Sweetgum balls contain the same active ingredient that Tamiflu contains, which is shikimic acid; It kills viruses including SARS-CoV-2
Sweetgum contains small amounts of shikimic acid, which is the starting point in the industrial manufacture of Tamiflu, a drug for treating influenza. However, there is no evidence that shikimic acid has the same effect. Tamiflu targets a specific protein found in flu viruses, so it doesn’t work against the virus that causes COVID-19, and neither does shikimic acid. [...] The video also makes reference to using sweetgum balls to treat COVID-19. However, as mentioned previously, Tamiflu works by targeting a specific protein in the flu virus. There is no equivalent of the neuraminidase protein in the SARS-CoV-2 virus, so the drug cannot act in the same way that it does with flu[4]. To claim that shikimic acid can help treat COVID-19 would need evidence from research. In summary, shikimic acid is not the active ingredient in Tamiflu. Shikimic acid is chemically altered to produce Tamiflu and will not have the same effect. The amount of shikimic acid in sweetgum balls is very low and it is difficult to extract.
