There is no such thing as the nemesis of stomach disease, Dendrobium powder. Dendrobium powder is effective in treating gastric yin deficiency (insufficient yin fluid in the stomach) syndrome, but it cannot treat all stomach diseases. Dendrobium powder has the effect of benefiting the stomach and generating fluids (nourishing the stomach by replenishing the fluids in the stomach), nourishing yin and clearing heat (nourishing the yin essence and clearing the heat). It is used for heat disease, dry mouth and thirst, lack of gastric yin, dry vomiting with little food, non-removal of deficiency heat after illness, yin deficiency and fire exuberance (deficiency of yin essence in the body, and hyperactive deficiency fire), bone vapor and labor heat, darkness of the eyes, and impotence of sinews and bones. Dendrobium powder is forbidden to be taken by those who have not injured the yin in the early stage of warm-heat disease, those who have not turned dry in wet-warm disease (warm disease caused by feeling dampness and heat), and those who have deficiency of spleen and stomach (spleen and stomach are weak and cold). It is recommended that patients with gastric problems consult a doctor in time, strictly follow the doctor’s instructions for medication, and not use medication indiscriminately.
