 【Predecessors release medicine】
 "Tangye Bencao": "Cyperus rotundus is a medicine for replenishing the qi in the blood . It is used in the prescription to treat metrorrhagia, which is to replenish qi and stop bleeding. It can also dissolve blood clots, which is to remove the old. It can be used with croton to treat diarrhea and constipation. I agree."
 Wang Haogu: "Cyperus rotundus must be used for any cases of qi stagnation and blood stasis. Stir-frying it until black can stop bleeding and treat metrorrhagia. Using it more often can also help to move qi."
 "Compendium of Materia Medica" states: "Cyperus rotundus must be soaked in children's urine. It must be used in all blood and qi medicines to lead the qi to produce blood. This is the meaning of Yang giving birth to Yin."
 Zhu Zhenheng: "In the Materia Medica, there is no mention of tonifying effect on Cyperus rotundus, but the prescription experts say that it is beneficial to the elderly. The meaning is there, and it is probably that there is a tonifying effect in the practice."
 "Compendium of Materia Medica": "The aroma of Cyperus rotundus is flat but not cold, fragrant and can penetrate. Its taste is mostly pungent and can disperse, slightly bitter and can descend, slightly sweet and can harmonize. When raw, it goes up to the chest and diaphragm and reaches the skin. When cooked, it goes down to the liver and kidney and reaches the waist and feet. If it is fried until black, it can stop bleeding. If it is fried with Tongman, it can enter the blood and replenish deficiency. If it is fried with salt water, it can enter the blood and moisten dryness. If it is fried with green salt, it can replenish kidney qi. If it is fried with wine, it can move the meridians. If it is fried with vinegar, it can eliminate accumulation. If it is fried with ginger juice, it can resolve phlegm. If it is fried with ginseng and shu, it can replenish qi. If it is fried with gui and di hu, it can replenish blood. If it is fried with costus root, it can replenish qi. It can regulate qi and invigorate the middle. With sandalwood, it can regulate qi and invigorate the spleen. With agarwood, it can raise and lower all qi. With angelica and atractylodes, it can relieve all depression. With gardenia and coptis, it can reduce fire and heat. With poria, it can benefit the heart and kidney. With fennel and psoralea corylifolia, it can guide qi back to its origin. With magnolia bark and pinellia, it can resolve obstruction and dissipate swelling. With perilla and scallion, it can dissipate depressed qi. With three-edged atractylodes and curcuma, it can eliminate lumps. With mugwort, it can treat blood and qi and warm the uterus. It is the general manager of qi diseases and the commander of gynecology . Feixiazi Han Yu said that cyperus can promote the old and bring in the new. Therefore, all books say that it can benefit Qi, but the popular saying that it can consume Qi and is suitable for women but not for men is wrong. Women are controlled by blood, so if Qi is flowing, there will be no disease; the elderly have depleted essence and blood stasis, and only Qi is their support; children's body will become stronger as their Qi is replenished. In general, diseases are caused by stagnant Qi and fatigue, so Xiangfu is the main medicine for Qi, which is rarely known in the world. Assisted by ginseng, Astragalus, and licorice, it can cure weakness and timidity very quickly. When he was traveling outside the palace, he used Huanghe Dan to treat all kinds of diseases and Qingnang Pills to treat women . He used them as needed and they always had a small effect. People are always looking for it, so users should think about the meaning outside the law. The recipe for Huanghedan uses one catty of Cyperus rotundus and half a catty of Coptis chinensis, wash and dry them into powder, and make them into pills the size of walnuts with water paste. If it is an external infection, take it with onion and ginger soup, internal injury with rice drink, qi disease with fragrant soup, blood disease with wine, phlegm disease with ginger soup, fire disease with white soup, and the rest can be deduced by analogy. Qingnang Pills, the recipe uses one catty of slightly fried Cyperus rotundus and five liang and three qian of slightly roasted Wuyao, grind them into powder, boil water and vinegar into flour paste to make pills. Use it according to the symptoms, such as taking it with tea for headache, taking it with ginger soup for phlegm and qi, and taking it with wine for blood disease .
 "Compendium of Materia Medica" states: "Sedge root can cure women's metrorrhagia, leukorrhea and irregular menstruation. It can descend qi, regulate qi, disperse knots and regulate stagnation. Blood does not flow by itself, but follows qi. If qi is reversed and stagnant, blood will also coagulate and stagnate. If qi is smooth, blood will also follow and flow smoothly. This is why women with metrorrhagia, leukorrhea and irregular menstruation need it. However, it must be supplemented with blood-enriching and blood-cooling drugs. For those with qi deficiency, it can be effective if qi-tonifying drugs are also used."
