Rashes From Allergic Reactions and What To Do

Poison Ivy Rash

A poison ivy rash comes from the beneficial plant for other plants since it plays an important role in the food chain within the wild. However, it is one of the avoided plants due to its dangerous effects not only on the skin but also to other parts of the body. The effects can start as a rash and spread throughout the body if not treated right away.

Poison ivy rash is one of the common allergic reactions affecting nearly 85 percent of the population according to Weill Cornell Medical College. It is known as the Urishiol-induced contact dermatitis that can cause mild to fatal effects on the person exposed to the oil and resin produced by the poison ivy plant.

Causes

A clear fluid called Urushiol is contained under the poison ivy’s outer covering and when the plant is damaged or injured it is excreted out together with other chemicals in the form of sap. And when an object, either be it a clothing or a tool, comes in contact with it, the sap adheres and remains on it. Smoke inhaled from burned poison ivy can also cause rash on the linings of the lungs.

If a person comes in contact with the Urushiol, the oil attaches on the skin and acts as a hapten, binding and reacting with the proteins on the skin cells triggering the immune responses of the body to attack cells thus causing allergic reactions.
