    The root is a pungent, very bitter, cooling herb that controls bacterial and viral infections, relaxes spasms, lowers fevers and stimulates the circulation[238]. It is locally analgesic and anaesthetic[238] and is used in Chinese medicine as a general panacea with alterative, ophthalmic and pectoral activity[178]. The root contains several compounds that are effective in inhibiting various bacteria and they are a safe and effective treatment for many ailments, such as some forms of dysentery, that are caused by bacteria[218].

Cultivation & Habitat

Seed – best sown in a greenhouse as soon as it is ripe in an ericaceous compost[164]. Seal the pot in a polythene bag until germination takes place, which is usually within 1 – 6 months at 10¡c[164]. Stored seed should be sown as early in the year as possible. Four weeks cold stratification may be beneficial[164]. Prick out the seedlings into individual pots when they are large enough to handle and grow on in a shady part of the greenhouse for at least their first winter. Plant them out in mid-autumn or in spring. Division in spring[200].
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. It is cultivated as a medicinal plant in China[178]. The following notes are based on the general needs of the genus. Succeeds in a light moist humus-rich slightly acidic soil with a northerly aspect or light shade[1, 200].
