Ramdev-promoted Patanjali Ayurved launched Coronil on February 19 Highlights WHO had said it hasn't certified any traditional medicine The opposition citing WHO's clarification attacked the centre New Delhi: Coronil, a medicine that claims to boost immunity against COVID-19, developed by yoga guru Ramdev-promoted Patanjali Ayurved has run into a controversy over claims of certification. At the launch event on February 19 where Health Minister Harsh Vardhan and Union Minister Nitin Gadkari were also in attendance, the Patanjali product was billed by the company as the "first evidence-based medicine for COVID-19". Written on a big poster behind the table where Ramdev and Union Ministers sat were the claims that the "medicine" was CoPP and WHO GMP certified - meaning it holds a certificate of pharmaceutical product (CoPP) and is recognised by the World Health Organisation's Good Manufacturing Practices (GMP). Both these standards approximately define quality assurance in medicinal products.
