Dietary Supplement Claims and Coronavirus Disease

Currently, there are no vaccines for coronavirus disease 2019 (COVID-19). COVID-19 is caused by the virus, SARS-CoV-2. However, some dietary supplement manufacturers claim to have a "cure" or can treat COVID-19. These are scams because this is a new (or novel) virus and researchers have yet to identify a safe medicine, supplement, or vaccine that can cure or treat this disease.


Between 2002 and 2003, there was an outbreak of severe acute respiratory syndrome (SARS), caused by SARS-CoV. No more cases of SARS-CoV have been reported worldwide. SARS-CoV is about 80% similar to SARS-CoV-2 [Zhou et al. 2020]. In 2014, researchers reviewed medicinal plants and supplements that had anti-viral properties [Lin et al. 2014]. It was found that extracts from 10 medicinal plants either inhibited SARS-CoV's attachment to cells or prevented its growth.


Only one medicinal plant, Houttuynia cordata (common names: chameleon plant and fish mint), was used in combination with western medicine to treat SARS patients [Li et al. 2006]. The study indicated that chameleon plant has the potential to treat coronavirus infections. In general, people widely use Echinacea and elderberry for infections. Research has shown that these herbs may stimulate the immune system. However, the benefits of chameleon plant, Echinacea, and elderberry against COVID-19 are unknown. Research can change that.

Raw Fruit and Vegetable Safety and Coronavirus

According to the USDA, there is no evidence that coronavirus can be transmitted from fresh fruits and vegetables to humans. Nonetheless, it is recommended to follow good hygiene practices. To keep produce safe, follow these steps:

  1. Avoid bruised or damaged produce
  2. Before cleaning produce, wash your hands with soap and water for at least 20 seconds
  3. Only use clean potable water to wash produce; do not use bleach, detergents, or soap because fruits and vegetables will absorb these chemicals and this can harm you
  4. Before peeling a fruit, wash it with clean water and then dry with a paper towel
  5. For produce with a thick skin, use a vegetable brush to help wash away bacteria and viruses
  6. For vegetables like broccoli or leafy greens, soak in clean water for 2 to 5 minutes and then rinse with clean water
  7. Remove the outermost leaves of cabbage and lettuce and then wash with clean water
  8. To remove additional bacteria and viruses, dry produce with a clean paper towel
