Dendrobium officinale Stem Identity & Plant Part
The botanical entity is Dendrobium officinale Kimura & Migo, an epiphytic orchid of the family Orchidaceae. The part used is the dried stem, which is slender, jointed and covered by a thin outer skin. Leaves, flowers and roots are not added to this dendrobium extract.
Dendrobium is a very large genus, and species such as Dendrobium nobile carry different alkaloid profiles and appearance. A specification that gives only the genus name cannot identify the stem. D. officinale stems contain mucilaginous glucomannan-type polysaccharides, together with bibenzyls and small amounts of alkaloids, so a hot-water extract turns gummy and viscous as it concentrates.
