Since the beginning of the COVID-19 epidemic, several statements have been propagated about “immunity boosting” substances such as mustard oil, hydroxychloroquine and tea; alternative remedies claiming to provide either immunity or cure; and remedial effects of cow urine or even taweez. Some of these assertions were also supported by a few government functionaries at the centre and in various states. We, the undersigned, wish to put the following scientific facts in the public domain.
–> As of now, no scientific studies show that any substance boosts the immune system specifically against COVID-19, be it modern medicines like hydroxychloroquine or homeopathic solutions like Arsenicum Album D30 or Ayurvedic preparations.
–> Scientific evidence for the efficacy of any of these substances can only be obtained by rigorous testing through randomized clinical trials with COVID-19 patients, and additional laboratory analyses. Anecdotes of cure or temporary relief from symptoms or usefulness against similar diseases are not scientific proof of efficacy against COVID-19.
–> Specific immunity against a bacterium or a virus can only arise in two ways. Either we were infected and recovered from the illness, or we are vaccinated; in either case we develop antibodies that can target the specific virus or bacterium.
