Broomweed was widely employed medicinally by several native North American Indian tribes who used it to treat a variety of complaints[257]. It is little, if at all, used in modern herbalism. A decoction of the roots has been used in the treatment of painful urination, diarrhoea and stomach aches[257]. The roots have been placed in boiling water and the steam inhaled in the treatment of respiratory complaints[257]. The flowers are laxative[257]. A decoction of the fresh flowers has been used in the treatment of diarrhoea[257]. The leaves are cathartic, febrifuge and sedative[257]. An infusion has been used in the treatment of coughs and colds[257]. It has also been used as a bath to treat fevers and sores, including those caused by venereal diseases[257]. A poultice of the moistened leaves has been used to treat bruises, wounds, sprains, nose bleeds and insect stings[257]. A protein in the plant is reported to have anti-cancer activity[274]. A strong, black infusion of the plant has been used as a rub on rheumatic joints[257].

Cultivation details

Requires a position in full sun in a deep open well-drained soil[200]. Often found in calcareous soils in the wild[274]. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200]. Plants are sub-shrubs and may die back to the base in winter[200]. Plants have deep taproots and resent root disturbance[200]. They should be planted into their permanent positions as soon as possible. Because it is unpalatable to livestock, this plant is often an indicator of overgrazed land[274]. Plants are strongly aromatic[200].

Grow on for the first winter in a greenhouse and plant out into their permanent positions in late spring or early summer[200]. Cuttings of half-ripe wood, July/August in a frame.
