Jie qi(subseasonal phases or solar qi)constitutes the solar component of the ancient Chinese lunisolar calendar. It divides the year into twenty-four subseasonal phases i.e. li chun(beginning of spring),chun fen(spring equinox),etc.From the premodern perspective of Traditional Chinese Medicine(TCM),normal climate change(qi hou bian qian)moves in harmony with the temporal flow of the qi(qi yun)and is thus beneficial to human health.However,abnormal,abrupt weather or climatic changes like those weather features of being too cold or too hot,too windy,too humid,too dry or a combination of two or more of these weather/climatic features which occur out of season can lead to’seasonal diseases’(shi bing)or ’diseases brought about by external influences’(wai gan zhi bing)or by the’six excessive climatic qi etiological factors’(liu yin zhi bing 六因致病).Some examples of seasonal diseases are SARS,influenza,the common cold and heat stroke. But the temporal flow of the subseasonal qi(qi yun) in Australia is the reverse of that of the northern hemispherical regions of China,United States and Europe.This situation thus leads to a temporal desynchronisation of TCM practice and practitioners with the rhythm of the seasons.In order to address this problem,I have constructed a Chinese Medical & Agricultural Lunisolar Calendar (Northern & Southern Hemispheres),which’reverses’the flow of the subseasonal phases in the southern hemisphere.Having this calendrical tool,Chinese medicine practitioners in Australia can’reverse’their clinical activities in accordance with the natural rhythm of the seasons here.
