Background

Cow parsnip (Heracleum maximum) is the only member of the hogweeds that is native to North America. Like other hogweeds, cow parsnip sap can cause blisters and phytophotodermatitis. There is currently insufficient evidence available in humans to support the use of cow parsnip for any indication.
Some Native American tribes used cow parsnip to treat bruises and sores.
