Baba Ramdev's Patanjali, that launched the coronil ayurvedic medicine for Covid-19 patients, has hit back at the IMA after the latter questioned health minister Dr Harsh Vardhan's presence at coronil's launch. A controversy erupted after Patanjali claimed WHO backing for coronil and the WHO denied. Patanjali says the health minister's presence at the launch shows his sincere efforts to provide acceptability to other forms of medicinal systems.
