Our mild Poison Ivy Relief Soap contains the juices from jewelweed, plantain, and sweet fern, along with soothing olive, coconut, and palm oils, to effectively remove the nasty urushiol (the invisible plant oil) that causes the itching, burning rash of poison ivy. If a rash does appear, the plantain/sweet fern solution in our soap could help relieve the itch. This soap has been known to be helpful after contact with brown tail moth caterpillars and other skin irritants, as well.
