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.
Expectorant Homeopathy Sedative Skin
The dried leaves and flowering tops are antiasthmatic, expectorant and sedative[4]. The principal use of this herb is in the treatment of bronchial catarrh, especially when there is an asthmatic tendency[4]. The active principle is excreted from the kidneys, and this sometimes produces signs of renal irritation[4]. The plant has been used in the treatment of itching skin eruptions caused by contact with poison oak (Rhus spp.)[257]. A homeopathic remedy is prepared from the leaves and flowering stems[4].

Cultivation details
Succeeds in any well-drained soil in full sun[200]. Does well on dry sandy banks and in poor soils[200]. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200]. There is some confusion over the correct name for this species. The report on medicinal uses in [4] relates to G. cuniefolia, a name that has been used by two authors. G. cuniefolia. non Nutt. is said to be a synonym of G. humilis and so the entry has been made here.
