When Lianzhou people talk about ginger, they think of Qingjiang River. Qingjiang is a hilly and semi-arid area, and the climate is suitable for planting ginger. In the year when ginger sells well, a family can harvest 100 tons of ginger a year, which is the main cash crop for Qingjiang people to get rich. Ginger is a typical medicinal and edible plant. It is not only a common food and condiment, but also an indispensable common medicine. The wide application of ginger has a long history in China, which was recorded in the book Records of Famous Doctors 500 years ago. In the Analects of Confucius, there is a saying that "ginger cannot be removed", which means that ginger should be eaten every day all year round. It is said that Confucius has the habit of chewing a few slices of ginger after meals every day. There is a folk saying that "eat radish in winter and ginger in summer, and the doctor doesn't need to prescribe medicine", and there are also sayings that "three slices of ginger in the morning are better than ginseng soup" and "ginger ginseng in October", and there is also a proverb that "three slices of ginger a day don't need the doctor to prescribe medicine". Later generations of Ogilvy Sang's health declaration was that "people can't leave Jiang for a hundred days", which pushed Jiang to an extremely lofty position. Modern medical research has confirmed that ginger contains gingerol, which has the functions of invigorating spleen, stimulating appetite, relieving cough and vomiting. Ginger oil can promote blood circulation, and the whole body feels warm and sweaty after taking it. Therefore, it has a miraculous effect in the early stage of cold and cold.
