Currently there is no research to show that dry ginger has the function of protecting the gastric mucosa, but if patients with gastric mucosa abnormalities meet the indications of dry ginger, under the exclusion of contraindications to the use of medication, it can be taken under the guidance of a physician to assist in the treatment of dry ginger. Dried ginger is hot and pungent in nature, belonging to spleen, stomach, heart and lung meridians. It has the efficacy of warming the middle and dispersing cold (dispersing cold evils by warming the spleen and stomach), returning yang and clearing the veins, warming the lungs and transforming drinks (promoting the operation of stagnant water and liquid by warming the lungs), and is used for cold pain in epigastrium and abdomen (cold and painful sensations in the stomach, epigastric and abdominal regions), vomiting and diarrhea. Note that it should not be taken by those with Yin deficiency and internal heat, or those with blood heat. In addition to being used alone, dry ginger can also be used in combination with other medicines, for example, when treating cold pain in the epigastrium and abdomen, vomiting and diarrhea caused by deficiency of cold in the spleen and stomach (spleen and stomach are weak and cold), it can be used with Radix et Rhizoma Atractylodis Macrocephalae and Rhizoma Atractylodis Macrocephalae; when treating syncopal syndrome (unconsciousness, accompanied by icy cold in the limbs, even to the elbows and above the knees), and weak and desperate pulse, it can be used with Radix Scrophulariae, caused by deficiency of yang in heart and kidneys, and yin and cold within the heart and kidneys. It is recommended that patients with abnormal gastric mucosa should consult the hospital and standardize the treatment under the guidance of physicians.
