I criticised Patanjali Ayurveda’s claimed cure for COVID-19 for making unsubstantiated claims of efficacy. The drugs it is offering are untested and unproven. They haven’t proven their mettle in a well-conducted adequately sized randomized controlled trial. The proponents of Ayurveda, however, ask – can Ayurveda, or alternative medicine in general, be evaluated in the same way as modern medicine? I argue that science is science: you cannot have different goalposts.

The Hindu interviewed me on this topic.
