Pursuant to 35 U.S.C. § 119 and the Paris Convention, this application claims the benefit of Chinese Patent Application No. 202311530281.7 filed Nov. 16, 2023, the contents of which are incorporated herein by reference.
The present application relates to the technical field of traditional Chinese medicine, more particularly to a traditional Chinese medicine composition for treating pediatric exogenous wind-heat and a preparation method therefor.
Commonly known as a common cold, a cold disorder is an infectious inflammation of the upper respiratory tract caused by viruses or bacteria. It is highly contagious and can occur in all seasons, but is more common in winter and spring. Traditional Chinese medicine believes that when the climate changes suddenly, the cold and heat are abnormal, or the wind blows when going out, the internal and external functions of the human body are weakened, and the wind-cold and wind-heat take advantage of the deficiency to invade, invading the lung and defense qi, and the defense surface is not solid and causes disease. The main symptoms are fever, nasal congestion, runny nose, sore throat, and headache, and sometimes joint pain and general discomfort. Pediatric wind-heat cold is a common disease. Because children have special physiological and disease characteristics, the various pains and diseases caused by children's illnesses cause adverse harm to children's bodies. Although most children's diseases are not difficult to diagnose clinically, the implementation for the treatment is more difficult. There are many pharmaceutical preparations on the market to treat children's colds, including Western medicine and Chinese medicine. Western medicine has serious side effects, and Chinese medicine has a worse smell. Children are weak, so when using medication, attention should be paid to both the efficacy and the child's tolerance.
Therefore, how to develop a traditional Chinese medicine composition with significant efficacy on children has become a realistic issue.
It is an objective of the present application to provide a traditional Chinese medicine composition for treating pediatric exogenous wind-heat, which has significant efficacy for pediatric patients.
It is another objective of the present application to provide two preparation methods for the traditional Chinese medicine composition for treating pediatric exogenous wind-heat, to produce this highly effective composition.
To address the above technical problems, the following technical solutions are adopted.
In a first aspect, embodiments of the present application provides a traditional Chinese medicine composition for treating pediatric exogenous wind-heat, which comprises the following raw materials: a Menthae Haplocalycis Herba, a Bombyx Batryticatus, a Gypsum Fibrosum, an Anemarrhenae Rhizoma, a Scutellariae Radix, an Artemisia Annuae Herba, a Scrophulariae Radix, and a Lycii Cortex.
In a second aspect, embodiments of the present application provides a preparation method for the traditional Chinese medicine composition for treating the pediatric exogenous wind-heat. The preparation method comprises the following steps:
In a third aspect, a preparation method for the traditional Chinese medicine composition for treating the pediatric exogenous wind-heat comprises the following steps: collecting and mixing the raw materials to obtain a second mixture;
submerging the second mixture in water, heating until reaching a boiling state, and decocting the second mixture at the boiling state, then filtering to obtain a decoction liquid and a decoction residue; mixing the decoction residue with water, heating and refluxing to obtain a reflux liquid, and mixing the decoction liquid with the reflux liquid, concentrating a resulting mixed liquid to obtain a concentrated liquid; and
spray drying the concentrated liquid and mixing the same with an excipient to form granules, and screening the granules to obtain the traditional Chinese medicine composition for treating the pediatric exogenous wind-heat.
Compared with existing technology, advantages or beneficial effects of the traditional Chinese medicine composition for treating pediatric exogenous wind-heat and the preparation method therefor according to embodiments of the present application are summarized as follows:
The researchers of the present application believe that pediatric upper respiratory infections fall under the category of “colds” or “wind-cold” in traditional Chinese medicine (TCM). Since the lung governs the skin and the pores, and children's organs are delicate with weak lung defense functions, when they are exposed to the wind-heat, or the wind-cold enters the interior and transforms into heat, then the defensive surface is out of harmony and the lung qi fail to disperse properly. This leads to symptoms of defensive surface and the upper jiao of pulmonary system, such as fever, nasal congestion, runny nose, cough, and headache.
