What are the precautions for decoction of Chinese medicine?

Soak the medicine in cold water for half an hour, depending on how much you dosage to decide, generally speaking, it is a finger of the medicine surface, fry for half an hour, and fry the cold medicine for 10 minutes after boiling! Chinese medicine is divided into decoction and then down, what does the doctor say how to decoction, the first decoction is to fry for 10 to 20 minutes after the left, and then the medicine is boiled for 15 minutes and put in the decoction for 5 minutes! The warmth and heat you are talking about, cold is nothing to pay attention to when the doctor does not specify it, and if it is hot, wait until it is cold before drinking, there is no problem!

And what kind of pot you said, the most particular thing is to use a purple casserole, but now there are a lot of fakes, you can use the kind of pot used to make a casserole in a general hotel, and you can buy it outside! The pot is not very particular now! Just don't get scammed!

The clay pot must be used to make Chinese medicine, and it has a small mouth for water, and the reason is to maintain the original flavor of the medicine and the effect is good. Generally, dry herbs can be soaked for about ten minutes, just after the herbs have been soaked. Then after boiling, switch to slow heat to an appropriate amount, pay attention not to be too cold when drinking, and keep it at about 40 degrees to have an effect.

Casserole or aluminum pot.

Soak in cold water for 1 hour, the water is not medicated.

Fry for about 30 minutes, about a large bowl (400ml) of the medicine, add water, about 20 minutes, about a bowl (300ml) of the medicine

Pour it together twice and stir well.

Warm (slightly warm).

Generally, a clay pot is used, because the clay pot is not easy to react with the drug. Not all medicines have to be soaked, and the general tonic medicine is only soaked, and the soaking time is generally about 20 minutes. Antidotes are generally not foamed. Generally, it is good to wear warm.

Let's make a clay pot for medicine.

It takes about half an hour to brew the medicine, but it doesn't take too long.

Let's serve it hot.

1. Soak before decoction.

Generally, cold water is added to spread over the medicinal surface, soaked and then decocted, so that the active ingredients are easy to decoction. Generally, it can be soaked for about 30 minutes, but it should also be treated separately according to the weight of the texture of the herb itself, the difference in season and temperature. Flowers, grasses, and leaves can be soaked for 20 minutes; Rhizomes, seeds, fruits, ores, and crustaceans should be soaked for 30 to 60 minutes.

In short, the soaking of medicinal materials shall prevail.

Second, the choice of decoction utensils.

The decoction container is very closely related to the quality of the liquid medicine, and historical records believe that "silver is the first, and the magnetic is second", and it is not recommended to use tin, iron and other pots for decoction. Because some drugs will precipitate after encountering metals such as tin and iron, reduce solubility, and even cause chemical changes, resulting in ***. At present, it is mostly advocated to use ceramics and clay pots instead of iron pots and copper pots, and it is best not to use aluminum pots and stainless steel and enamel containers to decoction to ensure the efficacy of traditional Chinese medicine.

3. The choice of decoction water.

Water is the most commonly used solvent for decoction of Chinese medicine, and it is generally advisable to use clean cold water, such as tap water, well water, distilled water, etc. The amount of water used should be determined according to the weight, volume, water absorption capacity, decoction time, heat and required dosage of the drug, and it is generally advisable to overflow the drug by about half an inch. The amount of water used for decoction should be added at one time, not to add water several times in the middle, and then add water to decoction after the decoction is dry, and the decoction should be discarded.

Fourth, the heat of the decoction.

There are "martial fires" and "simmers" in decoction of traditional Chinese medicine, "martial fire" for rapid frying, and "simmering" for slow frying. Generally, martial arts are used first, that is, high heat is used at the beginning, and then simmering is used after boiling. Different recipes require different decoction times.

The decoction time of diaphoretic antidote for external symptoms should be short, and the decoction time of tonic drugs for deficiency syndrome should be long.

There are the following precautions for decoction of Chinese medicine:

1. The best choice of decoction utensils is crockpots and casseroles, followed by enamel and stainless steel utensils, and iron and copper utensils can not be used to decoction;

2. Do not wash the medicine before decoction, because the active ingredients of some Chinese medicine decoction pieces are water-soluble, they will be lost with cleaning, and some medicines are in powder form, which will also be lost during the cleaning process, which will affect the efficacy;

3. Before decoction, after the decoction pieces are properly pressurized, the liquid surface should be submerged about 3cm over the decoction pieces, and soaked for about 30 minutes, which can make the active ingredients easy to decoction;

4. Decoction of Chinese medicine

A lot. The first is to soak the medicine, first soak and then decoction. There is also the order in which the drug is administered.

