Description

Technical Field

[0001] This invention relates to the field of feminine hygiene products, and in particular to a traditional Chinese medicine composition, a preparation method thereof, and a feminine intimate care gel. Background Technology

[0002] The female private parts are important organs for metabolism and secretion. They are affected by internal and external factors, and the environment is relatively complex, making them highly susceptible to infection by various germs and diseases. This not only affects women's physical and mental health and quality of life, but also makes the skin in the private parts more sensitive, prone to various inflammations or simple skin itching, requiring special nourishment and care.

[0003] Currently, commercially available feminine hygiene products fall into the following categories: One type uses antibiotics and other chemical bactericides. While these products have a high bactericidal rate and can kill a large number of pathogenic bacteria in the vagina in a short period, they also kill resident and beneficial bacteria, disrupting the vaginal microecological balance and reducing the vagina's resistance to pathogens with long-term use. Another type typically incorporates traditional Chinese medicine extracts, containing ingredients such as Sophora flavescens, Phellodendron chinense, and Cnidium monnieri, which can irritate the vaginal mucosa. Nano-silver antibacterial agents and colloidal silver antibacterial agents suffer from poor stability (prone to discoloration and acidity changes), and with stricter environmental regulations on nano-silver, the use of nano-silver products is severely limited. Therefore, developing a highly effective, gentle feminine hygiene ingredient that can maintain the vaginal microecological balance has become urgently needed. Summary of the Invention

[0004] In view of this, in order to solve the problem that current feminine hygiene products disrupt the balance of vaginal flora and irritate the vaginal mucosa, the purpose of this invention is to provide a highly effective, gentle traditional Chinese medicine composition, preparation method, and a feminine hygiene gel that can maintain the balance of the vaginal microecology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] This invention provides a traditional Chinese medicine composition prepared from raw materials comprising the following parts by weight: 25-40 parts of Lophatherum gracile, 20-30 parts of Houttuynia cordata, 12-20 parts of Artemisia capillaris, 10-15 parts of Mentha haplocalyx, and 15-25 parts of Centella asiatica.

[0007] This invention provides an extraction method for the aforementioned traditional Chinese medicine composition, comprising the following steps:

[0008] (1) Mix the Lophatherum gracile, Houttuynia cordata, Artemisia capillaris, Mentha haplocalyx, and Centella asiatica, grind them into powder, and then sift them.

[0009] (2) After soaking the sieved powder in ethanol, a first reflux extraction was performed to obtain the first extract and the residue.

[0010] (3) Mix the first residue with ethanol and perform a second reflux extraction to obtain the second extract;

[0011] (4) Combine the first extract and the second extract, and concentrate by rotary evaporation to obtain the extract of the traditional Chinese medicine composition.

[0012] Preferably, the soaking time in step (2) is 0.5 to 1 hour, and the volume fraction of ethanol extracted by the first reflux is 40 to 60%.

[0013] Preferably, the weight of ethanol in step (2) is 8 to 12 times that of the Chinese herbal raw material, and the time for the first reflux extraction and the second reflux extraction is independently 1.5 to 2.5 hours.

[0014] Preferably, the weight of ethanol in step (3) is 5 to 10 times that of the Chinese herbal raw material, and the volume fraction of ethanol in the second reflux extraction is 60 to 80%.

[0015] Preferably, the vacuum degree of the vacuum evaporation concentration in step (4) is 600-1000 Pa, the temperature of the rotary evaporation concentration is 65-75°C, the rotation speed of the vacuum evaporation concentration is 80-120 rpm, and the rotary evaporation concentration is carried out to a crude drug concentration of 0.3-0.6 g / mL.

[0016] The present invention also provides the application of the traditional Chinese medicine composition in the preparation of a feminine hygiene medicine.

[0017] Preferably, the drug includes ointment, gel, or treatment solution.

[0018] The present invention also provides a feminine hygiene gel comprising the following components in weight percentage: 20-30% of the extract of the traditional Chinese medicine composition of claim 2, 5-10% of glycerin, 0.8-1.2% of carbomer, 0.3-0.5% of triethanolamine, and the remainder being water.

[0019] The present invention also provides a method for preparing the aforementioned feminine hygiene gel, comprising the following steps:

[0020] S1. Mix carbomer and glycerin, pour into water while stirring, heat to 75-85°C and continue stirring until carbomer is completely dissolved to obtain the first mixture;

[0021] S2. After stirring and cooling the first mixture to 40-45°C, mix it with the extract of the traditional Chinese medicine composition and stir to obtain the second mixture;

[0022] S3. After defoaming the second mixture, mix it with triethanolamine and stir to obtain a feminine hygiene gel.

[0061] Comparative Example 1

[0062] Unlike Example 1, Lophatherum gracile was replaced with Sophora flavescens.

