Well, I don't use this therapy any more Charlie; but I did study a lot while I was trying it. There is even a homeopathic version of its use. Do you believe in homeopathy? Hasn't helped me much; but I just don't have patience for it. I don't even get flu shots since 1964. I consider that a form of homeopathy too.
In the homeopathic version, you take a few drops of urine, dilute it, dilute it again; and use it for colds, flu, etc.
I understand, from my RN sister, that it is used in hospitals for years too.
