Dayton: Dermatologists have come up with preventative tips for gardeners after seeing how common plants can leave their mark on the skin and cause a host of mild to even severe skin reactions.Dermatologist Julian J. Trevino, MD, FAAD, associate professor of dermatology at Wright State University Boonshoft School of Medicine in Dayton, Ohio, discussed common skin reactions that can occur from contact with plants, including effective treatments and preventive strategies."While most of the skin reactions resulting from direct contact with a hazardous plant are more of a nuisance than anything else, there are some instances where the reaction can affect the entire body and pose a potentially more serious risk," Dr. Trevino said."For example, people who are allergic to plants or have sensitive skin that is prone to eczema or atopic dermatitis may experience more severe or long-lasting effects that require medical attention," he stated.There are many outdoor plants that can cause an adverse skin reaction simply by brushing up against them.One group of plants in particular that causes toxin mediated urticaria (hives) is stinging nettle plants, which have sharp hairs that produce irritants.These irritants are chemicals, such as histamine or acetylcholine, which usually cause an immediate outbreak of hives within 30 to 60 minutes upon exposure.Most people would experience a mild reaction with hives that resolve on their own in a few hours.Dr. Trevino also explained that people who handle food frequently or those with a tendency toward eczema can develop an allergic reaction to plants known as immunologic contact urticaria.This reaction usually results from susceptible individuals coming in contact with various fresh fruits and vegetables, herbs, nuts, shrubs and grasses.In this instance, a person usually experiences itching and hives within 30 minutes.In its more severe form, this reaction can involve not only hives on the skin, but also swelling in the throat, lungs or gastrointestinal tract that requires immediate medical attention.
When a person with poison ivy allergy contacts the plant, Dr. Trevino explained that time is of the essence to prevent a rash. The area that has been exposed should be rinsed off immediately with water.This can remove at least some of the resin before it is absorbed in the skin.To treat a rash caused by poison ivy, lukewarm baths and soaks with products containing aluminium acetate (a type of salt that dries up the weeping and blisters), and topical preparations such as calamine or topical steroids are helpful.While oral antihistamines will help alleviate itching and skin irritation, topical antihistamines should be avoided - as some people are allergic to them and the rash could get worse."In some cases when a rash is severe or covers a large area of the body and is not getting better with over-the-counter therapies, a dermatologist may prescribe strong topical steroids or a course of steroids taken orally," Dr. Trevino added.To minimize the risk of such skin reactions, Dr. Trevino recommended the following tips:1. Wear protective clothing whenever possible - including gloves (preferably vinyl gloves), long sleeves and long pants tucked into socks.2. Apply an over-the-counter barrier cream or lotion containing quaternium-18 bentonite to exposed skin before going outdoors. This helps prevent urushiol from poisonous plants from contacting the skin.3. Avoid poisonous plants (remember this phrase: "leaves of three, let it be").ANI
