Triphala in classical Ayurveda

What it is

Triphala is Sanskrit for three (tri) fruits (phala), and the name is the recipe. Three dried fruits, generally in equal proportions (Peterson et al., 2017):

| Fruit | Sanskrit name | Latin binomial | |---|---|---| | Indian gooseberry | Amalaki | Emblica officinalis Gaertn. | | Beleric myrobalan | Bibhitaki | Terminalia bellirica (Gaertn.) Roxb. | | Chebulic myrobalan | Haritaki | Terminalia chebula Retz. |

Chemically, the blend is tannin- and polyphenol-rich (chebulagic and chebulinic acids, gallic and ellagic acids among them) (IJPPP review, 2025).

Grind them together and you have triphala churna — churna just means powder. But triphala is the formula, not the powder. The same three fruits also go into tablets, decoctions, medicated ghees and oils. This article is about the formula itself. The powder gets its own article because the clinical trials mostly tested the powder, and we want to keep the evidence attached to the thing that was actually studied.

Classical properties

• Taste (rasa): sweet (Madhura), sour (Amla), pungent (Katu), bitter (Tikta), astringent (Kashaya)
• Doshas: traditionally described as balancing for all three

Classical roots

Triphala appears in the Charaka Samhita and the Sushruta Samhita, the two foundational texts of Ayurveda, which places its documented use at over a thousand years (Peterson et al., 2017). Charaka describes Triphala Rasayana, the formula taken with honey and ghee, in the kind of language classical texts use for their most prized preparations: daily use "has the potential to make a person live for one hundred years devoid of old age and diseases." Sushruta indicates the formula for ulcers and wounds.

Read those as historical testimony, not data. A thousand years of use tells you something survived. It does not tell you it works. The next section is the part we actually trust.

What research has looked at

Oral health: the strongest human evidence

This surprised us when we first read it. Triphala mouthwash has been tested against chlorhexidine — the standard antiseptic mouthwash — in several small randomized trials, with improvements in both groups.

• In a 60-day randomized trial (n=90 adults with chronic gingivitis), triphala mouthwash, chlorhexidine and placebo were compared on plaque, gingival inflammation and microbial counts. Triphala and chlorhexidine both beat placebo (Pradeep et al., 2016).
• A crossover, double-blind randomized trial in 120 schoolchildren found reductions in plaque and gingival scores in both the triphala and chlorhexidine groups (Chainani et al., 2014).
• A randomized trial in 60 children found improvements with both rinses; chlorhexidine edged ahead on one plaque measure (Bhattacharjee et al., 2015).

Honest framing: these are small trials, mostly short, mostly in children and young adults in India. These are preliminary findings, not a treatment for gum disease. Never use it in place of, or alongside, prescribed medicine without your doctor. But it is real human randomized evidence, which is more than most traditional formulas can show.

Digestion and bowel regularity

A human clinical study of triphala in patients with gastrointestinal complaints reported reduced constipation, mucous, abdominal pain, hyperacidity and flatulence, with improved stool frequency, yield and consistency (Mukherjee et al., 2006, via Peterson et al., 2017). That is an older, small clinical study: suggestive, not decisive.

The stronger constipation evidence is a randomized trial of the powder form, which eased constipation in adults. That trial tested triphala churna specifically, so the full breakdown lives in the triphala churna article rather than being repeated here.

Blood sugar

A clinical study in non-insulin-dependent diabetes patients found triphala powder taken for 45 days significantly lowered both fasting and post-meal blood glucose (Rajan & Antony, 2008, via Peterson et al., 2017). Small, preliminary, and in the nearly two decades since it has not been followed by a large trial. A signal, not a treatment. Anyone on diabetes medication should know that combining a glucose-lowering herb with glucose-lowering drugs is exactly the kind of thing to run past a doctor first.

Weight

A 12-week double-blind randomized placebo-controlled trial (n=62) of Itrifal Saghir (the Unani name for triphala) reported a mean difference of 4.82 kg favoring the triphala group over placebo (Kamali et al., 2012). A 2025 systematic review of 15 controlled trials found a smaller average difference (−2.4 kg) in the five oral-triphala studies it could pool, with high variability between studies (Salehi et al., 2025). Preliminary. The marketing version of this finding goes far beyond the trials, and we would not buy the marketing version.

What the evidence does not yet show

For eyes: triphala pre-treatment reduced cataract formation in mice with chemically induced cataracts — 20% developed cataracts versus 100% of controls — but that is a mouse study (Peterson et al., 2017). No human eye trial exists. The traditional eye wash is tradition, not evidence.

Beyond digestion, the reviews catalogue antioxidant, anti-inflammatory and immunomodulating effects relevant to immunity, inflammation, the microbiome and cancer, but nearly all of it is laboratory and animal work, and the reviewers say so explicitly (Peterson et al., 2017). "Detox" is not a measurable clinical endpoint and has never been tested as one. These remain not shown.

Triphala is three dried fruits — amla, bibhitaki, haritaki — blended in equal parts. Small randomized trials of its mouthwash against chlorhexidine for plaque and gingivitis are preliminary; digestion and weight evidence is thinner. For the powder form specifically, see triphala churna.

Why three fruits?

Ayurvedic pharmacology (dravyaguna) reads a substance through taste, potency and post-digestive effect. Triphala's taste profile is unusual: it carries five of the six tastes — sweet, sour, pungent, bitter and astringent. The only taste missing is salty (Peterson et al., 2017). That breadth is part of the classical reasoning for the blend: no single fruit covers that range.

