The jagged appearance of the edge of the tongue is mainly due to spleen deficiency and dampness obstruction and qi deficiency. The details are as follows: 1. Spleen deficiency and dampness obstruction: The jagged edges of the tongue appear because the “spleen” can regulate the blood, manipulate the transportation of water and dampness, and avoid the accumulation of dampness. Therefore, the physiological condition of the spleen can be reflected on the tongue. If there are teeth marks around the tongue, it means that the spleen is deficient in dampness. 2. Qi deficiency: the patient’s qi and blood are weak, due to the consumption of chronic diseases in the body, the qi and blood are weak, the operation of water and fluid is impaired, and edema occurs, resulting in a jagged tongue and a pale white tongue. The main manifestations are loss of appetite and mental weakness. Weakness of the limbs and drowsiness appear. The jagged edges of the tongue are mainly due to spleen deficiency and dampness obstruction and qi deficiency. Patients are advised to undergo standardized treatment as early as possible to minimize the adverse effects. If there are any uncomfortable symptoms, please go to the regular hospital in time to use medication under the guidance of professional physicians, so as not to delay the condition.
