Authentic medicinal materials refer to medicinal materials produced under specific natural conditions and ecological environment. Due to centralized production, there is a certain emphasis on cultivation techniques and harvesting and processing, which leads to better quality and better curative effect than similar medicinal materials produced in other regions. Authentic, is authentic, is authentic and reliable.

The geographical environment is very complicated, and the soil, water, climate, sunshine and biological distribution are not exactly the same. Therefore, the quality of the drug itself, that is, the therapeutic effect, is significantly different. For example, the commercial Chinese Pulsatilla has 16 different plant sources, and the genuine Chinese Pulsatilla should be Ranunculaceae. Its roots contain saponins, which can inhibit amoeba, while some foreign bodies of the same name in Dianthus and Compositae have no effect on amoeba. For another example, there are obvious differences in the composition and purgative effect of different varieties of rhubarb. In rhubarb from palm leaves and Tanggu, the content of anthraquinones is mainly in bound state, and the free state only accounts for a small part. These kinds of rhubarb have obvious laxative effect. However, some mixed rhubarb, such as North China rhubarb, Tianshan rhubarb, etc., have a slightly higher anthraquinone content in free state or near bound state, and the diarrhea effect is very poor. In addition, for example, wild ginseng in Changbai Mountain, China, garden ginseng in northeast provinces of China, and ginsenoside content in North Korea and Japan are different, so the saponin monomer content is different, so the pharmacological action and clinical effect are also different. Fritillaria produced in Zhejiang, known as Fritillaria thunbergii, Fritillaria thunbergii or Fritillaria elephant, is good at clearing away lung heat and resolving phlegm, and is suitable for cough with phlegm heat accumulating in lung; Fritillaria cirrhosa, produced in Sichuan, is good at moistening lung and relieving cough, and treating cough caused by heat and fatigue in lung. Up to now, people often praise authentic medicinal materials such as Angelica sinensis in Gansu, Lycium barbarum in Ningxia, Coptidis Rhizoma and Radix Aconiti Lateralis in Sichuan, Glycyrrhiza uralensis in Inner Mongolia, Ginseng in Jilin, Astragalus membranaceus and Codonopsis pilosula in Shanxi, Achyranthes bidentata, Rehmannia glutinosa, Dioscorea opposita and Chrysanthemum in Huaiqing, Henan, Atractylodes lancea in Jiangsu, Poria and Notoginseng in Yunnan, etc. Of course, after all, the number of genuine medicinal materials is limited, so generally speaking, we often use some drugs with the same name but different origins to replace them.
