Triphala

Triphala, the classic Ayurvedic blend of amalaki, bibhitaki and haritaki, has its best (though still low-quality) evidence as a mouthwash for plaque and gingivitis, where it performs roughly like chlorhexidine. Its far more popular use — as a daily digestive and "detox" tonic — rests on tradition and small, poorly controlled trials.

What the science says

  • Reduces dental plaque and gingivitis as a mouthwash Moderate evidence

    A 2024 systematic review and meta-analysis in children found Triphala mouthwash comparable to chlorhexidine for plaque and gingival index reduction, without chlorhexidine's staining and taste disturbance. A broader 2023 systematic review of Ayurvedic plaque-control agents reached similar conclusions. Most included trials were small, short (2-4 weeks) and single-centre, so certainty is low.

  • Relieves constipation and improves bowel regularity Limited evidence

    Haritaki and bibhitaki contain anthraquinone-type and tannin constituents with laxative activity, and small open-label studies report improved stool frequency. There are no adequately powered, placebo-controlled trials of Triphala in functional constipation, so the widespread "gentle daily laxative" claim is essentially untested in modern terms.

  • Improves metabolic markers (weight, glucose, lipids) Limited evidence

    A few small randomized trials report reductions in body weight, fasting glucose and cholesterol with 5-10 g/day, but sample sizes are typically under 60, blinding is inconsistent, and results have not been replicated outside their region of origin.

  • Antioxidant, anti-cancer or immune-modulating effects Limited evidence

    These claims come from in-vitro and animal work — for example, immunomodulatory effects in oral precancer cell models. No human clinical outcome data support them.

Dosage & safety

Studied doseOral studies used 500 mg to 10 g/day of Triphala powder (churna) or extract, most commonly 1-3 g/day taken at night with warm water, for 4-12 weeks. Mouthwash trials used a 6% aqueous Triphala rinse, 10 mL swished twice daily. Products vary enormously in the ratio of the three fruits and in extract strength.
SafetyThe most common effects are loose stools, flatulence and abdominal cramping, especially above 3 g/day. Because of the anthraquinone content it is not appropriate for prolonged daily laxative use, and the EU has restricted hydroxyanthracene-derivative preparations in food supplements. Triphala can lower blood glucose (additive with antidiabetic drugs), and its tannins reduce absorption of iron and of several medications — separate by 2 hours. Ayurvedic products have a documented history of heavy metal (lead, mercury, arsenic) contamination; buy only third-party tested brands. Avoid in pregnancy, breastfeeding, bowel obstruction and inflammatory bowel disease.
