Processing of vinegar-roasted traditional Chinese medicine

Vinegar, called bitter wine in ancient times, is also called vinegar and acyl. Its taste is sour and bitter, and its nature is slightly warm. In the traditional processing method of traditional Chinese medicine, vinegar is a commonly used liquid auxiliary material. The processing of drugs can affect the channels of drugs and have a selective effect on the human body. Vinegar tastes sour in the liver meridian. Vinegar is also a good solvent, which can improve the dissolution and precipitation of effective components of some drugs, correct the smell and taste, and reduce the toxicity of drugs. Vinegar for processing traditional Chinese medicine includes frying vinegar, boiling vinegar, quenching vinegar and steaming with vinegar.

Li Shizhen in Ming Dynasty introduced in Compendium of Materia Medica: "There are several kinds of vinegar: rice vinegar, wheat vinegar, koji vinegar, bad vinegar, chopped vinegar, peach vinegar, grape vinegar vinegar, jujube vinegar and doll vinegar, and those who know it are extremely sour. However, rice vinegar has been used as medicine for two or three years, and the rest can only be spit out and no medicine is allowed. " 6% acetic acid plays an important role in vinegar, and it also contains compounds of grape acid, succinic acid, amino acid, lactic acid, sugar, salt and vinegar. Taking medicine with vinegar has the following three important functions.

1, vinegar should be stored to remove odor:

For example, Oletum Trogopterori is the dry feces of flying mice, which has a fishy smell and a bitter taste. After frying with vinegar, the odor is removed, sterilized and preserved, which has the function of promoting blood circulation and relieving pain. Another example is natural copper, ochre and magnets, which are hard in texture. After calcination, it is soaked and quenched in vinegar, which is crisp and easy to grind, and the effective components are decocted. Curcuma zedoary is hard and soft after being boiled with vinegar, which is convenient for slicing. It can also be used as medicine to enter the liver, promote digestion and relieve pain. There are also monkey bones, tortoise shells and tortoise shells, which can be fried with sand first and then soaked in vinegar to remove the fishy smell and make the texture crisp. The combination of vinegar and calcium salt of bone shell can generate soluble salt compounds, which are easy to crush and decoct into effective components.

2, vinegar can eliminate drug toxicity:

Some drugs are very toxic, and processing with vinegar can reduce the toxicity. For example, Kansui, Euphorbia Euphorbia and Daphne genkwa are bitter, cold and toxic products, which are extremely unsafe to eat raw, but their toxicity is greatly reduced after being processed with vinegar. Take Daphne genkwa as an example. Just leave it for a few years. When you use it, you will cook it with good rice vinegar for more than a dozen times, and then soak it in vinegar for one night. When the vinegar dries, the poison goes out. Vinegar can detoxify, which is the experience summarized by the ancients in long-term practice.

3. Vinegar can lead to channel tropism:

In the Ming Dynasty, Chen Jiamo said in Vinegar Mooncherry: "The price of medicine is moderate. If it is not enough, the effect is hard to find. If it is too big, the smell will disappear. Wine will rise, ginger will disperse, and vinegar will hurt the liver. " In traditional Chinese medicine, the location of pathogenic factors is usually summarized by meridians and viscera, and the introduction of drugs as meridians, that is, the processing of accessories, can make drugs play a role in a certain part and have more curative effects. "Su Wen? Zhi Zhi's Theory of Medicine also points out: "Five flavors enter the stomach, and each is happy. Vinegar enters the liver first, bitter enters the heart first, sweet enters the spleen first, pungent enters the lung first, and salty enters the kidney first ... "For example, Bupleurum can raise yang and relieve fever, and after vinegar is made, it can soothe the liver and relieve depression, which has a stronger effect; Cyperus rotundus is on the surface when it is raw, and on the waist and knees when it is cooked. Decocting with vinegar will eliminate accumulation, enter the liver to relieve pain, promote qi circulation and relieve depression. Steaming Schisandra chinensis with vinegar can enhance the effects of relieving cough, vomiting, diarrhea and sweating; Another example is Corydalis yanhusuo, which is used for removing blood stasis, promoting qi circulation to relieve pain, and returning to menstruation with vinegar, and can treat irregular menstruation, blood gas attacking the heart, and chest and abdominal pain. Modern pharmacological analysis shows that Corydalis yanhusuo contains a variety of alkaloids, which combine with vinegar to form acetate, so it has stronger analgesic effect and more obvious curative effect.
