According to legend, in China, during the period of the Chu-Han rivalry, Liu Bang, the ancestor of Han Gaozu, was fighting in Henan Yinsan and contracted the plague, which could not be cured for a long time. The local people offered a recipe for “ginger and radish soup”, and Liu Bang’s condition was greatly reduced after drinking it, and the medicine was removed after another drink. Ginger not only cured the emperor’s plague, but also saved many common people. During the Tang Dynasty, there was a monk named Xingduan in Chang’an Xiangji Temple, who went to the South Wutai Mountain at night to cut firewood and became mute after returning to the temple. Some said it was because the demon on the mountain had bewitched him; others said it was because they were afraid he would tell the truth about the mountain and make him mute. When the rumor spread, the monks were so scared that they no longer dared to go up the mountain to cut firewood. The abbot of Xiangji Temple hastily led the monks to do a sermon in front of the Buddha for 81 days, so that the Buddha could exorcise the demon for Xingduan, but to no avail, Xingduan still could not speak. At that time, a monk, De Shi, who knew a little bit about medicine, suggested that Xingduan should seek medical help from Liu Tao, who was an excellent doctor in Chang’an. He accompanied Xingduan to Chang’an and met with Liu Tao, a famous doctor, and explained in detail the cause of his illness. Liu Tao said after checking his face and pulse, “Master, go back first, I will go to the mountain tomorrow to see the prescription.” In the early morning of the next day, Liu Tao came to the mountain, and after careful observation, he came to Xiangji Temple with confidence, took out a piece of ginger from the medicine bag, and said to the abbot, “Don’t worry, please ask the sama to quickly decoct this medicine, and the medicine will be removed in three to five days.” Although the abbot had the ginger decocted for Xingduan, he always had doubts in his mind, so he intended to keep Liu Tao in the temple for a few more days to see the effect of the treatment. After two days, Xingduan took three doses of ginger soup, and the stagnation in his chest was gradually relieved, and his throat was easy and smooth. After taking three more doses, he was able to speak, and all the monks in the temple were surprised. The abbot inquired about the cause of Xingduan’s illness, and Liu Tao said, “This was caused by the sanyasin mistakenly eating half a summer in the mountain, and once the ginger was used, the medicine was removed, and it was not caused by any demon.” The monks also got rid of their heart disease and went to the mountain to cut firewood as usual.
