Ethanol content in traditionally fermented ayurvedic formulations: Compromised Good Manufacturing Practice regulations - compromised health.

BACKGROUND

A large part of the population of India prefers the traditional medicine (ayurvedic formulations) for primary health care. However, the effective quality control of herbal medicine is still a big challenge. Numerous reports indicate noncompliance with Compromised Good Manufacturing Practice (GMP) guidelines by the manufacturers which may lead to adverse drug reactions or toxic effects. Asava and arishta are the classical herbal dosage forms wherein fermentation occurs during production leading to the generation of ethanol. The presence of ethanol in these preparations may lead to their misuse. The self-generated ethanol is responsible for extraction of active constituents and acts as a self-preservative. As the procedure for preparation for asava and arishta is same, the ethanol content is also expected to be the same irrespective of the manufacturer.

OBJECTIVE

The objective of the present study was to assess and compare the ethanol content of some traditionally fermented ayurvedic formulations available in the market.

METHOD

In this study, 20 formulations from 3 different manufacturers available as over-the-counter products were obtained and their ethanol contents were determined using gas chromatograph with flame ionization detector.

RESULTS

Statistically significant differences were noted in the ethanol content of various ayurvedic formulations. A simple, less time-consuming, economic, and validated gas chromatographic method for estimation of ethanol in fermented ayurvedic formulations was also developed successfully in present study.

CONCLUSION

The data generated during study reflected poor compliance of GMP guidelines by the manufacturers and hence the quality is being grossly compromised posing a safety hazard.
