Is it good to soak Chinese medicine for a long time? Will Chinese medicine lose its effect if it is

Not good. Don't soak for too long. Soak for half an hour to 1 hour.

Soaking before decoction: the first decoction (one decoction) is generally soaked for 30 minutes, and the drugs mainly seeds and fruits can be soaked for one hour; When decoction (second decoction) again, do not soak again. The amount of water added to the first decoction exceeds the drug by 2-5 cm, and the second decoction can be added with water to submerge the drug.

Number of decoctions: Generally decoction twice. One long frying is not a substitute for two split frying.

Decoction heat: Generally, use high heat (martial fire) before boiling, and keep it slightly boiling with low heat (simmer) after boiling. For anti-episodic and aromatic drugs, it is advisable to fry them over high heat to avoid volatilization of medicinal properties and reduced efficacy; For tonic medicine, it is advisable to fry it on low heat for a long time to make the active ingredients of the medicine exhausted.

Decoction time: general medicine, the first decoction should be boiled and then fried over low heat for 20-25 minutes, and then fried over low heat for 15-20 minutes after the second decoction; 10-15 minutes for one decoction and 10 minutes for two decoctions; The first decoction of the tonic is 30-40 minutes, and the second decoction is 25-30 minutes. The longer the decoction is not always better.

Special decoction: The small packet of medicine filled with "decoction first" in the medicine bag is decocted for 30 minutes before adding group medicine; The small packet of medicine injected with "back down" should be put into the decoction 5---10 minutes before the group medicine is decocted; A small packet of medicine with "Bao decoction" is wrapped with gauze and put into the medicine group to fry together; A small packet of medicine filled with "Xuanhua" is taken after decoction and dissolution with the decoction of the decoction liquid and the "Xuanhua" medicine; A small packet of medicine with "Wash" is used to take it with a decoction.

What do you mean?

Boil the medicine three times, first submerge the Chinese medicine with water, and soak for 20 minutes.

Boil for the first time (no more water) for 20 minutes, strain into a bowl and set aside.

Boil for the second time, add the same amount of water, boil for 20 minutes, strain into the bowl for the first time, and set aside.

Boil for the third time, also add the same amount of water, also boil for 20 minutes, filter into the bowl of the first two times, and mix the medicines that have been boiled three times together and drink.

After boiling, switch to a simmer, and when the fire is high, it will be boiled dry.

There are several advantages of decocting traditional Chinese medicine in this way: first, it solves the problem of "thousands of boiling water", second, it can remove a lot of impurities, third, it can avoid the harm of heavy metals such as lead, and fourth, it will not lose the active ingredients in traditional Chinese medicine, and play a role in seeking benefits and avoiding disadvantages.

A considerable number of Chinese medicine decoction pieces contain more polysaccharides, so that after steaming and drying, if not fully soaked, the active ingredients of the drug can not be fully dissolved. For example, Aracea, Banxia, Yam, Aconite, Polygonatum Polygonatum, Polygonatum polygonatum, Polygonum multiflori, etc., so it is best to soak for about two hours.

You can try it yourself, only soak for half an hour and soak for two hours, and the color of the liquid will be much different.

The active ingredient of the drug will be lost if it is exposed in the air for a long time, and it will be lost due to the action of oxygen in the air after soaking for a long time, and it will be decomposed due to the action of bacteria, but no one will soak the decoction pieces in it for several days or even years, so such a loss can not be considered.

In fact, some pharmaceutical ingredients will lose a lot after being boiled for a long time, such as peppermint containing volatile ingredients, and hook vine, which will cause the destruction of active ingredients after a long time of cooking.

Also: The water used to soak the medicine cannot be poured out, it is used for decoction for the first time.

Generally, soak for 25 minutes and fry for another 50 minutes. If you take an antidote, which is what we often call cold and fever medicine, the effect of the medicine will be lost after a long time, and nothing else will be done. Provided it hasn't gone bad.

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.

1. Soak the Chinese medicine in cold water for a period of time before decoction.

2. The soaking time is determined according to the drug, and the loose texture of the drug, such as flowers, leaves, and thin stems, can be soaked for half an hour; Drugs with hard textures such as roots, rhizomes, seeds, and fruits should be soaked for 1 hour; For mineral, animal, and shellfish drugs, the soaking time needs to be longer.

3. However, it should be noted that the soaking time should not be too long, especially in summer, so as not to deteriorate the drug. The soaking time is shorter in the summer and slightly longer in the winter, and the general rule is that the higher the room temperature, the shorter the soaking time. The water in which the medicine is soaked should be used directly for decoction and cannot be poured out.

Problem analysis: Chinese medicine should be soaked for a period of time before decoction, so that the effect can be effectively exerted.

Guidance: Before decoction, soak the Chinese medicine in cold water for a while, if it is a leaf or flower, soak it for about an hour. If it is a root or fruit, it is generally soaked for more than two hours.

At the same time, it is also necessary to consider seasonal factors, such as the soaking time in summer is shorter, and the winter time is slightly longer, the general principle is that the higher the room temperature, the shorter the soaking time.
