There are no medicines or remedies that have been shown to prevent or cure COVID-19.
Taking hot water with lemon and turmeric, vitamin supplements, foods with garlic and ginger, apple cider vinegar, or gargling with salt water do not help and cure the coronavirus.
Drinking or gargling warm water with turmeric and salt can help with a sore throat, cold, and flu, but it will not protect against COVID-19 infection. The World Health Organisation (WHO) states that there is no scientific evidence that turmeric or salt water helps prevent COVID-19. It further recommends that we much consume more fruits and vegetables to maintain a healthy diet, in order to boost our immune system. A vaccine for COVID-19 has not been discovered yet, and currently, several potential vaccines are at different stages of clinical trials across the world.
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.
