partialy true proffessor
the Urushiol can be spread by using soap if it hasn't already penetrated your skin...
Urushiol oil is strange stuff...it penetrates your outer skin layer
in like ten minutes then laying upon your subcutaneous red layer sends up the blister....they recommend using just water or rubbing alcohol to remove it from your skin rather than soap when first exposed.
Paul , ortho makes a poison Ivy killer that doesn't kill neighboring plants or trees like round up does... active ingredient : triciopyr
another remedy is (a powder of) Tide laundry soap and water to make a thick paste ...leave on 20 minutes ..stops itching too
i think personally that the blister fluid has a small amount of
Urushiol oil in it and the blister is the bodies method to expel it
like a mini volcano getting rid of lava.
