Medicinal Uses

Abortifacient Antiinflammatory Antispasmodic Diaphoretic Eczema Emmenagogue Febrifuge Oxytoxic
Stimulant
Birthwort has a very long history of medicinal use, though it has been little researched scientifically and is little used by present-day herbalists[254, 268]. It is an aromatic tonic herb that stimulates the uterus, reduces inflammation, controls bacterial infections and promotes healing[238]. The juice from the stems was used to induce childbirth[268]. 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 flowering herb, with or without the root, is abortifacient, anti-inflammatory, antispasmodic, diaphoretic, emmenagogue, febrifuge, oxytocic and stimulant[7, 9, 21, 100, 200]. Another report says that the root is used on its own[238] whilst a third says that either the fresh flowering herb or the dried rootstock can be used[268]. The plant should not be used internally without experienced supervision, externally it is used in the treatment of slow-healing cuts, eczema, infected toe and finger nails etc[9]. Use with caution, internal consumption can cause damage to the kidneys and uterine bleeding[7, 9, 21]. It should not be used by pregnant women[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, 134]. Succeeds in ordinary garden soil[134]. The plant has an invasive root system[233]. Most species in this genus have malodorous flowers, often smelling like decaying flesh[245], that are pollinated by flies[200]. The insects that pollinate this plant become trapped in the hairy throat of the flower[233]. Birthwort was formerly cultivated as a medicinal plant in most of Europe[50].

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].
