As a life long sufferer of cold/flue (once every 3 months bout lasting for over a week), I tried various natural things on myself. I probably have found solution that works for me. Allergy/cold free from 2015-6 ( go only when I deliberately tried to get it to find out if it works) and worked during 2020 too. Even worked for my family too. I even wrote to CDC director about it (but no response). How does one go about does one go about finding efficacy on others? I'm into software so have no clue. tia.
