Twelve images of the berberine-rich, bright yellow inner bark of Mahonia or Berberis a member of the barberry family, Berberidaceae, which is variously separated into the genus Mahonia in some botanical treatments and lumped into the larger genus, Berberis in other taxonomic treatments. There are about 70 species of Mahonia primarily found in East Asia and the Pacific Northwest in the US and adjacent Canada. Mahonia bark and root is high in the bioactive alkaloid berberine. Used by native groups for stomach problems, bleeding, tonic, eyewash, to purify the blood, etc. It has sometimes been suggested as a useful substitute for other berberine-rich plants such as goldenseal Hydrastis canadensis.
