Dendrobium is a good health food and medicinal material, which is deeply loved by people. However, due to the harsh growth conditions of Dendrobium candidum, the natural output is extremely scarce, and because of long-term over-exploitation, wild resources are on the verge of extinction. The real Dendrobium candidum is expensive. There are many so-called Dendrobium candidum in Taobao and pharmacies, which are very cheap and generally not authentic Dendrobium candidum. At present, only a few old brands such as Fulinmen and Tongrentang Dendrobium candidum can buy authentic Dendrobium candidum.
