Professor Feng Chunxiang, a professor at Beijing University of Chinese Medicine and a member of the Expert Committee of Beijing Famous Medical Hall, pointed out that Chinese medicine decoction seems simple, but it is very professional. Besides conventional soaking, the time and method of decoction should be reasonably selected according to the different characteristics and efficacy of drugs.
Soaking is an essential and important link before decocting traditional Chinese medicine, which is related to whether the effective components of the medicine can play a role!
Traditional Chinese medicine is mostly dried products of plant roots, bark leaves, flowers and fruits. After harvesting and processing, most of the water has evaporated and the cell fluid has dried up. Soaking before decoction can make cells swell again, which is beneficial to the dissolution of effective components of drugs. Because the surface of medicinal materials is easy to form a film after contacting with water, the medicinal materials should be stirred with water before soaking.
The soaking time depends on the nature of the medicinal materials. Generally, flowers are soaked in herbs mainly including whole grass for 20-30 minutes, and roots, rhizomes, seeds, fruits and other herbs can be soaked for 60 minutes. However, the soaking time should not be too long, so as not to cause enzymatic hydrolysis of the effective components of the drug or mildew of the drug.
● Grasp the decocting time.
Most traditional Chinese medicines only need to be decocted for 30 minutes after being fully soaked, but the decocting time of exterior-relieving drugs and tonics is different. For example, exterior-relieving drugs are usually boiled for 10 minutes, while tonic drugs need to be boiled with slow fire for about 40 minutes.
● Don't touch the medicine.
This detail is easily overlooked by everyone. Generally speaking, most of the bought Chinese medicines are wrapped in paper, and many people are used to touching them by hand when putting them into the decocting container.
In fact, this action may sometimes affect the curative effect of traditional Chinese medicine. If you don't wash your hands and apply hand cream, it's easier to pollute Chinese medicine. Therefore, in the process of pouring medicinal materials into the container, it is best not to touch the medicine with your hands, but to pour it directly.
● When cooking Chinese medicine, some need to be stamped.
In order to thoroughly fry the Chinese herbal pieces and fully fry the effective components in the medicine, it is best to cover and fry them. Especially when the decocted medicine contains components that can volatilize with water vapor, such as mint, agastaches, Amomum villosum, etc. It is best to cover the fried clothes. In this way, the water vapor containing volatile components of the medicine can condense into water droplets in the cover and drip back into the medicine pot, thus reducing the loss of effective components of the medicine.
For most root-fixing, seed or animal medicines, such as ginseng, astragalus, Polygonatum, Ophiopogon japonicus, Schisandra chinensis, gecko, keel, oyster and so on. It should also be covered with decoction, so that more effective components of the drug can be decocted in a limited time to improve the curative effect of the drug.
For those traditional Chinese medicines with loose texture and large volume, such as loofah sponge, medulla tetrapanacis, mushrooms, chrysanthemums, mulberry leaves and so on. Don't cover it when decocting, stir it at any time to make it fry evenly.
Traditional Chinese medicine pays attention to four qi and five flavors, and forms a prescription according to the cold, heat, warmth and coolness of drugs and referring to the five flavors of pungent, sweet, sour, bitter and salty. Only by grasping the correct medication time can the best therapeutic effect be obtained. But the time to take Chinese medicine depends on the condition and the nature of the medicine.
Is it taken before or after meals?
Generally speaking, patients with chest symptoms and above, such as dizziness, headache, sore throat, cough and other symptoms, should take it after meals; Symptoms in the chest and abdomen, gastrointestinal, liver, kidney and other problems, to eat before meals. If the patient feels uncomfortable after taking it before meals, it is recommended to take it after meals when taking drugs that stimulate the gastrointestinal tract, because there is more food in the stomach after meals, which can reduce the stimulation of drugs;
In addition, patients with chronic diseases need to take medicine regularly; Tonic drugs are greasy and hinder the stomach, so they should be taken before meals; Sedative hypnotics should be taken before going to bed; People who vomit should take a small amount of frequency; People with acute diseases and throat diseases can take decoction instead of tea and take it regularly.
Chinese medicine is bitter, how to take it?
Under normal circumstances, the soup is taken warm; Pills, powders and other traditional Chinese medicine preparations are generally taken with warm boiled water.
Because Chinese medicine is bitter, some people like to add sugar to Chinese medicine, which is inappropriate. Whether sugar can be added depends on the doctor's advice, otherwise it will affect the curative effect.
In order to reduce the retention time of drugs in the oral cavity, you can hold your breath, drink Chinese medicine continuously in one breath, then rinse your mouth with warm water, or send the liquid medicine directly to the root of your tongue with a spoon to facilitate swallowing.
