Rashtriya Kamdhenu Aayog (RKA) Chairman Vallabhbhai Kathiria on Tuesday claimed that 800 Covid-19 patients have been cured through ‘panchgavya and ayurveda’ treatment in a clinical trial conducted in four cities across the country. Kathiria said the clinical trials were conducted on 200 patients each in Rajkot and Baroda (Gujarat), Varanasi (Uttar Pradesh) and Kalyan (Maharashtra) between June and October 2020 in partnership with state governments and some NGOs. The treatment entailed doses of ‘panchgavya’ granules (mixture of cow urine, cow dung, milk, ghee and curd), herb ‘Sanjeevani booti’ and herbal concoction ‘khada’, he said.
