The identification method is simple, easy and rapid.

According to the shape, color, smell, size, texture, cross section and other characteristics of medicinal materials, using simple physical and chemical reactions such as eye contact, hand contact, nose smell, mouth taste, water test and fire test, we can directly feel the senses, distinguish the authenticity, advantages and disadvantages of medicinal materials, and draw a conclusion in line with objective reality, which is simple, easy and fast.

Character identification is to identify the appearance of medicinal materials by very simple identification methods such as eyes, hands, nose, mouth, water test and fire test.

This is simple, easy and fast. The contents of character identification generally include the following aspects: shape, size, color, surface characteristics, texture, section, smell, taste, water test, fire test and so on.

Research methods of traditional Chinese medicine identification: on the basis of inheriting the heritage of traditional Chinese medicine and traditional identification experience, using the theories, knowledge, methods and technologies of modern natural science.

The history, source, variety morphology, characters, microscopic characteristics, physical and chemical identification, inspection and content determination were systematically sorted out and studied. Establish standardized quality standards, discover and expand the theoretical and practical problems of new drug sources.

Microscopic identification method

The microstructure, cell morphology, inclusion characteristics and optical properties of minerals are observed by microscopy, and the properties of cell walls and cell inclusions or the distribution of effective components of some varieties in tissues are determined by microchemical methods to identify the authenticity, purity and even quality of medicinal materials and whether Chinese patent medicines are administered according to prescriptions.

1. Micro production method

Include transverse or longitudinal sections, surface sections, powder sections, dissociated tissue sections, pollen grains and spores sections, grinding sections, preparations containing powdered medicinal materials and the like.

2. Identification of plant cell walls and inclusions

3. Microscopic measurement

Firstly, the eyepiece micrometer is standardized with a microscope micrometer, and then the size of cells and cell contents is measured under a microscope. Usually, the measurement is carried out under the high-power objective lens, but when the length of longer fibers and non-glandular hairs is to be measured, the measurement is carried out under the low-power objective lens, and the maximum and minimum values are recorded.
