The first decoction of Chinese medicine forgot to have an effect

It doesn't have a big impact, you can drink it with peace of mind, minerals, such as gypsum, talc, which have the same effect as you boil for half an hour and boil for two hours, solubility.

There are only so many, no matter how long you boil, it will not increase, followed by animals, such as cannon beetles and whole scorpions.

If it is used to boil medicine, the effective ingredient analysis is very small, boiling for half an hour and boiling for two hours The effective analysis is not much different, and it takes a high-precision machine to compare the difference, and boiling this way of taking is extremely wasteful of medicinal materials, so this kind of medicinal herb doctor generally recommends that the powder be swallowed directly to increase the absorption rate as much as possible, and then say that it is poisonous, such as Chuanwu.

Caowu, cinnabar, these, if you want to take it internally, animal and plant medicinal materials (such as Sichuan, Caowu) doctors will definitely prescribe to you that has been cooked, has minimized the toxicity, if you boil the medicine and then boil hard, it is possible to destroy the active ingredients that are not much, cinnabar is the same as the gypsum and talc in front, and the temperature of boiling medicine can not destroy these mineral toxic Chinese medicine decoction pieces at all.

toxicity.

Of course, there is a decoction first, because the ingredients of that medicine are more difficult to precipitate, so it should be decocted first, if you do not do this, it will affect the efficacy of the medicine to a certain extent. On the other hand, some drugs have a small amount of toxicity and must be decocted first to reduce ***.

Therefore, in the future, you must decoct the medicine according to the doctor's instructions.

Of course, the decoction of the first medicine is some minerals, animal drugs, decoction time is longer than other drugs, otherwise the active ingredient can not come out, or some toxic drugs, decoction first can reduce the toxicity of the drug.

There are some effects, some of them are in chronological order, and it is better to consult a doctor for details.

First put the captured Chinese medicine into the casserole, then add cold drinking water, soak for 20 to 30 minutes, then add water to cover the medicine, put the medicine casserole on the stove and decoction over medium heat. Generally speaking, it is divided into two decoctions, after the first decoction, pour out 150 200 ml of the liquid medicine, called the first decoction: then, add an appropriate amount of warm water (if the residue is cooled and then decoction, cold water should be put when cooking), and the second decoction is carried out, which is called the second decoction.

Sometimes you can also add water and cook the third decoction, or the fourth decoction. This should be done as instructed by the doctor. How to calculate the time of decoction From the time after the water is boiled, there are three cases:

1) It is used for the first acute fever, four seasons external wind cold, wind heat and other diseases of heat and divergent drugs. The first decoction is boiled over medium heat for 15 to 20 minutes, and the second decoction is boiled for another 10 to 15 minutes. 2) Used for ** common chronic diseases, such as:

Physiological drugs for spleen and stomach diseases, visceral dysfunction, hypertension, and cardiovascular diseases. The first decoction is boiled for 20 to 30 minutes on medium heat, and the second decoction is boiled for another 15 to 20 minutes. 3) Tonic drugs for ** debilitating diseases, such as:

Drugs for qi deficiency, blood deficiency, kidney deficiency and other deficiency diseases. The first decoction is about 30 40 minutes after boiling on low heat (simmer), and the second decoction is boiled for another 20 30 minutes. Why do some decoction pieces have to be "back down" when decoction Aromatic drugs, containing volatile ingredients, lose their efficacy after a long decoction time, so they should be put into the pot 5 minutes before other medicines are decocted, and the latter medicine is generally wrapped by the pharmacy and marked with the word "back down".

Medicinal materials containing aromatic and volatile oils, such as cinnamon branches, peppermint, peilan, white kom seeds, sand seeds, cinnamon, agarwood, etc., are all light and clear medicines, and the active ingredients are easy to diffuse with water vapor. For example, if peppermint is boiled for too long, the content of peppermint oil and menthol in the liquid medicine will be reduced, which will directly affect the efficacy.

