Herbs for poison ivy?

Are there any herbs that help with poison ivy? Maybe herbs that I could make into a compress or salve.

I would break open an aloe leave and put that on.  

plantain leaf would be a great one to smash up and put on the affected area

A cool clay poultice would be nice to draw out the heat and ease the sting.

Ugh, miserable. I don't have advice for after you've gotten the rash already.

But washing with any kind of soap or detergent as soon as possible after exposure will help to prevent rashes in the future. It has worked for me, many times. No special soap needed, just any soap or detergent that can cut oil and wash it away.

Jewelweed (particularly pale jewelweed/Impatiens pallida) sap is considered good for treating stinging nettle and poison ivy.  
I'm growing some this year for the first time with the intent of creating a salve, so I have no personal experience with it yet.

Definitely Jewelweed. Poison ivy and jewelweed often grow near each other in the wild. When I got some native ephemerals from a friend, I got jewelweed too and it's EVERYWHERE now. So, be careful if you plant that it goes in an appropriate spot. Those seed heads are fun to play with (my kids like to hand them to unsuspecting people who scream when they explode) so they get spread easily.

You can smash the plant up (they are really juicy) and smear it right on for immediate relief. If you think you've gotten in something you can smear it on preventatively too and your reaction won't be as bad- it really is a great antidote. You can buy soaps, make infusions, etc- whatever works.
