Other Uses & Effectiveness:
Likely Effective for
Depression. Taking St. John’s wort extracts by mouth improves depressive mood and decreases nervousness and tiredness related to depression. Certain St. John’s wort products might work as well as some prescription drugs. But not all St. John’s wort products available on the market will be the same quality as those used in these studies. So they may not work as well. Also, St. John’s wort might not be as effective for more severe cases of depression.
Possibly Effective for
Symptoms of menopause. Most research shows that taking St. John’s wort by mouth can help reduce hot flashes and other symptoms of menopause. Some evidence shows that specific combinations of St. John’s wort plus black cohosh are also beneficial. But not all St. John’s wort combination products seem work.
Emotional distressed caused by extreme focus on a physical symptom (somatic symptom disorder). Treatment with a specific St. John’s wort product daily for 6 weeks seems to reduce symptoms of this condition.
