What Are Poison Ivy, Poison Oak, and Poison Sumac?
Poison ivy, poison oak, and poison sumac are three types of toxic plants that commonly cause allergic skin reactions. Poison ivy can grow as a shrub or vine and typically stands up to three feet tall. It typically has three leaves coming off one stem, which are usually a light greenish-yellow in the spring and summer but turn red in the fall. Poison oak also grows as a shrub or vine and typically has clusters of three leaves. It is most commonly found in the western United States and is reddish-brown in color. Poison sumac is a woody shrub native to wet areas of North America and can reach up to 20 feet tall with large clusters of 7-13 leaflets.
Allergic contact dermatitis is caused when someone comes into direct contact with any of these poisonous plants, either through touching them directly or indirectly by coming into contact with their oils. Symptoms usually appear within 12-48 hours after exposure and include an itchy rash, redness, swelling, and blisters. To reduce symptoms, cool water wet compresses or aluminum acetate (Burrow’s solution) may be applied for 20 minutes at a time several times each day. Severe reactions may require prescription medications from your doctor.

What causes an allergic reaction from Poison Plants?
An allergic reaction can be caused by the resin found in plants, which contains an oily substance known as urushiol. This chemical is easily transferable from plants to other objects, including toys, clothing, and animals. In some cases, it can remain active for a period of up to a year or longer. It is important to be aware that the oils from these plants may also be passed on from clothing and pets, and can even be present in smoke produced following the burning of such vegetation.
What to do when exposed to Poison Plants?
When exposed to urushiol, individuals can develop an allergic reaction ranging anywhere from minor skin irritation to difficulty breathing and swelling of the face or throat. If any signs of a severe reaction are noticed after exposure, medical attention should be sought immediately so the best course of treatment can be applied. With skin contact being the most common form of exposure, proper hygiene such as washing hands immediately after touching plants or wearing protective gloves while gardening should always be taken into consideration when dealing with vulnerable vegetation.
