Nausea and vomiting due to cold stomach can be treated by general treatment and medication. 1. General treatment: Cold invades the stomach, leading to the upward reversal of gastric qi (gastric qi rises instead of falls), and nausea and vomiting appear. In daily life, pay attention to keep warm, avoid eating cold and stimulating food, and focus on light and easy to digest. Ensure sufficient rest. 2. Medications: Cold stomach can be treated with Chinese medicines that have the effect of warming the middle and dispersing cold (using medicines to warm the spleen and stomach to disperse cold), such as Lizhong Pills. Lizhong Pill is composed of ginseng and dried ginger, which has the effect of warming the middle and dispelling cold, tonifying the qi and strengthening the spleen, and can be used to treat vomiting and other symptoms caused by coldness in the spleen and stomach. Lizhong Pill is contraindicated in cases of vomiting and diarrhea caused by damp-heat obstruction (accumulation of dampness and heat to form stasis). Adverse reactions are not clear. Patients in need of treatment should choose the appropriate program under the guidance of a doctor.
