Miao medicine (bone marrow and bone injury ointment) has a long history of inheritance and has strong Miao medicine characteristics and Miao cultural characteristics. It is mainly spread in various Miao villages in Xiasi Town and Xuanwei Town in Majiang County, and has a history of more than 120 years. The Miao medicine (bone marrow and bone injury ointment) spread in the Long family of Xiasi Huilong is the ancestral secret recipe of the family. Since the Long family is a martial arts family, they usually like to practice martial arts. Long Zaiwen, the founder of the bone marrow and bone injury ointment, encountered muscle fractures and injuries in his daily life and martial arts practice, and then looked for medicine for treatment himself. He created a paste refining technology that uses 15 medicines such as rock horse mulberry, blood-flying, and bone-penetrating incense, which are dried, crushed, high-temperature, filtered, and then soaked for "seven seven forty-nine days". The formula and production process of bone marrow and bone injury ointment are unique. Combining the medical culture of Miao Township and the unique Miao folk external treatment method, it implements fumigation therapy, plaster application, acupoint application, etc., which belong to the method of external treatment of internal diseases, which is called "taking medicine for the skin" by Miao doctors. In addition to being suitable for rheumatism, fractures, muscle and bone pain, and bruises, it also has a certain effect on chronic diseases such as skin and cardiovascular diseases. Because the ointment is safe, effective, simple and inexpensive, it has been recognized and praised by the general public. On May 24, 2021, it was approved by the State Council to be included in the fifth batch of national intangible cultural heritage representative expansion project list.
