Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and in particular relates to a traditional Chinese medicine composition with soothing and anti-allergic effects, and a preparation method and application thereof. Background Art

[0002] In recent years, as consumers' interest in the safety and naturalness of skincare products continues to rise, the research and development of anti-allergic cosmetics has gradually shifted from chemically synthesized ingredients to plant-derived active ingredients. However, current technology still faces numerous bottlenecks: While chemical anti-allergic agents (such as ceramide NP, bisabolol, and dipotassium glycyrrhizate) can quickly take effect, long-term use can easily damage the skin barrier and even cause dependent dermatitis. Single plant extracts (such as Phellodendron amurense and Sophora flavescens), while relatively safe, have limited anti-allergic effects and a single target, making them ineffective in addressing complex allergic symptoms, particularly in alleviating itching. This highlights the limited efficacy of single ingredients.

[0003] Some compound compositions attempt to enhance their anti-allergic effects through the combination of multiple ingredients, but these formulations suffer from issues such as insufficient naturalness or unclear synergistic mechanisms. For example, invention patent CN108186472A discloses an anti-allergic soothing composition primarily composed of a first active ingredient (Sophora flavescens root extract, Glycyrrhiza uralensis root extract, and Scutellaria baicalensis root extract), Stephania tetrandra extract, theanine, and epigallocatechin gallate (EGCG). While this composition contains multiple natural extracts, it also contains chemical or semi-synthetic ingredients such as theanine and EGCG, which may irritate sensitive skin and contradict the market trend of "pure and natural."

[0004] For example, invention patent CN105902447B discloses a composition with anti-allergic and soothing effects. The composition is composed of plant extracts (Mirabilis jalapa, Ophiopogon japonicus, Sophora flavescens, Opuntia cochinchinensis, Mentha piperita, Portulaca oleracea, Nepeta tenuifolia, Aloe vera, and Pulsatilla chinensis), trehalose, 1,3-propylene glycol, and water. Although this anti-allergic composition contains natural ingredients such as Sophora flavescens and Portulaca oleracea, the added chemical excipients (trehalose and 1,3-propylene glycol), particularly 1,3-propylene glycol, may not be friendly to sensitive skin, limiting its application. Furthermore, the patent briefly mentions the inhibition of histamine release and hyaluronidase activity, without further elaboration on the synergistic effects of the various ingredients.

[0005] Invention patent CN117159428B discloses a composition with soothing, anti-allergic, and anti-itching properties. The composition contains hydroxyphenylpropionamide benzoic acid, matrine, purslane extract, and dimethyl isosorbide. While emphasizing the synergistic effect of multiple components, the presence of synthetic or semi-synthetic substances raises questions about its natural safety. Similarly, invention patent CN101732205B discloses a skin care composition that soothes allergic skin, provides anti-inflammatory and anti-irritation benefits. This composition also relies on chemically synthesized ingredients such as allantoin and dipotassium glycyrrhizate, making it difficult to accurately assess the actual contribution of natural extracts.

[0006] Furthermore, some traditional Chinese medicine formulas also have significant flaws. For example, invention patent CN103623112B discloses a traditional Chinese medicine composition for treating skin itching. While the disclosed traditional Chinese medicine composition for treating skin itching contains natural ingredients such as Phellodendron amurense and Sophora flavescens, it incorporates as many as 16 herbs. The redundant composition makes it difficult to clearly define the effects of each component, obscuring its mechanism of action and failing to reveal the synergistic effects between the ingredients. Furthermore, its preparation process relies solely on the traditional method of boiling and removing residue, resulting in low utilization of the active ingredients.

[0007] Therefore, developing an anti-allergic composition that is naturally safe, highly effective, and can achieve multi-target synergistic effects has become a key issue that the industry urgently needs to address. Summary of the Invention

[0008] The purpose of the present invention is to overcome the above-mentioned defects and deficiencies in the prior art and to provide a natural soothing and anti-allergic Chinese medicine composition that is both natural and safe, highly effective, and has multi-target synergistic effects, so as to solve the key problems in the prior art, such as the high irritation of chemical anti-allergic agents, the insufficient efficacy of single plant extracts, the lack of naturalness of compound compositions, and the unclear synergistic mechanism.

[0009] The second object of the present invention is to provide a method for preparing the traditional Chinese medicine composition with soothing and anti-allergic effects.

[0010] The third object of the present invention is to provide an application of the traditional Chinese medicine composition having soothing and anti-allergic effects.

[0011] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0012] A traditional Chinese medicine composition with soothing and anti-allergic effects, the traditional Chinese medicine composition consisting of a Sophora flavescens extract, a Phellodendron amurense extract, and a Herba Lycopodii extract in a mass ratio of (2-4): (1-2): (0.5-1); the Sophora flavescens extract is a Sophora flavescens total alkaloid extract; the Phellodendron amurense extract is a Phellodendron amurense total alkaloid extract; and the Herba Lycopodii extract is a Herba Lycopodii flavonoid and phenolic acid active substances.

