Material usesThere are no material uses listed for Mahonia japonica.
The seed is febrifuge and tonic. The roots and stems are antirheumatic, antitussive, depurative, expectorant and febrifuge. A decoction is used in the treatment of bone-breaking fevers, dizziness and tinnitus, backache, weak knees, dysentery and enteritis. The root and root bark are best harvested in the autumn.Berberine, universally present in rhizomes of Mahonia species, has marked antibacterial effects and is used as a bitter tonic. Since it is not appreciably absorbed by the body, it is used orally in the treatment of various enteric infections, especially bacterial dysentery. It should not be used with Glycyrrhiza species (Liquorice) because this nullifies the effects of the berberine. Berberine has also shown antitumour activity.

The fully dormant plant is hardy to about -20°c, though the young growth in spring can be damaged by late frosts. Plants are very tolerant of pruning and can be cut right back into old wood if they have outgrown their welcome. This species is closely related to M. bealei. It hybridizes freely with other members of the genus.The flowers have a delicious perfume. The form 'Hiemalis' bears larger flower spikes which are almost as strongly scented as Lily of the Valley (Convallaria majalis).
