When you are out in nature it's important to be aware of plants that can cause rashes, burns and blisters. Poison Ivy, Wild Parsnip and Giant Hogweed are all invasive plants that grow in the region and simple contact with your skin can cause a reaction.
Prevention: Stay on trails when walking or hiking to avoid contact with these plants. Even when they are dead they can still have the oils or saps that cause a reaction, so take caution any time you are handling plants in an area that could have them. These substances can also be transferred from boots, blankets, clothing, pets or other people who have the oils/saps on them to you, so be sure to wash any items that may have been in contact with one of these harmful plants. If you spot some of these invasive, harmful plants on City of Ottawa property, you can report them to be removed HERE or by calling 311. If these plants are on your private property, look into safe removal techniques, take precautions, and do not burn the dead plants as this can cause the offending compounds to become airborne and can cause irritation to anyone who inhales it.
Treatment: If you do come into contact with Poison Ivy, wash your hands and any exposed areas as soon as possible with soap or detergent and water, or with rubbing alcohol (if no soap and water available). Ensure you clean all areas that may have oils on them including under your fingernails. If you get sap from Wild Parsnip or Giant Hogweed on your skin, keep it covered from any sunlight (until you can wash it off, as the combination of sap and sunlight can cause serious burns). Wash the exposed area with soap and water as soon as possible and keep it out of the sun for the next 8 hours. If you do develop a rash or mild burn you can use calamine lotion, a cool damp cloth and/or antihistamines to reduce your pain and irritation. If it does not improve after 3-4 days or if it gets worse, you can call the clinic to be assessed by our triage nurses who can give you further advice.
