A tall member of the carrot family found at damp edges and riverbanks, woolly cow parsnip was known to many Indigenous peoples of North America, who drew from it a remedy with varied uses.

Precautions

Before you use it

Beware of possible confusion with toxic members of the carrot family (poison hemlock, giant hogweed): certain identification by a knowledgeable person is essential before any harvesting. The sap of woolly cow parsnip can cause skin photosensitization (burns, spots) after contact followed by sun exposure; handle with gloves. Internal use discouraged without the advice of a health professional, particularly for pregnant or breastfeeding women, children, and if undergoing medical treatment. Do not exceed an occasional, traditional use; avoid any prolonged self-medication.