The formula is classed as a tridoshic rasayana — considered balancing for all three doshas and usable across ages and constitutions (Peterson et al., 2017). Rasayana means rejuvenative. That is a traditional classification, not a clinical finding. We are describing the framework here, not endorsing it as proven.

Classical texts assign the formula a dose-dependent character: mild laxative at normal doses, bowel tonic at low doses, purgative at high doses — alongside carminative, expectorant and antispasmodic actions (Peterson et al., 2017). Traditional claims, recorded faithfully. The evidence section below is where we check them.

Traditional uses

In Ayurvedic literature triphala is a pillar of digestive care and a general rejuvenative: for constipation and sluggish bowels, appetite and hyperacidity, and as a daily tonic (Peterson et al., 2017). Beyond the gut, traditional indications include the eyes — triphala is classed as chakshushya, beneficial to vision, and a strained triphala decoction is the traditional eye wash (narrative review of triphala in ophthalmology, Annals of Ayurvedic Medicine) — and the mouth, where it has long been used for oral hygiene (Peterson et al., 2017).

Every one of those is a traditional indication. Long history, genuinely long. The question is always what the trials say, and for triphala the trials are more interesting than you might expect.

Forms it comes in

Triphala is a formula, so it travels in several vehicles. The powder (churna) is the most studied. Beyond it:

• Tablets / vati — the same powder, compressed. Convenient; not what the trials tested.
• Kwatha (decoction) — the powder simmered in water and strained. This is the form used in the mouthwash trials and the traditional eye wash.
• Triphala guggulu — triphala combined with guggul resin (article).
• Triphaladi thailam — a medicated oil built on the formula (article).
• Mahatriphala ghrita — the formula in a medicated ghee base (article).

Trial results belong to the form that was trialed. The mouthwash findings do not transfer to the tablet, and the powder findings do not transfer to the oil.

Safety notes

• The trials that exist ran weeks, not years, and they were small. Nobody has run the long-term safety study, and we are not going to paper over that.
• During pregnancy: no human safety data exist. Classical Ayurvedic teaching lists pregnancy (garbhini) among the contraindications for haritaki, one of the three fruits, per the Charaka Samhita (IJAPR review, 2013). In the absence of data, the conservative course is to avoid triphala during pregnancy unless a qualified practitioner advises otherwise.
• Loose stools: as a mild laxative at normal doses, the traditional guidance is to skip it during acute diarrhea. One honest wrinkle: animal work on triphala preparations (one study used Triphala Mashi, a calcined form) actually found they prevented diarrhea (Biradar et al., 2007, via Peterson et al., 2017). The human picture is unresolved, so the cautious traditional advice stands until a trial settles it.
• Drug interactions: laboratory work suggests triphala can affect drug-metabolizing cytochrome P450 enzymes in vitro (Ponnusankar et al., 2011). That is a test-tube finding, not a documented human interaction. It is still reason enough to tell your doctor or pharmacist you are taking it, especially alongside blood thinners or diabetes medication.
• As with any laxative-acting preparation, prolonged daily use without guidance is inadvisable, and dose matters: classical texts themselves describe a purgative effect at high doses (Peterson et al., 2017).

FAQs

What are the three fruits in triphala?

Amalaki (Emblica officinalis), bibhitaki (Terminalia bellirica) and haritaki (Terminalia chebula) — dried fruit, generally in equal proportions (Peterson et al., 2017). Nothing else goes in.

Is triphala the same as triphala churna?

Triphala is the formula; triphala churna is the powder form of it. Most clinical trials tested the powder, which is why the churna has its own article (triphala churna). This article covers the formula — its composition, traditional uses, and the evidence across all its forms.

Does triphala really work as a mouthwash?

Better than you would expect. Several small randomized trials compared triphala mouthwash against chlorhexidine for plaque and gingivitis, with improvements in both groups — including a 60-day trial in 90 adults with chronic gingivitis (Pradeep et al., 2016) and a crossover trial in 120 schoolchildren (Chainani et al., 2014). Small trials, short durations. Promising, not definitive.

Can triphala help with constipation?

The human evidence is modest but real: a clinical study reported improved bowel regularity and less abdominal pain and flatulence (Mukherjee et al., 2006, via Peterson et al., 2017), and a randomized trial of the powder eased constipation in adults. Full details are in the triphala churna article.

Is triphala safe during pregnancy?

There are no human safety trials in pregnancy, so nobody can call it safe. Classical Ayurvedic teaching contraindicates haritaki — one of the three fruits — in pregnancy (IJAPR review, 2013). Avoid it during pregnancy unless a qualified practitioner who knows your situation advises otherwise.

Does triphala "detox" the body?

"Detox" is not a measurable clinical endpoint and no trial has tested it. Triphala shows antioxidant activity in lab studies, which is not the same as detoxifying the body (Peterson et al., 2017). If a seller cannot name the endpoint their product moves, there is no endpoint.

Peterson, Denniston, and Chopra's 2017 review, "Therapeutic Uses of Triphala in Ayurvedic Medicine" (Journal of Alternative and Complementary Medicine 23(8):607–614), is the backbone of this article: the three-fruit composition in equal proportions, the five-taste profile, the tridoshic rasayana classification, the classical roots in Charaka and Sushruta, the dose-dependent traditional actions, and the catalogue of preclinical findings all run through it (full text). The mouthwash evidence comes from Pradeep et al.'s 2016 randomized trial in 90 adults with chronic gingivitis (PubMed 27442086), Chainani et al.'s 2014 crossover double-blind trial in 120 schoolchildren (doi:10.3290/j.ohpd.a32674), and Bhattacharjee et al.'s 2015 trial in 60 children (doi:10.1111/jicd.12094).
