China People's Pharmacopoeia (2000 edition) contains five kinds of medicinal Dendrobium nobile, namely Dendrobium candidum, Dendrobium candidum and Dendrobium nobile, but there are actually many kinds of folk medicinal Dendrobium nobile, and many varieties are used to extract some ingredients as pharmaceutical raw materials. Among 76 species of Dendrobium in China, nearly 40 species are medicinal. Some medicinal Dendrobium species have been exported for a long time and are very famous in Southeast Asia and some areas in Europe and America.

You can arrange them according to the active ingredients of various Dendrobium species.

I think:

1, Dendrobium candidum and Dendrobium candidum rank first, and the polysaccharide content of Dendrobium candidum in Guangnan, Yunnan is as high as 45% (it has been listed as a national geographical indication protection product).

2, Huoshan Mi Hu, Huoshan Mi Hu is more precious than Dendrobium candidum, because it is small and lovely, with little output and the highest price among Dendrobium candidum. But consumers don't have to worry about buying rice or canned food. The amount of Dendrobium candidum bought with 100 yuan has greatly exceeded the amount of Dendrobium candidum that can be bought.

3. Both Dendrobium candidum and Dendrobium candidum can be used as medicine, and their effective components are far less than Dendrobium candidum.

4. Dendrobium nobile, Dendrobium drumstick, Dendrobium candidum, Dendrobium verrucosum, Dendrobium candidum, etc. Even a laundry list is not as small as Dendrobium candidum.

Personal opinion, don't spray if you don't like it.
