Where there are rocks in the river, the water in front of the rocks is blocked, forming a countercurrent.

The curative effect of decoction is not only related to the accuracy of syndrome differentiation and the appropriateness of prescription, but also closely related to the decocting method of drugs. Among them, the choice of decocting water is an important factor.
Traditional Chinese medicine decoction generally takes water as the solvent (there are other solvents, such as vinegar and wine). First, soak the medicine in it, and decoct as many effective ingredients as possible through long-term decoction. The water used for decocting medicine seems simple, but it is actually complicated. In fact, water is both a solvent and a medicine. In many herbal works such as Symptomatic Materia Medica and Compendium of Materia Medica, water appears as medicine at the same time. Not only that, but also its properties, functions and indications are listed in detail.
Ancient doctors divided water into many kinds. For example, there are many kinds of water in Medicine True Story, such as long water, fast water, smooth water, countercurrent water, thousands of miles of water, half-day river water, spring rain water, autumn dew, snowflake water, well flower water, fresh water, rootless water, chrysanthemum water, running water, lily water, moon cave water and so on. The reason why the ancients gave so many names to water was actually under the influence of China's traditional thinking, which combined the properties and functions of different kinds of water. In the eyes of the ancients, the nature of water is not immutable, it will change with seasons, regions, environment, human processing and other factors.
All kinds of running water
Fast-flowing water: fast-flowing water. Because it has the characteristics of rapid diarrhea, it is often used to decoct and take wind medicine to facilitate defecation and treat below the shin. It is said that some people are sick and can't urinate, and many doctors can't cure them. However, Zhang only changed the water of decocting medicine into running water, which was used to decoct medicine, and achieved miraculous results with the help of running water.
Shunting the water: the nature is downstream, which is similar to that of flushing, so it is often used to decoct and take the syndrome of treating lower jiao, waist and knees and facilitating defecation.
Thousands of miles of water: that is, long flowing water that flows eastward, also known as east flowing water. Refers to elders in places where water flows, especially rivers. Starting from its birthplace, the river flows down the river and into the sea, but its sex is only bad. Zeqi decoction in synopsis of the golden chamber is decocted with east running water to treat upper-qi cough and take its implication. Because of its downward trend, it can also be used to decoct and take drugs for treating limb diseases and diuresis and laxative. If there is no river water, it can also be replaced by river water, such as Weihe River water.
Counter-current water: water returned during the flow. The ancients thought that its nature was reversed and its function was more upward than downward, so it was often used to decoct and spit.
Bantianhe
Half-day river water is the water in an empty tree hole or diabolo pipe. In short, as long as it is hollow in bamboo and wood and does not touch the ground, it can be called upper pool water, which the ancients thought was aura. Legend has it that after drinking the water from the upper pool, Bian Que had the super power to see the viscera, so he became an imperial doctor. The true story of medicine thinks that it is clean from the sky and not polluted by filth, so it is mostly used to refine and adjust Dan medicine.
Rain Water
Rain, that is, the rain that "the weather drops to rain" as mentioned in Neijing, does not seem to include snow, hail and other things that fall in nature. Compendium of Materia Medica holds that rain is salty, flat and non-toxic. According to different seasons, it can be divided into early spring rain, plum rain and liquid rain.
Rain in beginning of spring: Its nature begins with the rise and germination of spring qi, and it can develop everything. It is mostly used for those who have insufficient qi in frying and the clear qi does not rise.
Liquid rain: rain when liquid. After beginning of winter 10 day, liquid enters and xiaoxue leaves. The rain that falls between the entrance and exit of liquid is called liquid rain. The ancients believed that the reason why hundreds of insects crouched was directly related to the fact that hundreds of insects drank rain. After drinking the rain, all insects dormant, until the next spring thunder began to sting people. Therefore, liquid rain has the power to make hundreds of insects crouch, so liquid rain is often used to decoct insecticidal and digestion-promoting drugs to help the efficacy.
dew
Dew is a small drop of water attached to plants. When there is a lot of dew in autumn, you can put it on a plate. In the eyes of the ancients, dew is a wonderful product with great health care value, so sages often collect dew for later use, or use it for making tea, making wine, or treating diseases.
There are many kinds of dew introduced in Compendium of Materia Medica, such as flower dew, grass dew in autumn, and cypress dew, each of which moves with physical properties and has different functions. Such as dew on flowers, the color is very good; Dew on cypress leaves has the effect of improving eyesight.
