｜The Importance and Necessity of Fundamental Identification｜

　　Some plant characteristics are very similar, including smell, unless a fairly experienced botanist or herbalist can distinguish and identify the plant species. In order to avoid misuse of medicinal materials, it is necessary to strengthen the procurement and planting management of traditional Chinese medicinal materials, the identification of authenticity and variety confirmation, and the correct medicinal materials can truly achieve the purpose of treatment. Therefore, the establishment of the basic index components of Chinese herbal medicine and the identification of the planting base are the most important things.

　　"Original identification of crude drugs" is to use taxonomic methods to know the position in the plant kingdom. To clarify the plant source of medicinal materials, identify the scientific name. For any medicinal material, if the "scientific name" is not clear, it is difficult to guarantee that there will be no errors in the application. For the identification of general medicinal materials, in addition to the above-mentioned "crude drug base identification", the following

Three identification methods to judge:

Character identification: the appearance of the color, smell, size, texture, etc. to determine.

Microscopic identification: Observe the sliced tissue, powder, tissue, cells or inclusions of medicinal materials.

Physical and chemical identification: chemical test, fluorescence phenomenon, chromatography , etc. Carry out fine identification, thin layer chromatography (TLC), high performance liquid chromatography (high performance liquid chromatography, HPLC, fingerprint, etc.) to qualitatively or quantitatively detect the index components and active components.
