*waves* I bet we are close!I'm in Nowthen, welcome to the banana belt! You must be very close to me...
JEWEL WEED if you can find it anywhere. If it is the actual weed break open the stem and apply it to the poison ivy. Works like a charm. Maybe it would be available in essential oil form? Good stuff.
I used to try and find the ripest seed things as a kid.... Was fun to make them explode.
As for the poison ivy... Blending the touch me nots up with plantain works really well. Haven't used it in a while so I forget the exact recipe, but I do remember it worked.
I didn't know about jewel weed, but you almost certainly have plantain around you. Here are a couple links/recipes that you could adjust to ingredients on hand.
