Bitter mouth, dry throat and thick and greasy tongue coating are considered to be the result of liver qi stagnation caused by spleen and stomach disharmony and spleen qi deficiency, mostly as a result of spleen and stomach dysfunction. Especially in the morning, when there is bitterness in the mouth, this aspect is mostly considered as the cause. It is necessary to pay attention to the diet, mainly with light food. Secondly, we should give symptomatic treatment with medicines, such as Chinese medicines, such as qi stagnation and stomach pain granules, Pu Yuan and stomach capsules, Xiao Chai Hu granules, etc. Xiao Chai Hu granules can play a role in relaxing the liver and Qi, calming the spleen and stomach. For those who have frequent bitterness in the mouth and do not see relief from Chinese medicine, they also need to improve the H. pylori test. If you have H. pylori infection with DPM greater than 700, you need anti-H. pylori treatment and gastroscopy to assist in the diagnosis and treatment.
