Abstract
The invention discloses a preparation method for a compound houttuynia cordata preparation. The preparation method comprises the following steps: (1) extracting volatile oil from houttuynia cordata and fructus forsythiae; (2) extracting medicine drugs of the houttuynia cordata and fructus forsythiae which are extracted to obtain the volatile oil, isatis tinctoria and lonicera japonica by water; filtering an extracting solution and concentrating the filtering solution until the relative density is 1.10-1.30 (at 60 DEG C); adding ethanol until the alcohol content is up to 60%-85%; standing and filtering; recycling the ethanol and concentrating to form a fluid extract; (3) extracting scutellaria baicalensis by using water and filtering an extracting solution; adjusting the pH (Potential of Hydrogen) value of the filtering solution to be 1.0-3.0; keeping the heat at 60-95 DEG C for 0.5-2.5 hours; standing and filtering; washing sediments by sequentially using 30%-95% of the ethanol and the water until the pH value is 4-6 to obtain a scutellaria baicalensis extract; and (4) combining the volatile oil, the fluid extract and the scutellaria baicalensis extract and mixing uniformly by adopting a mechanical grinding method; and then preparing a mixture into pills to obtain the product.
Description
technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to a preparation method of a traditional Chinese medicine preparation for clearing away heat and detoxifying.
