‘GMP certificate for coronil doesn’t guarantee its efficacy’ Patanjali’s Coronil certification doesn’t guarantee efficacy in Covid cure: Govt (PTI) Share Via Read Full Story New Delhi: The Ayush ministry on Monday said Patanjali’s good manufacturing practices (GMP) certificate does not vouch for the efficacy of the drug for any disease condition. The clarification comes a day after the World Health Organization (WHO) said in a tweet that it had not reviewed or certified any traditional medicine to treat or prevent covid-19. “Patanjali has only a GMP certificate from the apex drug regulator, the Drug Controller General of India (DCGI), and a manufacturing licence from the Uttarakhand state government as a prophylactic drug," a senior Ayush ministry official said, seeking anonymity.
