76 yrs old here & my Mom is 96 yrs....we have been using this twice per year with Ivermectin being taken the other 10 months per year. Neither one of us go to Drs or hospitals ... never have ... we just do not get sick at all. We do take a couple of drops of Colloidal Silver in the eyes most mornings as well. Spirulina tablets daily too. I just retired (by choice) a couple of yrs ago from being a horse trainer including starting colts & full barn/pasture care & hoof trimming, etc. Alternative medicine has always been our choice.
