Antiasthmatic Antiseptic Antitussive Cancer Dysentery Expectorant Sedative
The fruit and its capsule are antiasthmatic, antiseptic, antitussive and expectorant. A decoction of the fruit is used in the treatment of cancer, coughs, inflammation of the respiratory organs, haemorrhoids and hypertension[176, 218, 279]. It is also used to resolve phlegm and lower blood pressure[176]. It has an antibacterial action, effective against Staphylococcus aureus, Pneumococci, bacillus dysentericae etc[176]. The root contains aristolochic acid. This has anti-cancer properties and can be used in conjunction with chemotherapy and radiotherapy[176]. Aristolochic acid can also be used in the treatment of acute and serious infections such as TB, hepatitis, liver cirrhosis and infantile pneumonia[176]. It also increases the cellular immunity and phagocytosis function of the phagocytic cells[176]. Aristolochic acid is said to be too toxic for clinical use[218]. The root is used as a purgative in the treatment of rabies and also has sedative properties[218].

Cultivation details
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus. Prefers a well-drained loamy soil, rich in organic matter, in sun or semi-shade[134, 200]. Succeeds in ordinary garden soil[134]. Most species in this genus have malodorous flowers that are pollinated by flies[200].

Plant 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].
