Yoga teacher Ramdev's Patanjali Ayurved never claimed it can cure COVID-19 with its medicines, Coronil and Swasari, the firm's Chief Executive Officer Acharya Balkrishna said on Tuesday, adding it just shared the favourable outcome of clinical trials on patients. The Centre had barred the firm from advertising the products after Ramdev, in a sensational claim last week, said they cured 280 patients within days in trials.
