Green is good, right? Yes, for the most part. But beware of poison ivy, oak and sumac – three green plants that will make you itch like crazy. These plants all cause contact dermatitis, producing redness and rash. The ingredient in these plants that causes such discomfort is called urushiol. This nasty compound is so toxic, an amount required to sit on the head of a pin will cause a rash in 500 people.
Sensitivity to urushiol-containing plants is the most common allergic skin reaction in the U.S. Over half of the population gets affected by poison ivy and its botanical cousins. And poison ivy, oak and sumac aren’t the only plants that contain urushiol. This compound also occurs on mango, cashew nut trees, India’s “ink nut,” the Malaysian rengas tree, and ginkgo trees. I have contracted terrible urushiol-related rash in the rainforest of Ghana, Africa, in Mexico, and in India – all as a result of contact with plants.
If you make contact with any of these plants, the best thing to do is wash thoroughly before reaction occurs. The company Tecnu makes a wonderful line of products specifically for poison ivy and its cousins, and washing with Tecnu soap can prevent a blooming rash. But if you miss out on catching allergy early, there are remedies you can use to help relieve the terrible itching and redness that occur.
Baking soda paste
Found in most kitchens, common baking soda is a great natural remedy for the itchiness associated with a poison ivy rash. To help relieve itching, place 1/2 a cup of baking soda in a bath tub filled with warm water. You can also mix three teaspoons of baking soda with one teaspoon of water and mix until it forms a paste. Apply this paste to the infected area to relieve itching and irritation that’s associated with a poison ivy rash.
Made from the bark of the witch hazel tree, this astringent splash relieves the itch of poison ivy and tightens skin. Wherever you have a rash, apply witch hazel. The cooling, soothing extract will not get rid of the rash, but it will calm it down.
