This summer millions of Americans will have unhappy encounters with poison ivy. For most people, the result is a patch of itchy bumpy skin that goes away after a few days to a week or so. Unfortunate others will develop a serious reaction that includes severe itching and swelling.
The very best way to not get a case of poison ivy is to avoid the plant and its culprit – urushiol, an oil that causes the allergic reaction. It’s on the plant’s leaves, in the vines and the sap.
Avoiding urushiol is a surefire way of avoiding a poison ivy rash, but many people have trouble identifying the plant. Fortunately, poison ivy has a secret. Knowing it helps people avoid the plant.
