Ligusticum grayi is a species of flowering plant in the carrot family known by the common name Gray's licorice-root. It is native to the western United States from Montana to California, where it grows in moist, mountainous habitat, such as meadows and forest floors.^[1] It is a carrotlike, perennial herb growing from a taproot to heights between 20 and 80 centimeters.^[1] The leaves are like those of its relatives, including celery, each divided into several leaflets with pointed lobes. The inflorescence is a compound umbel of many small, white flowers. The Atsugewi used various parts of this plant for medicinal and other uses.^[2]
