What are the treatment methods for thick white tongue coating with cracks in the middle?

The treatment methods for thick, white tongue coating with cracks in the center mainly include the following points: 1. Dietary adjustment: Patients should appropriately consume nutrient-rich foods such as red dates, beef, coix seed, kiwifruit, and apples. These foods help eliminate dampness from the body and thereby improve the condition of the tongue coating. 2. Medication adjustment: For patients with spleen deficiency and kidney insufficiency, traditional Chinese medicines such as Fuzi Lizhong Pills or Buzhong Yiqi Decoction may be used to strengthen the spleen and stomach, nourish the kidneys, and calm the mind, thus improving symptoms of thick, white, greasy tongue coating accompanied by cracks. For tongue coating issues caused by phlegm-dampness, if the tongue coating is white, greasy, and heavily cracked, this indicates cold-dampness, which can be treated with Shenling Baizhu Pills; if the main feature is a thick white coating, this suggests damp-heat, which may be addressed with Huanglian Qingwei Pills or Longdan Xiegan Pills to clear damp-heat. 3. Daily lifestyle adjustment: Patients should develop healthy living habits, including going to bed early and rising early, avoiding staying up late, maintaining appropriate indoor humidity and temperature, and avoiding excessively damp environments. Additionally, regular physical exercise should be encouraged to enhance the body's resistance to disease.
