Exploring the Concept of “Nourishing Yang in Spring and Summer, and Nourishing Yin in Autumn and Winter” from the Perspective of the Circular Movement of Yang Qi Ascending and Descending

Abstract

This article is based on Peng Ziyi’s theory of circular motion, and according to the characteristics of the descending, sinking, and rising of Yang Qi in the 24 solar terms, “Yang is nurtured in spring and summer, and Yin is nurtured in autumn and winter”. It can be summarized as the suitable warm and nourishing qi for wood and fire in spring and summer, as well as the clear and restrained qi for gold and water in autumn and winter. The central qi is like an axis, the four dimensions are like a wheel, and the warm and nourishing qi for the spleen and stomach runs through the entire four seasons. This theory is essentially the basic principle of regulating the body’s yang energy during the four seasons proposed within the framework of the academic theory of “the integration of human and heaven and earth”. According to the principle that when Yang Qi enters, it becomes real, and when Yang Qi exits, it becomes virtual. Its purpose is to correct deviations and restore roundness, in order to maintain the balance of yin and yang in the human body, and to guide people’s health preservation and pantient medicatian throughout the four seasons.
