What Cochrane and Other Systematic Reviews Say About Ayurveda
A plain list of what Cochrane and other systematic reviews concluded about Ayurvedic interventions for diabetes, arthritis, cholesterol, blood pressure, schizophrenia and more, and how strong each finding is.

How to use this page
A systematic review gathers all the trials on one question and judges them together. Cochrane reviews follow a strict published method. This page lists the reviews of Ayurvedic interventions we could read, grouped by health question. Each row names the intervention, because a review of one herb says nothing about another. Evidence labels: established, promising but limited, mixed, insufficient evidence, no good evidence of benefit.A PubMed search of titles and abstracts on 2026-10-22 for Cochrane reviews with "Ayurvedic" in the title or abstract found two Ayurveda-specific reviews (diabetes and schizophrenia) plus a herbal-medicines review for irritable bowel syndrome. We did not read the bowel review and make no claim about it. Proper evidence not found for other Cochrane Ayurveda reviews in that search.
Cochrane reviews
| Question | What the review found | Label |
|---|---|---|
| Type 2 diabetes (2011; 7 trials, 354 adults, 3 to 6 months) | Some herbal mixtures lowered HbA1c or fasting glucose compared with placebo or no extra treatment, others did not; no deaths, or kidney, blood or liver toxicity were reported; methodological problems and small samples prevented definite conclusions [1] | insufficient evidence |
| Schizophrenia (2007; 3 trials, 250 people) | Mental-state ratings were mostly equivocal; one herbal formula group had more nausea and vomiting; it was less likely than chlorpromazine to improve mental state; only a few small pioneering trials [2] | insufficient evidence |
Both reviews are old by research standards, and trials since then are not included.
Other systematic reviews
| Question | What the review found | Label |
|---|---|---|
| Rheumatoid arthritis (2005; 7 trials) | One high-quality placebo-controlled trial found no benefit; the rest were incompletely reported or compared with unproven treatments [3] | insufficient evidence |
| Osteoarthritis (2015; 19 randomized and 14 non-randomized trials, 2,952 people) | Large, apparently unbiased effects beyond placebo for one branded compound preparation; Shunti-Guduchi comparable to glucosamine; no convincing effect for Boswellia serrata, Ayurvedic massage, steam therapy or enema; no severe adverse events [4] | promising but limited |
| High cholesterol (2021; 32 studies, 1,386 people) | Authors reported moderate to high evidence that guggulu, garlic and black cumin moderately reduce cholesterol [5]. A separate US trial of guggulipid did not improve cholesterol [6] | mixed |
| High blood pressure (2025; 44 studies, 10 randomized trials in the pooled analysis) | No significant change versus placebo (about 2.6 mmHg systolic) or versus standard antihypertensives; high heterogeneity [7] | mixed |
| Immune markers (2022; 20 randomized trials, 1,661 people) | Some preparations were reported to raise natural killer and T helper cells; 9 of 20 trials had high risk of bias [8] | insufficient evidence for illness outcomes |
| Memory and attention, Bacopa (2014; 9 trials, 518 people) | Improved speed of attention on some tests; the authors said a large head-to-head trial is still needed [9] | promising but limited |
| Hemiplegia after stroke (2025; 30 studies) | Could not establish efficacy or safety; almost all studies had substantial bias [10] | insufficient evidence |
| Maharishi Amrit Kalash, a branded supplement (2024; 3 trials, 418 people) | Possible supportive effects with chemotherapy in breast cancer, difficult to verify; none recorded adverse events [11] | insufficient evidence |
| COVID-19 (2026 evidence map; 304 Ayush studies) | Studies vary too widely to be definitive; about half of randomized trials had low-to-moderate bias risk [12] | insufficient evidence |
| Parkinson disease, Mucuna pruriens (2025; 5 trials, 108 people) | Improved motor symptoms in small trials; three of five were low quality [13] | promising but limited |
What to keep in mind
Reviews cannot be better than their trials. Several reviewers say so directly: methodological deficiencies, high heterogeneity, or substantial bias limited what could be concluded. [1][7][10] Some reviews were produced by Ayurveda research bodies and some by Western groups, and authors with ties to Ayurveda teaching disclosed them. [11]A positive result in one review is not a recommendation to use a product. Products differ in composition and quality, and heavy-metal contamination has been found in some Ayurvedic products. [14] Tell your clinician before starting anything, especially if you take prescribed medicines or are pregnant.

A broader summary is Does Ayurveda Work?, and the reasons many reviews end inconclusively are on Quality of Ayurvedic Clinical Trials.Frequently asked questions
Has Cochrane reviewed Ayurveda?
Yes, for type 2 diabetes and schizophrenia. Both reviews found the evidence too limited to recommend routine use. [1][2]
Which Ayurvedic treatments have the best review evidence?
In the reviews we read, the strongest signals were for some osteoarthritis preparations and for a standardized Bacopa extract on attention, and both are labeled promising but limited. [4][9]
Do reviews show Ayurveda lowers blood pressure?
A 2025 review found no significant reduction compared with placebo or with standard medicines, with very inconsistent results. [7]
Are the reviews independent?
Mixed. Some authors work in Ayurveda institutions and declared it. Read the conflict statements. [11]
Why are so many conclusions "insufficient evidence"?
Because trials are often small, biased or poorly reported. [1][10]
