It's great on rashes. It seems to stop cold sores from fully developing into actual, visible sores.
I take care of 2 handicapped clients. Works great around feeding tubes through the abdomen, preventing infection.
My wife took it when she got pneumonia from her Swine Flu Shot. She's an RN and was required to have it for work. This is subjective since I have no idea how it would have turned out if she hadn't taken CS.
That's a few examples in my household.
