Emotions, from Chinese Medicine perspective can be called a ‘pathogen’. Just as eating too much sugar can lead to an imbalance in the body, so too can the excess of any of the main emotions such as anger, joy, sadness or grief, worry, fear or fright.
Each emotion corresponds to an organ. When an organ’s energetics are out of balance, it can exacerbate the corresponding emotion. Likewise, if a person experiences a certain emotion too much, it can weaken the energetics and hence, functioning of that organ.
