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.
Wash anything that comes in contact with poison ivy to remove the oil. As you know, the rash is very itchy. It usually lasts about three weeks. For mild cases, you can use cool compresses, over-the-counter oral antihistamines, and hydrocortisone cream applied to the skin. For more severe cases, see your doctor.
