Antidote Antiinflammatory Bitter Diaphoretic Diuretic Expectorant Febrifuge Odontalgic
Stimulant Tonic
The Virginia snakeroot is attracting increasing interest for its medicinal virtues and as a result is becoming uncommon in the wild. It merits consideration for cultivation in forest areas[222]. It is used in a number of proprietary medicines for treating skin, circulatory and kidney disorders[238]. The plant contains aristolochic acid which, whilst stimulating white blood cell activity and speeding the healing of wounds, is also carcinogenic and damaging to the kidneys[254]. The root is harvested in the autumn and dried for later use[238]. The root is antidote, anti-inflammatory, bitter tonic, diaphoretic, diuretic and stimulant[1, 2, 4, 21, 46, 200]. Traditionally it was chewed in minute doses or used as a weak tea to promote sweating, stimulate the appetite and promote expectoration[4, 222]. The native North Americans considered it to have analgesic properties and used an infusion internally to treat rheumatism, pain - but especially sharp pains in the breast, and as a wash for headaches[257]. This plant should be used with caution, it is irritating in large doses and can cause nausea, griping pains in the bowels etc[4, 21, 222]. It should only be used internally under the supervision of a qualified practitioner[238]. The bruised root is placed in hollow teeth for treating toothache[207]. An extract of the root can be drunk to relieve stomach pains[207]. The boiled root, or a decoction of the whole plant, can be used to treat fevers[213]. The chewed root or crushed leaves was applied to snakebites[207, 213]. This species was the most popular snakebite remedy in N. America[213]. It has also been applied externally to slow-healing wounds and in the treatment of pleurisy[238].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.
An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details
Prefers a well-drained loamy soil, rich in organic matter, in sun or semi-shade[1, 200], but succeeds in ordinary garden soil[134]. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200]. Most species in this genus have malodorous flowers that are pollinated by flies[200]. The flowers of this plant are sometimes cleistogomous[235].

Propagation
Seed - best sown in a greenhouse as soon as it is ripe in the autumn. Pre-soak stored seed for 48 hours in hand-hot water and surface sow in a greenhouse[134]. Germination usually takes place within 1 - 3 months at 20°c[134]. Stored seed germinates better if it is given 3 months cold stratification at 5°c[200]. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant out in late spring or early summer after the last expected frosts. Division in autumn[200]. Root cuttings in winter[200].
