Antiemetic Astringent Carminative Depurative Diuretic Laxative
The root is astringent, carminative, depurative, diuretic, purgative and tonic[51, 91, 240]. Small doses act as an astringent tonic to the digestive system, whilst larger doses act as a mild laxative[232]. The flowering stem is used in Tibetan medicine, it is said to have a sour taste and a heating potency[241]. It is antiemetic, diuretic and laxative[241]. It is used in the treatment of swellings and fullness of the abdomen as well as to rid the body of retained fluids[241].

Cultivation details
Prefers a deep, fertile, moderately heavy, humus rich, moisture retentive, well-drained soil in sun or semi-shade. Grows well in heavy clay soils. A very ornamental plant[1], it is hardy to about -15°c[200]. Plants have proved very difficult to grow in cultivation in Britain[187]. Plants in this genus seem to be immune to the predations of rabbits[233]. Hybridizes freely with other members of this genus[200].

Plant Propagation
Seed - best sown in autumn in a shaded cold frame[200]. The seed can also be sown in spring in a cold frame. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse or cold frame for their first winter, planting them out in the spring. Division in early spring or autumn[1, 111]. Divide up the rootstock with a sharp spade or knife, making sure that there is at least one growth bud on each division. Larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.
