There’s a saying in North America for poison ivy: “Leaves of three, leave it be.” Poison ivy, as the picture shows, has the infamous three leaves on a stem. Many people (but not everyone) are allergic to the oils the leaves produce. Unlucky wayfarers come across the ivy usually in forests, overlooked fence corners or in neglected flower beds. Rub against the plant’s leaves and the oils will give you a rash, blisters and itchy skin.
Gardeners must cut the ivy carefully, bag it and throw it away. You never burn the ivy–the smoke carries the oils and if you breathe it in, a reaction can happen internally. Clothing and skin must be washed immediately. Then bring on the pink Calamine lotion and prepare for a couple of weeks of healing while dodging inquiring stares. Avoid questions of people asking why exactly you look like a pimply young piglet and smile at the ignorant treating you like a contagious leper.
