About Indian hemp

Indian Hemp is a bushy member of the dogbane family that may grow to 5 feet tall. All parts of this plant exude a milky juice when bruised and all plant parts are considered highly toxic to humans and mammals. This plant typically grows in the wild in dry rocky or open woods, glades and prairies. Stems are fibrous and were important to Indigenous communities for making rope products.
