What are the Five Yu points? The upper limbs are below the elbow and the lower limbs are below the knee, and each meridian has five very important acupuncture points called Jing, Xin, Yu, Jing and He, so they are called the Five Yu points. (Xinxing, yinxing, Xing, the second sound, Shuowen Jiezi: Absolutely less water.) In ancient Chinese, the words acupoint, yu, and losu are commonly used, i.e., generic characters. In ancient Chinese medical classics, they are sometimes referred to as the Five Yu points, or the Five Acupoints, or the Five Losing Points. Most of these points are commonly used and effective in clinical practice (Ling Shu? The Five Yu points are mostly the more common and effective points in clinical practice (Ling Shu? The Five Acupuncture Points are mostly used and effective in clinical practice (Ling Shu?) Each of the twelve meridians has five specific points from the end of the extremities to the elbow or knee, called the “five acupoints”. This is the size of the water flow to describe the characteristics of each meridian qi from small to large, from shallow to deep. “The outflow is the well, the slip is the Xingying, the injection is the transmission, the line is the Jing, and the entry is the He, and all the twenty-seven qi flowing are in the five acupoints.” (Ling Shu? The nine needles and twelve original). This means that the qi and blood flow from the ends of the limbs upward to the head and torso, like water flowing from small to large, from shallow to deep. When the meridian qi first emerges, it is like the source of the water flow, so it is called “well”; when the meridian qi is a little stronger, it is like the micro-flow of water, so it is called “xing”; when the meridian qi is gradually stronger, it is like the infusion of water, so it is called “infusion”. It is called “Jing” because it is full, like the long flow of water; it is called “He” because it is abundant, like the convergence of water. Well: refers to the first underground spring, tiny and shallow. Yang Xuan Cao “difficult scripture” note: “valley, spring water first out of the place named well, well the main out of the meaning. Xingying: refers to the small water into a stream. Shuowen Jiezi”: “Xingying, the absolute small water also. Yang Shanshan “Mingtang” note: “water overflow for Xinxing, said twelve meridians from the point has been, flow overflow here, so named Xinxing.” The name Xinxing. The name Xingying refers to the flow of water that can be transported and filled. The “Shuowen Jiezi”: “Lose, also the committee lose. Yang Shanshan’s “Taisu” note: “Infusion, send to gather also. The Book of Difficulties? Eighty-one difficulties” said: “The five Tibetan transfusion is the place where the Sanjiao Qi stays. Therefore, the lung qi and the Sanjiao qi are sent to gather here, so it is called losing. Jing: refers to the water flowing through the straighter and longer. Erya? Interpretation of water”: “straight wave said Jing. Yang Shanshan “Tai Su” note: “Jing, often also. The water flowing, not stopping for constant. Blood gas flow injection here, Xu Xing not endless, for the constant. Hop: refers to the confluence of water into the deep. Yang Shanshan “Tai Su” note: “such as water out of the well to the sea for the healing, the pulse out of the finger well, to this merge in the original collection of Qi, so named healing. Each of the five acupuncture points has its own characteristics: Jing point: to open the body and awaken the mind, which can be used for mental confusion and boredom under the heart; Xinxing point: to clear the evil fire, which can be used for fever; Lv point: for episodic diseases and joint pain; Jing point: for asthma and throat diseases; He point: for the six internal organs, such as the intestines and stomach. Ling Shu? The “Shun Qi day is divided into four times,” which says: “If the disease is in the hide, take the well; if the disease is in the color, take the Xingying; if the disease is in the time, take the Lue; if the disease is in the sound, take the Jing; if the Jing is full of blood, the disease is in the stomach, and if the disease is caused by a poor diet, take the He.” The Supplementary Explanation of the Book of Difficulties? The explanation of the “Sixty-eight Difficulties”: “The well is for fullness under the heart, the Xin is for heat in the body, the Losing body is for pain in the heavy joints, the Jing is for wheezing and coughing, cold and heat, and the He is for rebellious qi and discharge.” Ling Shu? The form of the disease of the evil energy hiding house is summarized as follows: “Xinxu treats the outer meridians, and He treats the inner house.” This means that the Xingyi and Xuezhu points treat diseases of the meridians, and the Hefei points treat diseases of the six internal organs. The Nangjing also combines the five acupuncture points with the five elements, and on this basis, it proposes the method of “tonic mother and diarrhea”. The Ling Shu? The “Form of Disease in the Zangfu of Evil Qi” says: “Xinxing and Luo treat the external meridians, while the combined points treat the internal organs. According to Ling Shu? According to the “Spiritual Shushu?”, there are five acupuncture points for the five viscera, while the six internal organs have a special “original point” in addition to the five points. Therefore, they are also known as: well, Xingying, Infusion, Yuan, Jing, and He. In this way, the five organs have twenty-five acupuncture points. The six internal organs have thirty-six acupoints. Although the five organs do not have a special “original points”, the original points have the same function is “acupuncture points”. That is, the “acupoints” of the five organs, and the “original points” of the five organs. In short, the five points occupy an extremely important position in the theory of meridians, and should be pressed frequently in health care.
