Cough variant asthma (CVA) is a common clinical disease, and the current diagnosis and treatment process lacks the application of time view. The concept of time in traditional medicine reflects the entirety and syndrome differentiation, which has positive significance for the diagnosis and treatment of CVA. By reading literature and searching ancient books, CVA was understood again from the perspective of time concept, and the methods of diagnosis and treatment were explored. This paper discusses the development and change of time concept in medical field from slash and burn era to gene and molecular era. The characteristics of CVA and the time in the pathological process were discussed, and the application of time view in modern diagnosis and treatment was discussed. The time characteristics of CVA syndromes, zangfu organs and meridians were discussed and analyzed, and the combination of syndrome differentiation and time differentiation was expanded. This paper summarizes the time problems in the collection, preparation, decoction and taking of traditional Chinese medicine, and puts forward the necessity of using CVA decoction at the right time. The multi-directional discussion around the time view enriches the field of diagnosis and treatment of CVA. This paper introduces the time acupuncture (Ziwu Liuzhu) for cough, and an experimental case of CVA treated with Najia acupuncture.
