Each of our 5 seasons, also has an element, a time of day, an organ system, a color, a direction, a sound, a flavor, and even an odor. We are entering the Spring season and the element that rules spring is Wood. The organs related to the wood element are the liver and the gallbladder. These 2 organs have very complex functions. The liver is known to have hundreds of functions in our body, and, it is likely that we will never know all of its functions. The liver is one of our largest organs and one of its main functions is detoxification. Spring is one of the best times to do a detox protocol.
