Europe. This is a list of the largest cities in Europe by population within city limits. It deals exclusively with the areas within city administrative boundaries (municipalities) as opposed to urban areas or metropolitan areas, which are generally larger in terms of population than the main city.
I'm making my own soap treatment taht will have 22 different natural ingrediants that will first, remove the oils from the deep in the skin (homemade lye & lard soap is good for that) second, dry it out, third, actually cure the poison ivy dermatitis, and fourth, sooth the itching. I sure hope is works.
first, cleanse exposed areas with rubbing alcohol. next, wash the exposed areas with water only (no soap yet, since soap can move the urushiol, which is the oil from the poison ivy that triggers the rash, around your body and actually make the reaction worse). now, take a shower with soap and warm water.
