Legend has it that a long time ago, there was a strange disease among the people. The patient was sallow and emaciated and bedridden until he died of asthma, cough and hemoptysis. For a time, thousands of households were deserted and villages and towns were left out. At that time, there was a beautiful and clever girl named Gillian in Weijiazhuang, Dong 'e County, Shandong Province. Her parents also suffered from this disease and both died. Gillian went to Mount Tai in Dongyue alone to find medicinal materials and relieve the pain for the villagers. One day, there was a crane in Lu Yu, which made an elderly person look young. My elders told me that the disease can be cured, but there is little medicine: I need the skin of a little black donkey. The donkey is fierce and abnormal. Ejiao thought of the villagers' illness and quickly grabbed the elders and said, I am willing to give my life as long as it can save people's suffering! Hearing this, the elder smiled and nodded, and Gillian immediately learned from the teacher. After 7749 days, I mastered 72 swordsmanship, that is, I bid farewell to my teacher and went to the mountains to find the little black donkey. After some efforts, Ejiao subdued the little black donkey, that is, boiled the donkey skin according to the instructions of the elders. Ejiao added 8864 tons of spring water to the pot and burned 998 1 ton of Sang Mu, which lasted 7749 days and nights. The shiny and delicious medicine glue is out of the pot. When the patient took a good one and wanted to thank the benefactor, the elders and Ejiao disappeared. People say that the elder came down to earth to be a medicine king bodhisattva and took Ejiao to Xianshan to be a medicine boy. In memory of this Ejiao girl, this medicinal glue was later called "Ejiao".
According to another legend, Cixi suffered from fetal leakage and bleeding when she was pregnant, and stopped from time to time. Although she has been treated by famous doctors many times, it is ineffective. Seeing that her condition is getting worse and worse, I'm afraid the fetus will be in danger. This worries Emperor Xianfeng, who has never had children. At this moment, Chen Zonggui, assistant minister of Shandong Dong 'e people's household department, told Xianfeng that Cixi would take Ejiao produced by Dong 'e Deng's Shudetang for treatment. Cixi listened to his advice and ate Ejiao. Sure enough, the blood stopped her illness and she gave birth to a baby boy at full term. This boy is the later Tongzhi emperor. Emperor Xianfeng gave the word "Fu" as the card of Shudetang, because he was grateful to Deng for his contribution to Ejiao. Since then, Ejiao with the brand of "Fu" has become a royal medicinal material of the court, which has gained great fame.
Chinese medicine believes that Ejiao is sweet and flat, and has the effects of nourishing yin, enriching blood and preventing miscarriage. According to research, Ejiao contains a variety of protein, amino acids, calcium, etc., which can improve the blood calcium balance and promote erythropoiesis. In addition, Ejiao can raise blood pressure and prevent hemorrhagic shock, and it also has a good preventive effect on progressive muscular dystrophy in animal experiments.
In traditional Chinese medicine, Ejiao is the best medicine in gynecology. Clinically, it is mostly used to treat women's fetal, menstrual and obstetric diseases and some internal medical diseases.
