China is the country with the earliest origin of pedicure. China recorded about foot massage thousands of years ago. According to research, pedicure and acupuncture are "the same root and the same origin" therapies in China. ? People have four roots, namely, nasal root, milk root, ear root and foot root. "The nose is the root of Miao Qiao, the milk is the root of the ancestral spirit, the ear is the root of the magical machine, and it is the root of the essence." It can be seen that the nose, ears and milk are only the condensation points of essence, while the feet are the total collection points of essence. Clinical observation, clear mind and light and healthy steps are all characteristics of health; And top-heavy, feet edema, walking difficulties, for the sick body. Therefore, all the health and fitness methods at home and abroad attach great importance to foot exercise. A man with feet is like a tree with roots. When a tree dies, the roots are exhausted first, and the old feet are old first. Feet play an important role in health care. Experts believe that the principle of foot massage mainly has the following four aspects: First, the theory of blood circulation. The feet are at the bottom of the human body, and harmful substances such as uric acid crystals in the blood are deposited on the soles of the feet, which is not good for the health. Through foot massage, harmful substances deposited on the soles of feet can be decomposed and excreted through sweat and urine. The second is the reflection principle. "Foot is the second heart of human beings", and there is a one-to-one correspondence between human viscera and plantar acupoints. Foot massage promotes the brain to transmit signals through the reflex zone, improves human endocrine and blood circulation, and regulates the physiological environment. The third is the principle of holographic theory. Traditional Chinese medicine regards the whole as a part and the foot as a holographic embryo of the human body, which is full of information of the internal organs. Foot massage is a massage for the whole body. Fourthly, the scientific principle of meridians in TCM, namely, the theory of three Yin San yang in TCM. Foot massage can stimulate and regulate viscera, dredge meridians and enhance metabolism through foot massage, so as to achieve the purpose of strengthening the body and eliminating diseases and pathogens. Judging from the meridian theory of traditional Chinese medicine with a history of more than two thousand years, it can better explain the close relationship between feet and the whole body. According to the meridian theory, the foot is closely connected with the viscera of the whole body through the meridian system, which constitutes the unity of the foot and the whole body. There are six meridians in the twelve meridians of human body, namely, Foot Three Yin Meridian and Foot Three Yang Meridian, which are distributed in the foot. Foot is the beginning of foot three yin meridians and the end of foot three yang meridians. These six meridians are connected with the Sanyang Meridian and Sanyin Meridian of the hand and run through the whole body. The Yinqiao pulse, Yangqiao pulse, Yin Wei pulse and impotence pulse of the eight odd meridians all originate from the foot, and the chong pulse branches from the foot, thus strengthening the connection between the foot and the tissues and organs of the whole body. Therefore, the changes of viscera function can be reflected in the feet. Pedicure is a non-drug therapy, which regulates the physiological function of human body and improves the function of immune system by stimulating the reflex zone of foot, so as to achieve the purposes of disease prevention, treatment, health care and physical fitness.
