title: [Liu Wansu's "theory of pathogenesis of six climatic qi" and its inheritance and development by Zhang Yuansu].
abstract: By using the "Six climatic Qi"-wind, heat, fire, dampness, dryness, and cold-to classify diseases, to mark the innate property of viscerae, and by using the theory of engendering-restraining-overwhelming-rebellion of the six climatic Qi and its conversion to elucidate the new theme of "extreme hyperactivity might conversely overcoming the Qi it is to be converted", and expound the specificity that fire-heat is apt to combine and assimilate with wind, dampness, and dryness. Liu Wansu proposed a complete "Theory of Six Climatic Qi for Mechanism of Diseases". By inheriting the main points of Liu's such theory, Zhang Yuansu studied the theory of prescription and medication in accordance with the "Six climatic Qi cause diseases" and classified prescriptions and medicines on the basis of "Six climatic Qi", thus, developed Liu's such theory as the guideline for syndrome differential diagnosis to directly handle clinical practice. In the meantime, he also promoted the theory of visceral syndrome differential diagnosis, embodying the mutual complementary property of theories for syndrome differentiation by both viscera and six climatic Qi.
