I have used silver plasters for all cuts and grazes for a while now and only a few days ago came across ProColloidalSilver. I worked in Complementary Medicine for many years but hadn't heard about CS. I've received my first order and am awaiting a call back from the Compant to check how much to use etc. My husband has just started a heavy cold, the first all through the winter months so from tonight, hopefully, he will start taking the CS. I also have arthritis so we will see the effect CS has on that as constant painkillers are not the answer! Great delivery time so we are looking forward to using and ordering more - perhaps the smaller spray bottles for holidays and those awful mosquito bites! Let's hope it can help those too.
