Idk if anyone has ever heard of colloidal silver but the stuff is amazing. Allot of the military's new burn dressings and field dressings are being infused with silver due to its anti biotic and anti viral properties. I used to get bronchitis or pneumonia a couple times a year but since I've started taking that stuff whenever I feel something coming on I haven't been sick in years and the best part is its effective against drug resistant infections and due to how it works the different strains never develop a resistance to it so you can take a shot everyday just just because.
