What are the functions and indications of the four qis?

The four qi refer to the four different medicinal properties of the drug: cold, hot, warm and cool, also known as the four natures. Generally speaking, cold medicine has the functions of clearing heat and repurging fire, cooling blood and detoxifying, answering and nourishing yin and removing steam, laxative heat, clearing heat and diuretic, clearing phlegm and heat, clearing the heart and opening the body, cooling the liver and relieving wind, etc.; The warm medicine has the functions of dissipating cold in the warmth, warming the liver and dispersing knots, replenishing fire and helping yang, warming yang and benefiting water, warming meridians and channels, returning fire to its origin, and returning to yang to save adversity.

Cold medicine - clear away heat and relieve fire, cool blood and detoxify, nourish yin and remove steam, diarrheal heat and laxative, clear heat and diuretic, clear phlegm and heat, clear the heart and open the body, cool the liver and relieve wind.

Warm medicine - warm the cold, warm the liver and disperse knots, replenish fire and help yang, warm yang and water, warm meridians and channels, lead fire to the original, return to yang and save adversity.

Generally, clinical medication is to use both its qi and its taste, but sometimes when it is combined with other drugs, there may be different situations of using its qi or its taste. If cimicifuga is sweet and slightly cold, when it is used with astragalus to treat the depression of central qi, its sweet taste is taken to enhance the effect of yang qi; If it is used with Pueraria lobata to treat measles, take its pungent flavor to relieve the epidermal rash; If it is used with gypsum to treat stomach fire and toothache, take its cold nature to clear heat and reduce fire. This is the so-called "decoction of materia medica" by Wang Haogu

The medicine is pungent, sweet, sour, bitter, salty, and tasteful; Cold, hot, warm, cool, and airy. The taste is five, the gas is four, and among the five flavors, each flavor has four gases, there are those who make the qi, there are those who make the taste, and there are those who make the smell......It is also used in different ways. Therefore, it is necessary to be familiar with the general laws of the four qi and five flavors, and to master the special role of each drug odor and the law of odor coordination, so as to grasp the medicinal properties and guide clinical medication.

The four qi, also known as the four natures, refer to the four medicinal properties of cold, heat and temperature. Among them, the difference between cold and , heat and temperature is only the difference in degree, that is, temperature is second to heat and second to cold. That is, cold and temperature are the same nature, and heat and temperature are also the same nature.

Cold and warm are two opposing medicinal properties.

In addition, there are some flat drugs, whose cold and heat bias is not obvious, in fact, there are also differences in temperature bias, there is no absolute flatness, and it still does not exceed the range of the four sexes. Therefore, in essence, the four sexes are actually cold and hot.

The early cold and hot temperature of the drug is summarized from the reaction of the drug on the body, and corresponds to the cold and hot nature of the disease being treated. Drugs that can reduce or eliminate heat syndrome have cold or sexual properties, and generally have the effects of clearing heat, expelling fire, blood, and detoxifying. Drugs that can alleviate or eliminate cold syndrome are warm or hot, and generally have the effects of dissipating cold in warmth, replenishing fire and helping yang, warming meridians and pulses, and returning to yang to save adversity.

The historical origins of the four gases

The four qi were first recorded in the "Shennong's Materia Medica: Preface", which refers to the medicine "having cold, heat, warmth, and coolness". However, Kou Zongzao of the Song Dynasty believed that "whoever is called qi is fragrant and smelly, and its cold, hot, warm and cold are the properties of medicine." ......The word 'qi' in the preface ("Shennong's Materia Medica, Preface"), I am afraid that future generations will mistake the book, and it should be changed to the word "sex", which is allowed by Yifang.

It is proposed to change "qi" to "sex", so the "four qi" is also called "four sexes".

Li Shizhen of the Ming Dynasty.

It is believed that "Kou's words of cold, heat, warmth, and coolness are sexuality, and fragrance, smell, fishiness, and shame are gas, which is similar to the "Book of Rites".

Wenhe. But since "Su Q.

Since then, only the smell of the word, it is difficult to change the pawn, and it is easy to follow the old er", and it is still advisable to call it "qi".

The four aspects of cold, heat, warmth, and coolness in traditional Chinese medicine, or "qi" or "sexuality", are both ancient and modern, and coexist at the same time, all of which refer to the inherent laughter of drugs.

The above content reference: Encyclopedia - Four Qi (drugs have four different medicinal properties: cold, hot, warm and cool).

The four qi refer to the four different medicinal properties of the drug: cold, hot, warm and cool, also known as the four natures。Cold and warm are two opposing medicinal properties; Between cold and cool, between heat and temperature, there is a difference in degree, that is to say, the medicinal properties are the same, but there is a difference in degree, temperature is second to heat, and cold is second to cold.

Due to the procedural difference between cold and cold and hot temperature, it is also necessary to pay attention when using mu mold drugs. If you use warm medicine when you use hot medicine, and use cold medicine when you use cold medicine, you will not be able to achieve the purpose of ** disease; On the contrary, when warm medicine is used and hot medicine is used, it will hurt its beam slippery yin, and when cold medicine is used instead of cold medicine, it is easy to damage its yang.

