Cinnamomum camphora has a long history in medicine industry, and it is the largest distribution center of medicine villages in China, with a history of 1700 years. Since ancient times, there has been a reputation of "medicine is not unified and medicine is ineffective". Ge jujube hill in the suburbs of the town is a natural medicinal field, stretching for more than 200 miles, with lush vegetation and rich medicinal materials, including animal and plant medicinal materials and mineral medicinal materials 100. As early as the Jian 'an period in the Eastern Han Dynasty, Taoist Zhang Daoling and Ge Xianweng practiced here. On the one hand, they are superstitious about preaching and exorcising evil spirits, on the other hand, they collect medicines and alchemy to treat diseases and teach them how to make them. Later, Ge Hong, the grandson of the Ge family, summed up his medical experience and wrote "Emergency", which was spread all over the world. During the Tang and Song Dynasties, camphor tree pharmaceutical industry developed day by day, and the number of drug collectors and drug sellers increased day by day. Drug stores, drug stores and branch stores are gradually emerging and expanding to other provinces. In the early Ming Dynasty, there were three palaces (namely Wang Yao Temple) built here. Every year, on April 28th, the birthday of Sun Simiao, a famous doctor in the Tang Dynasty, a trading place is set up near the temple, where drug dealers from all walks of life gather to trade. In the late Ming and early Qing dynasties, there were more than 200 Chinese medicine shops in Zhangshu. At the same time, drug dealers from other provinces also came here to open pharmacies and even set up associations. It has gradually become a distribution center for medicinal materials. Up to now, there are still many well-preserved blast wells, medicine washing pools, ancient temples and medicine halls in China. Zhangshu people have collected and processed Chinese herbal medicines for generations, and mastered many secret recipes, which are unique in frying, soaking, soaking, baking, drying, cutting and storing. The tablets cut by excellent chemists are "as thin as paper, can be blown up, have uniform cross section and beautiful shape", and have good color, fragrance, shape, taste and effect. Pharmacists, pharmacists and drug dealers of Cinnamomum camphora traveled all over the country, collecting and purchasing high-quality raw materials and transporting them back for processing, making Cinnamomum camphora's medicinal materials complete in variety and excellent in texture. Therefore, Cinnamomum camphora has become the production, processing, processing and management center of Chinese herbal medicines in China.
The formation of "drug capital" is closely related to its rich medicinal resources and expertise in planting, processing, transportation and storage, in addition to superior geographical conditions and developed waterway transportation. There are more than 200 kinds of natural medicinal materials in jujube hill, and the world-famous Fructus Aurantii and Fructus Aurantii Immaturus are one of the local specialties. Cinnamomum camphora is local and has strict requirements on the quality of medicinal materials. Medicinal materials must be pure, and the processing of decoction pieces should be fine. Today, "Wang Yao Temple Fair" has developed into an annual national medicinal materials exchange meeting. Once an invitation is issued every year, pharmaceutical colleagues from Hong Kong, Singapore and all provinces, autonomous regions and municipalities in China flock to us. At that time, camphor tree will become the world and ocean of medicine. On the wide terrace outside the East Gate of Duyao, a magnificent building complex dedicated to trading activities has sprung up, with a total area of over 15000 square meters, which can accommodate more than 10000 people for trading activities at the same time.
