Poison Ivy Season
Saturday, July 3, 2010 at 4:40PM
Summer is here and so is the Poison Ivy! I live on the sand prairie in Wisconsin close to the Mississippi River and it proves to be a constant battle to control this obnoxious plant. Well, there really is no controlling it because it is thriving here! The hot and dry weather, along with the sandy soil, provide a perfect environment for spreading. I’ve even noticed the leaves are growing much larger than just a few years ago.
Some folks in the area spray every year, but it still comes back. I’ve heard digging it completely, roots and all, is the only way to get rid of it. Since there are a couple acres of it, it’s not something I’ll get around to doing anytime soon. Even spraying would be too much work, not that I ever spray anything! I don’t mind it really; not that I like it, but it does offer some protection on the borders of our property. I respect it and I do stay out of it!
The botanical name for Poison Ivy is Toxicodendron radicans, also known as Rhus toxicodendron and Rhus radicans.
Poison Ivy displays three leaves, in an alternate leaf arrangement. The leaves are generally a glossy green and smooth and some leaves show a notch on one side giving the appearance of a mitten. The stems are sometimes red and the leaves will turn red in the fall. Sometimes poison ivy will vine up into the trees. There are a number of other plants that fit this description so avoid them if you are unsure.
Poison Ivy produces Urushiol, a skin irritant that causes an itching rash (urushiol-induced contact dermatitis). Urushiol oil binds to the skin on contact, where it causes severe itching that develops into reddish colored rash and blistering.
The fluids released by itching blisters do not spread the poison. If a rash appears to be spreading, more than likely some areas received more of the poison and reacted sooner than others. The oozing blisters result from our own immune system releasing fluid through the skin. If the skin is cooled, such as washing in cold water, the vessels constrict.
Urushiol can remain active for several years, so handling dead leaves or vines can still cause a reaction. The oils can also be transmitted on an animal’s fur and can cause the rash if it comes into contact with the skin. Clothing, tools, and other objects that have been exposed to the oil should be washed to prevent further transmission..and be sure to give your dog a bath too!
One thing you should NEVER do is burn poison ivy because the oils go into the smoke and a rash can occur on the lining of the lungs, causing extreme pain and possibly fatal respiratory difficulty. If poison ivy is eaten, the digestive tract, airway, kidneys or other organs can be damaged. A poison ivy rash can last anywhere from one to four weeks, depending on severity and treatment. In rare cases, poison ivy reactions may require hospitalization.
If you think you’ve had contact with poison ivy, immediately wash those areas of the skin. Most of the oil is absorbed into the skin in the first 30 minutes. Sometimes the rash can be completely avoided by washing with plenty of cold water within the first 10 or 15 minutes. Washing with Fels Naptha soap and leaving the lather on to dry was my Grandma’s poison ivy treatment. Try not to scratch the rash, which is easier said than done. Also keep your fingernails short to keep from breaking open the blisters and spreading bacteria.
Apply wet compresses to soak the area, use Calamine lotion or antihistamines to help relieve symptoms.
Natural remedies such as the juice from Jewelweed and Chickweed can be applied to the blisters or made into a poultice or salve to alleviate itching and symptoms. Also simply mixing oatmeal, baking soda, with a little water and applying as a paste and left to dry is recommended by dermatologists for the treatment of poison ivy.
