Which herbs need to be firstly decocted, secondly decocted, packet decocted, single decocted, melted and blended, rinsed or smashed? Please refer to the introduction by Yixian Pharmacist:

1. Decoct first:Use water to decoct first for 15-30 minutes in advance, then add the other medicines to the same decoction.

Such as minerals, shells, animal horns and nails (including raw keel, raw oyster, raw ochre, raw magnetite, raw alabaster, raw cold water stone, natural copper, raw dragon's teeth, raw corrugated stone, raw gypsum, raw cassia, raw clamshells, raw mother-of-pearl, corrugated stone, tortoiseshell shell, maple dipper, tortoise shell, turtle shell, water buffalo horn, antlers cream, etc.) first decocted to increase the solubility, conducive to the decoction of the active ingredients; such as appendicia, Chuanwu, Caowu, Heichuu, The first decoction of Psoralea, Chuanwu, Caowu, Heichu, Shanglu, Shengnanxing, Shengmianxia, etc. can reduce the toxicity and toxic side effects.

2. Back down:Wait for the other drugs to cook to the last 5 minutes before adding the same decoction. This is because some drugs contain volatile oils, aromatic odor, easy to volatilize, easy to lose the active ingredients, so the decoction time should be short.

For example, drinks containing volatile components such as peppermint, sand nuts, mukong, mouton, patchouli, cardamom, descending incense, incense, fritillaries, etc.; drinks that are easy to destroy the active ingredients after prolonged decoction such as hookah, bitter almonds, Xu Changqing, rhubarb, saffron, senna, etc..

3. Bread frying:Drugs containing more starch and mucus are easy to stick to the pot and become mushy during the decoction process, so they need to be wrapped for decoction.

Drinking tablets containing more mucus, such as psyllium, rabbit seed, silkworm sand, ma bo, scapularia, etc.; drinking tablets rich in fluff, such as xin yi, convolvulus, etc.; pollen and other tiny drinking tablets: such as cattail, hijinsha, clam flour, talcum powder, qingdai, liuyi san, etc. need to be packaged for decoctioning.

4. Single frying:Some valuable Chinese medicines such as ginseng, American ginseng, saffron and antelope horn should be decocted separately.

5、Melting to serve:Some colloidal medicines are very viscous, so if the decoction is mixed, the viscosity of the liquid will be high, which will affect the dissolution of other ingredients, and the colloid will suffer a certain degree of loss. Therefore, it is advisable to add an appropriate amount of boiling water to dissolve the decoction, and then mix with the juice of the medicine to be taken together. Or remove the dregs of the medicine and then put it into the heating, stirring, so that it is dissolved and then taken.

Some gelatinous, honey paste Chinese medicines such as Colla Corii Asini, Antler Gum, Turtle Ape Gum, Turtle Deer Erxian Gum, Caramel, Honey, etc. need to be melted.

6. Punching:Stir the powdered medicine into the decoction and take it. Some precious herbs are made into powders, and the purpose of taking the powder is to fully dissolve and utilize the active ingredients of these precious herbs.

For example, Panax ginseng, deer antler, purple hepatica, herp, money white snake, amber, lei pill, incense, and so on.

7. Smashing:Some Chinese medicines are not easy to decoct because of their hard texture and the active ingredients are not easy to decoct, so they need to be broken up and decocted first, such as minerals, shells and animal horns and nails.

There are several special decoctions for herbs as follows:

1. First decoction: if not specified, the first decoction should be soaked in cold water for 30 minutes, and then decocted for 10-15 minutes and put into other medicines to be decocted together. The medicines that need to be decocted first are usually the herbs that are difficult to be decocted out of the active ingredients and the herbs that have small poisonous substances, such as: gypsum, keel bone, oyster, black appendage, half-summer and so on.

2. Post-decoction: For post-decoction, the post-decoction should be put into the post-decoction 5-10 minutes before the first decoction is ready. Generally, the herbs that need to be placed after the decoction are those containing volatile oils, e.g. mint, glochidon, etc.

3. Divided punch (punch): Divided punch, with the decoction of the medicinal juice to deliver the drug. The medicines that need to be divided and washed are usually powder medicines, such as: Panax ginseng powder, pearl powder, antelope powder, pine pollen and so on.

4, melting: melting the person, the drug into the decoction, constantly stirring, to dissolve it. Need to melt the drug is generally a variety of gelatinous drugs, such as: raw Colla Corii Asini, antler gelatine, tortoise-slab gelatine, etc.

5. Package decoction: For package decoction, the medicine is put into a package decoction bag and then packaged and decocted with other medicines. The medicines to be decocted in packets are usually the herbs that are easy to sink or paste the pot when decocting, e.g.: psyllium, spinosa, etc.

