Causes of Poison Ivy

Poison Ivy dermatitis is one kind of allergic contact dermatitis, i.e, it occurs when a foreign allergen compels the body’s immune system to respond to it. In poison ivy dermatitis, the body quickly absorbs Urushiol, the plant oil, which contains allergens. The body’s immune system then produces anti bodies to battle against the allergens. The anti bodies release certain chemicals that cause damage to the surrounding cells which manifest as the physical symptoms of an allergic reaction.
