The Heart, according to Chinese medicine, is the king of all organs. This means that all the other organs always give their energy to help the Heart maintain its balance. The Hearts partner is the Small Intestine.
According to Five Element Theory, the heart is directly related to the liver and the stomach. the Liver is the “mother” of the Heart, the Stomach is the “child” of the Heart. The balance of Heart energy comes from the balance of Stomach energy. Continual stress causes Liver energy low because one of its energetic functions is to smooth and regulate emotions. So, the Liver cannot properly support the Heart when Liver Qi is deficient. To maintain healthy Heart function, it’s important to maintain balance of the Liver and the Stomach.
