Buddhist medicine is the product of mutual influence and blending of Buddhist culture and traditional medical culture in China. Buddhist medicine is based on "medical prescription is clear" in ancient India, guided by Buddhist theory, absorbing and drawing lessons from the theory and clinical characteristics of traditional medicine in China, thus forming a unique traditional medical system. Buddhist doctors emphasize "both internal and external cultivation" and "physical and mental treatment", with the internal goal of treating the heart as the external goal. Taoist doctors were originally based on the theory of five elements. After the Tang Dynasty, Taoist medicine spread widely, evolved into Chinese medicine, and followed the five elements theory. Affected by this, Buddhist doctors also believe that nature can be closely linked with human life activities, forming a five-element structural system that links the internal and external environment of the human body to illustrate the unity of the human body and the natural environment. The earliest ancient medical classic Huangdi Neijing connected the internal and external environment of human body into a closely related whole.

Five aspects: southeast, middle, west, north and five elements: wood, fire, earth, gold and water, five flavors: sour, bitter, sweet and salty, five internal organs: liver, heart, spleen, lung and kidney, five senses: anger, joy, worry and fear, and five colors: blue, red, yellow and salty.

"Compendium of Materia Medica" mentioned: "Beans have five colors, each of which treats five internal organs, but black beans are colder than water and can enter the kidney." This is related to the concept of "Five Elements Keeping Healthy by Color" in Buddhist medicine. The concept of five elements closely links the five zang-organs, five senses, five prescriptions, five elements, five flavors and five colors, and holds that the interaction and mutual restriction between the five elements have a corresponding regulatory effect on the five zang-organs and their corresponding emotions. The theory of five elements emphasizes "shape and shape complement each other" and "color and color complement each other", and holds that black enters the kidney because black belongs to water and water belongs to the kidney; The shape of black beans is similar to that of kidneys, so black beans are called "Valley of Kidney". For example, black beans tonify kidney, mung beans tonify liver, red beans tonify heart, wheat tonify spleen and lily tonify lung. Buddhist doctors emphasize "preventive medicine", and what Buddhists and Bodhisattvas do is to prevent slow progress, eliminate diseases from "causes", and prevent diseases from blossoming and bearing fruit, resulting in bitter fruit. The theory of "preventing diseases" of Buddhist doctors is more perfect and thorough than that of traditional Chinese medicine. Both Buddhist doctors and Chinese medicine practitioners believe that diseases can be cured through the healing function of the human body. Buddhist medicine can be divided into "physical medicine" and "legal medicine". Physical medicine treats the body and legal medicine treats the heart. Ordinary Chinese medicine only pays attention to physical medicine, while Buddhist doctors put forward the idea of treating the heart on the basis of treating the body, so that people can heal themselves through "forensic medicine" The rituals, classics, laws and theories we see on weekdays are also common manifestations of forensic medicine.
