There are more than 1,500 species of Dendrobium in the world, and there are about 76 species in my country. Dendrobium officinale is a precious medicinal material, and the price is not cheap. The one prescribed by the hospital is Dendrobium officinale, which is the most precious species with the highest medicinal value among dendrobiums. However, the medicinal effects of ordinary types of dendrobium are quite different. For example, there are Dendrobium officinale, Dendrobium officinale Huoshan, Dendrobium officinale, Dendrobium officinale, Dendrobium officinale, etc. Dendrobium officinale has high sugar content and has a strong effect of nourishing and nourishing yin; Dendrobium officinale has been used exclusively by the royal family in history, and the emperors wanted to live forever. And use Huoshan dendrobium to refine the longevity pill.
Dendrobium officinale has the highest medicinal value among dendrobiums. There are many types of Dendrobium officinale, but you must choose the right one! Dendrobium nobile and Dendrobium purpurea are definitely not acceptable.
Especially Dendrobium, which has basically no curative effect.
The best is the red-stem Dendrobium officinale, especially the one produced in Wenshan, Yunnan.
Whether Dendrobium is good or not depends mainly on the place of origin~~The plateau area in Yunnan, especially Wenshan, is the origin of Dendrobium officinale. The representative producing areas are Maguan Gulinqing and Guangnan. In some places, varieties with red stems and soft legs are planted, but the climate is not right and Dendrobium officinale has mutated and looks like chopsticks, so the medicinal effect will definitely be different. The polysaccharide content of green stems is not as good as that of red stems. This is easier to identify because the colors are different. But Dendrobium is also reddish, so the way to identify it is to look at the fresh strips. The nodes of Dendrobium are very long and the stems are thin. The stems of Dendrobium can grow up to 60-70 centimeters long! The longest length of red stem Dendrobium candidum is about 30 centimeters, and most of them are within 20 centimeters. The stems The pole is fat and the joints are short.
The best dendrobium is Dendrobium huoshanensis and Dendrobium candidum. The price of Huoshan is ridiculously expensive, and its medicinal value is not better than Dendrobium officinale, but it is rare and expensive, so I suggest you buy Dendrobium officinale. Iron sheets are divided into hard feet and soft feet. Soft feet are better than hard feet. There is not much difference between the red pole and the green pole. The person upstairs must be making the red pole. In fact, the main reason is that the nodes are short, the stem is 20-30 cm, and the ones that taste sticky are treasures.
As for purple bark, copper bark, aquatic plants, etc., they have little medicinal value, while ball flowers, spring dendrobium, and drumstick dendrobium are all ornamental dendrobium.
