Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine foot bath liquid, in particular to a method for boiling and multiple sterilizing and preserving the traditional Chinese medicine foot bath liquid. Background Art

[0002] Due to its unique pharmacological effects and abundant resources, Chinese herbal medicine has played an important role in people's daily lives. Among them, foot bath is a common health care method. People usually use Chinese herbal medicine to make foot bath liquid, and use its unique pharmacological effects to improve foot diseases or relieve foot fatigue. However, there are some problems with the existing preparation methods of Chinese herbal medicine foot bath liquid.

[0003] Existing preparation methods usually use boiling water to brew Chinese herbal medicines, but this method cannot fully extract the effective ingredients of Chinese herbal medicines, resulting in poor pharmacological effects of foot baths. The types and ratios of Chinese herbal medicines have an important impact on the effects of foot baths. However, existing methods often ignore this and are unable to adjust the ratios of various Chinese herbal medicines to achieve the best effect. Existing methods often over-boil during the boiling process, resulting in the loss of effective ingredients of the medicinal materials, which reduces the effect of the foot bath. Summary of the Invention

[0004] Based on the above-mentioned purpose, the present invention provides a method for preparing and sterilizing Chinese herbal foot bath liquid with multiple sterilization and preservation. The method takes into account the boiling method of Chinese herbal medicine, the ratio of medicinal materials, and the boiling temperature and time, effectively solves the problems existing in the prior art, and improves the effect of the foot bath liquid.

[0005] A method for preparing a Chinese medicine foot bath solution by boiling and multiple sterilization and preservation comprises the following steps:

[0006] S1: drying and crushing the Chinese herbal medicines of Centella asiatica, dried ginger, Zanthoxylum bungeanum, Rosa roxburghii, Murraya osmanthus, peach blossom, and Artemisia argyi;

[0007] S2: adding the dried Chinese herbal medicine raw materials into boiling water and boiling;

[0008] S3: After the boiled liquid is filtered, a clear liquid is obtained;

[0009] S4: Cooling the obtained clear liquid and then sterilizing it;

[0010] S5: Finally, the sterilized clear liquid is put into a packaging bag to obtain the Chinese medicine-boiled foot bath liquid.

[0011] Furthermore, the weight proportions of the centella asiatica, dried ginger, pepper, rosa roxburghii, osmanthus fragrans, peach blossom, and wormwood are as follows: centella asiatica 2%-15%, dried ginger 3%-20%, pepper 2%-10%, rosa roxburghii 3%-15%, osmanthus fragrans 5%-25%, peach blossom 2%-15%, and wormwood 4%-20%, wherein:

[0012] Centella asiatica: used to provide heat-clearing and detoxifying effects in foot baths:

[0013] Dried ginger: used to promote blood circulation and remove blood stasis in foot baths;

[0014] Sichuan peppercorns: used to provide cold-dispelling properties to foot baths;

[0015] Rosa roxburghii: used to reduce swelling and relieve pain in foot baths;

[0016] Murraya paniculata: used to provide antibacterial and anti-inflammatory effects to foot baths;

[0017] Peach Blossom: Used to provide a relaxing effect to foot baths;

[0018] Mugwort: Used to provide wind-dispelling and cold-relieving effects to foot baths.

[0019] Furthermore, the drying treatment is air-drying, and the specific air-drying time is 1 day. During the air-drying process, direct sunlight exposure is avoided to prevent the effective ingredients in the medicinal materials from being destroyed. The pulverization treatment uses a medicinal material pulverizer, and the particle size of the pulverized medicinal materials is 0.5-2 mm.

[0020] Furthermore, the boiling step in S2 is specifically as follows:

[0021] First, the dried and crushed Chinese herbal medicine raw materials need to be added to the boiled water, where the amount of water is 10-15 times that of the herbal medicine raw materials;

[0022] After adding the herbal ingredients, you need to keep the water boiling for 15-45 minutes;

[0023] During the boiling process, pay attention to regular stirring to ensure the uniform distribution of herbs in the water, thereby improving the extraction efficiency of active ingredients. The stirring speed is 15 rpm.