 "Compendium of Materia Medica" states: "Xiangfu is mainly used to treat various symptoms. It should be carefully considered as a disease of qi in the blood. It is to the point and not the same as other flavors that treat qi. ... Therefore, diseases caused by the pericardium in the upper part of the body, such as depression caused by the seven emotions, can be relieved because the pericardium governs blood; diseases caused by the spleen and stomach in the middle part of the body, such as cholera vomiting and food accumulation, phlegm and fullness, can be relieved because the stomach produces blood and the spleen governs blood; diseases caused by the liver and kidney in the lower part of the body, such as bladder and hypochondria, such as bleeding, hematuria, and women's metrorrhagia, leucorrhea, and irregular menstruation, are also caused by the stomach and spleen as the origin of blood, the liver as the organ that consolidates blood, and the kidney as the sea of blood. ... This flavor promotes qi in the blood, so that blood is born in harmony. When blood is born in harmony, qi has something to rely on and is healthy and endless. This is called generating blood and this is called replenishing qi. There are two meanings. ... Using this in the blood-tonifying flavor can make the old blood harmonious and New blood is generated, that is, those who need to supplement qi due to deficiency also use this as a guide, which is the key to removing deficiency. Han Yu said that it is very fast to remove deficiency." "According to the category of Cyperus rotundus, it is said to regulate qi. However, the causes of qi diseases are different, such as abdominal distension, wheezing, belching, sourness and choking, and stomach pain or heart and stomach pain. The "Ju Fang" generally uses it with fragrant and dry herbs, such as Amomum villosum, Agarwood, Qi Ai, and Ginger. They can only treat diseases of deficiency and cold or cold and dampness, but there are various types of diseases of fire and heat. Moreover, long-term cold and dampness will also turn into fire. For example, Huanghedan is used together with Coptis chinensis, and its meaning is unimaginable." "Cyperus rotundus is often used for qi stagnation, or those with weak and depressed qi must use it together with tonics, which is natural; however, those who have damaged their vital energy due to fire must use drugs to reduce fire and this is used as an aid. If it is generally said to open up the stagnation of qi, it will help fire with dryness, and the weaker the qi, the more depressed it will be. Those who are wise will examine it carefully."
 "Compendium of Materia Medica" states: "Cyperus rotundus is good at relieving depression and dispersing qi. It is similar to costus root in promoting qi, but they are different in nature. Costus root has a bitter taste, so it can promote qi very quickly, while this one is less bitter, so it can mostly relieve depression. It is similar in nature to costus root, so it can be added or subtracted to make a qi-promoting and unblocking agent. Otherwise, this one is suitable but not the other."
 "Compendium of Materia Medica" states: "Cyperus rotundus has a very strong pungent taste and a strong aroma. It is all about qi, so it is specialized in treating qi stagnation. ... In addition, all pungent and warm qi medicines are too strong, which is most likely to dissipate the original qi and stimulate the yang of the liver and kidneys. Moreover, they are often dry and strong, which will damage the yin. However, although this substance has a mild and flowing effect, the substance is hard, so although it is good at moving, it can also stay, not dry and not dispersed, all of which are its unique properties, so it can be used frequently without any side effects. It has always reached the skin and fur, which is completely different from the wind medicine that relieves the exterior. It has always relieved and unblocked, and it is not comparable to the pungent and dispersing medicine that goes up. Haogu said that "Compendium of Materia Medica" does not mention the treatment of metrorrhagia, but it can treat metrorrhagia, which is It replenishes Qi and stops bleeding. Yi said that although it cannot be directly considered as replenishing Qi, it does have the power to lift the sunken. Danxi said that it must be soaked in children's urine because it is too spicy. The following behavior means supervision. Yi believes that this method is most suitable for regulating the liver and kidney. Some people stir-fry it with vinegar or green salt, and the principle is probably the same. ... The various symptoms of Qi stagnation are mostly caused by the liver and gallbladder. This medicine is the most effective in regulating Qi, so Binhu called it a specialist for the foot Jueyin. In fact, chest and flank obstruction, abdominal distension, lower abdominal pain, and hernias are nothing but blocked liver collaterals. The so-called triple-burner Qi division combines the upper, middle and lower parts and runs through them as a whole, regardless of which meridian or collateral it is. "
