Tongue with teeth marks and cracks in the center can be regulated by taking Ginseng Ling Bai Zhu San as prescribed by the doctor. According to Chinese medicine practitioners, teeth marks on the tongue are related to spleen deficiency, because the spleen is the main transporter of water and dampness (the spleen has the function of digesting food, absorbing food essence and water and transferring it to the whole body), and if the spleen is deficient, it is unable to transporter water and dampness, which leads to hypertrophy of the tongue, and teeth marks will appear when the tongue is pressed by the teeth; cracks in the middle are related to the invasion of dampness by a deficiency of the spleen. Ginseng Ling Bai Zhu San has the effect of strengthening the spleen and stopping diarrhea, and is good at treating the evidence of spleen deficiency and dampness. The adverse reactions and contraindications of this drug are not clear, and should not be taken by patients with cold and fever; symptoms not relieved after 4 weeks of taking the drug should go to the hospital. After the discomfort should be timely medical treatment, under the guidance of the doctor to use medication, not self-medication.
