World Health Organization has said that there are no alternate medicines to cure COVID-19.
The advisory by the World Health Organization states that eating pepper and garlic does not prevent or cure COVID-19. The apex body does not recommend self-medication with any medicines, including antibiotics. A WHO official too confirmed that while home remedies like lemon, ginger, honey could have soothing effects, or provide reassurance during an illness, there is currently no cure for COVID-19. Hence the claim does not hold any truth.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
