Manufacturers -- Quality and Licensing Guide

अयुृ्वेद ࣷषधि निर्माता -- Quality in manufacture determines the quality of the medicine

Classical Ayurvedic texts document that the preparation method determines the therapeutic outcome -- a principle that applies equally to modern manufacturing. This page documents the major licensed Ayurvedic manufacturers in India, quality standards to look for, and how to verify manufacturer credentials.

How to verify a manufacturer

All legitimate Ayurvedic manufacturers in India must be licensed by the state AYUSH department and comply with Schedule T GMP (Good Manufacturing Practice) under the Drugs and Cosmetics Act. Verification: ask for the manufacturer's Drug License Number (issued by the state AYUSH licensing authority) and their GMP certificate. Both should be current (renewed periodically). For export-quality products, WHO-GMP certification is the additional quality marker.

Quality standards to look for

Mandatory

Schedule T GMP compliance

All legally sold Ayurvedic medicines in India must be manufactured under Schedule T GMP conditions. This covers: facility hygiene, equipment standards, raw material testing, in-process quality control, finished product testing, and batch record keeping. Schedule T GMP is the minimum standard -- not the gold standard.

Better

API compliance with testing documentation

API (Ayurvedic Pharmacopoeia of India) monographs specify: botanical identity markers, moisture content, ash values, extractive values, heavy metal limits, and specific active compound content where applicable. Manufacturers who test against API standards and provide Certificates of Analysis (CoA) offer a higher quality assurance level than Schedule T alone.

Best

WHO-GMP and third-party testing

WHO-GMP certification (issued by the CDSCO -- Central Drugs Standard Control Organisation) meets international pharmaceutical manufacturing standards. Required for export to regulated markets (EU, US, Canada, Australia). Third-party testing by accredited labs (NABL-accredited laboratories) for heavy metals (particularly for Bhasma preparations), pesticide residues, and active compound content is the highest available standard for Indian Ayurvedic products.

The Bhasma quality issue

Bhasma (calcined mineral/metallic preparations) require specific heavy metal testing that goes beyond standard API compliance. The API specifies quality tests for Bhasma including the classical tests (Rekhapurna, Varitara, Apunarbhava) and modern tests (particle size, heavy metal screening by ICP-MS). Not all licensed manufacturers perform the full ICP-MS heavy metal panel. For Bhasma preparations specifically, choose manufacturers with documented ICP-MS testing and third-party verification. Kottakkal Arya Vaidya Sala and Baidyanath are generally considered the most rigorous for Rasa Shastra preparations.

Outside India -- regulatory status varies

The regulatory status of Ayurvedic medicines sold outside India varies significantly by country. In the EU, Ayurvedic preparations must be registered under the Traditional Herbal Medicinal Products Directive (THMPD) for therapeutic claims. In the US, they are regulated as dietary supplements (not medicines) under DSHEA -- with lower testing requirements than pharmaceutical standards. In Australia, TGA registration is required for therapeutic claims. Bhasma preparations containing metals face the most regulatory scrutiny in Western markets. Always check the regulatory status in your country before purchasing.
