In the Neijing, it is said that “the ancient people, who knew the law of yin and yang, and in the arts and figures …… so that the form and the gods, and the end of its natural life, degree of 100 years is gone” (Suwen – Shanggu Tianzhen theory). The actual body is dependent on the nourishment and warmth of the essence, and the kidney essence is the basis of the body’s essence, so one of the key points of health care lies in nourishing the kidneys. So, how to nourish the kidneys in accordance with the laws of heaven and earth to choose the appropriate method of health? A, the law of yin and Yang, in line with the time to nurture the kidney “Nei Jing” said “the kidney is the main dormant, the essence of the seal” (Su Wen – six sections of the Tibetan Elephant Theory), introduced the two characteristics of the kidney: one is “static and not delusional movement. Excessive exercise, ideas, thoughts, spicy and thick food, and work are all things that are delusional, which are not conducive to hiding the essence and nourishing the kidneys; secondly, “it is better to hide than to diarrhea”. Therefore, the key to nourishing the kidneys lies in the “tonic-based”, to protect the kidney essence, kidney energy. 1, in line with the season kidney “Nei Jing” said “in March, this is closed, water ice chap, no disturbance to the Yang, sleep early and late, must wait for daylight, so that the will if the ambush if hidden, if there is a private intention, if you have got, to cold on the temperature, no drainage of the skin, so that the gas is taken, this winter gas should be, the way to nourish Tibet.” (Suwen – Four Qi Tuning Shen Da Lun) This is to comply with the winter gas, the maintenance of the body’s closed function of the law. In addition, the winter solstice tonic is also a good way to nourish the kidneys in accordance with the four seasons. 2, along with the age of the kidney woman “seven years old, kidney gas, teeth more hair long. Two seven and the day sebum to, any vein through, Taichong vein Sheng, menstruation to the time, so there are children.” Men “eight years old, kidney energy, long hair and teeth. At the age of eight, the kidney energy is strong, the heavenly sebum arrives, the essence overflows and diarrhea, and the yin and yang are in harmony, so they can have children.” This is equivalent to “life is ten years old, the five Tibetan is set, the blood has been opened, its qi in the lower, so good walking.” (Ling Shu – Tian Nian) The kidney qi of a child comes from the kidney essence of the parents. If the child is stunted, with late teeth, thinning hair, late walking, late talking, urine loss, late menstruation, delayed thinking, unsound emotional development, as well as hyperactivity in children, then the child is deficient in kidney qi and needs to be treated from the kidneys. The woman “three sevens, the average of the kidney energy, so the real teeth and long pole. The fourth seven, the tendons and bones are firm, the hair is long and strong, and the body is strong.” In men, “the third eight, the average kidney energy, tendons and bones are strong, so the real teeth are born and grow. Forty-eight, tendons and bones are strong, muscles full of strength.” This is equivalent to “twenty years old, the blood begins to flourish, the muscle is long, so good tendency. Thirty years old, the five Tibetan great fixed, strong muscles, blood veins full, so good step. At this stage, kidney energy is most abundant. In order to maintain health and prolong life, it is also necessary to exercise restraint, so that the kidney energy can be maintained as sufficient as possible. At this stage, you should be disciplined in your living, not to overwork yourself, and not to overexert your body. In women, the Yang Ming pulse declines in the fifth and seventh year, the face begins to scorch and the hair begins to fall. Men “five eight, kidney qi decay, hair fall teeth haggard.” This is equivalent to “forty years old, the five Tibetan six provinces twelve meridians, are great to calm, the coup began to be divided, the glory declined, the hair is quite white, flat Sheng does not shake, so good to sit.” In addition, the “Nei Jing” also said “year forty, and Yin Qi since half also, living declined” (“Su Wen – Yin and Yang should be like the great theory”). This is the stage when the body’s kidney energy is in its prime and declines. In order to maintain health and prolong life, you should use some medicine and food, gongfu, in order to sufficient kidney energy. The woman “six