Also called Poison Ivy soap. 

This 5 oz. bar is our basic homemade Soap made with pure Jewel Weed Extract! If used within about an hour after being exposed to Poison Ivy, it will remove the oils so you do not break out. If you are unaware that you have been exposed and break out in the the dreaded "rash", washing with this soap will help heal it much faster. Use it on your whole body, including the face. If you are very susceptible to getting a rash from any Poison Ivy , Oak or Sumac, put the bar in your backpack when hiking or camping. Maybe keep it in the glove box of your car. The key is to act quickly and wash the affected skin right away.
