As far as colloidal silver is concerned, I’ve done a lot of research on this, and it’s my opinion that there’s simply too much hype with little fact. I’ve also read research about certain colloidal silver products containing virtually no silver in them but containing protein stabilizers, which shouldn’t be needed if it is genuine colloid. The stabilizers can also act as antigens triggering various allergic responses.
In the end, no one will be able to tell you whether you should try it or not, but I doubt you’ll find anyone on the forum who has used it with real success as far as curing a Candida infestation.
I know you’re talking about making your own, but if I were you I would research further and try to find proof that it can help Candida to reach a cure before investing my money.
