When does Chinese medicine need to be boiled?

In the process of boiling Chinese medicine, only when the time is completely sufficient, can the best effect of Chinese medicine be brought out, and most Chinese medicine needs to be boiled twice to be able to fully exert its medicinal effect. Therefore, people who need to drink Chinese medicine and slowly regulate their bodies need to firmly control the time it takes to boil Chinese medicine each time. So how long does it take to boil Chinese medicine in the normal process to fully exert its effect?

Generally, the first decoction of Chinese medicine takes about half an hour from boiling, and the second decoction can be slightly longer than 10 minutes. The number of decoctions should be 2 or 3 times.

Generally, drugs can be decocted at the same time, but some drugs are divided into various situations such as decoction first, then decoction, no need to decoction, decoction and decoction separately due to their different properties, properties and clinical uses, etc., and it is necessary to follow the doctor's instructions. In addition, Ejiao and other medicinal materials are easy to stick to the pan and boil when decocted with other medicines, so they should be put into water separately or in the decocted liquid medicine to be heated and melted before serving.

It should be noted that the herbs do not need to be over-washed, but it is best to soak them before frying them, and it is better to soak the herbs thoroughly. Compared with flowers, grasses and leaves, the soaking time of rhizomes, seeds, fruits, ores and crustaceans is slightly longer, and half an hour to 1 hour is preferred.

There are two aspects to pay attention to in decoction of Chinese medicine.

1. Do not use boiling water to soak traditional Chinese medicine before decoction.

Some people are accustomed to soaking medicinal materials in boiling water before decoction of traditional Chinese medicine, thinking that this not only shortens the decoction time, but also enables the active ingredients of traditional Chinese medicine to be dissolved as much as possible, but in fact, it is a misunderstanding of lack of scientific understanding, and boiling water can not be used for traditional Chinese medicine.

The proteins contained in Chinese medicine will solidify due to sudden heat when exposed to boiling water, and harden the cell wall, forming a tight cell membrane on the outer layer, which hinders the full dissolution of the inner components. The polymer substances contained in traditional Chinese medicine are easy to form colloids when exposed to boiling water, which is not conducive to the exudation of active ingredients. When the traditional Chinese medicine is cut and crushed, the powder left on the surface is gelatinized due to sudden heating, which obstructs the capillary channel of the medicinal materials, making it difficult for water to penetrate, and it is difficult for the ingredients to diffuse outward after dissolving, which ultimately affects the decoction of the ingredients.

Aromatic Chinese medicines, such as peppermint, perilla, patchouli, sand kernels, cardamom, etc., contain volatile oils and volatile substances, which are easy to volatilize when heated.

Generally speaking, soak in cold water for about 30 minutes before decoction of Chinese medicine; However, some experiments suggest that the optimal water temperature for soaking before decoction of traditional Chinese medicine is 40 50, which not only makes the herbs fully expanded when wet, but also improves the decoction rate of active ingredients.

2. Do I need to cover the lid for decoction of Chinese medicine?

To decoction the slices of traditional Chinese medicine thoroughly, so that the active ingredients in the medicine can be fully decocted, it should be covered and decocted. In particular, when the decoction contains ingredients that can volatilize with water vapor, such as peppermint, Huoxiang, sand kernels, etc., it is best to cover and decoction. In this way, the water vapor containing the volatile components of the drug can be agglutinated in the lid and become water droplets drip back into the medicine tank, thereby reducing the loss of the active ingredients of the drug.

Traditional Chinese medicine is boiled in a casserole, avoid using iron utensils, pour the medicine into the casserole and add water, the water is 1 to 3 cm away from the medicine surface, first soak it for more than half an hour, and then increase the fire to boil.

The decoction time of Chinese medicine is generally determined according to the properties of the medicine.

1.For the sweating and relieving surface, regulating qi, light texture and aromatic volatile medicine, the water should be boiled and then fried for 10-15 minutes; For sticky tonic medicines, boil water and then simmer for about an hour.

2.Some medicines have a special decoction method due to their different textures.

1) Some active ingredients are insoluble in water, such as gold, minerals, and shellfish drugs should be broken and decocted first, boiled for 20-30 minutes, and then decocted with other drugs, so that the effective ingredients can be analyzed, such as raw gypsum, turtle plate, turtle shell, etc.; Aconite, aconitum and other drugs with strong toxicity should be decocted for 45-60 minutes to reduce toxicity.

2) Some aromatic drugs, the active ingredients are easy to volatilize and reduce the efficacy of some fragrant drugs, so they must be put in after boiling other drugs for 5 10 minutes, such as mint, sand kernels, etc.

