First, look 1, look at the shape The shape looks obese, but has not reached the standard of obesity, only overweight; muscle touch firm, flexible action, most of them are calm, damp heat, phlegm damp physique, qi deficiency is not obvious. If very lethargic, action dragging, walking dragging, the whole person seems heavy and tired, most of such people are phlegm and damp between the Yang deficiency or Qi deficiency body. The body is thin, the weight is not up to standard, and the subcutaneous fat is low, basically a deficiency physique. If thin and muscle flabby, yellow face, speak as if wandering, low voice, mainly qi deficiency physique. If lean and sturdy, flexible, good energy, usually Yin deficiency internal heat constitution. If the body is dry and thin, the face is dark in the mouth and lips, the skin is dry, and the tongue is purple and dark, blood stasis is the main quality. 2, look at the face color Chinese people are yellow, the normal face color should be yellow and lustrous, through a little blood color. Of course, there are shades of skin color, whether fair or dark, there should be luster. A shriveled face, i.e. yellow without luster and without blood, is a blood deficiency. Yellow and greasy skin is mostly damp heat. Dark face and lips, dark circles under the eyes before menstruation or when cold or insomnia often appear, are mostly blood stasis. If the face is white and lacks blood color and luster, it is Yang deficiency. 3. Look at the tongue. A fat, light and tender tongue with soft texture indicates a deficient constitution, and Yang deficiency and Qi deficiency are common. If the tongue is fat and very red, it is a hot body with a strong appetite. Feeling that the tongue is obviously swollen, the tip of the tongue is red and ruddy, and it seems to bite the tongue when eating, it means that one has eaten too much hot stuff or eaten too much and is prone to mouth sores. A thin, small, pale and shriveled tongue is a deficiency of qi and blood. A small, but red tongue with little tongue coating is Yin deficiency or internal heat. A purple and dark tongue, or petechiae and petechiae, is Blood stasis. The tongue often has teeth marks on the edges, which is Qi deficiency. A tongue that is often thick and does not easily recede is either damp-heat or phlegm-damp. If there is no tongue coating, it is yin deficiency. 4. Look at the eyes The eyes are shining, which may be on the side of heat constitution or calm constitution. A dull eye is a deficiency constitution, where Qi deficiency, Blood deficiency, and Yang deficiency can occur. Fatty deposits on the eye sclera, or very fine blood filaments that look cloudy all year round, are mostly seen in blood stasis, phlegm-damp and damp-heat constitutions. There is a more specific type of Yang deficiency constitution with upper heat and lower cold, which will also see cloudy eyes. 5, look at the nails The crescent is the white, rounded shape at the base of the fingernails. A normal crescent should be milky white, and the whiter it is, the healthier it is. A normal crescent accounts for about 1/5 of the entire nail cover. If it is less than 1/5, it means there is cold in the body; if it is more than 1/5, it means there is heat in the body. The thumb and middle finger should have crescent teeth, which means our body is moderately hot and cold and will not have major health problems. If there are no crescents on all 10 fingers and they have not been there since childhood, it means that the body is cold; if there was before and now there is not, it means that the body is heavy with cold. When the body is hot, 10 fingers have crescent teeth, there are more than 7 crescent teeth belong to the hot or hot body. Second, smell 1, listen to the sound of light and shallow voice, no mid-air, is a deficiency of Qi. The sound of the bottom of the air is sufficient, the gas is sufficient, usually phlegm and damp or calm body. 2, smell often sweat, body odor is particularly large, is phlegm damp or damp-heat physique. Often have breath, indicating that there is internal heat, stagnation. People with phlegm dampness, damp-heat, yin deficiency internal heat, upper heat and lower cold are prone to bad breath. If you are afraid of cold, tolerate summer but not winter, have cold hands and feet all year round, especially in winter when your hands are colder than your elbows and your feet are colder than your knees, cannot sleep under a hot blanket, and suffer from chronic illnesses that flare up or worsen whenever you are cold, you can basically be judged to have a Yang deficiency constitution. Those who are afraid of heat, tolerate winter but not summer, have warm extremities, especially in summer when the palms and feet are hot, and like to blow the air conditioner and drink cold drinks, have a hot constitution. Some people, especially women, are afraid of cold in winter and heat in summer, and are intolerant of cold and heat; they wear a lot of clothes when they are cold and drink cold drinks and blow air conditioners when they are hot, so they have poor adaptability to the climate. Commonly seen in qi-depression physique and qi-vacuity physique. Women with blood deficiency will also be afraid of cold, cold hands and feet, but usually accompanied by dizziness, palpitations, dreamy, yellowish face, menstrual volume and pale blood deficiency performance. 2, ask sweat Less sweat or no sweat, energy metabolism will be slow and not smooth, smothered inside, internal production of phlegm and dampness, depression and heat, damp heat. Too much sweating, such as sweating during the day without activity (spontaneous sweating), sweating at night after going to sleep (night sweating) are not normal, seen in Qi deficiency, Yin deficiency constitution. People who sweat little or no sweat and can eat are often inevitably obese, while people who sweat spontaneously or night sweat, have poor appetite and small meals will suffer from weight loss, insomnia, forgetfulness, and panic. Exercise, hot food, hot drinks, when the day is hot, than others obviously sweat less person, usually seen in qi depression, damp heat, phlegm damp physique, less sweat without sweat will be easy to fat, swelling, amenorrhea, irritability, acne, etc.. Because of the low energy consumption, poor metabolism of water and fluid, internal heat cannot be dispersed. Fourth, cut The pulse is strong and neatly paced, indicating good health, or at least good heart and lung function. If you can’t feel the pulse for half a day, it’s hard to feel it, but it feels very thin, if anything, it’s a deficient body; if the pulse is thin and the appetite is good, you will easily gain weight. A pulse that resembles a straight string is called the string pulse, also called the liver pulse, which means that the liver is not functioning properly. In a calm state, a quicker pulse is heat (actual heat or deficiency heat); a significantly slower pulse is Yang deficiency.