[0024] After boiling, you need to immediately reduce the heat to low and allow the mixture of herbs and water to cool naturally to prevent the active ingredients in the herbs from being destroyed by the sudden high temperature.

[0025] Furthermore, the filter residue in S3 is specifically:

[0026] First, remove the boiled liquid from the fire and wait for about 5-10 minutes for it to cool down naturally to prevent burns caused by excessive temperature during the slag filtration process;

[0027] Then, we use a fine-pore filter to filter the liquid medicine;

[0028] During the filtration process, squeeze the herbal residue with moderate force to extract the medicinal liquid. Do not use too much force to prevent the herbal residue from breaking and passing through the filter, resulting in a decrease in the clarity of the medicinal liquid.

[0029] Finally, the clear liquid is obtained after filtering through the filter.

[0030] Furthermore, the cooling in S4 is carried out naturally at room temperature for 30 minutes. During the cooling process, it is necessary to ensure that the container of the clear liquid remains closed to prevent external contamination.

[0031] Furthermore, the sterilization treatment in S4 is a high temperature sterilization method and an ultraviolet sterilization method, specifically:

[0032] High temperature sterilization method: put the cooled clear liquid into a pressure cooker and use high temperature to keep the temperature above 130℃ for 15 minutes;

[0033] Ultraviolet sterilization method: Place the cooled clear liquid into the ultraviolet sterilization equipment and use the bactericidal ability of ultraviolet rays for sterilization.

[0034] Furthermore, the specific steps of the packaging are:

[0035] Packaging selection: The selected packaging material needs to meet food grade or medical grade standards to ensure that it is safe, non-toxic, odorless, and will not react chemically with the foot bath solution.

[0036] Filling: The environment needs to be kept clean during the filling process to prevent secondary contamination of the foot bath liquid during the filling process.

[0037] Sealing: After filling is completed, sealing must be carried out immediately. The seal must be tight to prevent the intrusion of air or microorganisms and ensure the quality and shelf life of the product.

[0038] Outer packaging and labeling: After the sealing is completed, the product needs to be packaged. The outer packaging will provide additional protection and provide more space to print product information. Each product has a label. The label should contain information such as product name, ingredients, production date, shelf life, and usage instructions so that consumers can understand the product details.

[0039] Furthermore, the foot bath liquid further comprises an appropriate amount of a preservative, which is natural or synthetic and is used to extend the effective use period of the foot bath liquid and prevent the growth of microorganisms. Specific preservatives include sodium benzoate, sucrose, and ethylhexylglycerin. The amount of the preservative added is 1%, wherein:

[0040] Sodium benzoate: has good antibacterial properties and can effectively inhibit the growth of bacteria, yeast and mold;

[0041] Sucrose: It can achieve the antiseptic effect by inhibiting the activity of cell water;

[0042] Ethylhexylglycerin: As a commonly used preservative, it has a bactericidal effect and can also increase the stability of the product.

[0043] The present invention has the following beneficial effects:

[0044] The present invention adopts precise mixing ratios and boiling time of Chinese herbal medicines to ensure the full extraction of various active ingredients in the medicinal liquid. Specifically, we carefully select and mix seven Chinese herbal medicines, including Centella asiatica, dried ginger, Sichuan pepper, Rosa roxburghii, Murraya osmanthus, peach blossom, and Artemisia argyi. The proportion of each herbal medicine in the herbal mixture is within a specific range to ensure the extraction and utilization of its active ingredients.

[0045] The present invention replaces the conventional boiling water brewing method by boiling, effectively extracts the effective ingredients of Chinese herbal medicines, thereby making the foot bath liquid more effective. In addition, we further ensure the quality and safety of the foot bath liquid through a series of steps such as filtering the liquid, cooling and sterilizing. Among them, the sterilization treatment adopts high temperature sterilization or ultraviolet sterilization, which can kill possible microorganisms and avoid damage to the effective ingredients of Chinese herbal medicines.

[0046] During the packaging process, the present invention pays attention to the label information of the product, including the product name, ingredients, production date, shelf life, usage instructions, etc., so that consumers can clearly understand the detailed information of the product and facilitate their correct use. At the same time, the materials of the packaging bags or bottles used meet food grade or medical grade standards, ensuring the safety of the product and improving the grade of the product, making it more competitive in the market.

