A practical guide for brand owners covering raw material testing, in-process controls, GMP requirements, certificates of analysis, and batch records.
Quality control in Ayurvedic manufacturing begins before a single raw material enters the batch and continues through in-process monitoring, finished product testing, and archived batch documentation. A GMP-certified manufacturer should be able to show a buyer documented evidence at each stage. Knowing what to ask for is the most practical step a brand owner can take to protect their product and their customers.
Ayurvedic formulations are often named after a primary herb whose substitution, even with a closely related species, changes the pharmacological profile. Ashwagandha (Withania somnifera) and its common adulterant Withania coagulans look similar but are botanically and chemically distinct. Bala (Sida cordifolia) has well-documented market substitutes that may not carry the same classical indication. In mineral preparations such as Bhasma, the purity of the starting material is directly tied to the safety and quality of the finished product.
A GMP-compliant manufacturer should apply organoleptic identification (visual, olfactory, and tactile inspection by a trained botanist or Ayurvedic pharmacist), botanical microscopy, and chemical spot tests as a minimum for each incoming raw material lot. For critical or high-value inputs, thin-layer chromatography (TLC) or HPLC identity confirmation is standard practice at well-equipped units.
Ask any manufacturer you are evaluating: do you maintain authenticated reference standards or voucher specimens for identity comparison? Do you issue a written raw material release certificate before a lot enters production?
In-process controls verify that the manufacturing process is proceeding as specified at each critical step. The checks differ by dosage form.
For churna: mesh size verification at the sifting stage and moisture content testing before blending and packing are standard minimum checks. For vati and guggulu: binder consistency, individual pill weight uniformity, and loss on drying at defined intervals are typical. For taila: the classical lepa-paka stages described in texts such as the Sharangdhar Samhita specify practical tests (the water test, the snap test of the paste) that a skilled manufacturer applies, alongside instrumental checks such as refractive index and specific gravity at batch completion. For asava-arishta: fermentation progress monitoring, including alcohol content, pH, and clarity, at defined intervals is essential before the batch is closed.
A GMP unit records every check in a batch manufacturing record (BMR) that traces each action, measurement, and deviation during production. If a parameter falls outside specification, the BMR must document the deviation and the corrective action taken. This trail is the core of any quality system.
When evaluating a manufacturer, ask to see a sample BMR (with commercial details redacted if necessary) to confirm that in-process documentation is systematic and contemporaneous, not retrospective.
Schedule T of the Drugs and Cosmetics Act, 1940, sets the minimum standards for Good Manufacturing Practice in Ayurvedic, Siddha, and Unani drug manufacturing in India. Key requirements include:
Holding a valid AYUSH manufacturing licence and a GMP certificate issued by the state drug authority indicates that the unit has been inspected and found to meet these baseline standards. GMP certification is a floor, not a ceiling. Ask whether the certificate is current and whether the manufacturer has been re-inspected within a reasonable period.
For the broader regulatory context, including licence types and the role of the AYUSH Ministry, see our companion post on Ayurvedic manufacturing licences in India.
A certificate of analysis (CoA) is a document issued for each batch of finished product, confirming that it has been tested against specified parameters and meets release criteria. For Ayurvedic products, a well-prepared CoA typically includes:
Raasa Ayurveda provides a certificate of analysis with every consignment. When sourcing from any GMP-certified manufacturer, requesting the CoA before releasing payment is standard practice. A manufacturer unwilling to provide one should be treated as a significant supply chain risk.
Batch records are the complete set of manufacturing and quality documents associated with a specific production run. They include the batch manufacturing record, the batch packaging record, raw material release certificates, in-process check logs, the finished product CoA, and any deviation or investigation reports generated during the run.
Batch records are the audit trail that allows a recall, a complaint investigation, or a regulatory inspection to trace a product back to its origin materials and process conditions. Under Schedule T, manufacturers must retain batch records for a defined period beyond the product's expiry date. A manufacturer who cannot retrieve batch records for a product you sourced has a fundamental quality system gap. See also our post on third-party Ayurvedic manufacturing for the broader supplier qualification process.
Before placing a bulk supply order with any Ayurvedic manufacturer, request the following five items:
A manufacturer confident in their quality systems will provide all of this readily. If any item is unavailable or refused, that response itself carries important information about the supplier's operational maturity.
For a structured approach to qualifying a new supplier, the post on how to choose an Ayurvedic contract manufacturer provides a full evaluation framework covering licencing, dosage-form capabilities, and documentation standards.

A certificate of analysis (CoA) documents the test results for a specific batch of finished product, covering physical, chemical, and microbiological parameters. It confirms that the batch meets the approved specification and has been formally released for sale. Every consignment from a GMP-certified Ayurvedic manufacturer should be accompanied by a CoA specific to that batch.
Schedule T of the Drugs and Cosmetics Act sets minimum manufacturing standards for Ayurvedic, Siddha, and Unani medicines in India. It covers premises and equipment, qualified personnel with specified Ayurvedic credentials, raw material testing and release, in-process controls, finished product testing, batch documentation, and defined product recall procedures. Manufacturers must be inspected and licenced by the state authority.
Ask the manufacturer to provide a copy of their current GMP certificate issued by the state drug authority. Check that the certificate is within its validity period and that the product categories listed on the certificate match the specific items you intend to order. You can also cross-reference the AYUSH manufacturing licence number with the issuing state authority for independent confirmation.
Many Ayurvedic herbs have closely related species used as trade adulterants that are physically similar but pharmacologically different. In mineral and metal preparations, starting material purity directly affects the safety profile of the finished product. A GMP-compliant manufacturer applies botanical identification, microscopy, and chemical tests to each lot before release into production.
