The necessity of polarizing mirror inspection:

1.Application in mineral based traditional Chinese medicine

The vast majority of mineral based traditional Chinese medicines are crystalline minerals, such as quartz, mica stone, and cold water stone. Strong and multi colored interference bands will appear in the dark field, which are very intuitive and obvious.

2.Application in animal based traditional Chinese medicine

The grinding plates of animal bones and teeth may not be visible under a regular microscope, but under a polarizing microscope, they exhibit strong color and stripe contrasts. Polarization can also distinguish normal cells from tumor cells, as normal cells often exhibit left-handed polarization, while tumor cells tend to exhibit right-handed polarization; Some animals' striated muscles and hair can also be examined using a polarizing microscope. Many animal medicinal herbs such as leopard bone, ivory, sea dragon, seahorse, turtle shell, whole armor, snakes, and even many animal horn, stone, secretion medicinal herbs such as deer antlers, antelope antlers, bezoar, horse treasure, monkey jujube, pearl, musk, bird's nest, etc. can be examined using a polarizing microscope.

3Application in plant-based medicinal materials

Many plant medicinal materials exhibit stable and specific polarization phenomena in their tissues, cells, and contents. Using polarizing glasses for observation can quickly and accurately identify identification features and eliminate interference

3.1Starch granules

All plant starch granules exhibit polarization phenomenon. Under a polarizing microscope, in a dark background, starch granules appear as bright spherical shapes with two intersecting transient stripes, and the intersection point is the navel of the starch granules.

Microscopic identification of complete medicinal materialsSuitable for observing the complete tissue structure of medicinal materials. Firstly, select the appropriate parts of the medicinal herbs and make microscopic specimens before observing them under a microscope. When making films, most medicinal herbs can be sliced horizontally, and some even need to be sliced vertically. The slicing methods include manual slicing, sliding slicing, paraffin slicing, etc. Among them, the manual slicing method is the most simple, fast, and commonly used. Hand cut slices must be processed and sealed with appropriate solutions in order to clearly observe tissue structure and the shape of cells and their contents. Sometimes, in order to observe certain cellular tissues such as fibers, ducts, etc., it is also necessary to prepare tissue dissociation slices and powder slices. When observing the residual content in the tissue slices or powders of medicinal materials, glycerol acetic acid test solution or distilled water is generally used to observe the starch granules. Polarized microscopy can also be used to observe the polarization phenomenon of unglazed starch granules; Observe paste powder particles, starch particles, oil droplets, resin, etc. using dilute glycerol tablets; Using hydrated chloral solution, inulin can be immediately observed without heating. If heated, it can dissolve starch granules, proteins, chloroplasts, resins, volatile oils, etc., and cause contracted cells to expand, resulting in clear cell tissue and significant characteristics of calcium oxalate crystals.

Microscopic identification of broken medicinal materialsFor large pieces of medicinal herbs, tissue slices can also be cut, and the method is generally the same as the microscopic identification method for intact medicinal herbs; When the block is small and difficult to slice, chemical reagents can be used to dissect the plant tissue and make dissociated tissue slices for observation, or scrape them off

Microscopic identification of powdered medicinal materials and observation of powder slices. For chopped grass and leaf medicinal herbs, surface observation is still the most commonly used method.Processing and sealing methods of powder materials and microscopic identification of intact medicinal materials

be similar. The powder flakes made can undergo microscopic chemical reactions. Identification of authenticity and purity based on the characteristics of tissue fragments and post contents observed under a microscope. The microscopic identification method of traditional Chinese patent medicines and simple preparations, such as pills, powders and chongs, is basically the same as that of powder medicinal materials. Measuring the size of cells and their contents is also an important basis for microscopic identification. In particular, the size of the same kind of cells or after contents in traditional Chinese patent medicines and simple preparations can often be used as a distinguishing feature between varieties.Microscopic identification of mineral drugs