6, another decoction (single decoction): another decoction, the drugs will be decocted separately, and then take the juice. Drugs that need to be decocted separately are usually more expensive Chinese herbs, which are also soaked in cool water for 30 minutes, then boiled over high heat, then slowly decocted over low heat for 15-20 minutes, and the juice is filtered out and mixed with other medicines that are not decocted individually, and then taken together. Examples: ginseng, American ginseng, etc.

7, smashing: that is, the herbs broken or crushed. Need to smash the drug is generally seed herbs, such as: sand nuts, suzi, lycopodium, burdock seeds, etc.

I am a TCM doctor, for you to ask this question then it is a more specialized question.

There is a lot to be said for decoctions in Chinese medicine, especially in ancient Chinese medicine. There is decocting first and then down, melting, and water rinsing and so on.

Usually, the first decoction of the medicine, generally is more often seen in the ore class of drugs, more difficult to out of place flavor of the drug. For example, magnetite dragon bone oyster, cassia seeds, and so on.

There are also other toxic medicines that need to be decocted for a long time to reduce their toxicity, such as the epiphyllum acuminatum and the raw half-summer.

Here the medicine that needs to be boiled for a long time needs to go down first.

As for the latter under the medicine is not long to cook, here if more, containing, aromatic, and rich in volatile oils, here the drug mainly take 'its gas'. One type of medicine is mainly used to treat superficial symptoms. In another category, for example, rhubarb is used for diarrhea, and at this time the other qi of rhubarb is used, which needs to be followed by a descent. If the flavor is taken, there is no need to go after it.

Commonly, there are perilla leaves, mint. Here if, slightly boiled can be used, mainly for sweating to relieve symptoms.

There are also some that simply, just don't need to be boiled. For example, gelatin can be slightly melted while hot. There are others that just melt, such as mangosteen.

A little summary. The efficacy of Chinese herbal medicine relies on the qi and flavor of the herbal medicine. If you use the 'qi' for its effects you can't cook it for a long time, if you need to use its 'flavor' you need to cook it for a longer time.

A lot of knowledge of Chinese medicine, you can follow the headlines of Chinese medicine two sheep.

　　As we all know, the decoction of Chinese herbs is very delicate, such as decoction containers to casserole and clay pots for the best, iron pots, copper pots, aluminum pots and tin pots can not be used for decoction. Now the question: Chinese medicine decoction "first decoction and then down" - is another one of the instructions. So, what is "decoct first and then lower"? What does "first decoct and then decoct" mean? The following is what we are going to talk about.

　　What is "Decocting first and then discharging" in Chinese herbal medicine?

　　The first decoction is to cook this medicine before formally cooking other medicines, that is to say, the first decoction of the medicine is first put into the container with water to be decocted separately, and the general time of decoction is about half an hour, and then it can be put into other medicines to be decocted at the same time. The last drug is the last drug to be put in when the other drugs are about to be decocted. Generally speaking, the last drug only needs to be decocted for 5 to 10 minutes.

　　Why this preoccupation and what are the medications that need to be aware of this?

　　1. Decoct the drug first.

　　Chinese medicine practitioners believe that the drugs that need to be decocted first are mostly the mineral and toxic drugs, such as magnetite, keel bone, cassia, turtle shell and aconite, ochre, oyster, mother-of-pearl, tortoise board, epiphyllum, etc. The hard texture of mineral and toxic drugs can be broken and boiled for a longer period of time to increase the active ingredients in the decoction. The hard texture of the mineral medicine and mesotherapy, etc., broken and prolonged boiling time can be boiled out of the active ingredients, thereby increasing the efficacy of the components in the decoction. And aconite, epiphyllum and other toxic components of the drug is mainly aconitine, long decoction of toxic components can be decomposed, weakened, and the other active ingredients within the drug also increased with the extension of time.

　　2. Post-under medication.

　　The medicines that need to be decocted under the back are mostly those with light dispersive properties and aromatic smells, and also those whose efficacy will be reduced after a long time of decocting, which mainly include woodruff, fresh pellitory, peppermint, salvia, fresh patchouli, and hooker's vine, and so on.

　　The reason why we have to go down also because the aromatic light dispersing Chinese medicine contains volatile oils, which have the efficacy and function of regulating qi and relieving pain, sweating and relieving symptoms, such as mint in which the volatile oils have the effect of sweating and relieving symptoms and fever, and the volatile oils of sand nuts can play the role of regulating qi and relieving pain. If put into the water for a long time will lead to odor dissipation, so that the efficacy of the drug is reduced and lost. In addition, although the hookah is not a drug with aroma and light dispersal, but the active ingredient hookah alkaloids will be partially destroyed after more than 20 minutes of decoction, which will lead to a lowering of the effect of lowering blood pressure, ineffective.

　　Having said that, I believe you already know some of the instructions for decocting herbs, remember to follow your doctor's instructions before boiling them.
