I am wondering if you are referring to the human version of the disease Parvo that dogs get? Years ago I was reading an article written by a very famous naturopathic verternarian that Caster Oil kills the Parvo Virus. I had a friend that was a paramedic that had somehow contacted the disease a few years earlier and he had to go thru several blood transfusions from loss of blood. It was very serious. Anyway, shortly after reading this article I had our puppy come down with the disease so I tried giving her caster oil which worked. She was weak for a couple of days but survived to become a healthy dog. My neighbor's dog also had contacted the disease and she spent $2,000 at the vet and the dog died. I have in recent years had 2 other puppies come down with Parvo and just gave them Caster Oil and they were fine. Anyway just thought it might help. I am not sure how the Parvo Virus works but it may stay active in your body. I know that it causes bleeding in the intestines and the Caster Oil kills the virus right out. Caster Oil is very inexpensive and you can purchase it at a pharmacy or alot of health food stores carry it.
