TCM inspection is one of the unique diagnostic methods of TCM, and the tongue coating inspection is the essence of the inspection method. Traditional Chinese medicine believes that thick white tongue coating with bad breath is one of the manifestations of food accumulation in the gastrointestinal tract. Because tongue coating can directly reflect the function of the zang fu organs. If the digestive function of the spleen and stomach is disordered, especially if the stomach function is disordered leading to the digestive function of the stomach and intestines, it will form accumulated food. Too much accumulated food will lead to bad breath, and the decaying stomach qi will rise to damp, resulting in thick and white tongue coating. In traditional Chinese medicine, Baohe Pill, Xiaoshi Jianwei Tablet and other Chinese patent medicines are commonly used to treat the thick white tongue coating and halitosis caused by food accumulation. Although these Chinese patent medicines only play a role in the gastrointestinal tract, they can only be used under the guidance of traditional Chinese medicine practitioners.
