Place of Production

Place of production is one of the most important factors that influence the herbal properties, actions and curative effects. Due to varied natural conditions such as, different environment, climate, temperature, moisture and sunshine, the same kind of medicinal herbs that grow in different places vary in quality, so, the place of production have been attached great importance.. With long-term use, observation and comparison, the forerunners often assumed that certain medicinal herbs produced in some areas were the best in quality and curative effect. Such medicinal herbs are called ?authentic herbs?. For example. Rhizoma Coptidis, Rhizoma Chuanxiong, and Radix Aconiti Lateralis Preparata produced in Sichuan province, Herba Menthae and Rhizoma Atractylodis in Jiangsu province , Fructus Amomi and Pericarpium Citri Reticulatae in Guangdong province, Radix Ginseng, Herba Asari, and Fructus Schisandrae in the Northeast regions, Radix Notoginseng and Poria in Yunnan province, Raddix Rehmanniae in Henan province, and Colla Corii Asini in Shandong province have long been called famous ?authentic herbs?. But the output of ?authentic herbs? is too far to meet the demand required by the development of Chinese medicine, so while increasing the output of ?authentic herbs?, cultivation techniques and growth factor are studied with approaches of modern science and technology, to provide a specific environment for production. In addition, these herbs are introduced to plant in different regions and medicated animals are raised in other places to ensure their quality and expansion of the source..
