Colgate white toothpaste [baking-soda &peroxide]

Neutrogena acne-wash soap
Now, had I some Jewelweed-based soap at the time, the rash would have gone-away much-more quickly. Recently picked-up some Burt's Bee's ivy-relief soap with Jewelweed extract inside.
I'm stocking all 3 items + B.B.'s soap in my med kits as well.
I’ve also heard to use the orange shop soap, Goop, to get the poison ivy oil off your skin before the rash starts. FYI, don’t take a bath but a shower after coming in from anywhere that might have poison ivy. I made that mistake once and ended up with it from head to foot. Also, wash your hands in the sink before showering.