Some of the active ingredients contained in decoction pieces can be quickly dissolved in water, such as: hook vine, rhubarb, senna, artemisia annua, Xu Changqing, etc., if this kind of medicine is decocted for a long time, its chemical composition may change. For example, if the rhubarb is fried for a long time, the anthraquinones contained in it will be destroyed, and the effect of laxative will be reduced, while if the hook vine is cooked for more than 20 minutes, its blood pressure lowering effect will be significantly reduced.

The preparation of TCM decoction is not too particular, generally soak the herbs for about 30 minutes before decoction, and the decoction effect will be better! Other doctors will tell you!

Even under the same conditions, the degree of deterioration of different formulas varies greatly, and if the liquid contains more starch, protein, sugar, etc., it will deteriorate very quickly. Tests have also shown that the higher the temperature, the faster the liquid deteriorates. Therefore, after the Chinese medicine is decocted, it is better to take it within one day.

1.It can be refrigerated, if it is fried in a decoction machine in summer, it will be stored for a longer time of 7-10 days, as long as the sealed bag does not swell, it will not affect the efficacy.

2.If you fry it yourself in the summer and put it in a drink bottle and refrigerate it, it is best to consume it within three days. (The storage of medicines is also seasonal, and the storage time in winter and spring and autumn can be longer).

Problem analysis: Hello, this kind of decoction can be drunk, now decoction to 20 minutes after pouring out, and then add water to decoction cavity limbs to cook for the third time.

Suggestions: It is recommended that if you decoction three times, there may be a lot of liquid medicine, when the decoction is done three times, then concentrate the liquid medicine to 350 400 ml of both nuclear Shenke, three times a day, 20 minutes after meals.

How long can Chinese herbal medicines be stored?

People often wonder if Chinese herbal medicine has an expiration date like Western medicine. Can I still use some Chinese herbs that I have stored at home for a long time?

For proprietary Chinese medicines, the validity period is generally about three years, and if it exceeds three years, do not use it. However, for the expiration date of Chinese herbal medicine, the country has not yet issued a unified standard, and specific drugs should be analyzed specifically.

Most Chinese herbal medicines are dried and processed, and can generally be stored for a longer time, but some drugs will be stored for too long, and the efficacy of some drugs will be reduced if they are stored for too long, and some volatile drugs can be stored for a shorter time. However, different Chinese herbal medicines do have different expiration dates according to their texture and storage conditions, such as plant and animal Chinese herbal medicines are easy to deteriorate if they are not stored properly, and mineral Chinese herbal medicines are volatile if they are not stored properly, which will lead to a decrease in the efficacy of Chinese herbal medicines. Some Chinese herbal medicines have been stored for too long, although there is no mildew and insect moth in appearance, but the efficacy has been reduced.

Judging from the texture of Chinese herbal medicines, their expiration dates are very different. For example, Coptis chinensis can be stored for 10 years, and tangerine peel is stored for as long as possible, while notoginseng is very hard and not easy to volatile. However, wolfberry and other Chinese medicinal materials containing a large amount of fatty oil are easy to get rid of oil after being stored for a long time, and then such as Huoxiang, peppermint, nepeta, etc., after a long storage time, the volatile oil contained in them will volatilize, and the active ingredients will be reduced.

In addition, special attention should be paid to the natural decomposition, volatilization and sublimation of Chinese herbal medicines that cannot be stored for a long time, such as rosin, the solubility will be reduced after long-term storage, alum and miscanthus nitrate are easy to weathering and lose water after long-term storage, and the active ingredients of digitalis and ergot are easy to decompose after long-term storage. Fresh asaroxin has a strong antitussive effect, and when stored for 6 months, it loses its antitussive effect.

Looking at the temperature, the current temperature should be no problem for a month, and it is recommended to put it in the refrigerator for insurance.

No more than four hours to be exact.

It can be stored in the refrigerator for several days.
