Habitat:  Rocky exposed places and woody slopes below 1200 metres[71].

Medicinal Information: The bark is antirheumatic and febrifuge[257]. A decoction has been taken internally in the treatment of rheumatism, ague, consumption and heartburn[257]. A decoction has been used as a wash for cuts and bruises[257]. The liquid obtained from chewing the roots has been used as a salve and to prevent swelling from wounds and abrasions[257]. Berberine, universally present in rhizomes of Mahonia species, has marked antibacterial effects[218] and is used as a bitter tonic[213]. Since it is not appreciably absorbed by the body, it is used orally in the treatment of various enteric infections, especially bacillary dysentery[218]. It should not be used with Glyccyrriza species (Liquorice) because this nullifies the effects of the berberine[218]. Berberine has also shown antitumour activity[218]. The root and rootbark are best harvested in the autumn[213].
