Description: Uses: St. John's wort has been primarily studied for its potential antidepressant and antiviral effects. There is information to show that St. John's wort is more effective than placebo, but evidence is still lacking regarding its efficacy compared to the standard antidepressants, partially due to ineffective dosing. In addition, at least 3 studies have shown that commercially available St. John's wort products vary considerably in content and may be standardized to the wrong component (hypericin instead of hyperforin). St. John's wort is still in the early stages of clinical trials investigating its effects against certain viruses, including HIV.
Dosing: Traditional use of St. John's wort herb indicated 2 to 4 g/day doses. However, most clinical studies have been conducted on extracts, with hypericin content of 0.3% the earliest form of standardization. With the discovery of hyperforin's bioactivity, a content of 3% to 5% hyperforin has been used as a new standard. Some of the many products include LI 160(Lichtwer, 0.3% hypericin), Kira(Lichtwer, 300 mcg hypericin in 125 to 225 mg extract tablets), Hyperiforce (Bioforce, 0.33 mg hypericin in 60 mg extract/tablet), Ze 117, WS 5573 (300 mg extract, 0.5% hyperforin), WS 5572 (300 mg, 5% hyperforin), STEI 300(Steiner, 0.2% to 0.3% hypericin and 2% to 3% hyperforin), Psychotonin, Esbericum, Neuroplant, Sedariston, and Hyperforat. Doses of the extracts have ranged from 500 to 1800 mg/day.
