Yoga teacher Ramdev today released a research paper on what he called the "first evidence-based medicine for COVID-19 by Patanjali", Coronil, in presence of Union Health Minister Harsh Vardhan and Union Minister Nitin Gadkari. Ramdev said that the research paper would clear all "suspicions" related to Coronil, which Patanjali says is a medicine for Covid. "When we launched Coronil, people raised questions on its validity and asked if we followed scientific parameters. People think research can only happen in foreign countries. With this research, we have cleared all suspicions about Coronil," he said, according to news agency ANI.
