1. The spleen transmits the essence, which is transmitted to the eyes. The spleen is responsible for transporting water and grain, which is the source of biochemical energy and blood. Su Wen. Yu Ji Zhen Organs” in discussing the deficiency of the spleen, said: “If it is not enough, it is not enough, and it is not enough to make nine orifices.” It contains the idea that spleen deficiency can cause eye disease. Li Dongyuan’s “The Secret Collection of the Orchid Room. Eye, ear and nose door” further elaborated: “The essence of the five viscera and six bowels are endowed with the spleen, and the upper penetrates the eyes. Spleen deficiency is the essence of the five organs are displaced Division, can not return to the eye.” This highlights the relationship that the eye depends on the essence of the spleen for nourishment. 2. The spleen governs the blood and the blood nourishes the eyes. Miscellaneous evidence. Blood evidence” said: “cover the spleen blood, spleen deficiency is unable to collect; spleen blood, spleen deficiency is unable to transport, are no master, and therefore off the delusion.” From this can be seen, the blood is running in the eyes and not overflowing, but also depends on the spleen’s control. If the Spleen Qi is weak and loses its ability to regulate, it can cause bleeding in the eyes. 3. The spleen is the master of the muscles and the lids can open and close. The treatise on impotence says: “The spleen is the master of the muscles of the body.” The spleen transports the essence of water and grain to produce and nourish the muscles. When the lid muscles are nourished, they open and close freely. 4. The relationship between the eye and the stomach The spleen and the stomach are the mainstay of the postnatal period, as the internal organs are in harmony with each other. The stomach is the sea of water and grain, which receives and cooks water and grain and transmits it down to the small intestine, where its essence is transported and transformed by the spleen to feed the body. Therefore, Li Dong Yuan’s “Treatise on the Spleen and Stomach. Spleen and stomach deficiencies and changes, said: “the nine orifices, the five main organs, the five organs have stomach gas to be able to pass.” It is also pointed out that “if the stomach is deficient, the ears, eyes, mouth and nose will all be diseased.” This shows the importance of stomach qi in the eyes. In addition, the Su Wen. Yin and Yang Ying Xiang Da Lun says: “Clear Yang comes out of the upper orifice, and turbid Yin comes out of the lower orifice.” The spleen and stomach are the pivot of the body’s lift and entry, the spleen is the main ascending and descending of the clear, the stomach is the main descending and descending of the turbid.
