Spleen-Yang deficiency is a common clinical condition in Chinese medicine. At present, Chinese patent medicines commonly used in clinical treatment include Li-Zhong Pills and Li-Zhong Pills with Conjugated Zi. Lizhong Pill is commonly used as a warming and dispersing agent, which has the effect of warming the middle and dispersing the cold (dispersing the cold by warming the spleen and stomach), strengthening the spleen and nourishing the stomach, and can be used in the treatment of vomiting, diarrhea, abdominal fullness, abdominal pain, dyspepsia and other discomforts due to coldness in the spleen and stomach. However, this medicine is not suitable for people with diarrhea accompanied by abdominal heat and distension, people with cold and fever, and pregnant women. Radix Rehmanniae Pill also belongs to the category of warming and dispersing agents, and can be used for the treatment of cold pain in the epigastrium (cold pain in the stomach and abdomen), vomiting and diarrhea, and lack of warmth in the hands and feet caused by coldness in the spleen and stomach. However, to ensure the safety of the medicine, it is generally not suitable for people with cold and fever, pregnant and lactating women, and people with serious chronic diseases. Lizhong Pills and Radix Rehmanniae Pills, as commonly used medicines for spleen and stomach disorders, may have drug interactions if taken together with other medicines. Therefore, to ensure the safety of medication for patients, it is best to consult with a professional physician and then follow the doctor’s instructions.
