**In the medical literature there are different grades of evidence. One of the most basic forms of evidence is considered in-vitro studies. This means looking at how cells behave in a laboratory environment and making hypotheses to how this may function in a living organism like a human. Unfortunately, much of the literature we have on botanicals in-regards to coronaviruses like COVID-19 and SARS is based on these basic research methodologies. However, these mechanisms are plausible and should be considered when consulting with your healthcare provider.
