Character identification is a very simple identification method to identify the appearance of medicinal materials by eye observation, hand touch, nose smell, mouth taste, water test and fire test. These methods have accumulated rich traditional identification experience in the treasure house of traditional Chinese medicine, and are simple, easy and fast. Character recognition is the same as source recognition. In addition to carefully observing samples, it is sometimes necessary to check samples and documents.

For some regional strong or newly added varieties, there is often a lack of relevant information and standard samples for identification. You can send a few samples to the Chinese herbal medicine departments or drug inspection offices in the provinces and autonomous regions where medicinal materials are produced to understand the situation or ask people to assist in identification. If necessary, you can go to the place of origin to investigate, collect physical specimens, and understand the production, processing, sales and use for identification and research. Intuitive personality identification is very important, and it is also one of the basic skills necessary for Chinese medicine appraisers.
