The five internal organs of the human body are regarded as five active phenomena of lung gold, heart fire, liver wood, kidney water and spleen soil.
Take lung "gold" as an example: lung governs qi, that is, wind is energy, and gold can transfer heat (energy), absorb heat (energy), dissipate heat (energy), inhale and exhale air containing moisture, and evaporate water vapor. In winter, we can see that the exhaled white water vapor is hot, which is the residual heat (energy) generated by the lung being heated by heart fire and evaporating water vapor into heat (energy). The lung governs the fur, which is the surface layer of the whole body skin. The pores of the skin also have the functions of breathing, perspiration, heat dissipation, heat absorption and heat transfer. Sweating in summer is the same as the moisture dissipated by breathing. Sweating more, kidney urine less, sweating less and urine more in winter, regulating body temperature, absorbing heat, dissipating heat and transferring heat, so that the temperature rises and falls to "gold".
Fire can be divided into two types: ignition and phase fire, and fire is heat (energy). The sun in nature is a fire, the internal heat of the earth is a fire, the heart is a fire, the yang in the kidney is a fire, and the fire is spread by gold. Nutritional cremation produces heat (energy), the heart governs blood, and the heart governs whole body heat. When the heart beats faster, the lungs will breathe air faster. When the wind stops, the heat generated by the fire will be exhausted.
Wood is the source of fire and liver is wood. The liver governs the meridians and protects the blood, so that the blood can have ditches (blood vessels) to follow and will not be submerged by heat (energy). As the saying goes, "Liver blood lies flat and belongs to the liver (that is, the liver is charged)". After waking up, the liver blood is continuously supplied to the heart, and the heart vitality (fire), the liver supplies the heart blood, and the liver blood is exhausted. Hepatitis B can't be congested because the liver is poisoned by cold chemicals and blocked by cold, and blood can't be attributed to the liver, so the liver has no blood to supply the heart (fire). Therefore, people are always exhausted and prone to lie down. When they wake up, their mouths are bitter and dry, their lungs absorb heat, and the heat generated by heart fire dissipates too quickly, which is enough to accelerate the exhaustion of liver and blood, leading to the failure of liver-based meridians to protect blood circulation due to wind and cold, aching bones and muscles, and even cramping. "Is to make a fire for firewood, and Jin Kemu.
Kidney is dirty water. Chinese medicine tonifies kidney and strengthens yang, which is the vitality of life. The kidney is the beginning of life. Tonifying the kidney is the source of life, that is, tonifying the whole body. Tonifying yang is the energy to enhance life. Both men and women can tonify kidney and strengthen yang, not male penis in a narrow sense.
