Problems solved by technology

Repeated drying processes such as sun exposure and night boredom and water infiltration softening process, as an aromatic traditional Chinese medicine, its active ingredients are easily lost with water, and active ingredients such as volatile oil will also be lost. The sweating process of sun exposure and night boredom can also make patchouli The internal composition of the medicinal material changes, which will eventually affect the quality of the patchouli medicinal material; and the storage and transportation of the original medicinal material are inconvenient

Abstract

The invention belongs to the field of traditional Chinese medicine, and particularly relates to a preparation method of herba pogostemonis decoction pieces. The preparation method comprises the following steps: taking a clean fresh herba pogostemonis medicinal material; air-drying the clean fresh herba pogostemonis medicinal material under the sunlight or in ventilation drying equipment with a temperature of 30 DEG C to 40 DEG C, continuously drying the clean fresh herba pogostemonis medicinal material for 5 to 7 hours; then under the coverage of a breathable cover, stacking and sweating for 16 to 17 hours; removing moisture on the surface of the herba pogostemonis medicinal material after sweating, cutting and drying to obtain herba pogostemonis decoction pieces. The preparation method isa new method obtained by carrying out optimization according to an existing production place processing and preparation method. The herba pogostemonis decoction pieces prepared by the method are similar in quality and medicine effect analysis with herba pogostemonis decoction piecess prepared by a method in the chinese pharmacopoeia, and accords with requirements of the chinese pharmacopoeia. Water decoction of the herba pogostemonis decoction pieces prepared by the method disclosed by the invention also has the anti-inflammatory activity.

Description

technical field [0001] The invention belongs to the technical field of Chinese herbal medicine, and particularly relates to a preparation method and application of patchouli decoction pieces.
