Formulas, also known as tonics, are organic combinations of multiple herbs whose ultimate purpose is to correct the imbalance of the body’s internal organs. According to Chinese medicine, the disruption of the balance caused by diseases to the human body is multi-faceted and multi-linked, such as wind-cold colds, cold invasion of the human body, can cause both the human body sweat hole opening and closing obstacles, and will lead to nasal blockage, lung qi can not be declared and other pathological changes, in the combination of drugs to form the soup head, we must consider the main and secondary importance of these pathological changes, and “the ruler, minister, adjuvant, and the In order to achieve good therapeutic effect in the treatment of diseases, we should consider the priority of these pathological changes and the “ruler and minister” and reflect them in the prescriptions. ”This is the principle of composition of prescriptions in Chinese medicine. It was written in the early years of the Western Han Dynasty in Suwen? It was written in the early Western Han Dynasty: “The main disease is called the ruler, the supporting ruler is called the minister, and the responding minister is called the messenger”. The Ming dynasty doctors further elaborated: “Generally speaking, each medicine has its own main treatment, the main treatment, the ruler; auxiliary treatment, the minister also; and the opposite of the ruler’s medicine and help each other, adjuvant also; guide the scriptures to make the medicine of the disease to the disease, make also”. It can be seen that the monarch is the main drug for the main disease or the main evidence, the main role of the drug, according to the needs of the available one or several flavors; the monarch dose is the largest, the significance of the monarch drug is to enable the full play of the medicinal properties of the drug, without the influence and control of other drugs, it is like cooking, the relationship between the main ingredients and side ingredients must not be reversed, so as to ensure that the color, aroma and taste of the main ingredients can be fully reflected. The minister is the drug that assists the ruler to strengthen the treatment of the main disease or the main evidence, or the drug that plays the main therapeutic role for the part-time disease or the part-time evidence; the minister is also the drug that can play a supporting role for the ruler. Here, “help” has two meanings: one is to assist and strengthen the main link of the disease for the monarch to play a therapeutic role, and the other is to play a certain therapeutic role for the secondary link of the disease or part-time evidence. The adjuvant is to assist the ruler and minister to play a therapeutic role, or to treat secondary symptoms, or to eliminate or reduce the toxicity of the ruler and minister, or to be used to counter the adjuvant, so that the drug is a drug to induce or harmonize the effect of the meridian. Adjuvant has three meanings. One is adjuvant. Cooperate with the monarch and ministerial drugs to strengthen the therapeutic effect on the disease. Secondly, it is an adjuvant. It eliminates the toxicity of the ruler and the minister, or restrains the harshness of the ruler and the minister. The third is anti-adjuvant. If the nature of the disease is cold, it should be treated with hot drugs, but if the cold is heavy, it will have a resistance to the hot drugs, so that the hot drugs can not play their proper role, then the method of “anti-adjuvant”, such as adding a small amount of cold drugs to a large number of hot drugs. The medicine also has two meanings, one is to induce the meridians, and the other is to harmonize. “Harmonize” also contains two layers of meaning, one is to harmonize the nature of the medicine, and the other is to harmonize the taste of the medicine. The role of harmonization is to harmonize and unify the different characteristics of various drugs, so that all kinds of drugs can be integrated into a whole, so as to maximize the effectiveness of each drug in treatment. Sometimes we need to use “meridian-attracting” drugs. Chinese medicine has the characteristics of meridians. Different drugs can have special therapeutic effects on different meridians or internal organs. When treating diseases, certain drugs with prominent meridian-attributing effects can be selected to guide other drugs to better act on diseased meridians and internal organs, which is called “guiding the meridians” in Chinese medicine. Through the guiding effect of meridian-led drugs, the effect of drugs on the diseased meridians and internal organs can often be enhanced. For example, for headache, if the headache at the solar plexus belongs to Shaoyang meridian, you can add Chai Hu, which has prominent effect on Shaoyang meridian, to the prescription; if the headache at the top of the