I was still affected by allergens and after having a cold or flu I usually came away with a sinus infection that was increasingly resistant to antibiotics. Most recently I had tried a course of treatment with a Chinese herbalist and acupuncturist--which helped some until getting a slight cold which sent me back to square one. Then, while searching the web, I happened upon your site, and now feel I have found the means to be and stay well from now on! When I received my first bottle of your colloidal silver, I was suffering from severe headaches from the infection, combined with the unusually high pollen this spring. I drank two teaspoons and dripped two droppers-full into my nose before sleeping, and woke up for the first time in weeks with no headache or face pain!!! I continued to feel better over the next days, and resolved to try it for the six to eight weeks suggested for a chronic condition--both orally and in my nostrils morning and night. It works and I am now free from these ailments.
