Thanks for your response. So you are essentially saying that tollovid worked for you as a prophylactic and you believe it will help the immune system during the first week or so of someone having covid, agreeing with the article. Am I right? Ohm seems to believe that it suppresses the immune system and does the opposite if I’m understanding him correctly, and Respert is skeptical of most herbals as well. I certainly don’t want to suppress my immune system if I get covid. So should we order tollovid or gromwell root powder ( because it’s cheaper) or save our money and buy neither? Also, the other active ingredient is lecithin. What does that do or is it mainly the gromwell root?
