Medicinal Uses

Analgesic Contraceptive Disinfectant Febrifuge Poultice Salve Although a very poisonous plant, California false hellebore was often employed medicinally by a number of native North American Indian tribes who used it mainly as an external application to treat wounds etc[257]. It also had quite a reputation as a contraceptive[257]. It is little, if at all, used in modern herbalism. Any use of this plant, especially internal use, should be carried out with great care and preferably only under the supervision of a qualified practitioner. The root is analgesic, disinfectant and febrifuge[257]. A decoction has been used in the treatment of venereal disease[257]. The roots have been grated then chewed and the juice swallowed as a treatment for colds[257]. A poultice of the mashed raw root has been used as a treatment for rheumatism, boils, sores, cuts, swellings and burns[257]. The dried and ground up root has been used as a dressing on bruises and sores[257]. A poultice of the chewed root has been applied to rattlesnake bites to draw out the poison[257]. The powdered root has been rubbed on the face to allay the pain of toothache[257]. A decoction of the root has been taken orally by both men and women as a contraceptive[61, 257]. A dose of one teaspoon of this decoction three times a day for three weeks is said to ensure permanent sterility in women[207, 254].

Known Hazards

All parts of the plant are highly poisonous[155, 200]. The flowers are poisonous to insects, including bees[155].
