 【Predecessors release medicine】
 Zhang Yuansu: Dry ginger is pungent in nature, but slightly bitter after being roasted, so it stops but does not move, and is therefore able to treat internal cold, unlike aconite which moves but does not stop. The reason why it is used in Lizhong Decoction is that it can restore yang.
 Li Gao: Dried ginger is pungent when raw and bitter when roasted, which is yang. It is used raw to expel cold pathogens and release the exterior, while roasted ginger can remove stomach coldness and protect the center. Using too much ginger will dissipate the vital energy, and the pungent taste can disperse it, which is because it strengthens fire and consumes qi. Raw licorice should be used to slow it down. The pungent and hot taste can disperse the interior cold, and it can be used with Schisandra chinensis to warm the lungs and with ginseng to warm the stomach.
 "Compendium of Materia Medica": Dried ginger can lead blood medicine into the blood and qi medicine into the qi. It can also remove evil and nourish newness, which means that yang gives birth to yin, so it is used for blood deficiency. It is also suitable for people who vomit blood, bleed from the nose, and have yin but no yang. It is a method of treating heat with heat.
 "Ben Cao Jing Shu" states: Pao Jiang, pungent in nature, can dispel evil and resolve knots, and warm in nature, can dispel cold and relieve air, so it can cure chest fullness, cough, reverse breathing, warm the middle and induce sweating, expel wind and dampness, dysentery caused by cold, and stop abdominal pain. The reason why it says it stops bleeding is that blood deficiency causes fever, and heat causes blood to flow indiscriminately. Dry ginger fried until black can lead all blood-tonifying drugs into the yin part, and when blood is replenished, yin is generated and fever subsides, and blood does not flow indiscriminately. It can also cure intestinal obstruction, which is also its meaning.
 "Compendium of Materia Medica": If the lower abdomen is cold and weak, and there is abdominal pain and diarrhea, warming and nourishing should be used. If there is postpartum deficiency heat, excessive deficiency fire and spitting blood and bloody diarrhea, stir-fry and use it. If it is fried until it is charcoal-black, it has lost its ginger properties. It is also used to stop bleeding, and its black and astringent properties are used. If the yin is strong and suppresses the yang, the fire does not return to the origin, and the yang is weak and cannot absorb blood, and there is vomiting blood, epistaxis, and bleeding, it is best to stir-fry it until it is cooked and retain its properties. It is the most important medicine for stopping bleeding.
 "Pharmaceutical Chemistry": Dry ginger has been dried for a long time, and its body is contracted, and its qi is released, and its taste is reserved. It is more spicy and hot than fresh ginger, so it can stop but not move, and is specifically used to disperse the cold inside. For example, if the patient has abdominal pain and cold body and diarrhea, and the whole grain is not digested, it can be combined with licorice to take the meaning of pungent and sweet combination to transform into yang. It is added to Wuji San to help disperse the superficial cold and treat cold pain in the lower abdomen; it is added to Lizhong Tang to treat cold cholera and stop loose stools; it helps with aconite to clear the cold of the meridians, and has a great power to restore yang; it is mainly used with ginseng and tangerine peel to warm the middle qi, and has the effect of returning to the root. Fresh ginger is mainly used to disperse, while dry ginger is mainly used to protect, and they are very different. ... Paojiang can reduce false heat.
 "Compendium of Materia Medica Chongyuan": "Shennong Benjing" only has fresh ginger and dried ginger, but no roasted ginger. Later generations roasted dried ginger until it turned black, and called it roasted ginger. "Golden Chamber Synopsis" uses licorice and dried ginger soup to treat pulmonary tuberculosis, and the dried ginger is also roasted: this is the use of roasted ginger, and Zhongzu was the first. Ginger tastes spicy, and roasting it slightly reduces the spicy taste. It is mainly used to treat postpartum blood deficiency, fever, and internal cold, vomiting blood, epistaxis, and blood in the stool. If it is over-processed, the essence does not exist, and it is called ginger charcoal. It tastes slightly bitter and not spicy, and its quality is light and unreal, and it is not as effective as roasted ginger. Even if you use roasted ginger, you must use the mother ginger from Sanqu Kaihua to be effective.
 "Compendium of Materia Medica" states: Dry ginger is very hot and non-toxic, it stays in the body and does not move. When the stomach is cold and the primordial yang is about to be exhausted, it can be used with aconite to restore yang and have an immediate effect. Therefore, there is a sentence in the book that aconite cannot be hot without ginger. Zhongjing's Sini, Baitong, and Jiangfu Tang all use it. It can also be used with Wuwei to clear the lung qi and treat cold cough, with Baizhu it can dry dampness and nourish the spleen, and with Guishao it can enter the qi and produce blood.
 【Special meaning】
 Yunjiang is also dried ginger, but what makes it special is that it is an authentic medicinal dried ginger unique to Sichuan.
 Yunjiang is produced in Yunlian, Qianwei and Muchuan in Sichuan, hence the name "Yunjiang". It is a unique variety with a long history, dating back more than 1,700 years since it was first recorded.
 In terms of medicinal value, compared with dried ginger produced in other places, Yun ginger has the effect of warming and nourishing. It is spicy and warm without being dry. It warms the middle and dispels the cold inside, stays without moving, promotes blood circulation, and improves immunity.
 The Huoshen School, a local Chinese medicine school in Sichuan, uses a lot of Yunjiang and Chuanfu in its prescriptions, with the idea of one guarding and the other moving, which complement each other. It takes advantage of the special nature of Yunjiang as dried ginger.
 Yunjiang is different from dried ginger made from ordinary ginger. Yunjiang is warm but not dry, not as spicy as dried ginger, but it can go all the way down to the lower Jiao. Yunjiang can warm and nourish the upper, middle and lower Jiao.
 As the only export-grade medicinal dried ginger that meets the requirements of Japanese Kampo medicine, most of the annual output of Yunjiang is directly supplied to Japan. On the contrary, few Chinese doctors use it. Even many Chinese medicine practitioners have always believed that Yunjiang is equivalent to dried ginger. This is sad and sighing. In fact, before liberation, Japan and Germany had set up medicine shops in Qianwei, Sichuan to purchase Yunjiang; in the early days of liberation, the former Soviet Union conducted trade with my country and specifically requested Qianwei dried ginger.
 Medical practitioners must know this.
