The Five Element Theory is a system that organizes all natural phenomena into five major groups or patterns in nature. Each of the five groups—Wood, Fire, Earth, Metal, and Water—include categories such as a season, direction, stage of growth and development, internal organ, body tissue, emotion, taste, color, sound, and much more. In regards to organs and their relationship to health, each element is “responsible” for the functions of the body. This means that if an organ is unhealthy, it is common to see all of its responsibilities suffer at the same time or in sequence. For example, people are often siblings to others, employees to companies, parents to their children, and children to their parents. If they get severely sick, all of those relationships will be impacted at the same time.
