Huang Qi is commonly used in Chinese herbalism, where it is considered to be one of the 50 fundamental herbs. The root is a sweet tonic herb that stimulates the immune system and many organs of the body, whilst lowering blood pressure and blood sugar levels. It is particularly suited to young, physically active people, increasing stamina and endurance and improving resistance to the cold - indeed for younger people it is perhaps superior to ginseng in this respect. Huang Qi is used especially for treatment of the kidneys and also to avoid senility. The plant is often used in conjuction with other herbs such as Atractylodes macrocephala and Ledebouriella seseloides.

The root is adaptogen, antipyretic, diuretic, tonic and vasodilator. It is used in the treatment of cancer, prolapse of the uterus or anus, abcesses and chronic ulcers, chronic nephritis with oedema and proteinuria. Recent research in the West has shown that the root can restore normal immune function in cancer patients. Patients undergoing chemotherapy or radiotherapy recover faster and live longer if given Huang Qi concurrently. The root of 4 year old plants is harvested in the autumn and dried for later use.

The plant is antipyretic, diuretic, pectoral and tonic. Extracts of the plant are bactericidal, hypoglycaemic and hypotensive. Cardiotonic, vasodilator.

Known Hazards: Many members of this genus contain toxic glycosides. All species with edible seedpods can be distinguished by their fleshy round or oval seedpod that looks somewhat like a greengage. A number of species can also accumulate toxic levels of selenium when grown in soils that are relatively rich in that element.
