Most of the decoctions are fried by the compound. The pharmaceutical ingredients are quite complex. They are generally soluble in water and poorly soluble in water. They are also volatile. They are prone to destruction, decomposition and coking. In order to increase the amount of decoction, reduce the loss of volatile substances and the decomposition and destruction of active ingredients, improve the quality of decoction, and ensure the efficacy, depending on the different properties of various drugs, they should be treated separately when they are fried. 1. The purpose of first frying first is to increase the solubility of the drug, reduce the toxicity of the drug, and fully exert the effect. (1) Ore: Shellfish, horny drugs, due to the hard texture, the active ingredients are not easy to fry, must be fried first. Such as raw gypsum, cold water stone, red stone fat, magnetite, amethyst, white quartz, substitute meteorite, sea pumice, goose tube stone, ochre, stone, natural copper, oyster, stone cassia, mother of pearl, jellyfish shell , corrugated, turtle shell, armor, pangolin, keel, dragon tooth, tiger bone, leopard bone, armor, buffalo horn, etc., can be broken and fried for 30 minutes. (2) Toxic drugs: such as aconite, aconite, snow on an artemisia, landing money, commercial land, traces of steamed bread, etc., must first fry for 1-2 hours, first fry, long fried can achieve the purpose of attenuating or detoxification. Aconitine is poisonous because it contains aconite. Long-term decoction can decompose aconite into aconite, which is decomposed into aconite. Its toxicity is only 1/2000. Aconite can not only reduce toxicity, but also enhance the heart. Calcium aconite calcium produces calcium ions when heated, and has a strong heart effect of synergistic demethylated aconite. (3) Certain botanicals: such as Tianzhu yellow, Tibetan green fruit, and hemp seed only effective after first frying. Dendrobium contains lactone biopterin, only the long-decoction hydrolysate works. 2. The purpose of the lower, lower and lower is to reduce the loss of volatile oil, and the active ingredients are free from decomposition and destruction. (1) Aromatic aromatics, drugs containing more volatile oils, such as mint, musk, woody, soybean meal, Amomum, red cardamom, cardamom, sandalwood, fragrant, agarwood, artemisia, rose, asarum, etc. After the next, usually in the Chinese medicine decoction 5 ~ 10 minutes before the fried medicine can be used. (2) drugs that should not be fried for a long time, such as uncaria, almond, rhubarb, senna, etc. should be followed. 2. Uncaria has a hook vine, fried for 20 minutes or more, and its antihypertensive component is destroyed. Almonds contain bitter almonds, which can hydrolyze a part of the long-term decoction, produce hydrocyanic acid and escape with water vapor, weakening the antitussive effect. For the impenetred almonds, the hydrolysis is more rapid due to the action of the enzyme. Rhubarb takes its diarrhea effect, because the effect of rhubarb diarrhea is stronger than 甙元, so it should not be fried for a long time. Generally, it is fried in 10 to 15 minutes before frying. 3. Pack fried (1) Pollen drugs, such as powdered pollen, Puhuang; small seeds, such as medlar, scorpion, and dodder; drug fine powder, such as Liuyisan, sputum, etc. should be fried. Although these drugs are small in volume, but the total surface area is large, the flow of the particles is strong, the surface tension is large, and it does not come into contact with the water surface due to insufficient contact. Therefore, it is necessary to wrap the gauze with other drugs into the casserole. (2) For drugs containing more starch and mucus, such as glutinous rice, floating wheat, and psyllium, it is easy to paste and coke during the boiling process, so it needs to be fried. (3) For the attachment of fluffy drugs, such as invertebrate, etc., take the package frying, to avoid the swelling of the villi into the soup to stimulate the throat, causing cough. 4. Sputum rushing into some gums or sugars, viscous, such as gelatin, turtle shell glue, staghorn gum, sika deer, spatholobus, honey, sugar, etc., should be added with appropriate amount of boiling water, Rush into the soup or take it into the soup. If mixed, it will cause the viscosity of the liquid to be large, affecting the dissolution of other ingredients, and the glue will also suffer some loss. 5. Decoction water is generally bulky. The drugs with large water absorption, such as loofah, stove heart, money grass, japonica root, etc. should be boiled with water, and the obtained juice will be decoctioned and then fried. 6. Dissolving such as mirabilite, Xuanming powder, etc. can also be dissolved into the decoction application. 7. After frying, add some valuable drugs such as ginseng, American ginseng, velvet antler, etc., and the juice can be taken into the fried decoction. 8. Raw juice is mixed into fresh raw juice, raw oyster festival, pear juice, leeks juice, ginger juice, Rhizoma chinensis juice, bamboo leaching, etc., should not be fried into the cooked decoction. 9. A combination of certain valuable pharmaceutical active ingredients that are not dissolved in water or that are easily decomposed after heating, such as ginseng powder, bezoar powder, antelope powder, notoginseng powder, musk powder, whole meal powder, cinnamon powder , Ganzi powder, etc., the drug is combined with the fried decoction and stirred. 10. Go to the simmering honey for the convenience of the patient, to supervise the toxicity of the drug, and to extend the efficacy of the drug. For example, "Golden Dragonfly" Fangda Wutou fried, with a large head of Wutou (熬 peeled, not xx Tsui), with three liters of water, boil one liter, go 滓, 纳蜜二å‡, fry water , take two liters. In the clinic, we found that when individual patients take aconite medicine and have side effects of stomach discomfort, they can often eliminate this side reaction by adding decoction.
