Chinese Medicine was created during a period when people were  living more in alignment with nature.  Our bodies were seen as a reflection of nature and the elements were used to describe the qualities of how our bodies function. The five elements of Traditional Chinese Medicine are wood, fire, earth, metal and water. Each of these  systems have  a  time of day, time of year, emotion, tastes and sense organ.
