White moss on the tongue with teeth marks is usually caused by spleen deficiency and dampness, which can be regulated by medicines, such as Ginseng Ling Bai Zhu San and Liu Jun Zi Pill. However, the specific cause and medication should be decided by the doctor according to the patient’s other symptoms. 1. Ginseng Ling and Atractylodes Macrocephalae: It has the effect of tonifying the spleen and stomach and benefiting the lungs and qi. It can be used for the weak spleen and stomach, resulting in loose stools, shortness of breath, cough, tiredness and fatigue. Avoid indigestible food. Not suitable for patients with cold and fever. 2. Liu Jun Zi Pill: It is effective in tonifying the spleen, benefiting the vital energy, drying dampness and resolving phlegm (removing phlegm in the body with dampness-drying drugs). It is used for weak spleen and stomach, resulting in poor food intake, deficiency of qi and phlegm, abdominal distension and loose stools. Not recommended for pregnant women. If there is a need for medication, it should be used under the guidance of a traditional Chinese medicine practitioner to identify the symptoms, and should not be used blindly on its own to avoid adverse consequences.
