Song Su Song said, "Use the five flavors of food to cure long-time illness and labor infection." Tao Hongjing of Liang used it to cure all fistulas. In the Song Dynasty, it was used in the Sheng Hui Fang to treat bone vapor and laboriousness. In Ming Dynasty, Li Shizhen used it to cure children's tuberculosis, and so on. Li Shizhen also quoted a story from the Book of Audit and Records of the Gods, which vividly illustrated the anti-TB effect of eel. He said that some people were infected with tuberculosis (tuberculosis, which was called labor infection in the ancient times) and infected each other, killing many people, so they took the sick people and dumped them by the riverside in order to eliminate the harm. When a fisherman saw her, she was a woman who was still alive, so he took her and put her in the fishing house and fed her with eels every day, so she gradually recovered and became the fisherman's wife. (Shen Kuo "Mengxi Brush Story" also contains this story).