Based on the above reasons, the present application uses the Menthae Haplocalycis Herba, the Bombyx Batryticatus, and the Artemisiae Annuae Herba which are clear and refreshing flavored, gently cooling and dispersing, and are effective in releasing Wei-defence phase pattern; as well as the Gypsum Fibrosum, the Anemarrhenae Rhizoma, and the Scutellariae Radix, which are bitter and cold flavored, and cold and cool-natured, and are effective in clearing heat from the qi level; added with Scrophulariae Radix and the Lycii Cortex, which help nourishing yin and generating fluids, draining fire and detoxifying, preventing heat from damaging yin, and have the purpose of “for every measure of body fluids preserved, there is a measure of vitality maintained”. In this way, external wind is dispersed, heat and toxins are cleared, yin fluids are preserved, and fever is rapidly reduced to aid in the pediatric patient's recovery. The combination of these components have the effect of dispersing wind and dissipating heat, clearing heat and detoxifying, generating fluids and protecting yin, function in treating the pattern involving both Wei-defence and qi phases, and treating both the surface and interior conditions, and are primarily used to removing wind and clearing heat, and detoxifying and protecting yin, so as to treating pediatric exogenous wind-heat and the pattern involving both Wei-defence and qi phases, with symptoms such as persistent high fever, sweating or scant sweating, nasal congestion, runny nose, red and swollen throat, yellow urine, dry stool, red tongue with thin white or thin yellow coating, and slippery rapid pulse, and pediatric upper respiratory tract infections with the above syndromes.
In conclusion, the traditional Chinese medicine composition provided in the present application can effectively treat pediatric wind-heat exterior conditions, significantly improve clinical symptoms and signs in pediatric patient, enhance immune function, and has a notable therapeutic effect with high safety, making it suitable for clinical promotion.
The present application also provides two preparation methods for the traditional Chinese medicine composition, which maximize the extraction of beneficial substances from the ingredients and efficiently and conveniently produce the traditional Chinese medicine composition, which facilitates the bulk production.

A screened solid extract paste was mixed with an excipient (dextrin) at a mass ratio of 1:3 to obtain a traditional Chinese medicine composition in a powder form.
The traditional Chinese medicine composition in the powder form was fluidized under the driving of the heated air. Water was added at a mass ratio of 1:3 to the traditional Chinese medicine composition in the powder form, and a peristaltic pump was adopted to transport the water to a spray gun pipe, where the water was atomized into small droplets by 2 bar compressed air and dispersed in the fluidized bed at a speed of 21.6 g/min/kg and collided with the traditional Chinese medicine composition in the powder form to form granules. Air was continued being introduced for 30 mins, the formed granules were screened by a 14-mesh sieve to obtain a traditional Chinese medicine composition for treating pediatric exogenous wind-heat with a water content less than 9 wt. %.
This example was basically similar to Example 3, except that the preparation method was different.
A traditional Chinese medicine composition for treating pediatric exogenous wind-heat was prepared by the following preparation steps:
5 g of a Menthae Haplocalycis Herba, 5 g of a Bombyx Batryticatus, 18 g of a Gypsum Fibrosum, 10 g of an Anemarrhenae Rhizoma, 10 g of a Scutellariae Radix, 10 g of an Artemisia Annuae Herba, 10 g of an Scrophulariae Radix, and 10 g of a Lycii Cortex were provided as raw materials.
The above raw materials were collected and mixed to obtain a second mixture.
The second mixture was submerged in water according to a mass ratio of the second mixture to water being 1:10, heated to reach a boiling state, and decocted at the boiling state for 30 mins. Then filtration was performed to obtain a decoction liquid and a decoction residue. The decoction residue was mixed with water according to a mass ratio of the decoction residue to water being 1:6, then heated to a reflux state, which state was maintained for 30 mins, so as to obtain a reflux liquid. The decoction liquid was mixed with the reflux liquid, and a resulting mixed liquid was concentrated for 2 hrs to obtain a concentrated liquid having a relative density of 1.2.
The concentrated liquid was spray dried at a temperature of the inlet air being less than 70° C. and a feed flow rate being 1 kg/min, then mixed with an excipient at a mass ratio of 1:3, a resulting product was screened by a 14-mesh sieve to obtain the traditional Chinese medicine composition for treating the pediatric exogenous wind-heat.

Then filtration was performed to obtain a decoction liquid and a decoction residue. The decoction residue was mixed with water according to a mass ratio of the decoction residue to water being 1:8, then heated to a reflux state, which state was maintained for 60 mins, so as to obtain a reflux liquid. The decoction liquid was mixed with the reflux liquid, and a resulting mixed liquid was concentrated for 2.5 hrs to obtain a concentrated liquid having a relative density of 1.25.
The concentrated liquid was spray dried at a temperature of the inlet air being less than 70° C. and a feed flow rate being 1.3 kg/min, then mixed with an excipient at a mass ratio of 1:3, a resulting product was screened by a 14-mesh sieve to obtain the traditional Chinese medicine composition for treating the pediatric exogenous wind-heat.
This example was basically similar to Example 5, except that the preparation method was different.
A traditional Chinese medicine composition for treating pediatric exogenous wind-heat was prepared by the following preparation steps:
9 g of a Menthae Haplocalycis Herba, 9 g of a Bombyx Batryticatus, 24 g of a Gypsum Fibrosum, 14 g of an Anemarrhenae Rhizoma, 14 g of a Scutellariae Radix, 14 g of an Artemisiae Annuae Herba, 14 g of an Scrophulariae Radix, and 14 g of a Lycii Cortex were provided as raw materials.
