14 Easy and Quick Home Remedies for Poison Oak

Poison oak and also the poison ivy and poison sumac are weeds that can be found throughout the United States except in Hawaii, Alaska, and certain desert areas of Nevada. If you stay in the US but not in the three mentioned areas, you may be well aware of the itchy rash that you can get when you come in contact with poison oak, poison ivy or sumac. If you are allergic to one of these plants, you will be allergic to all of them. The culprit is the colorless oil called urushiol found in poison oak and the other two plants as well. If you cut, crush, step on, sit on, grab, roll on, kick, or disturb these poisonous plants in any way, you will trigger the release of this toxic oil which will ooze from the damaged leaves or stem. If you just brush past the poison oak, you may not get itchy rashes but if you somehow come in contact with its oil, you would badly need medicines or home remedies for poison oak rashes. Once the poisonous oil penetrates your skin, rashes will appear within 12 to 48 hours in the form of small bumps and then will get enlarged into itchy blisters. Face, arms, hands, legs, and genitals are the parts affected most but other parts are not immune to it.