Some medicines are not easy to smell and should be taken first, such as gypsum and tortoise shell. Some can't be fried for a long time, such as mint, which should be lowered later. Finally, there is time, first bring to a boil over high heat, then simmer.

The time should not be too long.

You can choose an aluminum pot or casserole to cook the decoction, which usually does not affect the efficacy of the medicine, and it is necessary to avoid the phenomenon of sticking to the pot when boiling the medicine.

Traditional Chinese medicine cannot be used in an iron pot during decoction, so as not to have a chemical reaction with the drug, and in severe cases, it will also lead to poisoning, so this must be avoided. Generally, you can choose an aluminum pot or casserole to cook the decoction, which usually does not affect the efficacy of the medicine, and it is necessary to avoid the phenomenon of pasting the pot when boiling the medicine.

1. First of all, in the selection of decoction utensils, casseroles should be preferred, followed by enamels, avoid aluminum, iron, copper and other metal utensils, because these utensils may have a chemical reaction with traditional Chinese medicine ingredients, reduce the efficacy or produce poison.

2. Secondly, before decoction, soak the medicine in water for 30-40 minutes, and the decoction water can be used well water, spring water, tap water, and the amount of water added should be about two fingers of the drug.

3. When decocting the medicine, boil it over high heat first, and then change to low heat and boil it slowly for 20-30 minutes.

Although there are many dosage forms of traditional Chinese medicine, they are mainly prepared by pharmaceutical companies and hospital preparation rooms, and the decoction is mostly cooked by the patients themselves, and if the decoction is not regular, it will affect the efficacy and drug safety.

Different diseases and different groups of people have special requirements for decoctions, especially some prescriptions have stricter requirements for decoctions. Here I will mainly introduce to you the decoction method under normal circumstances, please follow the doctor's instructions in special cases.

1. General decoction method.

1.Decoction utensils It is advisable to use ceramic utensils such as casseroles and casseroles that are not easy to chemically react with the ingredients of the decoction, and have uniform heat conductivity and good warmth performance. Do not use iron, aluminum, copper and other metal utensils for decoction.

Because metals are easy to react with traditional Chinese medicine ingredients, it may reduce the efficacy and even produce toxicity.

2.The amount of water used in decoction When decocting Chinese medicine, the amount of water added to the decoction should include the amount of water absorbed by the decoction piece, the amount of evaporation during the decoction process and the amount of medicine required after decoction. The amount of water added to the second decoction should be subtracted from the water absorption of the decoction pieces.

Usually, the amount of water added can only be estimated according to the density of the texture of the decoction pieces, the strength of the water absorption performance, and the length of time required for frontal imitation and decoction. The general feasible practice is that after the decoction pieces are properly pressurized for the first decoction, the liquid level should be higher than the decoction pieces, and the water surface of the second and third decoctions can not exceed the medicinal materials.

3.Soaking before decoction Before decoction, the decoction pieces should be properly soaked in cold water, which is not only conducive to the dissolution of the active ingredients, but also shortens the decoction time, so as to avoid the loss or destruction of the effective ingredients due to the decoction time being too long. If the decoction pieces are directly decocted without soaking, the starch and protein on the surface of the decoction pieces will swell, blocking the capillaries, making it difficult for moisture to enter the inside of the decoction pieces, and it is also difficult for the active ingredients of the decoction pieces to diffuse outward.

Generally, medicines should be soaked in cold water, and some medicines need to be taken at a specific time. For example, malarial interception drugs should be taken before the onset of malaria There is a certain scientific reason for taking the drug and avoiding the mouth, which is also a summary of long-term clinical experience. In order to.

There is an article:

Preparation before decoction.

1. Soak the Chinese medicine for 20-30 minutes.

Soak the Chinese medicine for a period of time, so that the medicine can better absorb water, so that the decoction of Weiyou decoction has a better therapeutic effect. It is best to choose cold water for the water soaked in the herbs, because if the water temperature is too high, the starch in the herbs will gelatinize and the protein will coagulate, so that the active ingredients of the drug will not be dissolved during decoction. In addition, do not rinse the herbs with water, many people think that the herbs should be washed first so that they feel, in fact, this washing will make the active ingredients of the herbs lose and reduce the efficacy, especially the herbs that have been ground into powder should not be washed.

