The production, transportation and excretion of body fluid is a complex process, which comes from the digestion of diet through the stomach, the transportation of spleen and the spread of lung to the body surface and bladder. The kidney is an important organ in charge of the metabolism of water and fluid in the whole body, which raises the clear and lowers the turbid. In addition, body fluid is yin, which depends on Yang Qi's solid absorption and promotion.

In traditional health care in China, saliva is extremely precious and has the reputation of life-prolonging syrup. Saliva contains a variety of beneficial components, especially in promoting digestion and enhancing nutrition absorption function, which plays a great role. On the one hand, it can quench thirst, on the other hand, it can nourish people's lives. A healthy and energetic person has a lot of saliva in his mouth. I always feel thirsty and my throat is tight. There must be something wrong with my health.

Function of body fluid

1, moisturizing and nourishing

Body fluid is a liquid substance containing nutrition and has a strong moisturizing effect. Body fluid contains nutrients and has a rich nourishing effect. Moisturizing and nourishing complement each other and are inseparable. However, due to the thin texture of body fluid, its moisturizing effect is obvious, while the thick texture of liquid has obvious nourishing effect.

Body fluids scattered on the body surface can nourish fur and muscles, those infiltrated into the body can nourish viscera, those injected into orifices can nourish official orifices such as nose, eyes, mouth and ears, those injected into bones, spine and brain can nourish bone marrow, spinal cord and brain marrow, and those flowing into joints can nourish joint flexion and extension.

If the body fluid is insufficient and loses its moisturizing function, the physiological activities of fur, muscles, orifices, joints, viscera, bone marrow, spinal cord and brain marrow will be affected, and the physiological structure of viscera may also be destroyed.

Step 2 nourish blood vessels

Body fluids enter the pulse and become an important part of blood. It has been explained in Lingshu Xie Ke that body fluid, under the action of nourishing qi, penetrates into the veins and turns into blood, thus circulating the whole body and playing the role of moistening and nourishing.

Body fluids can also regulate blood concentration. When the blood concentration rises, body fluids penetrate into veins to dilute blood and replenish blood volume. When the body fluid is insufficient, the body fluid in the blood can ooze the pulse to supplement the body fluid.

Due to the mutual infiltration of body fluids inside and outside the pulse, the body can adjust the blood concentration according to physiological and pathological changes, maintain normal blood volume, and play a role in dredging blood vessels. Because both body fluid and blood are produced by subtle changes in Shui Gu, and they can permeate and transform each other, it is said that body fluid and blood are homologous.

In addition, the metabolism of body fluids can regulate body temperature to adapt to the temperature changes in the natural environment. When the climate is hot or the body is hot, body fluids are excreted in the form of sweat to dissipate heat. When the weather is cold or the body temperature is low, the body fluids do not leak out because of the blockage of acupoints, so that the body temperature remains relatively constant.
