Problems solved by technology

[0004] The shortcomings in the preparation method of existing compound Houttuynia cordata preparations, 1. Failure to utilize the aromatic ingredients contained in Houttuynia cordata, forsythia and honeysuckle with pungent coolness and pathogenicity, and the functions of dispelling wind and heat
2. The alcohol content in the alcohol precipitation process is too high, resulting in too much loss of ingredients with heat-clearing and detoxifying functions in the prescription
The disadvantage of this method is that the production equipment used is unconventional equipment, which is expensive, the production cost is high, and the product price will be greatly increased, which will increase the burden on patients.

Embodiment 1-3

[0021] 1. extract

[0022] According to the ratio in Table 1, add Houttuynia cordata, forsythia, and honeysuckle with 10 times the amount (weight, the same below) of water, steam distillation to extract 160ml of aromatic water and store it in another container, add 8 times the amount of water to the dregs and decoct for 1 hour, Filter and set aside. Scutellaria baicalensis and Banlangen are decocted twice with water, first add 10 times the amount of water and decoct for 1.5 hours; for the second time add 8 times the amount of water and decoct for 1 hour.

[0023] 2. filter, concentrate

[0024] Combine the decoction liquid, settle naturally for more than 8 hours, take the supernatant, filter the lower sediment with a 100-mesh sieve, and combine the filtrate and supernatant. Take the filtrate and carry out vacuum concentration at 70-80°C until the relative density is 1.18-1.20.

[0025] 3. Alcohol precipitation

[0026] Take the concentrated solution, slowly add 85% etha...

Embodiment 4

[0038] Concrete scheme is with embodiment 1, and difference is first three steps, specifically as follows:

[0039] 1. extract

[0040] According to the ratio in Table 1, add 12 times the amount of water to Houttuynia cordata, forsythia, and honeysuckle, steam distillation to extract 200ml of aromatic water and store in another container, add 10 times the amount of water to decoct the medicinal residues for 1 hour, filter, and set aside. Scutellaria baicalensis and Banlangen are decocted twice with water, the first time with 12 times the amount of water and decocted for 1.5 hours; the second time with 10 times the amount of water and decocted for 1 hour.

[0041] 2. filter, concentrate

[0042] Combine the decoction liquid, settle naturally for more than 8 hours, take the supernatant, filter the lower sediment with a 100-mesh sieve, and combine the filtrate and supernatant. The filtrate was concentrated in vacuum at 70°C until the relative density was 1.18.

Embodiment 5

[0047] Concrete scheme is with embodiment 1, and difference is first three steps, specifically as follows:

[0048] 1. extract

[0049] According to the ratio in Table 1, add 12 times the amount of water to Houttuynia cordata, forsythia, and honeysuckle, steam distillation to extract 200ml of aromatic water and store in another container, add 10 times the amount of water to decoct the medicinal residues for 1 hour, filter, and set aside. Scutellaria baicalensis and Banlangen are decocted twice with 11 times the amount of water for 1.5 hours; for the second time, 9 times the amount of water is added for 1 hour.

[0050] 2. filter, concentrate

[0051] Combine the decoction liquid, settle naturally for more than 8 hours, take the supernatant, filter the lower sediment with a 100-mesh sieve, and combine the filtrate and supernatant. The filtrate was concentrated in vacuo at 80°C until the relative density was 1.20.

Abstract

The invention belongs to the technical field of traditional Chinese medicine, and relates to a preparation method of compound Houttuynia cordata preparation, in particular to a preparation method of compound Houttuynia cordata mixture for the treatment of sore throat and tonsillitis caused by exogenous wind heat and a preparation method of the mixture. In the preparation method of the compound Houttuynia cordata mixture, the Houttuynia cordata, Scutellaria baicalensis, isatis root, fructus forsythiae and honeysuckle which are used as bulk drug and prepared with auxiliary materials, the method comprises the following steps: extracting, filtering, concentrating and preparing the mixture, wherein the extraction step refers to distill the Houttuynia cordata, fructus forsythiae and honeysuckle with steam in advance and extract aromatic water, then, water is added to decoct drug residues, filtering is performed, and the obtained decoction liquid is mixed with the decoction liquid of the Scutellaria baicalensis and the isatis root, and the mixed liquid is filtered and concentrated. The preparation method of compound Houttuynia cordata mixture can fully use volatile components, which have functions of cooling, eliminating pathogens and removing wind heat, of the Houttuynia cordata, the fructus forsythiae and the honeysuckle, so that alcoholicity of alcohol precipitation process is lowered, and loss of components having functions of clearing heat and detoxicating in the formula is reduced.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine, and relates to a preparation method of Houttuynia cordata preparation, in particular to a preparation method of compound Houttuynia cordata mixture used for sore throat and tonsillitis caused by exogenous wind-heat. The preparation method of this mixture. Background technique [0002] Upper respiratory tract infection is common disease, frequently-occurring disease. In recent years, due to the frequent flow of people and the poor orientation of various flow links, the incidence rate has an upward trend. Upper respiratory tract infection can occur in all seasons, especially in spring and winter. With the seasonal spread, the incidence is concentrated in densely populated places, and because upper respiratory infection is contagious, the incidence is very high in susceptible seasons. High, the onset is relatively fierce, it is a great threat to children, the elderly and peopl...
