The common and old unified prescriptions were compiled as the Recipe Directory of 81 Kinds of Chinese Patent Medicines, making some changes, unification and compression, and supplemented with those missing in the original book. Recipe Directory of 81 Kinds of Chinese Patent Medicines has standardized the production and sales, established the basis for inspection, and was convenient for application.
