Drooling is a physiological phenomenon if it occurs occasionally, but if it occurs frequently and to a serious extent, drooling is not necessarily caused by spleen deficiency, but may also be caused by dampness and heat in the spleen and stomach (the spleen and stomach feeling dampness and heat evil qi) or coldness in the spleen and stomach (the spleen and stomach being weak and cold). Drooling, also known as salivation (drooling), is most common in young children under the age of three. In infants, salivation occurs occasionally because their mouths are shallow and do not regulate excessive saliva in the mouth, which is a physiological phenomenon and not a pathology. If salivation occurs frequently and to a serious extent, it is a pathological condition. According to the viewpoint of traditional Chinese medicine, if the spleen and stomach are wet and hot, the dysfunction can’t regulate the saliva, so the saliva flows out of the mouth. Spleen and stomach cold, mostly due to over-served cold drugs or prolonged illness of the spleen and stomach cold, spleen deficiency can not collect fluid, so the saliva from the out. If you have any symptoms, you need to go to the hospital as soon as possible, the doctor according to the specific conditions, to develop individualized diagnosis and treatment plan, so as not to delay the condition.
