Dried ginger can be decocted according to the conventional decoction method, i.e., boil the medicine over a high heat, switch to a gentle heat and continue to decoct for 15 minutes to 20 minutes, then sop up the soup and let it cool naturally to the right temperature before taking it. Dried ginger is pungent in flavor and hot in nature. It belongs to the spleen, stomach, kidney, heart and lung meridians. It has the effects of warming the middle and dispersing cold (dispersing cold evils by warming the spleen and stomach with medicines), returning yang to the veins, warming the lungs and resolving drinks (facilitating the flow of stagnant water and fluid by warming the lungs). It is used for cold pain in the epigastrium (feeling cold pain in the stomach and abdomen), vomiting and diarrhea, cold limbs with weak pulse, and wheezing and coughing with cold drinks. It should be noted that it is forbidden to be taken by people with Yin deficiency, internal heat or blood heat. If discomfort occurs, one should consult a doctor in time to avoid self-treatment, which may affect one’s health. If you need to take dry ginger, it is recommended to do so under the guidance of a doctor.