2. The decoction utensils are exquisite.

If you want to decoction Chinese medicine, the choice of utensils is also very important, and good utensils can better dissolve the active ingredients of Chinese medicine. It is best to choose casseroles, enamels, clay pots, and glassware for decoction of Chinese medicine, and do not use aluminum, copper, and iron utensils.

3. Wrap the herbs in cotton cloth.

If you need to make the herbs into a medicine pack, it is best to choose cotton gauze to wrap the herbs, which is done to make the herbs easily soluble in water.

4. Decoction with cold boiled water.

It is best not to use tap water for decoction of Chinese medicine, because tap water contains chlorine, which will destroy the active ingredients of Chinese medicine, and after the tap water is boiled, the chlorine will volatilize, which can reduce the probability of loss of the active ingredients of Chinese medicine.

Precautions in decoction.

1. The amount of water.

For decoction of traditional Chinese medicine, the water should be 3 cm to 5 cm higher than the surface of the medicinal materials, and the amount of different decoctions should be more prescribed by the doctor, and do not add water at will when decocting Chinese medicine.

2. Cooking time.

Some people think that the longer the decoction of Chinese medicine, the stronger the decoction of Chinese medicine, the better, but this is wrong. The decoction of traditional Chinese medicine reaches the highest value of the active ingredient of the liquid medicine for a certain period of time, and if it is constantly decocted, it will cause the active ingredient to evaporate continuously and decrease, reducing the efficacy of the medicine. Excessive medicinal decoction can also cause nausea, vomiting and other adverse reactions after taking it, so the decoction time should not be too long.

3. Martial arts before literature.

The advantage of using simmering is that it can reduce the evaporation of water, and it can maintain a boiling state, which is conducive to the dissolution of the active ingredients of the drug.

4. Stir frequently when decocting the medicine.

The decoction is not the herbs put in the pot to burn, the decoction process of the medicine often observe the decoction, to stir frequently, to avoid boiling the Chinese medicine paste or decoction.

1.decoction of Chinese medicine before bai

Chinese herbal medicine DU must be soaked, preferably for about 30 minutes.

zhi2.After soaking, you can start frying, and you can also decoct the medicine with the gas stove version, and the pot power is best ceramic, specially used for decoction.

3.When decocting the medicine, he should be guarded by the side, and when he is about to boil, he should immediately turn off the low heat, otherwise the water will come out. The Registers.

Don't touch the medicine with your hands.

It seems that it is not a good thing to grasp medicine with your hands, but people who often eat soap or apply hand cream when washing their hands every day should pay attention, and most of the Chinese medicine they buy back is wrapped in paper packaging, and some are small packages made of plastic bags. When putting the medicine into the decoction container, many people's hands will touch the Chinese medicine, but they don't know that this action will sometimes affect the efficacy of the Chinese medicine, if the hand cream or the aromatic smell of soap has been applied to the hand at this time, it is a kind of pollution of the Chinese medicine. Therefore, it is best not to touch the Chinese medicine with your hands, and you should pour it directly into the container.

Don't use an iron pot. The decoction container is best in a casserole and clay pot; glass containers, enamel containers (intact) are second; Iron, copper, aluminum, and tin pots cannot be used to decoction medicines. "This is because the chemical composition of traditional Chinese medicine is very complex, and due to the reactive chemical properties of metals such as copper, iron and aluminum, it is easy to react with the chemical components in traditional Chinese medicine.

For example, iron is easy to form iron tannins with tannin, which deepens the color of the liquid medicine, and makes the liquid medicine have a rusty smell, which affects the efficacy of the medicine; Hail stool aluminum reacts with organic acids to form compounds that are absorbed by the human body and accumulate in liver, kidney and other tissues, causing damage to the human body; Bronze is easy to oxidize when heated, and produces patina that is harmful to the human body. These will affect the quality of the decoction, which is directly related to the clinical efficacy of the decoction.

In addition, some people will also use the casserole used for cooking at home to decoction the medicine, so it is necessary to pay attention to the need to wash it cleanly, so that there will be no oil splashes on the surface after putting in clean water. Because the oil will affect the efficacy of traditional Chinese medicine.

