My son has had irritation on half of his face & scalp for many, many years, following a massive dose of shingles. Pain, itching, creepy-crawly sensations etc. I suggested he try this colloidal silver with aloe vera (as nothing has ever helped). He was stunned. He could not believe it. Had barely finished applying the gel & all the irritation disappeared. He didn't have to reapply for a week. And none needed since! I use this gel for mosquito bites which itch unbearably. It keeps me sane!
