African yellowwood — Enantia chlorantha, awopa or dokita igbo ('the Igbo doctor') — is a yellow-barked West African tree used for malaria, jaundice, fever, and infection, rich in berberine-class alkaloids.
Its berberine-class chemistry connects directly to the metabolic-syndrome and diabetes crisis in Black America — the same alkaloid family people now buy as berberine supplements grows in this West African bark, an ancestral source of the molecule.
The bright yellow bark of Enantia chlorantha is colored by protoberberine alkaloids — palmatine, columbamine, jatrorrhizine — closely related to berberine. These drive documented antimalarial, antimicrobial, antipyretic, hepatoprotective, and antihyperglycemic activity, validating its traditional use for malaria, jaundice, liver complaints, fever, and wounds. As a berberine-class plant, it shares the metabolic and blood-sugar-lowering relevance that has made berberine a major natural agent for diabetes and metabolic syndrome — central concerns for Black Americans.
Yellow bark is decocted into a bitter yellow tea for malaria, jaundice, and fever, or soaked into bitters. The bark's vivid yellow has also made it a traditional dye. Small measured doses.
