The systemic poison ivy symptoms, on the other hand, consist also of rashes, however, the itchy rashes are scattered and continue to appear more and more in many spots after the four days of the first patch of rashes. The rashes turn to blisters, they dry out and disappear. Normal poison ivy reaction is when the rashes only appear in areas where urushiol comes in contact with the skin. It bonds with a type of white blood cell called Langerhan’s cells, and from there can spread throughout the body. On skin contact with urushiol, it sinks in and binds to the cell membranes. The urushiol oil enters the bloodstream through the lungs and causes serious blisters and rashes to cover the entire body, even inside the mouth and throat. One common reason for system reactions to poison ivy is inhaling poison ivy fumes. The oil can remain active on any surface for one to five years. It can also get airborne when you burn poison ivy or when tiny pieces of the plant get into the air when you mow or cut the plant. You can get urushiol on you with direct contact with the poison ivy plant, or indirectly through clothing, pets, and outdoor gears. It also is present in poison oak, and poison sumac. It is an oil produced by the plant that’s so potent that doses lighter than a grain of salt can cause blistering rashes. Urushiol is the main culprit to the poison ivy being a nasty plant. It can turn severe blisters that could last for weeks and it can be even life-threatening for some people. But with a systemic reaction, the poison ivy rash rather spreads throughout the body, including to areas that had no direct contact with the plant. When you are exposed to poison ivy, you get these annoying localized rash appearing on the skin where contact took place. If an allergic reaction to poison ivy isn’t bad enough, the systemic poison ivy is even worse.
