Medicinal uses(Warning!)

This species has a history of herbal use in China going back over 2,000 years and modern clinical tests have demonstrated its efficacy[5][4]. It is widely used there in patent remedies and is also made into cough tablets[4]. The root contains saponins and is anthelmintic, antiasthmatic, anticholesterolemic, antiphlogistic, antitussive, astringent, carminative, expectorant, haemolytic, hypoglycaemic, sedative, stomachic, tonic and vermifuge. It lowers blood sugar and cholesterol levels in the liver and inhibits the release of histamine[1][6][7][8][9][5][4][10]. It is used internally in the treatment of coughs with profuse phlegm, colds, bronchitis, pleurisy, pulmonary abscesses and throat infections[8][4]. It is also used to treat hypertension and diabetes in Korea[10]. The root of plants 2 - 3 years old are harvested in the spring or autumn, peeled and used fresh or dried[4].

Propagation

Seed - sow spring in a cold frame[11]. Free and quick germination[K]. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in the winter when the plants are dormant[238, K]. Basal cuttings of non-flowering shoots in spring, preferably with a piece of root attached[12]. Harvest the shoots with plenty of underground stem when they are about 8 - 10cm above the ground. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.
