So like my aunt always uses colloidal silver whenever any of us gets sick and it works like a miracle but I have been reading up on it and it says that you can like turn a gray blueish color from to much exposure, is this true? Also I don't know why but my asthma has been acting up(not related to the colloidal silver) but yeah I don't know what it is??? Like one day I can do fine without any problems the next day I have to use my inhaler just to get up the stairs?