3. Use distilled water.

Water quality can also have an impact on the efficacy of Chinese medicines. For example, Li Shizhen divides the decoction water into five kinds, such as rainwater, dew, snow water, etc., which are natural distilled water, which are less harder and purer than ordinary spring water, river water and well water, and can reduce the impact on the active ingredients of the drug to the greatest extent. Although we can't pursue water quality like the ancients, if conditions allow, we can use distilled or purified water, which can also be cooled and boiled.

Tap water can be heated to remove chlorine, but you can't use hot water or boiling water to decoction directly, and you can only let it cool.

Many people use bottled water to boil when decocting medicine, but mineral water contains minerals and metal ions, which also has an impact on the efficacy of the medicine.

The following table is examined.

Anyone who has seen traditional Chinese medicine may have noticed that if it is a self-decoction of traditional Chinese medicine, the doctor will generally explain that a pair of medicinal decoctions is done twice, and the decoction is mixed together before and after.

The application of traditional Chinese medicine is a common treatment method for Chinese people. There are also many things to do when it comes to decoction of Chinese medicine.

The choice of container is often the first consideration, because traditional Chinese medicine contains a lot of tannic acid or other alkaloids, when encountering iron or other metals, it can make biochemical changes in the composition of traditional Chinese medicine, which can reduce the effectiveness of the light medicine, and produce toxic substances that endanger human health. For ironware, it should be avoided, and aluminum products should also be avoided.

Before decocting Chinese medicine, it is usually necessary to check it to recognize which ones are fried first and which ones are washed, and cannot be mixed together for decoction. Some Chinese medicines, such as magnets, keels, oysters, turtle plates and other harder Chinese medicines, should be crushed and then fried.

The medicine of the motherland once emphasized the use of well water or spring water to decoction of traditional Chinese medicine, but now it is generally believed that clean cold water is sufficient, unclean river water and pond water should not be used, and some people like to use boiling water decoction is also inappropriate.

Before the decoction of traditional Chinese medicine, it is usually necessary to soak it, and the tonic drugs used for chronic diseases are often soaked for half an hour to 1 hour.

The amount of water added to each dose of Chinese medicine should refer to the number of Chinese medicine formulas, the length of decoction time, and generally add more than 2 3 cm of water to the surface of the medicine, so that the decoction of the liquid is 150 200 ml. The heat of decoction of Chinese medicine is also very important, the general principle is to fry slowly on low heat, and the decoction of medicine in the household electric stove is difficult, and it is often difficult to master the heat, so it is not suitable to choose. The time of decoction is usually determined according to the doctor's instructions, generally speaking, different Chinese medicines or different diseases, the time required to decoction of Chinese medicine is not the same, wind and cold antidotes, emergencies, to be quickly decocted, generally 5 10 minutes; Strong tonics, chronic diseases, decoction of Chinese herbs for a long time, up to 1 2 hours.

For example, the application of traditional Chinese medicine honeysuckle, chrysanthemum, perilla leaves, dice, houttuynia cordata, large green leaves, purslane, plantain and other traditional Chinese medicine based on flowers and leaves, or cinnamon, tangerine peel, sand kernel, Huoxiang and other traditional Chinese medicine containing more volatile oil, should not be fried for a long time, about 10 minutes or so, and astragalus, codonopsis, angelica, turtle plate, turtle shell, Morinda officinalis, cistanche and other medicines, should be fried for half an hour to 1 hour. Some old Chinese medicine practitioners believe that ginseng should be steamed over a slight heat for up to 2 to 3 hours; Some Chinese medicines, such as Nanxing, Banxia, Aconite, etc., contain toxicity and should be decocted first to reduce toxicity; Some powders (Qingdai) and small granules (psyllium, sulforaphane) should be wrapped in gauze before they can be decocted. Generally, Chinese medicine needs to be decocted twice (first decoction and second decoction), some people decoction once in the morning and evening, take it with decoction, and some people decoction 2 times in a row, mix the liquid medicine together, and take it in 2 times.

The requirements for decoction of Chinese medicine should be combined with the specific conditions of the region, season and family, and the instructions of the Chinese medicine practitioner should be followed to ensure that the Chinese medicine is used reasonably and plays its due effect.
