The spleen and stomach are not the origin of the innate. The innate essence is the kidney, and the spleen is the acquired essence.
The kidneys are the origin of the innate, and they have the physiological function of harboring essence, which is the basic substance that constitutes and maintains the body’s development, growth, and functions in various activities. The essence stored in the kidneys consists of the innate essence and the acquired essence. The prevalence of essence in the kidneys determines the reproduction, development and growth of the human body. The innate essence stored in the kidneys is the material basis for the kidneys to become the innate essence.
The spleen is the foundation of the acquired nature, which means that after birth, a person relies on the receptive (acceptance) and transporting functions of the spleen and stomach to produce blood and vitality, regulate qi, and glorify and nourish the whole body. Physiologically, the spleen is the main transporter, which can transport and transform water, grain and fluid. If the water and grains can be digested and absorbed properly, the human body can obtain sufficient nutrients to maintain the normal life activities of the organism.
If you have any spleen or stomach discomfort, it is recommended that you go to a regular medical institution in time.
