The traditional pharmaceutical skills of Mayinglong originated in Dingzhou, Hebei during the Wanli period of the Ming Dynasty. After 14 generations of inheritance, it has a history of more than 400 years. At the beginning, the founder Ma Jintang devoted himself to research and explored and summarized a unique set of pharmaceutical skills to make eye drops. After the development of the Qing Dynasty and the Republic of China, when the People's Republic of China was founded, Ma Huimin, the 13th generation descendant of Mayinglong, served as the director of Mayinglong Pharmaceutical Factory (later renamed "Wuhan Third Pharmaceutical Factory"). Based on the ancient prescriptions and prescriptions, he followed the traditional pharmaceutical skills and produced a variety of medicines such as eye drops and hemorrhoid medicines. In 1995, Wuhan Third Pharmaceutical Factory was renamed "Mayinglong Pharmaceutical Co., Ltd.", and Mayinglong's traditional pharmaceutical skills were continued to be preserved and promoted. Mayinglong's pharmaceutical skills have their traditional characteristics and norms. From material selection, preparation, ingredients to finished medicines, there is a set of strict regulations, which is unique. The materials selected are only genuine and excellent, and inferior and fake are avoided, and the medicinal materials used are very precious. In the process of making medicine, the hygiene of the utensils, the order of the raw materials, and the fineness and color of the medicines must be strictly controlled. Due to the different climates of spring, summer, autumn and winter, the methods of preparing raw materials are different, and there are strict requirements for the storage of medicines. The containers used are of different textures and types. Mayinglong's traditional pharmaceutical skills are kept absolutely confidential to the outside world. Within the family, they are only passed down to the eldest son and grandson, or passed down by merit. This has never been violated for hundreds of years. Mayinglong's traditional pharmaceutical skills have complex processes and delicate procedures. They can be regarded as the representative of my country's traditional Chinese medicine production technology. They have unique historical and cultural value, scientific development value and practical value. Modern production technology has brought huge challenges to the traditional pharmaceutical technology of handicraft workshops, resulting in the loss of traditional technology, which should be taken seriously.
