Poison Ivy Can Cause A Severe Allergic Reaction, But Is Seldom Fatal
Poison ivy is a very common plant in America (although rare in Europe), and most people are allergic to it.
One form of poison ivy grows low to the ground, 6 inches to 30 inches high, usually in groups. The other form is a "hairy" vine that climbs up round a tree. Both have stems with 3 leaves, hence the saying "Leaflets three, let it be."
The poison ivy plant contains an oil called urushiol which bonds to skin when it comes in contact with it. The allergic reaction results in an itchy, red rash. It can arise by touching the plant itself, or touching anything which may have come into contact with the plant, such as clothing, shoes, gardening tools and pets, if they have been contaminated by the poison oil.
Even burning the poison ivy plant may cause an allergic reaction, as the oil from the plant is carried in the smoke.If the smoke then inhaled, this rash will appear on the lining of the lungs, causing extreme pain and possibly fatal respiratory difficulty.
If poison ivy is eaten, damage may be caused to the digestive tract, airway, kidneys or other organs.
In rare cases, poison ivy reactions may require hospitalization.
A rash will usually begin to appear 1 to 2 days after contact with urushiol. The affected area will become red and swollen; a day or so later, small blisters will form, and the rash will become very itchy. The blisters should not be scratched, in case bacteria under the finger nails get into the blisters and cause further infection. After about a week, the blisters will normally start to dry up and the rash will start to go away but in severe cases, where the poison rash covers large parts of the body, it may take much longer.
The skin area contaminated with Urushiol, which bonds to the skin within minutes, should be washed in cold water as soon as possible to wash away the oil. Products that contain solvents such as mineral oil (brand names: Technu, Zanfel) can also be used to remove urushiol from the skin.Because urushiol can remain active for several years , anything which has come into contact with it should also be washed, such as clothes, shoes, tools and camping, sporting, fishing or hunting equipment.
The poison ivy rash it will disappear in 1 to 3 weeks. Itching may be relieved by hydrocortisone cream (brand name: Cortizone-10), calamine lotion, antihistamine tablets (one brand name: Benadryl). or oatmeal baths.
A doctor should be called if you have a fever over 100 F (37.8 C), or the rash covers large areas of your body, or the rash is in your eyes, mouth or on your genital area, or there is pus coming from the blisters or the rash does not get better after a few days.
