How Does Poison Ivy Cause Itchy and Irritated Skin?
Poison ivy is typically found in all provinces except Newfoundland, with at least three varieties found across the country. All parts of the plant contain the poison resin, urushiol. It isn’t necessarily contact with the plant itself that will cause a reaction with your skin, but contact with its sap. In fact, if your pet comes in contact with the sap, you can even develop a reaction from touching their fur.
You’ve probably heard the “leaves of three, let it be” rule, which dictates that a plant with a compound leaf of three—or three distinct leaflets joining together on a single stem—may be poisonous and should be avoided. However, the trouble with poison ivy is that even within this rule, it can take on many different appearances that vary by season or even just by plant. That means “what does poison ivy look like?” doesn’t have the same answer all the time.
Most people will develop symptoms 24-48 hours after coming in contact. Reactions can range from mild itchiness to more severe oozing lesions and fever. Make sure never to burn poison ivy. If the smoke is inhaled, it can lead to potentially fatal respiratory issues.
