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.

Antibacterial;  Diuretic;  Purgative;  Vasodilator.

Da Ji is classified as a toxic herb in Chinese medicine and so is only prescribed for relatively serious diseases[254]. It is considered to be one of the 50 fundamental herbs[218] and is used as a cathartic to purge excess fluids in conditions such as pleurisy and ascites and for the treatment of kidney problems, especially nephritis[254]. Research has shown that it is therapeutically useful in the treatment of ascites and nephritis, but it does produce significant side-effects[254]. It should only be used under the supervision of a qualified herbalist[254]. The root is antibacterial, diuretic, emetic, emmenagogue, purgative and vasodilator[176, 218, 238]. It is used in the treatment of oedema, fullness of the chest, sticky sputum, epilepsy, carbuncle and tubercle[176]. When used in conjunction with liquorice (Glycyrrhiza species) the diuretic and purgative actions are inhibited[176]. Another report says that the plant is incompatible with liquorice because it neutralizes their medicinal effects[254]. Externally, it is applied to inflamed sores to reduce swelling[254].

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 most parts of this country. It is a polymorphic species[58]. The following notes are based on the general needs of the genus. Prefers a light well-drained moderately rich loam in an open position[200]. Succeeds in dry soils[1]. Hybridizes with other members of this genus[200]. The ripe seed is released explosively from the seed capsules[200]. Members of this genus are rarely if ever troubled by browsing deer or rabbits[233]. This genus has been singled out as a potential source of latex (for making rubber) for the temperate zone, although no individual species has been singled out[141].
