Berberine, universally present in rhizomes of Mahonia species, has marked antibacterial effects[5] and is used as a bitter tonic[4]. Since it is not appreciably absorbed by the body, it is used orally in the treatment of various enteric infections, especially bacterial dysentery[5]. It should not be used with Glycyrrhiza species (Liquorice) because this nullifies the effects of the berberine[5]. Berberine has also shown antitumour activity[5]. The root and root bark are best harvested in the autumn[4].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[6]. It usually germinates in the spring[K]. 'Green' seed (harvested when the embryo has fully developed but before the seed case has dried) should be sown as soon as it is harvested and germinates within 6 weeks[K]. Stored seed should be sown as soon as possible in late winter or spring. 3 weeks cold stratification will improve its germination, which should take place in 3 - 6 months at 10°c. Prick out the seedlings when they are large enough to handle and grow them on in a cold frame for at least their first winter. Plant them out in late spring or early summer. Division of suckers in spring[6]. Whilst they can be placed direct into their permanent positions, better results are achieved if they are potted up and placed in a frame until established[1]. Leaf cuttings in the autumn.

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

An easily grown shrub, it thrives in any good garden soil[1] including heavy clays. Prefers a semi-shaded woodland position in a damp, slightly acid to neutral humus-rich soil[3]. Plants can tolerate temperatures down to about -10°c[3]. Plants are very tolerant of pruning and can be cut right back into old wood if they have outgrown their welcome[2]. Plants produce suckers and form gradually spreading clumps[3]. Hybridizes freely with other members of this genus.