[0051] Example 1:

[0052] like Figure 1 As shown, a method for preparing a Chinese medicine foot bath solution and performing multiple sterilization and preservation comprises the following steps:

[0053] S1: drying and crushing the Chinese herbal medicines of Centella asiatica, dried ginger, Zanthoxylum bungeanum, Rosa roxburghii, Murraya osmanthus, peach blossom, and Artemisia argyi;

[0054] S2: adding the dried Chinese herbal medicine raw materials into boiling water and boiling;

[0055] S3: After the boiled liquid is filtered, a clear liquid is obtained;

[0056] S4: Cooling the obtained clear liquid and then sterilizing it;

[0057] S5: Finally, the sterilized clear liquid is put into a packaging bag to obtain the Chinese medicine-boiled foot bath liquid.

[0058] The weight proportions of the components of Centella asiatica, dried ginger, pepper, roxburghii, Murraya osmanthus, peach blossom, and wormwood are as follows: Centella asiatica 12%, dried ginger 13%, pepper 13%, roxburghii 13%, Murraya osmanthus 13%, peach blossom 12%, and wormwood 13%, wherein:

[0059] Centella asiatica: used to provide heat-clearing and detoxifying effects in foot baths:

[0060] Dried ginger: used to promote blood circulation and remove blood stasis in foot baths;

[0061] Sichuan peppercorns: used to provide cold-dispelling properties to foot baths;

[0062] Rosa roxburghii: used to reduce swelling and relieve pain in foot baths;

[0063] Murraya paniculata: used to provide antibacterial and anti-inflammatory effects to foot baths;

[0064] Peach Blossom: Used to provide a relaxing effect to foot baths;

[0065] Mugwort: Used to provide wind-dispelling and cold-relieving effects to foot baths.

[0066] The drying process is air-drying, and the specific air-drying time is 1 day. During the air-drying process, avoid direct sunlight to prevent the effective ingredients in the medicinal materials from being destroyed. The crushing process uses a medicinal material crusher, and the particle size of the crushed medicinal materials is 1mm to facilitate the extraction of effective ingredients.

[0067] The boiling steps in S2 are as follows:

[0068] First, the dried and pulverized Chinese herbal medicines are added to boiling water, with the amount of water being 10 times that of the herbal material. This is to fully extract the active ingredients from the herbs and also to leave enough for the subsequent filtration step.

[0069] After adding the herbal ingredients, the water needs to be kept boiling for 30 minutes. This time is set mainly to allow the active ingredients in the herbs to be fully extracted into the water. If the boiling time is too short, the active ingredients in the herbs may not be fully extracted and the desired effect cannot be achieved. On the contrary, if the boiling time is too long, some active ingredients may be destroyed, which will also affect the effect.

[0070] During the boiling process, pay attention to regular stirring to ensure the uniform distribution of herbs in the water, thereby improving the extraction efficiency of active ingredients. The stirring speed is 15 rpm.

[0071] After boiling, you need to immediately reduce the heat to low and allow the mixture of herbs and water to cool naturally to prevent the active ingredients in the herbs from being destroyed by the sudden high temperature.

[0072] The filter residue in S3 is specifically:

[0073] First, remove the boiling liquid from the fire and wait for 10 minutes for it to cool down naturally to prevent burns caused by excessive temperature during the slag filtering process;

[0074] Then, we use a fine-pore filter to filter the liquid medicine. When choosing the filter, the pore size needs to be able to effectively block the drug residue, but at the same time it must be fine enough to allow the liquid medicine to pass through smoothly. During the filtration process, we must ensure that the filter is clean and try to make all the liquid medicine pass through the filter.

[0075] During the filtration process, squeeze the herbal residue with moderate force to extract the medicinal liquid. Do not use too much force to prevent the herbal residue from breaking and passing through the filter, resulting in a decrease in the clarity of the medicinal liquid.

[0076] Finally, what is obtained after filtering through the filter is the clear liquid, which contains the active ingredients of herbal medicine and is the main ingredient for making foot bath solution made from traditional Chinese medicine.

