Chenggu Ginger

　　"Plant melons and beans around the Qingming Festival." The period around Qingming is also the time to plant ginger.

　　 Ginger is a perennial herbaceous plant of the Zingiberaceae family, cultivated as an annual. It has underdeveloped fibrous roots, and the edible part is its enlarged, irregularly shaped rhizome, which is yellowish-brown or grayish-white in color and has a pungent taste. The above-ground stem grows to a height of 60–70 cm, with lanceolate leaves arranged in two rows; it has a spike-like inflorescence, with green bracts beneath the flowers, orange perianth, and purple labellum dotted with white spots. Ginger thrives in warm, humid environments and requires high levels of nutrients. It is sown around the Qingming Festival and harvested in late autumn. Sliced ginger is known as "dried ginger" and is used for medicinal purposes.

　　 Ginger originated in Indonesia and was later introduced to China. Ginger cultivation in China dates back to the Zhou Dynasty, and the Chinese people have long recognized ginger as a vegetable with high economic value. Hanzhong is a major ginger-producing area, with Chenggu being the foremost. The county has a long history of ginger cultivation and has been famous since ancient times. There are records of ginger planting during the Song Dynasty, and it became nationally renowned during the Ming Dynasty. Surrounding areas such as Yangxian, Xixiang, Nanzheng, and Hantai District also grow ginger.

　　 Located in the central part of the Hanzhong Basin, Chenggu benefits from the influence of the northern subtropical humid monsoon climate, resulting in warm and humid weather without severe summer heat or winter cold. The region enjoys good irrigation conditions, predominantly sandy soil with moderate acidity and alkalinity, moist soil, and deep soil layers. Leveraging these unique natural conditions and traditional ginger cultivation expertise, Chenggu farmers practice meticulous farming, with an annual ginger planting area of around 15,000 mu and an annual yield of 90 million kilograms. The highest yield per mu can reach up to 5,000 kilograms, making Chenggu one of the top ten ginger-producing counties in China. Chenggu ginger is renowned nationwide for its attractive appearance, golden-yellow skin and flesh, tender texture, stout and stringless quality, fine fibers, rich aroma, and high nutritional content. The product is exported to cities such as Beijing, Tianjin, Shanghai, and the northeastern provinces, as well as to Japan and Southeast Asia.

　　 Ginger is highly nutritious, containing carbohydrates, proteins, fats, sugars, ascorbic acid, carotene, and various minerals along with volatile ginger oil. Ginger oil includes more than 10 special components such as zingerone, shogaol, gingerol, zingiberene, phellandrene, and capsaicin. It also contains asparagine, glycine, and various amino acids. These components offer effects such as dispelling cold and wind, antibacterial and anti-inflammatory properties, promoting blood circulation, as well as benefits for beauty, anti-aging, and longevity.

　　 As a culinary seasoning, ginger truly shines with its spiciness. It not only adds a unique flavor and enhances aroma while removing fishy odors, but also helps to invigorate the internal organs and warm the entire body. In daily cooking, whether stewing, braising, stir-frying poultry, meat, or eggs, or making cold dishes with seafood or vegetables, just a sprinkle of minced ginger can enhance the flavor, making the dish more delicious and tasty, while also eliminating any fishy or gamey smells.

　　 Besides being used as a seasoning, ginger can also be processed into salted ginger, sugared ginger, candied ginger, and other products. The pigments extracted from ginger also hold significant economic value. Dried ginger and ginger leaves can also be used to extract aromatic oils. These aromatic oils have a distinctive spicy flavor and are widely used in the processing of beverages and food.

　　 Ginger has medicinal properties and has been used by many renowned Chinese doctors throughout history to treat ailments, accumulating a wealth of experience. Zhang Zhongjing, a medical scientist from the Eastern Han Dynasty, had a particular fondness for using ginger in his treatments. In his two works, "Synopsis of Prescriptions of the Golden Chamber" and "Treatise on Cold Damage Disorders," he highly praised ginger and fully utilized its therapeutic functions. Among the 113 prescriptions for cold damage disorders in the "Treatise on Cold Damage Disorders," 59 use ginger, with the highest dosage in a single prescription reaching up to 50 grams.

　　 Ginger can detoxify. This is recorded in the "Compendium of Materia Medica." As the saying goes, all medicine has some toxicity, and ginger is the nemesis of toxic components found in many traditional Chinese medicines. We often see ginger listed as an "adjuvant" at the end of certain traditional Chinese medicine prescriptions, aimed at neutralizing toxic substances in those medications.

　　 The medicinal efficacy of ginger has drawn attention from many scientists abroad: American scientists have found that ginger is an effective remedy for motion sickness, such as seasickness, carsickness, and airsickness, and it can also treat skin cancer; Japanese scientists discovered that certain components in ginger powder can inhibit the synthesis of prostaglandins; British scientists found that ginger can significantly reduce the cholesterol level in the blood; Danish scientists found that a blood thinner made from ginger can effectively prevent blood clotting; Dutch scientists discovered that ginger has antibacterial properties, particularly against Salmonella in the digestive tract.
