Dendrobium officinale Kimura & Migo is an orchid native from southern China to northern Vietnam, southern Japan and Taiwan (Plants of the World Online, Kew). In Chinese it is 铁皮石斛.
Older literature and some trade documents use the name Dendrobium catenatum. World Flora Online accepts D. officinale and lists D. catenatum as one of its synonyms (World Flora Online). Our documents use Dendrobium officinale.
All orchids are listed in CITES Appendix II. Its annotation #4 exempts seeds, pollen, flasked seedlings, cut flowers of artificially propagated plants and a few named products, but not dried stems, powder or juice of Dendrobium (CITES Appendices, valid from 25 November 2023).
So each shipment of these products leaves China with a CITES export permit. Some destination countries also require an import permit; we check this with you before shipping.
Plants are attached to living trees and rock faces under the forest canopy and grown without greenhouses, close to the conditions the species grows in naturally.
Every batch ships with a certificate of analysis (COA); the testing laboratory is named on each certificate. These are the parameters on each COA; limits are agreed per contract.
| Product | Parameter | Specification limit | Test method / lab |
|---|---|---|---|
| All products | Species identity (morphology or DNA) | Agreed per contract | Named on each COA |
| All products | Polysaccharide content | Agreed per contract | Named on each COA |
| Dried stems and powder | Moisture | Agreed per contract | Named on each COA |
| Dried stems and powder | Total ash | Agreed per contract | Named on each COA |
| All products | Heavy metals (Pb, As, Cd, Hg) | Agreed per contract | Named on each COA |
| All products | Pesticide residues | Agreed per contract | Named on each COA |
| Powder and juice | Total plate count, yeast and mould | Agreed per contract | Named on each COA |
| Juice | E. coli and Salmonella | Agreed per contract | Named on each COA |
Ask for the latest COA for your product with your enquiry. Batch number, test date and lab are on every certificate.
A certificate is listed here only with its number, so that buyers can check it. Ask which documents are available for your product and destination market.
We supply dried stems, powder and juice in bulk for your own processing or brand, and can pack retail units with your label. Product names and descriptions follow the food rules of your market, and we do not supply health claims for labels.

CAM Photosynthesis, VPD Water Control, Growth-Differentiation Balance and Nocturnal Core-Body-Temperature Regulation
What plant physiology and physics say about growing this orchid: night-time carbon fixation, vapour-pressure deficit and how moving air keeps leaves dry without sprays, a carbon budget that weighs yield against polysaccharide, bark substrates and fertiliser salts, the rheology of a fresh-stem decoction, and what a warm drink can and cannot do to body temperature at night, with a four-step weekly check for growers and a pre-registered sleep trial.
