haven't tried this. i don't have Colloidal Silver on hand (one of the few things i don't have yet, i must have bought the whole iherb inventory by now)
also, yes the place here is moldy. i treat with Miracle-Mineral-Supplement every now and then to kill the mold in the air, but because its under the ground it creeps backs in ...
but i didn't have this for the 10 months i lived here, it started just recently.... might be like you say, more symptoms because of dairy.
