Conflicting Scientific Evidence
According to the Mayo Clinic, multiple studies have indicated that St. John's wort is just as effective as prescription tricyclic anti-depressant drugs such Tofranil and Elavil in treating either mild or moderate depression. In addition, some studies have suggested that St. John's wort may also be as effective as serotonin aids Prozac and Zoloft. Studies have not gathered evidence indicating whether St. John's wort is effective in the treatment of anxiety disorders, obsessive compulsive disorder or seasonal affective disorder. The NIH asserts that, while some studies have shown St. John's wort to be as effective as prescription medications, two studies have concluded that St. John's wort was not any better at treating depression than a placebo.
St. John's wort is significantly cheaper than prescription anti-depressants. However, medical insurances will not cover the expense at all. At Walgreens.com, a 2 ВЅ-month supply of St. John's wort is $19.99. Prescription anti-depressants medications may cost $100 or more for a month's supply, and, even with medical insurance, they will still be more than the cost of St. John's wort.
The recommended adult dose of hyperacin is 0.17-2.7 milligrams, and the recommended dose of St. John's wort extract is 900-1800 milligrams. However, doses may vary depending on what brand of St John's wort is purchased. The strength of herbal supplements may vary by manufacturer, which make proper dosing difficult. Dosages of prescription medications are always exact.

The occurrence of side effects with prescription medications is greater than with St. John's wort. Prescription anti-depressants may cause side effects like sleep problems, dry mouth, memory loss, concentration problems, weight gain, disorientation and sexual problems.