[0077] The cooling in S4 is carried out naturally at room temperature for 30 minutes. During the cooling process, it is necessary to ensure that the container of the clear liquid remains closed to prevent external contamination.

[0078] The sterilization treatment in S4 is high temperature sterilization method, specifically:

[0079] High temperature sterilization method: put the cooled clear liquid into a pressure cooker, use high temperature, keep the temperature above 130℃ for 15 minutes.

[0080] The specific steps of packaging are:

[0081] Packaging selection: The selected packaging material needs to meet food grade or medical grade standards to ensure that it is safe, non-toxic, odorless, and will not react chemically with the foot bath solution.

[0082] Filling: The environment needs to be kept clean during the filling process to prevent secondary contamination of the foot bath liquid during the filling process.

[0083] Sealing: After filling is completed, sealing must be carried out immediately. The seal must be tight to prevent the intrusion of air or microorganisms and ensure the quality and shelf life of the product.

[0084] Outer packaging and labeling: After the sealing is completed, the product needs to be packaged. The outer packaging will provide additional protection and provide more space to print product information. Each product has a label that should contain information such as product name, ingredients, production date, shelf life, and usage instructions.

[0085] The foot bath liquid also includes an appropriate amount of preservative, which is natural or synthetic and is used to extend the effective use period of the foot bath liquid and prevent the growth of microorganisms. The specific preservative is sodium benzoate, and the added amount of the preservative is 11%. Among them, sodium benzoate has good antibacterial properties and can effectively inhibit the growth of bacteria, yeast and mold.

[0086] Example 2:

[0087] The difference from Example 1 is that, first, the Chinese herbal medicine raw materials of 15% Centella asiatica, 15% dried ginger, 10% Zanthoxylum bungeanum, 10% Rosa roxburghii, 10% Murraya osmanthus, 15% peach blossom, and 15% Artemisia argyi are dried and crushed, the drying process is air-dried for 1 day, and the particle size of the crushed medicinal materials is 1.5 mm;

[0088] Add the dried Chinese herbal medicine to the boiling water, with the amount of water being 12 times that of the herbal medicine. Keep the water boiling for 35 minutes, stirring regularly at a speed of 15 rpm. After boiling, immediately reduce the heat to low and let it cool naturally.

[0089] After the boiled liquid is cooled naturally for 10 minutes, it is filtered through a fine-mesh filter, the herbal residue is squeezed out, and the liquid is extracted to obtain a clear liquid;

[0090] The obtained clear solution was cooled naturally at room temperature for 30 minutes and then sterilized using ultraviolet sterilization;

[0091] Adding a preservative to the cooled and sterilized clear solution, wherein the preservative is sucrose in an amount of 10%;

[0092] The foot bath liquid after adding the preservative is put into a food-grade packaging bag, which is sealed, and the outer packaging and labeling are completed to obtain the traditional Chinese medicine boiled foot bath liquid.

[0093] Example 3:

[0094] The difference from Example 1 is that first, the Chinese herbal medicine raw materials of 18% Centella asiatica, 17% dried ginger, 8% Zanthoxylum bungeanum, 8% Rosa roxburghii, 8% Murraya osmanthus, 18% peach blossom, and 17% Artemisia argyi are dried and crushed, the drying process is air-dried for 1 day, and the particle size of the crushed medicinal materials is 1.5 mm;

[0095] Add the dried Chinese herbal medicine to boiling water, with the amount of water being 15 times the amount of the herbal medicine. Keep the water boiling for 45 minutes, stirring regularly at a speed of 15 rpm. After boiling, immediately reduce the heat to low and allow to cool naturally.

[0096] After the boiled liquid is cooled naturally for 10 minutes, it is filtered through a fine-mesh filter, the herbal residue is squeezed out, and the liquid is extracted to obtain a clear liquid;

[0097] The obtained clear solution was cooled naturally at room temperature for 30 minutes and then sterilized using ultraviolet sterilization;

[0098] Adding a preservative to the cooled and sterilized clear solution, wherein the preservative is 6% hexyl glycerin;

[0099] The foot bath liquid after adding the preservative is put into a food-grade packaging bag, which is sealed, and the outer packaging and labeling are completed to obtain the traditional Chinese medicine boiled foot bath liquid.
