What the Science Says about St. John’s Wort
- There is some scientific evidence that St. John’s wort is useful for treating mild to moderate depression. However, two large studies, one sponsored by NCCAM, showed that the herb was no more effective than placebo in treating major depression of moderate severity.
- NCCAM is studying the use of St. John’s wort in a wider spectrum of mood disorders, including minor depression.
- A 2009 systematic review of 29 international studies suggested that St. John’s wort may be better than a placebo (an inactive substance that appears identical to the study substance) and as effective as standard prescription antidepressants for major depression of mild to moderate severity. St. John’s wort also appeared to have fewer side effects than standard antidepressants. The studies conducted in German-speaking countries—where St. John’s wort has a long history of use by medical professionals—reported more positive results than those done in other countries, including the United States.
- Two studies, both sponsored by NCCAM and the National Institute of Mental Health, did not have positive results. Neither St. John’s wort nor a standard antidepressant medication decreased symptoms of minor depression better than a placebo in a 2011 study. The herb was no more effective than placebo in treating major depression of moderate severity in a large 2002 study.
- Preliminary studies suggest that St. John’s wort may prevent nerve cells in the brain from reabsorbing certain chemical messengers, including dopamine and serotonin. Scientists have found that these naturally occurring chemicals are involved in regulating mood, but they are unsure exactly how they work.
