Infants and children suffering from constipation are caused by heat pathogens in the zang-fu organs invading the large intestine. The spleen and stomach are the sea of water and grain; the essence of water and grain transforms into blood, (and if heat is excessive, it consumes body fluids) leading to dry stool.
