An Old Foe

Today we meet again Poison Ivy.  I thought I had grown past you but you still haunt my legs when I walk around in shorts. 

I don't understand the treetment.  Calimine lotion dries out poison ivy to help get rid of it faster.  Yet I have eczema which is extremely dry skin.  Shouldn't I be immune to poison ivy?

I guess logic just doesn't play out here :)
