Western Native Americans (Blackfeet, Paiute, Shoshone, Thompson, and Washoe) used this species as an antirheumatic, poison, contraceptive, and emetic, as well as a skin, respiratory, blood, cold, snake bite, throat, and toothache aid (D. E. Moerman 1986).

Veratrum californicum (California corn lily, white or California false hellebore) is an extremely poisonous plant[1] native to western North America, including the Sierra Nevada and Rocky Mountains, as far north as Washington and as far south as Durango; depending on latitude, it grows from near sea level to as high as 11,000 feet.[2][3] It grows 1 to 2 meters tall, with an erect, unbranched, heavily leafy stem resembling a cornstalk.[4] It prefers quite moist soil, and can cover large areas in dense stands near streams or in wet meadows. Many inch-wide flowers cluster along the often-branched top of the stout stem; they have 6 white tepals, a green center, 6 stamens, and a 3-branched pistil (see image below). The buds are tight green spheres. The heavily veined, bright green leaves can be more than a foot long.[3]
Veratrum californicum displays mast seeding; populations bloom and seed little in most years, but in occasional years bloom and seed heavily in synchrony.[5] The species usually blooms during midsummer from July to August.[6]
It is a source of jervine, muldamine and cyclopamine, teratogens which can cause prolonged gestation associated with birth defects[7] such as holoprosencephaly and cyclopia in animals such as sheep,[1] horses, and other mammals that graze upon it. These substances inhibit the hedgehog signaling pathway.[8]

Varieties Veratrum californicum var. californicum – from Washington to Durango Veratrum californicum var. caudatum (A.Heller) C.L.Hitchc. – Idaho, Washington, Oregon, N CaliforniaVeratrum californicum est une espèce de plantes de la famille des Liliaceae selon la classification classique, ou de celle des Melanthiaceae selon la classification phylogénétique.
Elle est originaire des États-Unis.
Elle possède des alcaloïdes tels que la cyclopamine et la jervine. La cyclopamine inhibe et bloque la capacité de renouvellement de cellules souches cancéreuses. Elle est responsable de la cyclopie chez les agneaux[1].
