Three fruits, one synergistic matrix
Triphala — Sanskrit for 'three fruits' — combines Amla (Phyllanthus emblica), Haritaki (Terminalia chebula), and Bibhitaki (Terminalia bellirica) in equal parts. Each fruit contributes a distinct phytochemical profile that the others do not replicate. Amla delivers the antioxidant payload: Emblicanins, gallic acid, ellagic acid, heat-stable Vitamin C. Haritaki — called the King of Medicine in Tibetan medicine — acts primarily on the colon through chebulic acid and tannins that promote motility and inhibit pathogenic bacteria including H. pylori. Bibhitaki's ellagitannins provide anti-inflammatory activity and documented lipid-lowering effects in clinical models.
What the clinical evidence confirms
A 2017 randomised double-blind trial in the Journal of Alternative and Complementary Medicine found 5g daily Triphala powder significantly improved bowel regularity, stool consistency, and bloating scores over eight weeks. A 2019 RCT published in BMC Complementary Medicine found Triphala extract produced statistically significant reductions in body weight and waist circumference in overweight adults over twelve weeks. Most striking: a 2020 study at MD Anderson Cancer Center identified chebulinic acid — a Triphala compound — as a selective inhibitor of cancer stem cell self-renewal. Clinical translation remains years away, but the signal reached one of the world's leading cancer research institutions.
How and when to take it
Classical Ayurvedic texts prescribe Triphala at bedtime in warm water — a protocol that matches the clinical trial designs showing the strongest digestive outcomes. The traditional dose is 5g of powder; capsule formats at 1–2g are more convenient but may be less bioavailable through reduced mucosal contact. Triphala should be taken on an empty stomach. Its taste — bitter, astringent, and slightly sour — is an acquired one, and the powder in warm water is the most direct encounter with it. For those beginning Ayurvedic practice, Triphala taken nightly is the single most broadly applicable starting point.
