effective as standard antidepressants, but often fewer side effects than the medications.
