Thick white tongue coating in the middle is caused by phlegm (a pathological product formed by the impaired metabolism of water and fluid) and water and dampness gathering and stagnating in the middle jiao, which can be regulated by drinking Chinese medicines, and can also be treated by other methods such as acupuncture and moxibustion. Medicines such as Ginseng Ling Bai Zhu San and Bao He Pills can be used, and acupoints can be chosen such as the middle stomach and foot San Li. If the tongue is thick and white in the middle, and if there is excessive saliva in the mouth, dizziness in the head, discomfort in the epigastrium (abdomen), loose stools, etc., Ginseng Ling Bai Zhu San can be used to dispel water-dampness in the middle jiao to relieve the symptoms, and if there are also symptoms of indigestion and nausea, then the symptoms are considered to be oesophagogastric stagnation (the stagnation of indigested food in the stomach), and Bao He Pills can be taken to regulate the symptoms. Acupuncture and moxibustion can be applied to the middle epigastric region and points in the spleen and stomach meridians, such as the middle epigastric region, the foot Sanli, and the Sanyinjiao, to help the middle jiao to transport and transform the body and thus alleviate the symptoms. In case of discomfort, it is recommended to go to a regular hospital and take appropriate treatment according to the advice of a professional Chinese medicine doctor, rather than blindly operating on your own.
