Medicinal herbs rhizomes are ovoid, cylindrical or fusiform, some forked branches, 2-5cm long, 1-3cm in diameter, with a dark yellow surface, wrinkled texture and obvious links with leaf scars, and rounded branching scars and fibrous root scars. Solid texture, section brownish-yellow to golden-yellow, horny, waxy luster, endothelial branch ring is obvious

The yellow ginger is also known as wear the ground dragon, the earth name of the dumb side of the ginger, the scientific name of peltate leaf yam Dioscorea, perennial herbaceous vine, its tuber has high medicinal and chemical value, after processing can be extracted saponin, bisectin and other medicines, chemicals, hormone drugs is an essential component of the metaphor of the "mother of hormones". "Mother of hormones", and widely used in cosmetics, health care, contraception, analgesia, anesthesia and other drugs, is a more stable market demand for medicinal herbs. And China's production of saponin and accounted for 50% of the world. In the past two decades, with the promotion of population planning policies and the widespread use of hormone drugs, international and domestic market demand for ginger (saponin) is increasing day by day, ginger purchase price has been rising, saponin prices have also risen again and again. And saponin production enterprises mostly due to a lack of raw materials and start insufficient. Ginger production is facing a

Ginger, also known as shield leaf Dioscorea (Rhizoma Dioscoreae Zingiberensis, (English) Peltate Yam Rahizome), fire root, the Department of monocotyledonous plants Dioscoreaceae Dioscorea genus, for the Dioscorea Dioscorea zingiberensis C.H. Wright rhizome, is a perennial plant of Dioscorea zingiberensis C.H. Wright rhizome, is a perennial plant of Dioscorea zingiberensis C.H. Wright rhizome. Wright's rhizome, is a perennial twining herb, with underground tubers, rich in starch, twining stems can be up to more than 2 meters long , leaves opposite, triangular-cordate, entire, with palmate veins. Flowers unisexual, dioecious, spikes pendulous; capsule trigonous-globose, with seed wings; underground rhizome is a famous starch plant, but also nourishing food, but also medicinal plants; fruiting Dioscorea female plants, pendulous infructescence, fruit reflexed. Herbaceous twining vine, stems levitated, sometimes with short spines at the base of branches or petioles, simple leaves alternate, peltate, foliage often with irregular masses of yellowish-white mottling, margins shallowly undulate, base cordate or truncate; flowers dioecious or monoecious; male inflorescences spikelike, male flowers in clusters of 2-3, perianth purplish-red, stamens 6; female inflorescences racemose spikelike. Seeds chestnut-brown, surrounded by thin membranous wings. Seeds chestnut-brown, surrounded by thin membranous wings. Rootstock cylindrical, often with irregular branches, branches of different lengths, 1.5-3cm in diameter, surface brown, rough, with obvious longitudinal wrinkles and white dotted root scars, hard, powdery, orange-yellow cross-section, bitter taste. Born in the valleys on both sides of the stream, forest edge or scrub; mainly distributed in E, Sichuan, Shaanxi, Liao, Ji, black, and other eight provinces, cities and districts above 300 meters above sea level in the mountainous hills and alpine mountainous areas, for many years people on the wild resources of ginger unplanned plundering and mining, resulting in the depletion of the species day by day. As a result, China's steroidal plants will soon face the situation of insufficient supply of raw materials, which will seriously threaten the development of China's steroidal drug industry. Adoption of asexual reproduction technology, after years of experiment, through artificial cultivation planting, and achieved successful experience. Therefore, the large-scale use of artificial cultivation of ginger is imperative imperative.

The rhizome of ginger fruit can be directly into the medicine, there is the effect of dampness, clearing heat and detoxification; now found that ginger can be extracted from 120 kinds of ingredients and industry can not be synthesized in large quantities of expensive steroid hormones - saponins; in addition to the rhizome contains 50% starch, which can be synthesized for the production of citric acid, brewing and alcohol, alcohol water and waste acid solution can be extracted agricultural nucleic acid, and the production of alcohol and waste acid. Acid solution can be extracted agricultural nucleic acid. Saponin polyester processing products "bisene", "cystine", "anhydrous cystine" and a variety of extended products and China's export of foreign exchange is an important product of the international market is very tight sales. Foreign businessmen heard, scrambling to order so the economic price of ginger is very high, the development prospects are very considerable.

Ginger rhizome containing diosgenin (dioscin), as the raw material of hormone drugs. Saponin element, accounting for the world content of more than 1% of about 30 kinds, China has 50 kinds, of which 17 kinds, 1 subspecies, 2 varieties containing saponin element, accounting for more than 50% of the world containing saponin element plants, the content of up to 16.15%, more than the Mexican Dioscorea spicata 15% of the record is the world's ace species. Ginger is ideal for the extraction of important raw materials for steroid hormone drugs, saponin element (commonly known as saponin), its steroidal structure compounds to be modified, you can get a variety of different steroid hormone drugs. From the rhizome of ginger extracted from the initial products for the soap androstenedione, progesterone acetate (monolipid), prednisone, cortisone series and oxytocin, contraceptives and other intermediates or thousands of drugs, in short, ginger as raw material, can be synthesized into a series of products such as sex hormones, anabolic hormones and corticosteroids, etc., the country and people's livelihood, and therefore the pharmaceutical industry called it "medicinal gold! "In addition to domestic needs, it has been sold to more than 120 countries and regions such as the United States, Germany, France and Japan.

In addition, ginger in addition to saponins, also contains 45 ~ 50% of the starch, can be used in the brewing industry to produce alcohol, yeast powder, inosine powder, glucose, etc.; Containing 40 ~ 50% of the cellulose, carboxymethyl cellulose can be produced. Extraction of saponin waste liquid, can be extracted agricultural nucleic acid, is a high-quality fertilizer. Rhizomes also have a wide range of uses in medicine, food, high-level cosmetics, veterinary medicine and other industries, such as rhizomes directly into the medicine, with expectorant, clearing heat and detoxification effect, folk used in the treatment of acute septic infection of the skin, soft tissue injuries, bee stings, insect bites and a variety of surgical inflammation, as well as the role of the strengthening of the body and bones. The water-soluble active substance can produce Shieldleaf Coronary Heart Ning, which is used for the treatment of coronary heart disease with good effect and little side effect. Chengdu Institute of Biology developed the Diao heart blood Kang, with the regulation of metabolic functions, the treatment of atherosclerosis and the cardiovascular system of diseases have a better effect, selling well in domestic and international markets. In addition, Wuhan Institute of Botany, Chinese Academy of Sciences, research found that ginger active substance is to kill snails, anti-schistosomiasis ideal drugs, not only snail effect is good, but also does not pollute the environment, to maintain the ecological balance