Autumn dew in dew is collected when there is much dew in autumn. At this time, autumn dew is astringent and cold, and it is often used to decoct and take drugs that moisten the lungs and kill special diseases.
Newly melted snow
It is called wax snow (water) in Symptomatic Materia Medica and Compendium of Materia Medica, probably because wax snow is generally collected instead of Chun Xue. According to China's calendar, the third day from winter to the future is generally called the twelfth lunar month, which is the twelfth lunar month. According to this, wax snow (water) is the snow water melted by snowfall in December of the lunar calendar. According to "Compendium of Materia Medica", wax snow (water) has a special function: "When five kinds of grains are soaked in water, they are drought-resistant and do not produce insects; Spread a few seats, and the flies will leave, and the fruits will be drowned, so they will not eat. "
As for the taste of wax snow (water), Compendium of Materia Medica considers it sweet, cool and nontoxic, while Compendium of Materia Medica calls it sweet and cold. Therefore, wax snow (water) belongs to yin and is a cold product, which is used to decoct medicine to treat typhoid fire.
Wells springs
Seisensui is not a combination of well water and spring water, just well water. The water pumped first in the morning is called well flower water, and its essence floats on the water every day, so it is used to decoct medicine and nourish yin. It can also be decocted to take drugs for treating phlegm-fire and regulating qi and blood. The Fenggan decoction in "Golden Whip Grass" is decocted with well water to treat wind-induced symptoms in adults and convulsions and carbuncle in children, aiming at helping drugs to clear away heat.
Olive water
Ganlan water, also known as labor water, flood and sweet water. The preparation of Ganlan water is troublesome, and the water in the container needs to be lifted thousands of times with a spoon or spoon, and it is when there are many small drops of water in the container. The ancients thought that the original nature of water was salty and heavy, and after the lifting of the ban, the nature of water would change and become sweet and light, so decocting medicine with such water had special effects. The True Story of Medicine holds that Ganlan water can be used to decoct medicine and treat typhoid and yin syndrome. Poria, Cinnamomum cassia twig, Glycyrrhiza uralensis Fisch and Zizyphus jujuba decoction in Synopsis of the Golden Chamber treat sweating and palpitation under the umbilicus, which is a syndrome of typhoid fever and yin-yang deficiency and water movement. This prescription uses Ganlan water to decoct the medicine, which means that it is beneficial to the spleen and stomach instead of helping kidney qi.
In addition, the "Banxia Xiaomi Decoction" in Lingshu Xie Ke treats the syndrome of "Yang is abundant outside, Yin is insufficient, and Yang does not enter Yin". Decoct the medicine with Ganlan water to harmonize yin and yang.
Liaoshui
"Compendium of Materia Medica, Ministry of Water": "It is called poor shower, and it is called poor shower." That is, the running water on the road surface or the rainwater accumulated in low-lying areas after heavy rain or long-term rainfall. It is called a medicine for regulating spleen and stomach, eliminating dampness and clearing heat. Treatise on Febrile Diseases Mahuang Forsythia Chixiaodou Decoction is used to treat the symptoms of typhoid fever with blood stasis and yellow body. The decoction is made of water, which shows that it is light in taste and does not help damp heat.
The flowing water in Medicine True Story, also called rootless water, refers to the uninhabited land in the valley and the water in Xintuke Cave. Because of its unshakable nature, it has a simple memory, so it is mostly used to cook drugs that tonify the middle-qi and regulate the spleen and stomach.
Bai Fei soup
Boiling soup, also known as hot soup, Taihe soup and hemp boiling soup, refers to boiling hot water, and it is better to boil it than to boil it, hence the name.
In Treatise on Febrile Diseases, Dahuang Huanglian Xiexin Decoction is used to treat heart distension, press it, and close the symptoms of floating pulse. Ma Feng Decoction is used to dye the three yellows, which means that deficiency heat is relieved by thin qi. In addition, the Fuzi Xiexin Decoction in Treatise on Febrile Diseases, which is used to treat heat distension and yang deficiency, also uses Ma Feng Decoction to dye Sanhuang Decoction, and its intention is similar to the former.
In fact, the water used by the ancients for decocting medicine was by no means limited to the above, and there are still many things that have not been discussed, such as spring water, slurry water, solar water and so on. These waters may have special functions, but their detailed mechanism has not been clarified. Under the influence of traditional thinking, the ancients gave
