Five elements, namely wood, fire, earth, gold, water and their movement and changes. The "five" in the five elements refers to the five basic substances of wood, fire, earth, gold and water differentiated from the vitality of the universe. "Line" refers to the movement and change of these five substances.
The ancients summarized the characteristics of "soil" as soil and crops. "Hey" means "Yue"; "crops", that is, planting food; "Thirty" means harvesting grain. Farming refers to the agricultural activities in which human beings grow and harvest food. All things and phenomena with biochemical, bearing and receptive properties or functions belong to soil. There are four lines in the native land, everything is born in the soil, everything is destroyed in the soil, and the soil is the mother of everything.
Traditional Chinese medicine divides the attributes of things into five elements, among which "earth" is: five internal organs-spleen; Five internal organs-stomach; Five qi-wet; Five orifices-mouth; Five bodies-meat; Five aspirations-thinking; Five flavors-sweet; Five tones-palace; Five tones-songs; Five colors-yellow; Direction-medium; Biochemical-chemical; Summer with four distinct seasons; Change cards, etc.
"Earth" nourishes everything.
"Earth" occupies a special position in the five elements. The viscera corresponding to "earth" is the spleen, which is the source of qi and blood biochemistry, and its subtle Shui Gu is the source of nutrition needed to maintain life activities, providing sufficient nutrition for other organs, meridians, limbs, bones and muscles, so the corresponding season called "the foundation of the day after tomorrow" is long summer, which can be understood as the general term of seasonal changes. If it is interpreted as a collection of "Changchun, Long Summer, Long Autumn and Long Winter", it may be easier to understand. The seasons corresponding to soil are scattered among the four seasons, which proves on the other hand that soil is the most basic element in the five elements and has the power to nourish everything that other substances do not have. From another point of view, the "wet" of soil can also prove this view. The wind dominates in spring, which is a common clinical syndrome of exogenous rheumatism attached to wind evil; Summer is dominated by summer heat, which is not only hot but also humid. Summer evil is often mixed with wet evil to invade the human body. Although dryness and dampness are two opposite "qi" in autumn, it is difficult to exist, but it is not uncommon for dryness to hurt Yin points and dampness to stay inside, which is one of the more difficult diseases to treat. Winter is dominated by cold, and exogenous wind and cold, internal stagnation of water and dampness, spleen and stomach deficiency and endogenous dampness are also common in clinic. "Wet" gas runs through the four seasons and interacts with other four gases, which is also consistent with the property of "soil". In addition, the relationship between spleen and other viscera should be considered in the specific implementation of clinical syndrome differentiation and treatment. If the spleen is mainly transported, the blood metaplasia function is vigorous, the blood vessels are full, and the heart is in charge; Spleen's transport function is strong, Shui Gu's essence is sufficient, and the human body's ancestral spirit is strong, then the lung's main qi and respiratory function can be played normally; If the spleen does its duty and actively produces blood, the liver will be nourished; Kidney essence also needs Shui Gu's subtle nourishment and cultivation. Therefore, the treatment of other organs takes into account the regulation of spleen and soil.