or seven, three Yang pulse decay in the upper, the face are scorched, hair begins to white. Seventy-seven, the Ren vein is deficient, the Tai Chong vein is weak and less, the heavenly sap is exhausted, the earthly channel is not accessible, so the form is bad and childless.” Men “six or eight, Yang Qi exhaustion in the upper, face scorched, hair and temples issued white. Seven or eight, liver failure, tendons can not move, the sky is exhausted, less essence, kidney collection failure, the shape of the body are extremely. Eighty-eight, then the teeth and hair to go.” This is equivalent to “fifty years old, the liver begins to decline, the liver leaves begin to thin, the bile begins to extinguish, the eyes begin to be unclear. Sixty years old, the heart begins to decline, bitterness and sadness, blood slack, so good sleep. At the age of seventy, the spleen qi is weak and the skin is withered. At the age of eighty, the lung qi decreases, and the spirit leaves, so the speech is good and wrong. At the age of ninety, the kidney Qi is scorched, and the four Tibetan meridians are empty. Hundred years old, the five Tibetan are deficient, the gods are gone, the body alone and end.” This period of kidney energy gradually weak, resulting in other internal organs deficiency. Should pay extra attention to the use of medicine and food to replenish the kidney qi, to prevent excessive decline. Second, and in the art, all methods to nourish the kidney 1, medicine and food to nourish the kidney ① If the waist and knees are sore and weak, fatigue, accompanied by premature aging, forgetfulness, insomnia, vision loss, hearing attenuation, hair loss and gray hair, premature graying of the beard, teeth loose and easy to fall, etc., should be supplemented kidney qi. If the waist and knees are sore and weak, fatigue and weakness, accompanied by irritability, dizziness, tinnitus, insomnia, night sweats, etc., then the kidney yin should be tonified. Food tonic with wolfberry, black sesame, black beans, black rice, black fungus, kelp, seaweed, nori, black bone chicken, etc.; medicinal tonic with lily, wolfberry, mulberry, turtle plate, turtle nail, dendrobium, saxifrage, maitake, etc.; commonly used formula for the six flavors of Dihuang Wan; ③ if the waist and knees are sore and weak, and also see the fear of cold, spontaneous sweating, drowsiness, etc., then should supplement the kidney Yang. Food supplement with mutton, dog meat, prawns, etc.; medicinal supplement with deer antler, cistanches, eucommia, puzzle nut, locking Yang, purple river carp, cordyceps, etc.; commonly used formula is Jin Kuan Qi Pill. 2, massage for kidney rubbing Yongquan point is a common method of kidney. “Nei Jing” that: Chung Quan point is the acupuncture point of the foot Shao Yin kidney meridian, is located at the bottom of the foot, about when the plantar 2, 3 metatarsal toe crease head end and heel line of the first 1/3 and 2/3 intersection. Massage methods: ① push the spring, that is, with the thumb side of the toe push. Rub Yongquan, with the end of the finger to rub; ② rub Yongquan, with the palm of the hand close to the heart of the foot, quickly rub the hand until it is hot. 3, swallowing saliva kidney method was first seen in the “Nei Jing”. The “Nei Jing” said “five organs into liquid …… kidney for saliva” (“Su Wen – Xuan Ming five gas chapter”), “Su Wen – stabbing method theory” mentioned: “kidney has a long time disease, can c time facing south, quiet mind not chaotic thinking, closed gas seven times, to lead the neck pharyngeal gas smooth. To lead the neck pharyngeal gas smooth, such as swallowing very hard things, so seven times after, bait the tongue to make numerous Jin.” Swallowing saliva can be taken from the sitting and lying position, calm the mind and quiet breath after knocking on the teeth, followed by stirring the tongue, not swallowed after the production of fluid, and then drum gargle, the mouth fluid in three times swallowed, swallowed with the intention of guiding the fluid slowly to the lower Dantian, from little to much. This method can benefit the kidneys and consolidate the essence, induce the fluid on the tide, strengthen the spleen and benefit the qi, and nourish the yin and soften the liver. Conclusion: This is the end of the introduction of the five internal organs of the Nei Jing. I hope that through the understanding of the five organs, we can further understand the Nei Jing, Chinese medicine and traditional Chinese culture, and better health care and wellness.
