Here is a little something everyone may be interested in seeing....
Q: During a break in the winter weather, we decided to clear out our poison ivy growth while it was still dormant. Much to our surprise, every one of us came down with the classic symptoms of poison ivy contact rash, blisters, swelling, burning, itching you name it! I thought that we would be safe in handling this blasted vine during the dead of winter with our clothes, gloves and boots to protect us, plus the lack of foliage. Can you tell me anything about this plant? How is it picked up during the winter? How were we able to get it essentially all over our bodies almost as if we ran naked through the plants? Any assistance would be appreciated! (Wahpeton, N.D.)
A: Another painful lesson learned the hard way! Poison ivy has a toxic oil or resin produced in all parts of the plant actively growing, dormant, or dead. I assume you didn't burn the plants, as that would have put everyone in the hospital.
The toxin gets on anything it touches clothes, pruning shears, shovels and it sets up in the skin within 15 minutes of making contact. I suspect that the normal caution was down because of winter conditions, and everyone made bare skin contact with the tools, gloves and boots. As for the other body parts so affected, sawdust must have worked its way to those areas. Those clothes are considered contaminated and should be washed separately with Fels Naptha soap and rinsed completely in hot water. Obviously everyone involved was quite sensitive to the plant's toxic resin. It used to be that I could handle the plant bare-handed and never suffer the consequences. I was bragging about this minor feat one day to a group of folks who happened to have a dermatologist among them. I was promptly scolded as being a foolish show-off and told that my immunity would be "used up" some day, and that I would suffer terrible symptoms. Since then, I have kept my hands very carefully to myself around any poison ivy.
