Abstract: The method of drawing fire to its source is a basic rule for treating upper heat and lower cold. Upper heat and lower cold can occur in many diseases, and the rational use of this method can achieve good results. Key words: fire-directing method, transmission, experience summary The fire-directing method is the basic rule for treating upper heat and lower cold, which can occur in many diseases. The condition often has its own development pattern, which is often manifested as dry eyes, dry throat, pain at the tip of the tongue, dizziness, palpitations, and wheezing at the top, and loose stools or diarrhea, cold abdomen, frequent nocturnal urination, cold pain in the waist and knees, and numbness and coldness in the lower limbs. The symptoms may develop into syncope. The case of pharynx is the gateway to the lung, the kidney meridian is the pharynx, the deficiency of kidney yin can lead to Shaoyin kidney fire house can hide the place, directly run and inflammation in the pharynx and become sore throat or moth. Hu a female 34 pharyngeal pain, dry throat, drink does not quench thirst, take clear heat and detoxification medicine does not work, less abdominal fear of cold and swelling, usually easy palpitations, like to drink cold and stomach discomfort, tongue red, lips red, pulse thin number inch pulse floating guan ruler sinking dialectical evidence on the heat and cold, qi and yin two deficiencies, fluid can not follow the gas up tide, imitating Chen Shiduo lead fire soup to princely ginseng 30 XuanShen 30 MaiDong 30 WuWeiZi 6 Cornus serrata 12 yam 30 ShuDi 30 BaJiTian 3 three doses and healed Clear? Chen Shiduo’s “Dialectical Qi Wen” used the “Fire Inducing Soup” to treat Yin moth, swelling and pain in the throat, light day and heavy night, moth in the throat, drinking water into the abdomen, then abdominal restlessness, vomiting saliva like water. Chen Shi believes that because Shao Yin kidney fire is not hidden in the lower part of the body, it runs straight up and inflames the throat. The treatment should be a great tonic for Shao Yin kidney water, less tonic fire, in order to nourish Yin and submerge Yang. The patient’s body is not only a good source of fire, but also a good source of water, so the kidneys are not at risk of dryness. This patient, although the lips are red, pulse number, but less abdominal cold, drink does not quench thirst, usually palpitations is the heart of the Qi-Yin deficiency, cold does not cold means no fire, so the subtle yang to guide the fire to the source method was effective. Second, diarrhea case diarrhea is mostly due to the spleen and stomach failure to lift the cause, and five more often by the kidney and the vital gate of the deficiency of cold, water cold and fire can not be warm, water is a big diarrhea. Patient Du, female, 65 years old, came to the clinic with diarrhea as the main complaint, with previous history of cardiac arrhythmia and palpitations. She had a history of cardiac arrhythmia and palpitations. She went to the ophthalmology department because of dry throat and astringent eyes and suspected dry syndrome. He had dry eyes, palpitations, numbness and coldness in the lower abdomen and lower extremities, abdomen must be pressed with something to make it comfortable, frequent nocturnal urination, dark tongue, thin white moss, and sunken pulse. This is a deficiency of spleen and kidney yang, with upper heat and lower cold. At the initial consultation, we did not ask about all the symptoms, so we used Si-wei-san with additional flavor. As the use of Radix Rehmanniae, Radix et Rhizoma, Radix et Rhizoma Ginseng, Radix et Rhizoma Mulberry, Radix et Rhizoma Chrysanthemum, etc. in the past would aggravate the diarrhea, indicating non-real fire and coldness in the lower jiao, generally those with deficiency of yang energy in the lower jiao are more sensitive to cool medicines and prone to diarrhea. 3 Baji Tian 10 diarrhea stopped after the medicine, urine normal, not up at night, dry mouth and eyes significantly reduced, through this case have the following experience, 1. Yin and soften the liver, increased the amount of peony, dry symptoms significantly reduced, and Baji Tian is a very good fire to the source of medicine. Chen Shiduo created fill Kan Tang both spleen and kidney tonic, divide water to stop diarrhea, Cornus officinalis 30 Fu Ling 30 Baji Tian 15 Cinnamon 9 Che Qian Zi 9 Bei Wu Wei 9 Ginseng 9 Gorgonian 30 Atractylodes macrocephala 60 formula in Baji Tian, Cinnamon warming the vital Qi, tonic yin in addition to its fire, then the Yang is able to ingest yin. Chen’s use of Baji Tian from 6 grams to 30 grams ranging. The case of syncope, Chen Shiduo, Qing dynasty, “Dialectical Qi Wen”, the door of stroke, people have fainting after a long period of dysentery, the lower part of the more dead yin, yin deficiency and Yang storm syncope, the lack of heart qi is extinguished, with the only ginseng soup, ginseng 90 sophora 3 points to return Yang to save off. Numbness of both hands and face is not a stroke, but