The physicians of the past dynasties have attached great importance to authentic medicinal materials, and believed that “all kinds of herbs and insects have their own suitable properties. The smell and power are extraordinary.” Generally, traditional Chinese medicinal materials pay attention to authentic medicinal materials, which refer to medicinal materials produced in regions with specific natural conditions and ecological environment. Because of the concentrated production, cultivation techniques, harvesting, and processing also have certain attention to detail. Produced in other areas of good quality, good curative effect. For example, Coptis chinensis and Aconite from Sichuan, Goji berries from Gansu, Codonopsis from Shanxi, dried tangerine peel from Guangdong, ginseng and Schisandra from Northeast China, Poria from Hubei and Yunnan, Ejiao from Shandong, and the “Four Huai Yaos” from Henan, namely Huaidihuang, Huaijiao, etc. Yam, Achyranthes, and Chrysanthemum are all “authentic medicinal materials”.
