 【Predecessors release medicine】
 "Compendium of Materia Medica" says: Dendrobium officinale, sweet can soothe the spleen, salty can benefit the kidney, so it has many benefits for water and soil. But its gas is slow, and it has no quick effect. The ancients used it as a substitute for tea, which was very refreshing.
 "Compendium of Materia Medica": There are two kinds of Dendrobium, both of which are weak. The round and thin ones with solid flesh have a light and sweet taste, and their strength is particularly weak. "Compendium of Materia Medica" says that the round and thin ones are the best, and that they can strengthen the essence and yin, strengthen the tendons and replenish the deficiency, strengthen the feet and knees, drive away cold numbness, relieve palpitations, and calm the mind. However, this thing has the weakest nature and taste, so how can it nourish so much? Only the flat and loose ones, which are shaped like hairpins, have a bitter taste and are used to remove the fire of the spleen and stomach, remove? Miscellaneous good hunger and heat in the camp, its nature is light, clear and gentle, and it has the magic of calm decomposition, so it can reduce fire, nourish yin, eliminate restlessness, clear the lungs and lower qi, and also stop thirst and hot sweat. However, various scholars say that it thickens the intestines and stomach, strengthens the yang channel, and warms the water organs. How can it be done by its bitter and cool nature and taste? It is necessary to distinguish.
 "Pharmaceutical Chemistry": Dendrobium has a light and clear smell, which is in line with the nature of the lungs. It is cool and clear in nature, and is suitable for the lungs. The lungs are delicate organs, and this is the best match. It is mainly used to treat long-term lung deficiency, persistent cough, pathogenic heat and prickly heat, and superficial heat. Its cleansing function is not limited to this. The lungs exhale, and the kidneys take in qi. The mother and child are mutually beneficial. If the lung qi is clear, the true qi will be strong, and the qi will flow downward to produce kidney water, strengthen yin and benefit essence. Moreover, the momentum of the upper jiao can make the lung qi go down in a tortuous way without the disadvantages of bitter cold sinking.
 "Compendium of Materia Medica" states: Dendrobium can enter the spleen to remove deficiency heat, and enter the kidney to astringe the vital energy. However, it is thin and has no juice, and its taste is bland and difficult to release. Unless it is boiled for a long time, its smell cannot be released, so it can only be used in mild medicine to treat deficiency heat. Although it has a tonic effect, it can only be used according to the severity of the disease.
 "Compendium of Materia Medica" says: Dendrobium is a kidney medicine, a lung medicine, and a stomach medicine. The two words "strengthening yin" in "Ben Jing" are enough to cover the whole amount. The so-called yin is neither cold nor warm. It is cold when used for warming and warming, and warm when used for colding. "Bie Lu" expels skin evil heat and prickly heat, which is cold when warm; it treats pain in the feet and knees, coldness, numbness and weakness, which is warm when cold. It must be beyond the two aspects of "Ben Jing" in removing numbness and replenishing deficiency. Generally speaking, if the symptoms are exactly suitable for Dendrobium, it must benefit from both removing numbness and replenishing deficiency. If it is used exclusively for removing numbness and replenishing deficiency, then the shortcomings should be abandoned and the advantages should be taken, and the preparation method should be reasonable.
 Xu Jiuren: Dendrobium can clear the stomach and produce fluid, and is most suitable for people with deficiency and heat in the stomach and kidney. The lung and stomach are the places where warm evil will definitely invade. Heat stagnates and burns the fluid, and gastric fluid is easily robbed. If you want to clear the stomach and save the fluid, you must use the sweet, nourishing and light Dendrobium. However, there are some cases that cannot be treated with Dendrobium alone. If the warm evil lasts for a long time, injures the lower part of the body, and robs and burns the true yin, then Jutong Wu has the Sanjia Fumai, Daxiao Dingfengzhu and other methods, which were originally designed to save the true yin. Dendrobium is too frivolous. Because the true yin is not the same as the gas and liquid. To save the true yin, it should be thick, and to save the gas and liquid, it should be light. If you use thick to save the gas and liquid, it will turn nourishing and dry, and the evil will be more serious. To save the true yin with light, it will be like a drop in the bucket, and it will definitely not work. However, there are some cases where Dendrobium should not be used excessively. For example, if the dampness and heat have not yet turned into dryness, and the patient often has dry mouth and wants to rinse his mouth, greasy tongue coating and dry skin, then spicy and light medicine should be used. If Dendrobium is used incorrectly, the tongue coating will turn black and dry, the dampness will be blocked and the heat will evaporate, and the patient may gradually become comatose. This is something that must be carefully examined.
