डिप्रेशन (अवसाद) के लिए सेंट जॉन्स वॉर्ट (St. John’s Wort): साक्ष्यों की समीक्षा

Absolutely NOT. Combining St. John’s Wort with any antidepressant (SSRIs, SNRIs, MAOIs, tricyclics) can cause serotonin syndrome — a potentially fatal condition with symptoms including agitation, confusion, rapid heart rate, high blood pressure, fever, seizures, and muscle rigidity. Allow a 2-week washout period between stopping one and starting the other.

Like pharmaceutical antidepressants, St. John’s Wort requires 4–6 weeks for full effects to develop. Some people notice subtle improvements in sleep or anxiety within 2 weeks, but significant mood improvement typically occurs at the 4–6 week mark. If there’s no meaningful improvement after 6–8 weeks, it’s unlikely to be effective for you.

Yes. St. John’s Wort induces CYP3A4 enzymes that break down the hormones in birth control pills, patches, and rings, significantly reducing their effectiveness and increasing pregnancy risk. If you take hormonal contraception, do NOT use St. John’s Wort. IUDs and barrier methods are not affected.

The most studied dose is 300 mg of standardized extract (0.3% hypericin, 3–5% hyperforin) taken three times daily for a total of 900 mg per day. Start with 300 mg once or twice daily for the first 1–2 weeks to assess tolerance, then increase to the full dose. Always take with food.

Hypericin, one of St. John’s Wort’s active compounds, is a photosensitizing pigment that increases your skin’s sensitivity to UV radiation. This means you burn more easily and may develop rashes. Use SPF 30+ sunscreen daily, wear protective clothing, and avoid prolonged sun exposure or tanning beds, especially if fair-skinned.

There is some evidence that St. John’s Wort may help mild anxiety, likely through its GABAergic and serotonergic effects. However, the evidence is much stronger for depression than anxiety. For significant anxiety disorders, consult a healthcare provider for evidence-based treatments like CBT or appropriate medication.

Evidence supports that St. John’s Wort can be taken long-term if it’s effective and you’re not taking interacting medications. However, reassess with your healthcare provider every 3–6 months to evaluate whether continued use is appropriate and whether your depression requires different treatment.

Yes. St. John’s Wort can trigger mania or hypomania in people with bipolar disorder, just as pharmaceutical antidepressants can. It is contraindicated in bipolar disorder. If you have bipolar disorder or a history of manic episodes, do NOT take St. John’s Wort. This is one reason why a proper diagnosis before treatment is essential.

They work through different mechanisms: St. John’s Wort inhibits neurotransmitter reuptake (broader, weaker) while 5-HTP is a direct serotonin precursor (more targeted). St. John’s Wort has stronger clinical evidence from large trials. NEVER combine them — the risk of serotonin syndrome applies to both when used with other serotonergic substances.

Yes — stop at least 2 weeks before any scheduled surgery. St. John’s Wort can interact with anesthetic agents, prolong or alter sedation effects, and interfere with pain medications used during and after surgery. Inform your surgeon, anesthesiologist, and all healthcare providers about any herbal supplement use.

There is insufficient safety data to recommend St. John’s Wort during pregnancy or breastfeeding. Animal studies have shown some concerning effects, and active compounds can pass into breast milk. If you’re pregnant, planning pregnancy, or breastfeeding and experiencing depression, consult your healthcare provider for safer, well-studied alternatives.