3) For some precious medicinal materials, in order to better decoction of the active ingredients, they should be decocted separately for another 2-3 hours. The decoction can be taken separately or mixed with other decoctions, such as ginseng, American ginseng, deer antler velvet, etc.

How long does Chinese medicine need to be boiled? Generally, Chinese medicine will need to be boiled for about an hour, and then boiled two or three times, and the potion is poured together and synthesized before drinking.

Soaking before decoction: the first decoction (once) is generally soaked for 30 minutes, and the main drug can be soaked for 1 hour with seeds and fruits as the main medicine; The second frying (second) does not need to be soaked again. For each decoction of more than 2-5 cm of medicinal liquid, add water to the second decoction, and the liquid can be submerged in the medicinal liquid.

The time it took to boil Chinese medicine was related to his illness. If you boil a cold for 5 to 15 minutes you can. If the medicine for the stomach and intestines takes more than half an hour. If you want to make a tonic medicine, it takes about 45 minutes.

Traditional Chinese medicine has mineral drugs to decoction for 30 minutes, some Chinese medicine is toxic, prolonging the time of decoction can reduce the toxicity without reducing the efficacy of the decoction should also be decocted for 30 minutes or longer, and the general medicine should be decocted twice, 30 minutes each time. Mix the medicine and discard the slag. There are also some aromatic herbs that need to be lowered.

In order to avoid the volatilization of the medicinal effect, this kind of medicine is added at the end and fried for about 10 minutes.

Generally, the best time to boil Chinese medicine is to fry slowly for more than 1 hour on low heat, so as to make the efficacy of the drug better, so as not to affect the effect of the drug if the heat is not properly mastered, and it will not play a good role. The container for decocting Chinese medicine is generally a casserole, an enamel pot or a stainless steel utensil, not an iron utensil. The decoction time of drugs with different effects is also different, and it is generally advisable to clear the pyrolysis surface for 15-20 minutes after boiling.

After boiling, switch to low heat and cook for 40-60 minutes.

The best time for boiling Chinese medicine is 40 to 60 minutes, and the specific decoction time of Chinese medicine needs to be determined according to the medicinal materials, generally including ordinary decoction of medicinal materials, including decoction of medicinal materials and medicinal materials containing later medicinal materials.

1. Ordinary decoction of medicinal herbs.

Soak the medicine in cold water for 30 to 60 minutes, and the amount of water soaked in Qiao's bubble should be submerged 3 5 cm of the medicine surface, and then put the medicine in a pot and boil it over high heat. After boiling, switch to low heat to maintain a slight boiling state, slow down the evaporation of the water surface, and facilitate the dissolution of the active ingredients. After switching to low heat, start the timer, generally fry for 40 to 50 minutes.

2. Contains decoction of medicinal herbs.

Soak the medicine in cold water for 30 to 60 minutes, and the amount of water soaked is appropriate to submerge the surface of the medicine 3 5 cm. Boil the decoction for 20 to 30 minutes, then put the other drugs soaked in the casserole, and then fry for another 20 30 minutes after the water boils.

3. Medicinal materials with the lower back.

First, soak the medicine in cold water for 30 60 minutes, and the amount of water soaked is appropriate to submerge the surface of the medicine 3 5 cm, and then put the medicine in a pot and boil over high heat. After boiling, switch to low heat to maintain a slight boiling state, slow down the evaporation of the water surface, and facilitate the dissolution of the active ingredients. Start the timer after switching to a low heat, add the medicine before turning off the heat, and wait until the smell of the medicine is dissipated.

The number of times a dose of Chinese medicine is boiled:

For Chinese herbal medicines, which are mainly flowers, leaves, stems and other medicinal materials, it is usually possible to exert the medicinal effect after taking the medicine twice in one dose. Generally, it can be soaked for 20-30 minutes before decoction, which is conducive to effective composition analysis. The first frying time is usually about 30 minutes, and the second frying time is usually about 20 minutes.

If the amount of medicine is too much, or the texture of the drug is dense, such as magnets, cold water stones and other minerals, you can boil three times and then mix the liquid medicine, and the time of three decoctions is usually about 15 minutes. It is recommended to soak for 30-60 minutes before decoction, which is conducive to the filling and analysis of active ingredients.

If it is a traditional Chinese medicine mainly used for external scalding, it does not have to be limited by this, and generally a Chinese medicine can be boiled 2-4 times repeatedly, and some can even be boiled more than 5 times.
