Ginger is pungent and warm, good at dispelling cold, resolving phlegm and relieving cough, and can stop vomiting and detoxify. Clinically, it is often used to treat exogenous wind-cold and stomach-cold vomiting, and it is called "the holy medicine for vomiting at home" by predecessors. Ginger frying is to make use of these characteristics of ginger and use ginger juice as an auxiliary material to process drugs, so as to enhance expectorant and antitussive effects, reduce adverse reactions and vomiting, and reduce its toxic and side effects. If bamboo shavings are good at clearing away heat and resolving phlegm, ginger roasting can enhance the effect of reducing adverse reactions and stopping vomiting; Magnolia officinalis is spicy and irritating to the throat. Its side effects on throat irritation can be eliminated by baking ginger, and the effect of soothing the stomach can be enhanced. Rhizoma Coptidis and Rhizoma Zingiberis Recens can relieve their bitterness and coldness and treat vomiting caused by stomach heat.

Although dried ginger is the same as ginger, its properties are different because of the different qualities of fresh dried ginger. Dried ginger is hot, pungent, strong, good at warming the middle and returning to yang, and can warm the lungs and dissolve the drink. Clinically, it is often used to treat symptoms such as deficiency and cold of middle energizer, impotence and dyspnea caused by cold drinks. Therefore, the performance of ginger juice prepared with dried ginger is different from that of raw ginger juice. If ginger juice made from dried ginger is used to process drugs, it will affect the processing effect of drugs. If the purpose of drug processing cannot be achieved, the efficacy of drugs with antiemetic effect will not be enhanced.

According to the theory of traditional Chinese medicine, ginger is a product that helps yang. Since ancient times, Chinese medicine has always said that "people can't live without ginger for a hundred days." Su Shi, a poet in the Song Dynasty, described an 80-year-old monk in Jingci Temple, Qiantang, Hangzhou, with a childish face. "He persuaded Jiang for forty years, so he is not old." Legend has it that White Snake stole Xiancao to save Xu Xian. This fairy grass is ginger bud. Ginger is also called "rejuvenation grass" and ginger soup is also called "rejuvenation soup".
