Another report says that it is an active antitumour agent but is too toxic for clinical use[218]. Another report says that aristolochic acid has anti-cancer properties and can be used in conjunction with chemotherapy and radiotherapy and that it also increases the cellular immunity and phagocytosis function of the phagocytic cells[176].

Medicinal Uses


Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Abortifacient;  Antiinflammatory;  Antispasmodic;  Diaphoretic;  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].

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].

Be careful: A US-Croatian team confirmed that poisoned bread causes a kidney disease endemic to the Balkans - and verified that the same toxic ingredient was in herbal supplements used around the world

The Scientist, magazine of the Life Sciences Linked to a kidney disease endemic to the Balkans - Endemic Nephropathy or aristolochic acid nephropathy

This is a dangerous plant and should not be consumed, even in small amounts. Accidental inclusion with wheat harvest in eastern Europe has been implicated in hundreds of cases of kidney failure, renal cancer and death. Also linked to kidney failure/death when taken as an herbal supplement. The first class-action lawsuit in China was filed about this herb. Avoid.

I used this plant for a few months as I suffer from a severe seborrheic dermatitis. Actually this plant is the best and the cheapest option you have. I have tried before different types of shampoo recommended for this type of illness from Nizoral to most of the Ducray gamma with very little result as the eczemas were back after 2 days. I've used internally but in small quantity but at that time I didn't knew is that toxic. Now I will never use it internally but externally is a very good remedy in my case. Rodica If you read this and if you still have seeds please contact me because I'm interested on growing it. You can find me on http://www.romani-online.co.uk/ with the nick florin_mol . My name is Florin Moldovanu. Thank you.
