    Chinese medicine is the treasure of the Chinese nation, Chinese drugs is the key to the healthy development of the protection of traditional Chinese medicine industry. But due to environmental damage, the drug such as overexploitation, many traditional rare traditional Chinese medicinal materials are increasingly scarce, even endangered, needed eco-systems.
 
    Caulis dendrobii is China's traditional rare traditional Chinese medicinal materials, has the very high medicinal value and nourishing health. At present around the world have more than 1000 kinds of plants of the genus dendrobium stem, one of the most medicinal value is huoshan dendrobium stem. Huoshan dendrobium stem, according to research, medicinal origin can be traced back to the history of the third century AD, the doctors don't record ", recorded in the book: "caulis dendrobii luan valley water alongside the stone." Effect of caulis dendrobii, originated in the cold-induced febride, since all previous dynasties in the herb has a variety of caulis dendrobii, huoshan dendrobium stem are all previous dynasties herbs recorded in a most, and most detailed description. Pharmacists xue-min zhao qing dynasty's "compendium of materia medica shortage make-up" records: "fausset welcome jiangnan huoshan, shaped like a women welcome small, yellow color and the shape is not straight, has the ball, he natives to generation of tea tea."

    Huoshan dendrobium stem, however, due to the natural reproduction rate is low, high medicinal value, as early as in ancient times due to the "north-south prevalence of" difficult to seek. Is also precisely because "there is not to give" falsify emerged. Today, caulis dendrobii still thrives, but already scarce huoshan dendrobium stem, now more difficult to find its trace, fake and inferior species become wide.
 
    Huoshan dendrobium stem, modern pharmacology study shows that the morphological characteristics, genetic structure, pharmacological activity and chemical composition are different from other caulis dendrobii, is the most medicinal efficacy of many types of caulis dendrobii varieties. It contains caulis dendrobii polysaccharide, a variety of alkaloids, 18 kinds of amino acids and proteins, more than 10 kinds of trace elements, regulate the body's immunity, antioxidation, antitumor, reduce blood sugar, and so on, to treat diabetes, gastrointestinal disease, cataract, arthritis, buerger's disease, chronic pharyngitis, allergic dermatitis has good curative effect, etc. And, in huoshan dendrobium stem, the content of effective component is much higher than other caulis dendrobii. But huoshan dendrobium stem short, plant growth environment, huoshan county only 15 villages and towns regional natural environment is suitable for growth. Therefore, the current market sales of huoshan dendrobium stem often a busman, much by other types of caulis dendrobii, even there are a lot of fake and inferior products.
 
    , the survey found that is easily confused with huoshan dendrobium stem on the market there are three main kinds of caulis dendrobii, many businesses in huoshan local iron caulis dendrobii, thin stems, caulis dendrobii and heavy labial caulis dendrobii processed, instead of huoshan dendrobium stem. Tin caulis dendrobii is also called "black day" grass and plant bulky, alternaria alternata in yunnan, zhejiang area, is a kind of very good quality drug materials. But now also for resources gradually dry up, often for other types of caulis dendrobii has been replaced. Fibrous caulis dendrobii is also called copper caulis dendrobii, distribution range huoshan dendrobium stem and tin caulis dendrobii wider. Fibrous caulis dendrobii huoshan dendrobium stem, although less valuable, but it is keeping in good health effect, production is more, the price also is moderate, often used as a substitute for huoshan dendrobium stem. Heavy labial caulis dendrobii, also known as net vein lips caulis dendrobii, "chicken feet". According to Shanghai may experience the medicinal materials compilation of data collecting, said heavy labial caulis dendrobii advocate in guangxi, form a thick, green with purple color, taste bitter, SAP viscosity is poor, so that the poor quality.
 
    In addition, easily confused with huoshan dendrobium stem and yellow (flower), caulis dendrobii, caulis dendrobii, beautiful marble welcome, fine we examined welcome, curved stem caulis dendrobii, caulis dendrobii, henan, guangdong caulis dendrobii, Nile caulis dendrobii, etc. But these caulis dendrobii both in rare degree and medicinal efficacy, less huoshan dendrobium stem.
 
    In recent years, the national related departments have begun to protection work of huoshan dendrobium stem, huoshan county government also contribute to the huoshan dendrobium stem planting base gives support and reward. But huoshan dendrobium stem resources saving, protection and development still needs to strengthen, should use the modern biological propagation technology expand the scale of huoshan dendrobium stem cultivation, huoshan dendrobium stem, at the same time, strengthen product development and market promotion, huoshan dendrobium stem, realize industrialization.
