In Chinese medicine, every organ has its functions or “responsibilities” . These are not all physical, they are psychological and spiritual as well. The heart has special importance in TCM as it is seen to be the “ruler” of all the other organs, and when the body is healthy and balanced, it is a kind and benevolent leader.
