Query: The only thing that works

These really work! I had a bad case on my face and neck that jewelweed was unable to clear up. Within only one hour of taking these pills the itching stopped completely. The next day the skin started to heal. After only 4 days I could stop taking the pills without rebounding. These pills contain a tiny amount of the poison ivy toxin, which I guess confuses your immune system.
