Spleen and stomach deficiency and cold (spleen and stomach weakness and cold) with dry mouth and astringency can be improved by taking Chinese medicines (Dingkou Lizhong Pills, Xiao Jianzhong Tablets, etc.), and it is recommended to use medicines under the guidance of a professional physician. According to Chinese medicine theory, the spleen and stomach are located in the middle jiao, which is the hub of water and liquid operation. If the spleen and stomach are deficient and weak in transportation, there will be obstacles in the transmission of water and liquid in the body, and the fluids can not be carried upwards, thus resulting in the situation of dry mouth and tongue, and if there is a combination of cold and cold blockage, cold stagnation, and a further lack of fluids operation, then it will exacerbate the feeling of dryness and astringency of the mouth. Dingkou Lizhong Pill has the effect of warming the middle and dispersing cold (dispersing cold evils with medicine that warms the spleen and stomach), tonifying the spleen and strengthening the stomach, and is good for treating cold pain in the epigastric region (cold pain in the stomach and epigastric region), vomiting, diarrhea, indigestion and other conditions. Attention, pregnant women, diabetic patients, people with cold and fever should not take. Xiao Jian Zhong Tablet has the effect of warming the middle and tonifying the deficiency, relieving acute pain (relieving urgent pain symptoms), and is good for treating cold pain in the abdomen, acid reflux and noisy (stomach feeling similar to hunger, emptiness with burning), and loss of appetite. Note that it is contraindicated for people with vomiting, abdominal distension, and burning pain in the stomach and epigastrium. It is recommended that patients with dry mouth and astringent mouth with cold spleen and stomach should go to the hospital in time, and use the medicine under the guidance of professional Chinese medicine practitioners.
