Plagued by poison ivy allergy? It might be possible to coax the body to build up immunity to poison ivy.
That news comes from researchers including Mary Morris, MD, of Allergy Associates of La Crosse in La Crosse, Wis.
They studied 115 people with a history of severe skin reactions to poison ivy who were treated at their clinic over the past 15 years.
The treatment was a small amount of poison ivy extract placed under the tongue. The goal was to train the body's immune system not to overreact to poison ivy.
The patients took skin tests to see if the treatment helped.
