How to decoct herbs? Actually, the method is very simple. 1.2.3 …… Please follow me. I. Decoction tools: Decoction of Chinese medicine can be made in stainless steel pots, enamel pots, casseroles, etc. If conditions do not allow, electric rice cookers and induction cookers for soup at home are also available. Decoction water: decoction water is based on the principle of cleanliness, tap water is fine, there is no need to use pure water, distilled water, etc.. In winter, warm water can be used to make medicine. There are various ways to calculate the amount of water used, but the common one is to visually observe the amount of water added when decocting over 2-3 cm above the surface of the medicine; another one is to roughly estimate the amount of water needed by adding 10 ml of water per gram of herbs as a standard. Third, Chinese medicine soaking: drugs generally do not wash. If the seeds and fruits are the main drugs, they can be soaked for one hour, while herbs in general can be soaked for 40 minutes, and in winter, they need to be soaked for one hour. The “first decoction” medicine is usually boiled for 30 to 60 minutes first. If the drug is poisonous, such as sapodilla, Chuanwu, Cao Wu, etc., it should be decocted for 1 hour first. If the dosage is large, more than 30 grams, it should be decocted for 2 hours. (1) If there is only one kind of drug such as Radix et Rhizoma, Chuanwu and Herba Wu, multiple doses can be decocted first, and later the juice and dregs can be divided into equal parts with each dose of drug and decocted again to save time. (2) If there is a kind of first decoction of Radix Aconiti, Chuan Wu, Cao Wu, Magnet, Dragon Bone, Oyster, etc., it should be divided equally and wrapped with gauze first, and then decocted in multiple doses, and later the juice will be divided equally with the drug in each package of gauze with each dose of drug to save time. Generally the first decoction with water over the drug 5 cm; second decoction with water to submerge the liquid surface of the drug 2 cm higher. Decoction fire: decoction fire is divided into “martial fire” and “civil fire”. The fire refers to the fire, the fire is urgent, the fire is fierce, the temperature rises quickly, the water evaporates more of a decoction method. Wenhuo refers to a small fire, slow, weak fire, temperature change, slow evaporation of water decoction method. Generally, the decoction is first boiled with high fire, and then changed to low fire for 25 minutes. However, some formulas, such as antiphlogistic, antipyretic, and aromatic-based formulas, only use high heat and should not be decocted for a long time with low heat. But some prescriptions, such as antiphlogistic agents, antipyretic agents, aromatic drugs, should not be decocted for a long time with a low fire, so that the taste of the medicine can come out. In addition, the poisonous drugs such as sapodilla, wolfsbane and aconite should be decocted for a long time with low heat to reduce their toxicity. Decoction method: the general decoction method, with a lid on the fire heating decoction. First decoct on high heat, then on low heat. During the decoction process, pay attention to moderate stirring to avoid paste, and also to improve the rate of decoction of the active ingredients of the drug. However, the lid of the pot should not be opened too frequently to minimize the loss of volatile components. After boiling on high heat, decoct on low heat for 25 minutes and then strain the first decoction (if there are drugs under later: cinnamon, sand, etc., they should be added when decocted on low heat for 20 minutes and then boiled for 5 minutes); then add the appropriate amount of warm water, no longer soak, and decoct according to the above method to take the second decoction. Mix the two liquids and take according to the doctor’s instructions. Decoction time: Note that the decoction time is calculated from the time the liquid is boiled. Decoction time: The first decoction takes 15 minutes, and the second decoction takes about 15 minutes. General medicine: 25 minutes for the first decoction and 25 minutes for the second decoction. Tonic medicine: 40 minutes for the first decoction and 30 minutes for the second decoction. Seven, the number of decoction: generally decoction twice. One long decoction cannot replace two separate decoctions. Decoction of soup can be decocted twice to get 80% of the ingredients, so it is appropriate to decoct the medicine twice. The medicine of two decoctions can be mixed together and taken in 2-3 times half an hour after meals (if there are molten drugs such as gum and antler gum, wrap them in cloth and break them up, then introduce the amount of molten drugs into the mixture of the first and second decoctions in a day, and heat and stir to dissolve them). If there are more drugs, it can be cooked 3 times, and the juice of the 3rd decoction can be used as the potion for the next drug soak in order not to waste. VIII. Decoction volume: 100-150ml per dose for children. Adults 400-600ml per dose. If the decoction is too much for children to eat, the decoction can be boiled (concentrated) again with a gentle fire, stirring while boiling, and concentrated to the amount that children can eat. A pair of Chinese medicine can be concentrated to 50-100 ml, and then it can be taken in several doses. IX. Special drugs: In addition, there are some drugs that require special methods to decoct, and these drugs, the pharmacy staff will pack them separately. (1) Decoction first: mesocosm and ore drugs, such as turtle plate, turtle nail, magnetite, substitution ochre, raw iron fall, cold water stone, amethyst, keel, oyster, sea clam shell, mother of pearl, stone cassia, etc., should be spit and decocted first because of their hard texture and difficulty in getting out the taste, and other drugs should be put down 20-30 minutes after decoction to make the medicine decocted fully. In addition, the poisonous drugs such as sapodilla and aconite should be decocted for 30-60 minutes with slow fire to reduce their toxicity. (2) after the drug: aromatic smell, lend its volatile oil to take the effect of drugs such as mint, sand, cardamom, incense, etc., should be put in 4-5 minutes before the general drug decoction to prevent the loss of active ingredients. (3) Melting medicine: gum, viscous and soluble drugs, such as gum, turtle gum, deer horn gum, honey, caramel, etc., should be separately dissolved with the liquid to be taken, or added to the decoction and melted. Because it is easy to stick to the pot and cook scorched, and adhere to other drugs, affecting the decoction rate. (4) Punching medicine: Dispersions, elixirs, water pills, natural medicine juice, and certain precious or aromatic medicines, such as musk, niuhuang, panax notoginseng, liushen pills, raw dihuang juice, etc. Blend the brewed medicine into the decoction or boiling water to take. (5) Separate decoction: Some valuable drugs such as ginseng, American ginseng, rhinoceros horn (substitute), antelope horn (substitute), etc. can be stewed for 2-3 hours in order to preserve their active ingredients as much as possible and reduce the absorption of other drugs by decoction at the same time. (6) Wrapped decoction: Some sticky, powdery and fluffy drugs, such as red stone resin, talcum, whirling daisy, carthamus tinctorius, loquat leaf, pu huang, zao xin tu, etc., should be wrapped in gauze and then put into the medicine pot for decoction.
