Contact dermatitis from exposure to certain plants can be serious business. We’re all familiar with the dermatitis resulting from touching poison ivy but other plants can cause a reaction as well.
My son got blisters on his arm from pulling lots of English ivy from a neighbor’s lot.
Now a close friend has developed a massive case or dermatitis from pulling evergreen passionvine, Passiflora caerulea, out of her landscape. Within a day of her work, festering red splotches appeared on her skin. They did not itch like poison ivy (which was not present in her vine area) but rather burned and stung at the slightest touch. Her only relief came from Milk of Magnesia dabbed on the eruptions plus ice packs on the “hot” areas.
I can find no online citations for passionvine dermatitis but plants in the species contain many chemical compounds, both harmful and helpful.
Email me if you have had dermatitis from passionvine (or any other landscape plant).
