Triphala (त्रिफला, Triphalā)
Three fruits, one powder, far more tradition than trial
Evidence grade 2 of 5, Thin. Read how the Atlas grades evidence.
The dental evidence is strongest. AlJameel and Almalki (Int J Dent Hyg, 2020) pooled 7 RCTs and found triphala mouthrinse improved gingival index (WMD -0.29) and plaque index (WMD -0.43) with efficacy equal to chlorhexidine, though the trials were small, largely Indian and heterogeneous. A 2024 pediatric review found no difference between the two rinses in children. The gastrointestinal side is much thinner. A 2018 review in Chinese Medicine concluded the literature does not clearly show an effect on the human digestive tract, and that no trials had assessed triphala in irritable bowel syndrome. The most cited constipation study is open-label and uncontrolled, and another used a formulation containing senna and psyllium.

What can go wrong
Triphala itself is generally well tolerated, and the common complaints are loose stools, cramping and flatulence, expected of a laxative. The larger cautions attach to the category. Saper and colleagues (JAMA, 2004) found 14 of 70 Ayurvedic products bought in Boston shops contained lead, mercury or arsenic, at extreme concentrations in the worst cases, and their 2008 follow-up found the same in one fifth of products bought online. Triphala is a plain herbal powder rather than a rasa shastra metallic preparation, so its intrinsic risk is lower, though it moves through that same lightly regulated supply chain and sourcing matters. Ayurvedic practice traditionally avoids haritaki in pregnancy. The high tannin content can bind iron and other minerals, and in vitro work suggests effects on cytochrome P450 enzymes, which argues for caution with narrow-therapeutic-index drugs.
Triphala is a powder of three dried fruits in equal parts: amalaki (Indian gooseberry), bibhitaki and haritaki. It is among the most widely used preparations in Ayurveda, taken at night in warm water as a gentle laxative and over long periods as a rasayana, a rejuvenative intended for the healthy rather than only the sick. Classical texts describe it as tridoshic, one of the few formulas held to suit all three constitutional types, which is part of why it became a household staple instead of a specialist prescription. The modern evidence sits oddly against that reputation. The best human data is not for digestion but for triphala as a mouthwash, where a 2020 meta-analysis of 7 RCTs found it worked comparably to chlorhexidine on plaque and gingival inflammation. For constipation, the use it is famous for, the controlled evidence is thin, and a 2018 review concluded the literature does not clearly show an effect on the human digestive tract.
Ayurveda's three-fruit powder, taken as a daily laxative and rasayana; its strongest human data is for triphala mouthwash, and the bowel evidence is largely uncontrolled.
How it is supposed to work
The laxative action is attributed to anthraquinone glycosides in haritaki together with the fruits' heavy tannin load, which increase intestinal motility and mucus secretion, an effect much milder than senna. Peterson and colleagues also point to modulation of the gut microbiota by the formula's polyphenols, chiefly gallic acid, chebulagic acid and chebulinic acid, which gut bacteria metabolize rather than absorb intact. The antioxidant activity seen in laboratory work is real chemistry not yet connected to a clinical outcome in people.
What people get wrong
Often saidTriphala detoxifies the body.
ActuallyNo trial has measured a toxin cleared by triphala. It is a mild laxative with antioxidant chemistry. The detox framing is a Western retail overlay, and the classical texts make a different claim entirely, classing it as a rasayana, a rejuvenative for the already healthy.
Often saidTriphala is clinically proven for constipation.
ActuallyThe 2018 Chinese Medicine review found the literature does not provide clear evidence of an effect on the human digestive tract. The most cited study is open-label and uncontrolled with no placebo arm, and another commonly cited constipation trial used a formula that also contained senna and psyllium, both established laxatives.
Often saidAs a plain ancient herbal powder it is free of heavy-metal concerns.
ActuallyTriphala is not a metallic rasa shastra preparation, so the intrinsic risk is low. Saper's JAMA survey nonetheless found roughly 1 in 5 Ayurvedic products from South Asian shops carried lead, mercury or arsenic, and triphala is sold through that same supply chain, which makes the manufacturer the variable that matters.
Who profits, and who pushes back
Christine Tara Peterson, Kate Denniston and Deepak Chopra
Review triphala as a bowel regulator acting through intestinal motility, mucus secretion and gut microbiota modulation, and report antioxidant, anti-inflammatory and immunomodulating effects, while stating that substantial areas still need additional investigation and clinical development.
AlBandary Hassan AlJameel and Sultan A. Almalki
Conclude that triphala mouthwash significantly improves clinical gingival inflammatory parameters in plaque-induced gingivitis with clinical efficacy equal to chlorhexidine, while noting substantial heterogeneity across the seven included trials.
Authors of the 2018 Chinese Medicine review on triphala in functional gastrointestinal disorders
State that the literature does not provide any clear evidence showing an effect of triphala on the human digestive tract, that no clinical trials have assessed triphala formulations in irritable bowel syndrome, and that rationally designed clinical trials are required.
Robert B. Saper and colleagues
Found that one in five Ayurvedic herbal products produced in South Asia and sold in Boston shops contained potentially harmful levels of lead, mercury or arsenic, and argued that testing of Ayurvedic products for toxic heavy metals should be mandatory.
Where the research comes from
Most of the published research on this comes from one place. 100% of it is from South Asia, spreading with Buddhist and trade networks into Tibet, Sri Lanka and Southeast Asia, and into global supplement retail from the late twentieth century. Findings that no unrelated group has reproduced are weaker than the study count makes them look.

How we got here
The three fruits carry a colonial-era English trade layer that still confuses labels: haritaki, bibhitaki and amalaki were traded as chebulic, beleric and emblic myrobalan, and myrobalan turns up in old pharmacy, tanning and dye-trade records because the same tannin-rich fruits served all three industries. Amalaki's binomial has drifted from Emblica officinalis to the currently accepted Phyllanthus emblica, so research papers and supplement labels use both names for one fruit. Triphala itself kept its Sanskrit name almost everywhere it travelled, calqued rather than replaced, surfacing as 'bras bu gsum in Tibetan and as thiripala in Tamil. Modern retail added a further name layer by selling it as a detox or colon-cleanse product, a description with no classical basis.
The three fruits were known individually long before anyone combined them. Amalaki appears in Vedic-era literature as a vitality fruit, and haritaki is prominent in early Buddhist medical writing, where it became the emblem of the Medicine Buddha. Triphala as a named combination is recorded in the classical Ayurvedic compendia, the Charaka Samhita and the Sushruta Samhita in their received forms, and is treated at length in Vagbhata's Ashtanga Hridaya around the seventh century CE, which sets out the daily rasayana framing that still governs how the powder is taken. Bhavaprakasha Nighantu, the sixteenth-century materia medica, repeats and extends the material. The formula travelled with Buddhist medicine into Tibet, where it is 'bras bu gsum, the three fruits, and into Sri Lanka and Southeast Asia through the networks that carried Ayurvedic and Siddha practice.

How it is understood
Triphala's cultural position is closer to a daily habit than a treatment. Ayurvedic texts group it under rasayana, the branch concerned with longevity and vitality in people who are not ill, and it is commonly taken at bedtime with warm water, honey or ghee depending on the constitution being addressed. It is also used as an eyewash and a gargle. Each of the three fruits has its own standing, and haritaki most of all, called the king of medicines and shown in the right hand of the Medicine Buddha in Tibetan and Himalayan iconography.
