The white coating in the middle of the tongue is caused by the loss of transportation of the spleen and stomach, the accumulation of phlegm-dampness or cold-dampness trapping the spleen, and the spleen-yang not rising.
1. The spleen is an organ and the stomach is a viscera, and the two have a relationship with each other. The stomach is the “sea of water and grains”, which can receive (accept to hold), putrefaction (initial digestion of food, the formation of food waste) of water and grains. The spleen has the functions of transportation, elevation and clearing, and blood control.
If the spleen and stomach can not accept and putrefaction of water and grain, the loss of transportation of water and grain essence, can not spread the limbs and bones, water and drink are easy to accumulate in the body, gather moisture for phlegm, so see the middle of the tongue with white thick tongue coating.
2. Due to cold diet, the middle jiao is obstructed, spleen yang is not elevated, the stomach is out of harmony (obstruction of the stomach’s function of ventilation and descending), the diet is not transformed, and the tongue is offended by the diet, so the middle of the tongue is white and thick.
The white and thick tongue coating in the middle of the tongue needs to be treated according to the theory of traditional Chinese medicine on the basis of the four diagnostic methods, and if there is any discomfort, it is recommended to consult a doctor in a timely manner and standardize the diagnosis and treatment under the doctor’s guidance, and not to be used on one’s own, so as to avoid affecting one’s health.