The above raw materials were collected and mixed to obtain a second mixture.
The second mixture was submerged in water according to a mass ratio of the second mixture to water being 1:15, heated to reach a boiling state, and decocted at the boiling state for 90 mins. Then filtration was performed to obtain a decoction liquid and a decoction residue. The decoction residue was mixed with water according to a mass ratio of the decoction residue to water being 1:10, then heated to a reflux state, which state was maintained for 90 mins, so as to obtain a reflux liquid. The decoction liquid was mixed with the reflux liquid, and a resulting mixed liquid was concentrated for 3 hrs to obtain a concentrated liquid having a relative density of 1.3.

This example was basically similar to Example 4 except that Scrophulariae Radix was replaced by Phragmitis Rhizoma.
This example was basically similar to Example 4 except that Menthae Haplocalycis Herba was replaced by Arctii Fructus.
As shown in Table 1, compared with the control groups 1-3, the treatment group had obvious effects on reducing fever, cough, sore throat, and nasal congestion and runny nose, and had obvious therapeutic effects on cough, sore throat, and nasal congestion and runny nose.
It was known from Table 2 that the treatment group only had 2 cases that were ineffective to the treatment, and the control group 1 had 12 cases that were ineffective to the treatment; and the cured, significantly effective, effective, and total effective rate of the treatment group were better than those of the control groups. When comparing the treatment group and the control groups 2-3, Scrophulariae Radix and Phragmitis Rhizoma both had the effect of clearing heat and draining fire, Arctii Fructus and Menthae Haplocalycis Herba both had the effect of dispersing wind and dissipating heat, and the therapeutic effect of the traditional Chinese medicine composition obtained by replacing the medicinal materials with similar efficacy was not as good as before the replacement. It can be seen that replacing the raw materials in the formula of the present application with medicinal materials with similar efficacy will affect the efficacy, and the compatibility scheme of the present application is feasible and has outstanding effects.
In conclusion, the researchers of the present application believe that pediatric upper respiratory infections fall under the category of “colds” or “wind-cold” in traditional Chinese medicine (TCM). Since the lung governs the skin and the pores, and children's organs are delicate with weak lung defense functions, when they are exposed to the wind-heat, or the wind-cold enters the interior and transforms into heat, then the defensive surface is out of harmony and the lung qi fail to disperse properly. This leads to symptoms of defensive surface and the upper jiao of pulmonary system, such as fever, nasal congestion, runny nose, cough, and headache.
Based on the above reasons, the present application uses the Menthae Haplocalycis Herba, the Bombyx Batryticatus, and the Artemisia Annuae Herba which are clear and refreshing flavored, gently cooling and dispersing, and are effective in releasing Wei-defence phase pattern; as well as the Gypsum Fibrosum, the Anemarrhenae Rhizoma, and the Scutellariae Radix, which are bitter and cold flavored, and cold and cool-natured, and are effective in clearing heat from the qi level; added with Scrophulariae Radix and the Lycii Cortex, which help nourishing yin and generating fluids, draining fire and detoxifying, preventing heat from damaging yin, and have the purpose of “for every measure of body fluids preserved, there is a measure of vitality maintained”. In this way, external wind is dispersed, heat and toxins are cleared, yin fluids are preserved, and fever is rapidly reduced to aid in the pediatric patient's recovery. The combination of these components have the effect of dispersing wind and dissipating heat, clearing heat and detoxifying, generating fluids and protecting yin, function in treating the pattern involving both Wei-defence and qi phases, and treating both the surface and interior conditions, and are primarily used to removing wind and clearing heat, and detoxifying and protecting yin, so as to treating pediatric exogenous wind-heat and the pattern involving both Wei-defence and qi phases, with symptoms such as persistent high fever, sweating or scant sweating, nasal congestion, runny nose, red and swollen throat, yellow urine, dry stool, red tongue with thin white or thin yellow coating, and slippery rapid pulse, and pediatric upper respiratory tract infections with the above syndromes.
In conclusion, the traditional Chinese medicine composition provided in the present application can effectively treat pediatric wind-heat exterior conditions, significantly improve clinical symptoms and signs in pediatric patient, enhance immune function, and has a notable therapeutic effect with high safety, making it suitable for clinical promotion.
The present application also provides two preparation methods for the traditional Chinese medicine composition, which maximize the extraction of beneficial substances from the ingredients and efficiently and conveniently produce the traditional Chinese medicine composition, which facilitates the bulk production.
