I had to make the Amish Healer some new Poison Ivy Tincture. I added a few herbs such as Teasle Marker and Solomons seal to make it more "my" formula....and then made a spray. For the spray I added the herbs known for poison Ivy such as Virgina Snake rt., Chickweed, etc.....
In theory maybe the spray will work great, but who knows until it is tried..but we do know the tincture works internally and maybe both would even work better.
