Medicinal Uses
Disclaimer
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].
Other Uses
Insecticide.
The dried and powdered root is used as an insecticide and a
parasiticide[172]. It is also effective against caterpillars and mammals so
great caution is advised[1, 19, 20].
Cultivation details
Requires a deep fertile moisture retentive humus-rich soil[200].
Succeeds in full sun if the soil does not dry out but prefers a position in
semi-shade[200]. Dislikes dry soils[42]. Grows best in a cool woodland garden
or a north facing border[42].
Members of this genus are rarely if ever troubled by browsing deer[233].
Plants are long-lived and can be left in the same position for years without
attention[233].
Propagation
Unless stored in damp sand at around 4° c the seed has a short
viability[200]. Where possible it is best to sow the seed in a lightly shaded
position in the greenhouse as soon as it is ripe[200]. Stored seed needs to
be stratified but can be very slow to germinate. Germination can be erratic
even for seed sown when it was fresh, it usually takes place within 3 - 12
months at 15° c but can be much longer[200]. The plant produces just one
seedleaf in its first year, this forms an over-wintering bulb. It takes up to
10 years for the plant to reach maturity[200]. Sow the seed thinly so there
is no need to thin or transplant them, and grow the seedlings on undisturbed
in the pot for their first two years of growth. Apply a liquid feed at
intervals through the growing season to ensure the plants do not become
nutrient deficient. At the end of the second year plant out the dormant
plants into individual pots and grow them on in light shade in the greenhouse
for a further year or two before planting them out into their permanent
positions in late spring or early summer.
Division in March/April or in October. Establish the plants in pots in a
shaded frame before planting them out[200]. Division is best carried out in
the autumn because the plants come into growth very early in the spring[233].
Root cuttings, 6mm long with a bud, rooted in a sandy soil in a cold
frame[200].
