>>2768508you can't. that plants is spawn by the devil itself. that one and the ticks.
you can get OTC at Walmarts Ivarest - either spray or cream (spray is easier to apply) and spray yourself every 20 minutes. It will remove the itch.
If you're thinking to skin yourself and have another skin grow up anew, here's how you do it, but don't recommend: mix bleach with water (not sure of proportions) and spray yourself. It will damage the skin and the blisters with it, too.
Buckle up, you'll be in for a rough ride for 2 weeks. It will heal prob in a month. As this anon says here
>>2768513, you still might have poison ivy oil on your skin. get a cloth and a dishwasher detergent and scrub yourself, even over the blisters. The oil is invisible; scrub yourself like you would have motor oil or cooking oil on you. it doesn't go away at the first wash, does it?
