    St. John’s wort

    St. John’s wort (Hypericum perforatum) is a flowering weed that has been used for centuries for mental health conditions and is widely prescribed for depression in Europe. There are also claims that this herbal stimulant is effective for smoking cessation and treating anxiety, sleep disorders, irritable bowel syndrome, hot flashes, and premenstrual syndrome. Modern day studies, however, have yielded mixed results for its efficacy.

    What is proven is that St. John’s wort weakens the effectiveness of many prescription medications. The list includes antidepressants, birth control pills,
cyclosporine, digoxin, warfarin, oxycodone, and some HIV and cancer drugs.

    Symptoms associated with the use of St. John’s wort include agitation, diarrhea, rapid heartbeat, high blood pressure, hallucinations, sexual dysfunction, fatigue, dizziness, confusion, and a rise in body temperature. It has also been linked to a worsening of psychotic symptoms in people with bipolar disorder or schizophrenia.