[0063] Comparative Example 2

[0064] Unlike Example 1, no houttuynia cordata was added.

[0065] Comparative Example 3

[0066] Unlike Example 1, Centella asiatica was not added.

[0067] Experimental Example 1: Vaginal Mucosal Stimulation Test

[0068] Eighteen ordinary female New Zealand rabbits, weighing 2–2.5 kg, were randomly divided into 6 groups of 3 rabbits each. Before the experiment, the animals' vaginas were checked for discharge to ensure there was no congestion or edema. The animals were fixed in a supine position, and the vaginal gel was gently inserted 4–5 cm into the vagina after being moistened with physiological saline. 2.5 mL of the feminine hygiene gel from Examples 1–3 and Comparative Examples 1–3 was injected using a syringe. The presence of congestion or edema was observed after 24 hours. The experimental results are shown in Table 1.

[0069] Table 1. Sample Stimulation Status

[0070] Group sample Stimulation 1 Example 1 none 2 Example 2 none 3 Example 3 none 4 Comparative Example 1 Two were congested, and one was edematous. 5 Comparative Example 2 none 6 Comparative Example 3 One animal with mild edema

[0071] As shown in Table 1, the feminine hygiene gels prepared in Examples 1-3 of this invention did not cause vaginal congestion or edema in New Zealand rabbits. In Comparative Example 1, after replacing Lophatherum gracile with Sophora flavescens, the vaginal irritation increased, and congestion and edema occurred. In Comparative Example 2, no Houttuynia cordata was added, and no vaginal irritation occurred. In Comparative Example 3, no Centella asiatica was added, which resulted in mild vaginal edema in one New Zealand rabbit.

[0072] Experiment Example 2: Antibacterial Experiment

[0073] Test strains: Escherichia coli, Staphylococcus aureus, Candida albicans, fungi, and Candida vaginalis. 8g of the feminine hygiene gels prepared in Examples 1-3 and Comparative Examples 1-3 were dissolved in 10g of anhydrous ethanol, and then deionized water was added to bring the volume to 100ml. A 0.1g / ml ethanol solution was used as a blank control. The experiment was conducted according to the national standard GB15979-2002. The antibacterial rate test results after 30 minutes of action are shown in Table 2.

[0074] Table 2 Results of Antibacterial Rate Test of Samples

[0075]

[0076]

[0077] Table 2 shows that the feminine hygiene gels prepared in Examples 1-3 all exhibited antibacterial rates exceeding 90% against Escherichia coli, Staphylococcus aureus, Candida albicans, fungi, and Candida vaginalis. Replacing Lophatherum gracile with Sophora flavescens maintained the antibacterial activity at roughly the same level, but increased irritation to the vaginal mucosa. Comparative Example 2, without Houttuynia cordata, and Comparative Example 3, without Centella asiatica, showed significantly reduced antibacterial activity, indicating a synergistic effect among the various herbal components in this invention.

[0078] Experimental Example 3: Clinical Efficacy Verification

[0079] One hundred and eighty female volunteers aged 20-50 years with vaginitis were randomly divided into six groups of 30 each. Each volunteer applied a feminine hygiene gel into the vagina before bedtime, once daily for 15 consecutive days. The number of cases in different groups showing improvement in symptoms such as vulvar inflammation, itching, redness, and odor was recorded. The results are shown in Table 3.

[0080] Table 3 Number of cases showing improvement in genital problems

[0081] sample Inflammation (example) Itching (example) Redness and swelling (example) Odor (example) Example 1 27 25 24 28 Example 2 25 23 23 24 Example 3 28 27 26 28 Comparative Example 1 27 23 25 27 Comparative Example 2 15 19 16 20 Comparative Example 3 17 18 10 18

[0082] As shown in Table 3, the feminine hygiene gels prepared in Examples 1-3 of this invention have significant effects, effectively preventing and alleviating vaginal diseases, and exhibiting a certain degree of repair. Example 4, by replacing Lophatherum gracile with Sophora flavescens, also achieved a therapeutic effect comparable to that of this invention; however, the feminine hygiene gel of this invention is gentler and reduces irritation to the vaginal mucosa. Comparative Examples 2 and 3, which did not contain Houttuynia cordata and Centella asiatica respectively, showed significantly reduced treatment of inflammation and repair effects, indicating that the components in this invention have a synergistic effect, effectively cleaning the vagina, relieving discomfort, inhibiting bacterial growth, repairing the vaginal mucosa, and relieving itching and odor.

[0083] As can be seen from the above embodiments, the present invention provides a traditional Chinese medicine composition and a feminine hygiene gel. The feminine hygiene gel can effectively clean the private parts, relieve discomfort, inhibit bacterial growth, repair the private mucosa, and relieve itching and odor.

[0084] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
