How Ayurvedic products are regulated, and where they are not

The regulatory status of traditional medicines varies enormously between countries, and understanding the framework where you live is the single most useful thing you can do about product quality.

India

Traditional medicine systems including Ayurveda are formally recognised, with a dedicated government ministry and a regulatory framework covering manufacturing licensing, pharmacopoeial standards and quality control requirements including limits for heavy metals and microbial contamination.

Practitioners are trained through recognised degree programmes and registered with statutory councils.

The framework exists. Enforcement across a very large, fragmented industry with many small manufacturers is a recognised challenge, and quality varies considerably between manufacturers.

The European Union and United Kingdom

Traditional herbal medicinal products can be registered under a scheme permitting products with sufficient evidence of long traditional use, provided they meet manufacturing quality standards and are for minor self-limiting conditions.

Registration under this route requires demonstration of quality and safety, and evidence of traditional use rather than clinical efficacy. Registered products carry a specific identifying mark.

Products outside the scheme may be sold as food supplements, which face far lighter requirements. Many Ayurvedic products fall into this category.

United States

Most such products are regulated as dietary supplements under legislation that does not require pre-market approval of safety or efficacy.

Manufacturers are responsible for ensuring their products are safe and labelled accurately, and regulatory action is generally taken after problems emerge rather than before products reach the market.

Good manufacturing practice requirements exist and inspections have repeatedly found violations. Products may make structure and function claims but not disease treatment claims, and enforcement of that boundary is inconsistent.

Australia and Canada

Both operate listing or licensing systems for complementary and natural health products, with requirements around manufacturing quality and permitted claims. The systems are generally more demanding than the US supplement framework and less demanding than full medicine approval.

What this means practically

The same herbal preparation can be a registered medicinal product with defined content in one country and an unregulated supplement of unknown composition in another.

Products bought online cross these boundaries invisibly. A product shipped internationally may not comply with the standards of the destination country and may not be examined at all.

The recurring quality problems

Independent testing of herbal products across markets has repeatedly documented several categories of problem.

Heavy metal contamination, covered in detail elsewhere on this site, found in a meaningful proportion of Ayurvedic products in multiple independent studies.

Adulteration with pharmaceuticals. Undeclared prescription drugs found in herbal products marketed for weight loss, sexual function, pain, diabetes and other conditions. This is documented across regulatory jurisdictions and it is a serious safety issue, since consumers take unknown doses of drugs with real interactions.

Species substitution. Testing using DNA methods has found products containing plant material other than what is on the label, sometimes entirely.

Content variability. Products containing markedly different amounts of the stated constituent than labelled, in both directions.

Microbial contamination, particularly in products from poorly controlled manufacturing.

How to reduce your risk

Prefer products with third-party testing from an independent certification programme, with results available. This is a meaningful signal and it is not universal.

Prefer registered medicinal products where the scheme exists in your country, since they have met manufacturing standards.

Check the botanical name on the label. Common names are ambiguous and a product without a botanical name is a product whose contents you cannot verify.

Check the plant part and the extract specification. Root, leaf, seed and bark differ substantially in constituents and safety.

Be cautious with multi-ingredient formulations where individual quantities are not stated.

Avoid products making dramatic claims, which are the products most likely to be adulterated to make the claim appear true.

Avoid products containing metals or minerals unless prescribed and monitored.

Report adverse effects to your national regulator. Post-market surveillance depends on reports, and under-reporting is a major limitation in this area.

Telling your doctor

Surveys consistently find that a large proportion of people using complementary products do not tell their doctors, frequently because they expect disapproval.

That non-disclosure is a genuine safety problem. Interactions between herbal products and prescribed medication are real, some are serious, and a doctor who does not know what you are taking cannot account for it.

Bring the packet. The ingredient list matters more than the name.

Tell your doctor and pharmacist about every supplement you take. Report suspected adverse reactions to your national medicines regulator.
