Thousands of years ago, Taoists Chinese philosophers, began looking for ways to understand their health. They put together the Five Element Theory that is still used today in Oriental Medicine. Their studies included Taoist philosophies, the elements of Nature, changes of the seasons, and how these related to the changes with the body and personal health. Some of these included the types of emotions a person is prone to, food cravings, how one feels after eating, as well as how we interact with the seasons, both personal and social relationships. The Five Elements are: Earth, Metal, Water, Wood, and Fire. Each of these elements corresponds to a season, an emotion, body organ and surface part, attitude, mental and spirit trait, and taste.
