Colloidal silver helps my migraines too as well as my arthritis. It is the best antibiotic I never take pharmaceutical antibiotics. Skin problems, cuts, warts, fungus anything like that it works wonders.
I have not had the flu for over 45 years, not saying I have taken sliver that long of course but I have a natural immunity I guess, no colds either. Don't take flu shots either. Some hay fever in the summertime when the wheat is pollinating especially, the silver works for that too. So, with all the hype about the evils of silver I can testify it is very beneficial in a number of ways.
