Is Coronil an immunity booster or Covid-19 cure?

Dr BS Tomar, Director of NIMS hospital where trials for Patanjali's Coronil medicine took place has made a stunning claim that the trials done at his institute were limited to the impact of Ayurvedic medicines on immunity of Coronavirus (Covid-19) patients. He said that he never made the claim that Coronil can cure Covid-19. He further added that questions regarding treatment of Covid-19 through Coronil must be directed to Patanjali.
