1. odor is the main basis for judging the properties of drugs.
Here, gas and taste are discussed separately, and gas can be understood as the smell smelled by the nose; Taste is the taste in the mouth, and the nose should be divided between the upper and lower parts of the mouth. Traditional Chinese medicine believes that the nose absorbs the clear gas from the sky, which belongs to yang, and the mouth tastes the valley of the earth, which belongs to yin. Therefore, Neijing said that "the nose is connected with the weather and the mouth is connected with the earth."
Qi is yang and taste is yin ~ Huangdi Neijing
Drugs with strong smell mostly belong to yang, rising and floating and diverging, entering the exterior, yang meridian and six fu organs, and are warm or slightly cold in nature. For drugs with heavy taste, they will settle and converge to the interior, return to the Yin meridian and return to the five internal organs. The medicine is cold or slightly warm. Drugs with strong smell can be lifted and introduced from the outside to the inside. Drugs with a lighter smell are frivolous, but they don't keep it. When qi contains yin and yang, it is turbid to clear Huang Yuanyu.
1. Qi belongs to Yang, and Yang takes the initiative.
(1) has a soft and fragrant smell and thin qi, belonging to yang, which can act on the upper part of the body surface, rising, floating and dispersing to drive away evil spirits. Most drugs are slightly cold or hot, such as Schizonepeta tenuifolia, Saposhnikovia divaricata, Notopterygium root, chrysanthemum, dried tangerine peel, Bupleurum root and so on.
Drugs that act on the body surface enter the lungs because the lungs control fur, and drugs that disperse have the effect of stopping diarrhea and entering the liver.
(2) The smell is dirty and the gas is strong, which belongs to the yin of yang and can be used for the lower body. How cold or hot is the medicine? For example, rhubarb, aloe, aconite and cinnamon have a pungent smell and enter the lower jiao Wenyang.
Drugs act on the body, because the spleen and kidney are heaven, and more of them enter the spleen and kidney.
Thin gas leads to diarrhea, thick gas leads to fever ~ Huangdi Neijing
(3) pungent people disperse channels and stimulate yang, such as ginger relieving exterior syndrome and asarum dredging collaterals;
Sweet taste, such as roasted astragalus root, fried atractylodes and fried lentils, can benefit qi, strengthen spleen and regulate stomach.
The new stem diverges into yang
Sour people have astringent taste, and Cornus officinalis, Schisandra chinensis and pomegranate peel can all converge.
Bitter taste is overflowing, such as coptis chinensis.

2. The taste belongs to yin, and yin dominates quietness.
① The taste belongs to yin, and the five flavors match the five elements. If the taste is spicy, it can reduce the endowment of gold gas. For example, ginger can stop vomiting, and mint can soothe the liver through spicy gold wood.
Sour taste enters the liver to control the temperature rise. For example, Cornus officinalis warms the liver and refreshes the mind.
Bitter drugs enter the heart, control fire, are slightly bitter, belong to the nature of heart fire, rise due to fire inflammation, and are warm and dry, such as Epimedium, Cynomorium songaricum and Saposhnikovia divaricata; If the bitter taste is extremely severe, everything will be upside down, but it will sink into the water, such as coptis root and gentian root. Evodia rutaecarpa tastes bitter, pungent and positive. Although it has adverse effects, it is mild in nature.
The taste is sweet into the spleen and stomach of the middle energizer, and the soil is rich and nourishing, which can rise or fall. For example, astragalus membranaceus, a small amount of cultivation, a large number of health.
Every medicine is used to take its qi, its taste, its shape, or its essence. Xu ling fetus.

(4) Flowers, leaves and other light-weight drugs are mostly ascending, floating and dispersing, which are mainly transported by Yang, acting on the fur on the body surface and entering the lung meridian, and are warm or slightly cold in nature. Such as ephedra, duckweed, Schizonepeta, Saposhnikovia divaricata, perilla leaf, chrysanthemum and mulberry leaf.
The leaves of perilla frutescens are purple, and the branches and leaves are empty, just like the guard gas moves in the sun during the day and in the shade at night. Leaves can sweat, and sweat will be cleared. Zhang Zhicong
⑤ Those with heavier texture tend to lower yang and qi, and their medicinal properties are yin-cold, such as ochre, magnet and oyster.
⑥ The medicinal part is rhizome, which needs to nourish the branches and leaves on the ground. Most of them are upward movement forces, mainly nourishing and dispersing, such as the warm cultivation of Radix Astragali and the dispersing of Notopterygii Rhizoma.
⑦ The medicinal part is the seed, which is easy to fall off when the melon is ripe, and the force is mostly downward, which has the effect of reducing qi, resolving phlegm and converging. For example, perilla frutescens, white mustard seed and morning glory can reduce qi, while Rosa laevigata and Astragalus membranaceus can converge kidney qi.
Summary: Ancient physicians comprehensively analyzed each medicine with qi, taste, shape and quality, and combined with application experience to determine the nature, taste and efficacy of traditional Chinese medicine. Drugs are often used for many purposes.
