Common Name: Poison Ivy
Latin Name: Toxicodendron radicans
What I know about this plant: It produces the evil urushiol chemical that I'm seriously allergic to! Grows on woody vines that can get sapling thick as they grow parasitically up a tree and appear sort of hairy; leaves grow in threes and turn a lovely red in fall before dropping; whitish berry clusters form in late summer/early fall and are favored by small birds
Photo: The very mature plant on the nearly dead pine outside my kitchen window. I learned about the evil of this plant spring 2007 when I was pregnant with Elias and had urushiol-induced dermatitis covering about 80% of my body after doing some spring cleaning in the yard. I had been pulling the vines down out of the trees, totally unaware of what they were, and the chemical even got into some scratches I had on my arms. I was in agony for weeks, and it was all over me! The midwife offered me some meds, but I just took half doses of Benadryl and slathered on Triamcinolone Acetonide lotion when the itching got really bad. The Benadryl pretty much dried up my milk for William. :( He wasn't phased by it, though, and is still nursing. Just recently, I brushed a finger against a leaf growing in our yard waste pile, and within 10 minutes I had a blister forming from the contact. I went inside and scrubbed my hands with hot water and put some of the TCA lotion on it and I was fine. Scared me, though.