head belongs to Jueyin meridian, you can add Wu Ju Ju, which has prominent effect on Jueyin meridian, to the prescription; if the pain at the back of the head, which involves the neck and neck, belongs to Sun meridian, you can add Qiang Wu, which has prominent effect on Sun meridian, to the prescription; if the headache at the forehead belongs to Yangming meridian, you can add Qiang Wu, which has prominent effect on Yangming meridian, to the prescription. The headache in the forehead belongs to Yangming meridian, so you can add Bai Zhi, which has a prominent effect on Yangming meridian, to the prescription as a meridian inducing medicine; the headache involving the teeth and cheeks belongs to Shao Yin meridian, so you can add Hosanna, which has a prominent effect on Shao Yin meridian, to the prescription as a meridian inducing medicine; the headache accompanied by diarrhea belongs to Tai Yin meridian, so you can add Cang Zhu, which has a prominent effect on Tai Yin meridian, to the prescription as a meridian inducing medicine, etc. The “medicine guide” important can not be missing Chinese medicine soup often need to use the “medicine guide”. This medicine introduction is to take its role in inducing the meridian. The medicine can make the role of various drugs concentrated in a certain part or internal organs. Such as the treatment of kidney Yin deficiency of six flavors of Dihuang Wan, commonly used light salt water delivery, because the salt can enter the kidney, can lead to the concentration of drugs in the kidney, in order to give full play to the therapeutic effect: (1) enhance the efficacy. For example, in the treatment of wind-cold cold, pungent and warm relieving drugs, often adding ginger or onion as a drug inducer, can enhance the efficacy of sweating and relieving symptoms. (2) detoxification effect. Some raw drugs are toxic, adding the drug can reduce toxicity, such as ginger can reduce the toxicity of raw nancellus, raw half a summer, ginger is the drug introducer. (3) Taste correction. Some Chinese medicines are bitter and hard to swallow or have a bad taste, such as the formula to bear bile powder, often use brown sugar as a medicine primer, can reduce the bitter taste. (4) Stomach protection. Some drugs can affect the digestive function and stimulate the gastrointestinal tract, affecting digestion and absorption. Such as clearing heat and detoxifying white tiger soup, bitter cold defeats the stomach, often used japonica rice or jujube as a guide to protect the stomach to support the right. The method of decoction is very important The medicinal power and efficacy of Chinese medicine are closely related to the method of decoction. Decoction casserole is best, should not use aluminum or iron pot. Because when decocting, some herbs and metal components are prone to chemical reactions that change the nature of the drug and reduce its efficacy. Soak in water before decoction. Water has strong penetrating power to herbs and can dissolve active ingredients such as alkaloids glycosides, organic acids, tannins, proteins, sugars and inorganic salts in herbs, so it is the most commonly used solvents for decocting herbs. Natural cool water refers to cool unpolluted well water, river water, spring water and tap water, which is calm in nature and tastes more sweet. Before decocting, soak the medicine in water and add the amount of water that is 3cm above the surface of the medicine after the herbs are submerged. The most suitable soaking water temperature for Chinese herbs before decoction is 40℃-50℃. Through soaking, the water can slowly penetrate into the herbs’ tissues and make the structure loose and swollen, resulting in a good solubilization environment so that the active ingredients can be easily decocted. Soaking time depends on the herbs, such as 30 minutes for flowers, leaves and grasses with loose and frivolous texture; 1 hour for roots, stems and bark of plants grown for many years. Traditionally, the first decoction should be filled with water 3 cm-5 cm above the surface of the medicine, while the second decoction should be filled with water 1 cm-2 cm above the surface of the medicine. 300-500 ml of water should be added to the first decoction of general drugs, 250-300 ml to the second decoction; more water should be added to tonic drugs, 700-1000 ml to the first decoction, 400-600 ml to the second decoction. 