Four gas divisionsOne is the five-point rule. Li Shizhen.

The classification of the five sexes is proposed, which is considered to be "five natures, cold, fast slag, slow heat, warm, cool, and flat".

The second is the quadrangle. "Shennong's Materia Medica".

It was proposed that medicine "has four qis: cold, heat, warmth, and coolness", and later generations followed it.

The third is the rule of thirds. The Tang Dynasty's "Six Books of the Tang Dynasty" put forward the "Three Natures Theory", saying that "the three natures are cold, warm and peaceful".

Fourth, dichotomy.

As far as specific drugs are concerned, there is still a difference between cold and heat, which belongs to the two sexes of cold and heat.

Siqi has many meanings in Chinese, and the common one refers to spring, summer, autumn and winter.

The four seasons; the four emotions of joy, anger, sorrow, and happiness; The most commonly used in traditional Chinese medicine refers to the fact that drugs have the properties of cold, hot, warm and cool, which is one of the important concepts that reflect the nature of the drug.

Words. 四气 (sì qì).

1.It refers to the heat, cold, and cold air of spring, summer, autumn and winter. 2.Han Confucianism attached to the corresponding saying of heaven and man, with joy, anger, joy and sorrow, and the four times are the four qi.

Chinese medicine. 1. Meaning: Also known as the four sexes, it refers to the fact that the drug has the properties of cold, hot, warm and cold, and it is one of the important concepts that reflects the nature of the drug.

Medicinal. Basis for determination: It is based on drug reaction and cold and heat as the benchmark.

1. Drugs that can alleviate or eliminate fever are generally cold or cold, such as gypsum and radix indigo.

2. Drugs that can alleviate or eliminate cold symptoms are generally hot or warm, such as aconite and dried ginger.

Efficacy. 1. Function: The four qi are only cold and hot in essence, and all cold drugs mean that they have the ability to clear heat, relieve fire, cool blood, and detoxify heat.

and other effects, where the warm medicine is used, it means that it has the effect of dissipating cold in the warmth, replenishing the fire and helping the yang, warming the meridians and channeling, and returning to the yang to save the adversity.

2. Adverse reactions.

The effect of the four qi on the human body has two sides, if it is not applied properly, the cold will hurt the yang and help the cold, and the warm will hurt the yin and help the fire.

Medicinal properties. Warm is yang, cold is yin. There are degrees of differences in the same nature, temperature is second to heat, and cold is second to cold.

The four qi refers to the four different medicinal properties of the drug: cold, hot, warm and cold, also known as the four natures. It reflects the tendency of drugs to act on the rise and fall of yin and yang, cold and heat changes in the human body, and is an important part of the theory of medicinal properties, and is one of the main theoretical bases for explaining the effect of drugs. What are the four qi that I have collated?

Welcome to it. The four qi refers to the four different medicinal properties of the drug: cold, hot, warm and cool. It is an important medicinal theory that corrects the rise and fall of yin and yang in the human body by regulating the cold and heat changes of the body, and is an important medicinal theory to explain the nature of the drug. For the four gases.

Cognition originated very early. "Han Shuyi Wenzhi Fang Technique" said: "The prescription, the cold temperature of the herbal stone, the shallow and deep of the disease, the taste of fake medicine, because of the sense of qi, distinguish the five hardships and six hardships, cause the Qi of water and fire, and untie the knot with opening and closing, and vice versa."

It can be known that the medicinal properties are divided into cold and temperature, not later than the Western Han Dynasty. The text also pointed out that the cold and heat of the medicinal properties are formed by "the appropriateness of the sense of qi", so the "Benjing" first proposes that "there are four kinds of cold, hot, warm and cool qi". It can be seen that the four qi of the earliest medicinal properties are summarized by the characteristics of the four seasons of climate.

However, in order to avoid confusion with the smell of medicine, Kou Zongzao of the Song Dynasty advocated changing the "four qi" to "four natures". Li Shizhen also said from it, saying that "Kou's words are cold, hot, warm and cold are sexual, and fragrant and smelly and fishy are gas, which is consistent with the text of "The Book of Rites". But since "Su Wen", only the smell of words, pawn can be changed, so from the old.

Although the arguments of Kou and Li are also reasonable, they fail to explain the original meaning of the four qis. The medicinal properties of the four qi are also the same as the five flavors, which have the attributes of yin and yang, that is, cold is yin, and warm is yang.

Cold and warm are two opposing medicinal properties, while the difference between cold and warm is only in degree, that is, "cold is second to cold" and "warm is second to hot". Some Materia Medica literature also describes the four characteristics of drugs with "great heat", "great cold", "slightly warm" and "slightly cool", which is a further distinction between the different degrees of the four qi of traditional Chinese medicine, and shows that it should be used at discretion. In addition, in addition to the four sexes, there is a class of flat**, which refers to a class of drugs with cold and heat properties that are not obvious, have peaceful medicinal properties, and have a milder effect.
