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.

We have also compiled a list of sellers making false COVID-19 treatment claims. It appears that these sellers are taking advantage of the coronavirus pandemic to make a quick buck. The products from them, such as chlorine dioxide (a bleach solution marketed as Miracle Mineral Solution or MMS) and colloidal silver, should be avoided because they can harm your health.
