Amomum subulatum Fruit Source & Identity
The botanical entity is Amomum subulatum Roxb., a perennial of the ginger family, Zingiberaceae, grown in the eastern Himalaya and called large, Nepal or black cardamom. The part used is the dried fruit capsule with its seeds. Leaves, rhizomes and flower spikes are not part of this black cardamom extract.
Two look-alikes cause most of the confusion. Elettaria cardamomum is green cardamom, a different genus with smaller pods and a different aroma, and Amomum tsao-ko, called caoguo, is another large Chinese pod. Smoke-drying gives black cardamom a smoky character that the green species does not have.
The essential oil of the pod is dominated by 1,8-cineole, and the seeds also carry flavonoids and phenolic compounds.