150 ml of soup should be added to both decoctions of any drug. Pay attention to the decoction of individual drugs before and after decoction. Some drugs require special decoction methods to achieve the desired effect. For example, mint, patchouli, hooked vine, pelargonium, and sand, etc., should be included when other drugs are about to be decocted and decocted for one or two boils; gypsum, dragon bone, oyster, ochre, magnet, mother-of-pearl, stone cassia, tortoise shell, etc., should be decocted for about half an hour before being decocted with other drugs; poisonous drugs such as epiphyllum and aconite should be decocted first in a separate package; spinach, loquat leaf, haijin sha, and mab, etc., should be decocted after being wrapped in cloth; syrup, etc., should be decocted after being wrapped in cloth. The decoction should be made after the cloth is wrapped; syrup and honey should be added after the medicine is decocted; gum, antler gum and tortoise shell gum should be taken after the medicine is decocted; rhinoceros horn, deer antler and panax ginseng should be finely grounded and taken with boiling water or medicine soup. When decocting medicine, you should master the fire correctly. Use warm fire at the beginning of the decoction, and use low fire after boiling. The lid should not be removed frequently to prevent the smell from dispersing and to reduce the spillage of volatile components. Boil for 10-15 minutes for general drugs, and 30 minutes for tonic drugs, so that the active ingredients can be fully decocted. The decoction time depends on the medicine, generally speaking, the first decoction is calculated from boiling for 20 to 25 minutes, while the second decoction is 15-20 minutes. If there are hard medicines such as mineral shells, they must be broken up and decocted for 30 minutes first. Do not take the decoction. Some drugs contain volatile oil, once cooked, the volatile oil is lost, that is, the effective sweating and antipyretic effect is lost, and it will produce toxicity, so it should be prohibited. Common special decoction method: first decoction: generally refers to the mineral shells or the active ingredients are difficult to decoction of drugs, there are toxic substances also need to be first decoction, such as aconite, sophora. Or according to the need of the drug itself and the condition of the disease, some drugs in the formula should be decocted first, such as ephedra in Ge Gen Tang. Separate decoction: In order to avoid decoction of the same drug to reduce the efficacy or reduce the side effects caused by the same decoction, sometimes the formula is decocted separately and then combined and taken or decocted again, such as Lily Zhi Mu Tang. Wrapped decoction: Certain herbs with hairy or tiny volume or high amount of mucus or easy to become paste after decoction are wrapped up and decocted, such as spinach, psyllium, etc. Post-decoction: Drugs containing volatile oil or active ingredients that fail after a long decoction, such as peppermint, mullein, rhubarb, senna, etc., are usually added when the decoction is almost ready for a total of 4 minutes-5 minutes, such as decoction of licorice ephedra soup to be followed by licorice. Melting: Some solidifying gums such as gum, antler gum, etc., the main components are colloidal proteins, amino acids, calcium, when decocted with other drugs, it is easy to dissolve and adhere to other drugs or burnt pot, so the soup should be melted and served. That is, take the prescribed amount of gum herbs and add the right amount of water to stew and close, then stir into the decoction and serve. The therapeutic effect of the medicine is often closely related to the time and method of taking. The time of taking soup medicine: in general, it is taken 2 hours before eating and divided into 3 times a day. It can also be taken at the right time according to the condition. Pulmonary diseases should be taken after meals, while kidney diseases and lower limb diseases should be taken before meals. Patients with liver disease should take it at noon and at night before going to bed. The dosage should be small for all products with great bitterness, coldness, pungency and heat. The dosage of the products that strengthen the spleen and benefit the qi, eliminate food stagnation and replenish the qi and blood can be large. The use of highly toxic drugs should be careful, the dosage should be small. The dosage of drugs that play a major role should be large, and the dosage of drugs that play a secondary role should be small. The specific dosage can be determined according to the patient’s constitution, age and disease. The method of taking the soup medicine: generally take the medicine by warm. For fever, the liquid is cooled and then taken. It is suitable for those who are critically ill to take it at once. For heart disease and nourishing Yin and stomach medicine to be taken before bedtime. Suitable for bladder disease and kidney tonic to be taken 30 minutes before meals.

The medicine solution is not easily dissolved in water or should not be decocted medicine powder should be brewed. Pills, ingots, and pills that take effect slowly should be taken in the mouth. There are contraindications during the taking of medicine. The main one is to avoid the mouth to ensure that the medicine works better and to avoid adverse reactions.
