It all starts with the oil called urushiol found in these plants causing a blistering rash to occur within 12 to 72 hours after contact with the oil. This is known as allergic contact dermatitis due to the oil acting as an irritant to the skin. Fortunately, the rash is not contagious and usually goes away within a few weeks. However, swelling can be a sign of a severe reaction, particularly if it involves swelling of the face or eyes. Difficulty in breathing or swallowing warrants an immediate trip to the emergency room.
Preventing contact with these poisonous plants is the solution. Taking necessary precautions is a big step in reducing the misery of an aggressive poison ivy, oak or sumac rash.
· Avoid contact with the plants
The saying “leaves of three, let them be,” is sage advice. In order to avoid contact you must know what they look like and be looking for them whenever you are outdoors. When hiking, stay on cleared trails or pathways, avoiding walking into wooded areas or low-lying brush. If gardening or pulling weeds, be mindful of where your legs and hands are and what you are touching. If pitching a tent for camping, do so in an area cleared free of these plants.
· Cover-up when outdoors
Spending time outdoors means you may be in an area of where poison ivy, oak, or sumac like to spend time also. If you are going into a wooded area, gardening or being near fence posts, trees or other fixtures ivy likes to climb on, protect your skin by wearing socks, boots, pants, long sleeves, and vinyl gloves.
· Kill the plants
Inspect your yard for these ‘leaves of three’ plants. If spotted, apply an herbicide to kill them. It is recommended not to burn these plants as the usushiol can be carried by the smoke which you breathe in and could cause a serious systemic reaction throughout the body.
· Wash hands after being outdoors or petting animals
Washing hands and arms using soap and cool water within 30 minutes after exposure can help wash away most of the oil preventing the harmful resin form reacting with your skin. If you feel you may have been exposed on other areas of your body, take a shower – this can go a long way in preventing or at least reduce the severity of a rash.
Animals like dogs or cats may have walked through an area where the poisonous leaves brushed against their fur containing the oil. If you pet them, the oil gets onto you. Always wash your hands thoroughly after playing with your pets.
· Clean all contaminated objects
Promptly wash your clothing that comes into contact with poison ivy, oak or sumac in a washing machine. Anything else that has been contaminated – jewelry, garden tools, shoes, shoelaces – need to be washed as soon as possible.
· Use a barrier cream
A good way to protect yourself is to use a cream creating a barrier between your skin and the oily resin. Look for over-the-counter products that will form a protective blockade against these poisonous plants.
