Why is the plaster called dogskin plaster?

According to relevant historical records, in the early years of Chongzhen in the Ming Dynasty, Yao Benren, a native of Jiangxi Province, took the examination for entering Beijing because of his superb medical skills and was promoted to be a contemporary imperial doctor. Park 1644, Yao Benren retired in his later years, and began to set up Yiguang, and began to prepare plasters, and smeared black plasters on dog skin to make black plasters.

1. From a scientific point of view, dog skin is hot. Sticking the plaster on the dog skin is beneficial to the effective absorption of the plaster by human skin, which belongs to high-end and high-quality plaster products. Dog skin plaster is summarized by modern medicine as transdermal administration or transdermal sustained-release administration, and transdermal sustained-release technology has become a hot spot in medical research. In some developed countries in Europe, this mode of administration has become more and more mainstream.

2. Dog skin plaster belongs to the external dosage form of traditional Chinese medicine. Its main functions are expelling wind, removing dampness and relieving pain. It is mainly used for treating rheumatism, traumatic injury and muscle strain. Due to the tight source of dog skin, there are fewer and fewer plaster products on the market at present, and the backing of plaster has changed from dog skin to oil paper, canvas and so on.

Third, the gradual decrease of dog skin plasters on the market at present is not only related to the tight supply of dog skin, but also closely related to the tense pace of life in the new era. The use of dog skin plaster is troublesome, so it needs to be heated first, and then evenly applied after the medicine is dissolved. Except for the first time, dog skin plaster is also very easy to stain clothes and affect the appearance. In addition, the production process of dog skin plaster is complicated, so it gradually withdrew from the historical stage of plaster.
