In this episode we talk to Tyler Rowe, practitioner of Chinese medicine, martial arts and specialist in the practical application of classical Chinese geomancy and astronomy texts. We explore the relationship between climate and illness, and dive deeply into the often poorly understood Wuyun Liuqi (Five Movements and Six Qi) system from the Huangdi Neijing, discussing its history and practical usage in clinic. We also delve into how applications of the system, and Chinese medical theory in general, might differ in the Southern hemisphere, and possible relationships between the system and the current Covid-19 pandemic.
