In ancient times, people pursued the concept of “attacking poison with poison”, believing that although medicine and food were found in the same way, food and medicine were two completely different concepts that did not intersect, and food could not be used as medicine, and medicine could not be turned into food. When it was recorded in the Rites of Zhou, court doctors began to appear, and one of them was the “food doctor”, a nutritionist in the court. “, from then on, the first food treatment of disease. Where does medicine come from: this is how food therapy originated Traditional medicine has a well-known saying called “medicine and food have the same origin”, that is, drugs and food have a common origin. In ancient times, people in the process of looking for food, occasionally found a certain food after eating, the body pain relief, or the original disease somehow cured, may be a tribe of many people eat this kind of food have found it has the mysterious power, slowly, the tribe of people with pain again, will go to find this food to eat, try more people, they will also find that this food is only for the body to eat, try more people. They will also find that this food only has a good pain relief effect on abdominal pain, no significant effect on headaches, trauma, this time, in order to facilitate the identification and communication between the tribe, they gave this food a special name, the tribe’s respected elders to its role, the treatment of which ailments are recorded one by one, passed on to future generations, it became a kind of herbal medicine. The Huainanzi records that in ancient times Shennong “tasted the taste of a hundred herbs, the sweetness and bitterness of water and springs, so that the people knew what to avoid. When this time, a day and encountered seventy poison”. This “poison” does not mean poison, if Shennong could taste seventy kinds of poison a day, he would not have the life to achieve the great work of “making the people know what to avoid”, so in the ancient times, “poison” and “medicine Therefore, in the ancient times, “poison” and “medicine” is not divided, so this passage means that Shennong found seventy kinds of drugs a day, this seventy is also a false number, Shennong is after all different from mortals, he is the founder of the farming society, the legend says that in ancient times, the white turtle carrying the river map, Rui Ma (dragon horse) carrying the Luoshu respectively from This book was interpreted by Tai Hao Fuxi’s, created the eight trigrams, created the text, determine the four seasons of spring, summer, autumn and winter, Tai Hao Emperor (Fuxi’s) died, Shennong’s inheritance of the world on the emperor’s throne, that is, Emperor Yan. The emperor marched between the mountains and the wilderness every day, eating and sleeping in the open air, tasting all the grasses and springs in the mountains, summarizing the parts of them that were therapeutic and suitable for the survival of the ancient people, and teaching the world to avoid the parts that are harmful to the body, and the word “on” means close, and the “on “In this process, various kinds of medicines were discovered. In ancient China, there is a book called “Shennong Ben Cao Jing”, which is the earliest extant work on materia medica. This book was not written by Shennong, but later people borrowed his name in order to commemorate this ancestor who taught medicine to the people, just as “Huang Di Nei Jing” was not written by Huang Di, but was written by later generations of medical doctors together.
