Background

Poison ivy (Toxicodendron radicans) is a shrub and vine. It contains a chemical that causes skin irritation and allergic reactions for many people.

Poison ivy is part of the cashew family, not the ivy family. It's used in homeopathic medicine, meaning it's given in extremely dilute doses, often so dilute that they contain little or no poison ivy. But it's not clear how it might work.

Homeopathic preparations of poison ivy are used to treat pain, rheumatoid arthritis, sprains, and itchy skin disorders, but there is no good scientific evidence to support these uses.
When taken by mouth: Poison ivy is likely unsafe. Chemicals in poison ivy can cause allergic reactions with widespread symptoms, including severe irritation of the mouth and throat, vomiting, fever, and coma.

When applied to the skin: Poison ivy is likely unsafe. Skin contact with poison ivy can cause redness, swelling, and other reactions. Wash exposed areas with soap and water within 5-10 minutes of contact to limit skin irritation.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Poison ivy is likely unsafe to take by mouth or apply to the skin while pregnant or breast-feeding. Stay on the safe side and avoid use.

Allergies: People with allergies to other substances, such as cashew, mango, and ginkgo, might also be allergic to poison ivy.