a deficiency of qi to transport the blood. He was a female with diarrhea for 19 years, coughing and wheezing for 5 years, and paroxysmal perioral and hand clonus for 1 year. She has been unable to eat for 2 weeks and visited the clinic because of syncope. She likes to hold cold things in her hands, likes hot drinks, and has a cold abdomen. Therefore, it is known that he is suffering from syncope of upper heat and lower cold. The disease is caused by diarrhea, diarrhea for a long time, more yin is lost under the diarrhea, prolonged coughing hurts the qi, liver yin deficiency and deficiency of wind moves inside, therefore, paroxysmal contractures around the mouth and hands, yin deficiency and yang violent convulsions, heart qi is lacking for syncope, yang floats outside so the hand likes to hold cold things, abdomen is cold as the image of yang deficiency. Yin and Yang deficiency, treatment from the spleen and kidney. The patient was later diagnosed with colon cancer by colonoscopy and pathology, and also underwent surgery. Although the diagnosis was not conclusive two years ago, indicating that the patient’s condition was developing and relatively heavy. The Chinese herbal medicine regimen bought time for further examination and surgery and improved the overall condition. Although the patient said that deficiency is not tonic, in fact it is not possible to tonic Qi alone; tonicity makes the upper heat worse. Instead, strengthening the spleen and tonifying kidney yin while drawing fire back to its source is actually a tonic. Chen Shiduo: The medicine for Yang can be used sparingly to achieve success, while the medicine for Yin must be used more often to obtain results. Yang is the main ascender and Yin is the main descender. Yang up, less use of Yang medicine and gas easy up; Yin down, less use of Yin medicine and taste difficult to reach down. Therefore, the use of rehmannia 1-8 two, and cinnamon 1-2 money. Discussion: The sutra said: “drink into the stomach overflowing essence, upward transmission in the spleen; spleen qi dispersed essence, up to the lungs, through the water channel, down to the bladder; water essence four cloth, five parallel meridians, combined in the four seasons, the five organs of yin and Yang, consider the degree for the normal”. The transmission of the spleen and stomach depends on the transpiration of kidney energy. The stomach is the gateway to the kidneys, and the kidney qi is sufficient for the stomach qi, while the lung is the main qi, the respiratory division, and the lung qi is sufficient for the water channels to be transferred down to the bladder. Patients may suffer from spleen injury due to heart strain, or Qi injury due to strain, or gastrointestinal injury due to diet, or imbalance of qi transmission due to lack of emotion and will, which may result in loss of yin in the lower part of the body and fire in the upper part of the body, resulting in heat in the upper part of the body and cold in the lower part of the body, which may lead to syncope. Chen Shiduo “dialectical wonders” often use a small amount of cinnamon, sapodilla, baji Tian to induce fire back to the source, the treatment of upper heat and lower cold, involving a wide range of diseases, sapodilla as little as 3 points as much as 9 grams, baji Tian dosage up to 30 grams . In the process of dialectical treatment, the clinical evidence often uses the boswellia to draw blood downward, cinnamon, bacopa monniera to draw fire back to the source, to achieve the purpose of Yin and Yang balance. The Yang tonic can be used sparingly to achieve success, while the Yin tonic must be used more to take effect. Yang is the main ascender and yin is the main descender. Yang ascending, less use of Yang medicine and gas easy to ascend; Yin descending, less use of Yin medicine and taste difficult to reach down. Rehmannia 1-8 taels, and cinnamon 1-2 money. Zhang Xichen, “Medicine Zhongzhong Ginseng Xilu,” both Ji Tang, shamrock 30g, rehmannia 30g, raw yam 18, raw dragon peony 18, poria 9, raw peony 9, Wu Shuizi 3g, treatment of all yin and yang deficiency, upper heat, lower cold, upper bloom, lower deficiency. I experience, liver yin deficiency, the big agent white peony with the sapodilla, dry throat with Xuan Shen Mai Dong moisten the lung Qi kidney water, kidney yin deficiency, Shu Di shamrock with the sapodilla at the same time with licorice to solve the sapodilla poison cold signs obvious with the sapodilla, not obvious with the bacopa monniera is better. For common conditions such as dizziness, astringent eyes, sore throat, sore tongue, palpitation, palpitation, asthma, insomnia, diarrhea, etc., if the manifestation of upper heat and lower cold, the upper is strong and the lower is weak, can be used to induce fire to the source. Due to the difference in degree, there is the difference between heart fire, liver fire, dragon fire, constipation and diarrhea, and the difference between lower jiao kidney deficiency and lower jiao yang deficiency. Treatment should be treated differently.
