Itching and burning! FOR SCIENCE!

[Wigmund]

Here's a Ozark folk remedy for Poison Ivy:

The Bud of a Sumac Tree if taken while it is still green can be boiled into a tea, but you have to remove the white broth that forms on top because that part is still poisonous. This will keep you from being allergic to poison ivy, but it needs to be repeated annually when the sumac bud is green.

And then there's whiskey.

You can cure anything in the Ozarks with whiskey, but of course, as with all medicines there are side effects.

So this means that Irish Tea made with Sumac will make you immortal.
