For a thick white tongue with cracks and teeth marks, you can take Chinese medicines such as Xiangsha Liu Jun Zi Pill and Ginseng Strengthening the Spleen Pill. Cracked tongue, known as cracked tongue in Chinese medicine, is generally regarded as heatiness or blood deficiency without moisturizing, and spleen deficiency without nourishment. The presence of teeth marks is considered to be a sign of spleen deficiency or internalized water-dampness (water-dampness stays in the body). White and thick tongue coating is usually the main internal evidence, phlegm-dampness. Therefore, a white, thick tongue with cracks and teeth marks is mostly due to a deficiency of the spleen, which leads to the accumulation of water-dampness. 1. Ginseng Pill for Strengthening the Spleen: It has the effect of strengthening the spleen, benefiting the vital energy, harmonizing the stomach and stopping diarrhea. It is used for treating weak spleen and stomach resulting in dietary inactivity, stuffy and noisy epigastrium (stomach feeling similar to hunger, emptiness with burning), nausea and vomiting, abdominal pain and loose stools (thin and unshaped feces), etc. Note that those with phlegm-dampness, yin-deficiency and fire-exuberance (Yin-essence deficiency in the body, with hyperactivity of deficiency and fire), and liver-qi stagnation (poor transportation of qi and blood in the liver and depression), etc. are not recommended to take it. 2. Xiangsha Liu Jun Zi Pill: It is effective in benefiting qi and strengthening the spleen (regulating the qi of the spleen and stomach), resolving phlegm and harmonizing the stomach. It is used for treating spleen deficiency and qi stagnation, indigestion, belching (hiccups) with little food, distension of the epigastrium (abdomen), and loose stools, etc. However, it should be noted that it is not recommended for people with internal heat in Yin deficiency. If you feel unwell, please consult a doctor in time. Proprietary Chinese medicines need to be used after diagnosis, and should not be used on their own, so as not to delay the best period of treatment of the disease.
