Abstract

A process for preparing the coarse dust of root and rhizome type Chinese-medicinal materials includes preparing coarse dust and loading it in bags of different dosages for using them as the raw materials of Chinese-medicinal decoction. Its advantages are high extracting rate and low cost.

Description

Technical field [0001] The invention relates to a method for preparing coarse powder of Chinese medicinal materials of roots and rhizomes. That is to say, after the roots and rhizomes are processed into coarse powder, they are packed into bags of different specifications and used as raw materials for preparing traditional Chinese medicine decoctions. Background technique [0002] Decoction, also known as decoction, is one of the main dosage forms in the clinical application of traditional Chinese medicine, with a history of more than 3,000 years. Because of its rich content and comprehensive ingredients; flexible formula, which can be added or subtracted according to the syndrome; suitable for the needs of TCM dialectical treatment; easy to absorb and quick to take effect, it is still widely used today. The required medicinal materials have undergone generational evolution, and now they are basically processed and cut into slices or made into blocks, strips, silks and other...

AI Technical Summary

Problems solved by technology

According to the 2000 edition of the Pharmacopoeia of the People's Republic of China (Part 1), the thickness of the decoction pieces is: thin slices 1-2mm, thick slices 2-4mm, obviously its volume is relatively large (ie, the block is large), and the leaching effect is relatively small due to the relatively small surface area. Difference

[0003] However, if the powder is too fine, the leaching effect is not ideal, because it sinks to the bottom and is easy to stick to the pan and gelatinize, which affects the dissolution and release of active ingredients.
