Qi Bo said to him: Brain, marrow, bone, pulse, gallbladder and daughter cells are all born of the qi of the earth. They are all dirty in the yin and happy in the land, so they hide without diarrhea, so they are called Qi Hengfu.
Qi Bo replied: Brain, marrow, bone, pulse, gallbladder and daughter cells are all born from the qi of the earth, and they can store yin, just as the earth contains everything, so their function is to store essence, so they are called organs.
Original: the sum of heart and pulse, its glory and color, its main kidney. The combination of lung and skin, its glory and hair, its main heart. The combination of liver and muscle, its glory and claws, its main lung. The combination of spleen and meat, its glory and lips, its main liver. The combination of kidney and bone, its glory and hair, its main spleen.
The heart corresponds to the pulse, and its glory is manifested in the complexion, and kidney water can control the heart fire; The lung corresponds to the skin, and its brilliance is manifested in the hair, and the heart fire restricts the lung gold; The liver corresponds to the tendon, which is brilliant in claw nails and lung gold restricting the liver wood; Spleen corresponds to muscle, and its glory is manifested in lips and liver wood restricting spleen soil; Kidney corresponds to bone, and its glory is manifested in the restriction of kidney water by hair and spleen.
Therefore, if you eat more salty food, your pulse will change color due to tears; If you eat too much, your skin will wrinkle and your hair will pull out; If you eat more spicy food, your muscles will be anxious and your claws will dry up; Eat too much acid, the meat will be tender (moonlight) (Zhu Sisheng), and the lips will be exposed; If you eat more sweets, your bones will ache and you will feel weak. These five flavors are also hurt. So the heart is bitter, the lungs are pungent, the liver is sour, the spleen is sweet, and the kidney is salty. These five flavors are also harmonious.
Because of this, the salty taste of overeating makes blood vessels blocked and facial color changes. The bitter taste of overeating makes the skin wither and the hair fall off. Eating too much spicy food will make your muscles strong and your claws dry. Overeating and sour taste will make muscles thicken and contract, and lips become warped. Eating too much sweets will make your bones ache and your hair fall off.
This is the harm caused by the partial eclipse of five flavors. Therefore, the heart should be bitter, the lungs should be spicy, the liver should be sour, the spleen should be liver-flavored, and the kidney should be salty, which are the corresponding relationships between the five flavors and the qi of the five internal organs.
