周正祎

Zhou Zhengyi is an author whose writing centers on clinical medication and diagnostic experience in traditional Chinese medicine. Public information about him is limited, and his nationality, dates of birth and death, and lineage have not been clearly recorded. Judging from the nine works held in the collection, he practiced medicine at the grassroots level for many years and, under the theme of "a grassroots veteran TCM doctor of 55 years," organized more than half a century of clinical experience into books. His works cover topics such as herbal identification and verification, the diagnosis and treatment of stubborn illnesses, repeatedly tested and effective formulas, simple, inexpensive and verifiable remedies, and easy herbal formulas. They include analyses of the properties and functions of medicinals, discussions of treatment approaches for chronic and difficult diseases, and a large number of effective small formulas suitable for grassroots use. His writing is documentary and reflective, plain in language and practical in emphasis, making it suitable for TCM clinicians and enthusiasts when studying formulas and materia medica or consulting treatment methods.