[0013] Sophora flavescens is a plant of the genus Sophora flavescens in the Leguminosae family ( Sophora flavescensThe dried root of Sophora flavescens (Ait.) is primarily produced in North, East, and Northwest my country. It is cold in nature and bitter in flavor, purifying the heart, liver, stomach, large intestine, and bladder meridians. It has the effects of clearing heat and dampness, killing insects and relieving itching, and promoting diuresis and relieving stranguria. Its core active ingredients are alkaloids (matrine and oxymatrine) and flavonoids (matrine and isomatrine). Matrine can inhibit pathogens such as Staphylococcus aureus and Shigella dysenteriae, modulate immunity, and fight arrhythmias. Oxymatrine reduces inflammation by inhibiting the NF-κB pathway and is widely used clinically for treating damp-heat diarrhea, eczema and pruritus, jaundice, and vaginal trichomoniasis. Existing sophora flavescens extracts are alkaloids extracted from the plant Sophora flavescens, a member of the genus Sophora in the Leguminosae family. They appear as yellow to brown granules or powders and have a bitter taste. Modern research has shown that sophora flavescens extracts have inhibitory effects on hepatitis B virus, skin fungi, and tumor cells (such as HepG2), and can also slow the progression of liver fibrosis by blocking the TGF-β signaling pathway. External use often involves fumigation and washing with a decoction to treat scabies and genital swelling. Sophora flavescens combines traditional heat-clearing properties with modern anti-inflammatory and anti-tumor potential, making it an important resource in the fields of antimicrobial and immunomodulatory Chinese medicine.

[0014] Phellodendron chinense is a plant of Rutaceae family ( Phellodendron chinense The dried bark of the Chinese phellodendron chinense (Phellodendron chinense), primarily produced in Sichuan, Hubei, and Guizhou, is cold in nature and bitter in flavor, entering the kidney and bladder meridians. It has the effects of clearing heat and dampness, purging fire and detoxifying, and relieving asthenic fever. Its core active ingredients are alkaloids such as berberine, jatrorrhizine, and palmatine. Berberine exerts broad-spectrum antibacterial effects (such as against Staphylococcus aureus and Escherichia coli) by inhibiting bacterial DNA gyrase and disrupting cell membranes. Terpenoids such as phellodendron ketone and phellodendron lactone exhibit anti-inflammatory, hypoglycemic, and immunomodulatory activities. It is commonly used clinically for damp-heat diarrhea, jaundice, dark urine, and bone steaming and night sweats caused by yin deficiency and fire excess (e.g., Zhibai Dihuang Wan). It is also used topically to treat eczema, burns, and sores. In the prior art, phellodendron chinense extract refers to a substance extracted from the dried bark of the Rutaceae plant, Phellodendron chinense or Phellodendron amurense. Modern research has shown that phellodendron chinense extract can inhibit the NF-κB pathway, reduce inflammation, and assist in the treatment of diabetes and immune-related diseases. Huangbai has both classic medicinal effects and modern pharmacological basis, and is an important resource in the field of antibacterial and anti-inflammatory traditional Chinese medicine.

[0015] Monkey Earrings ( Pithecellobium clypeariaBenth., also known as the savory tree and dragon wood, is a plant of the genus Mimosoideae, subfamily Mimosoideae, in the Fabaceae family. It is primarily distributed in southern China and Southeast Asia. Its dried leaves, stems, and branches are used as medicine, first recorded in the Compendium of Materia Medica. It is slightly cold in nature, bitter and astringent in taste, and enters the spleen, stomach, and liver meridians. It has the effects of clearing heat and detoxifying, cooling blood and reducing swelling, and stopping diarrhea and healing sores. It is commonly used in folk medicine to treat burns, eczema, and purulent wounds. Modern research shows that Benth. is primarily composed of flavonoids (quercetin, kaempferol, and their glycosides), phenolic acids (gallic acid, ethyl gallate), triterpenes, and phenylpropanoids. Flavonoids exert antibacterial and antiviral effects by disrupting bacterial membrane permeability and inhibiting viral replication. Gallic acid exhibits significant anti-inflammatory activity, inhibiting histamine release and the expression of inflammatory factors. Pharmacological studies have confirmed its multiple activities, including antiviral, antibacterial, anti-inflammatory, antioxidant, and immunomodulatory. It is particularly effective in inhibiting the release of influenza and herpes viruses and inflammatory factors. Monkey earrings have shown unique value in the field of anti-drug resistant bacterial infection and are known as "green antibiotics". The monkey earring extract of the present invention contains flavonoids and phenolic acid active substances.

[0016] By scientifically optimizing the ratio of extracts from Phellodendron amurense, Sophora flavescens, and Herba Ostreae, this invention leverages the multiple anti-inflammatory, antibacterial, and repairing properties of each ingredient. This method achieves multi-target synergistic efficacies: inhibiting hyaluronidase activity, regulating inflammatory factors, and blocking itch signals. The synergistic effect of these three ingredients delivers rapid itch relief and strong soothing effects. This effectively overcomes the technical shortcomings of existing anti-allergic agents, such as their lack of naturalness, limited efficacy, and unclear synergistic mechanisms.

[0028] Furthermore, the monkey earring extract is extracted using an alcohol solvent, the extract is acid precipitated, the supernatant is adjusted to neutral, purified by a macroporous resin, and eluted with a solvent to obtain the extract.

[0029] Preferably, the alcohol solvent extraction is performed by using 65% to 75% ethanol as a solvent for the monkey earrings at a material-liquid ratio of 1:10 to 20 (w / v), reflux extraction at 75° C. to 85° C. for multiple times, and combining the extracts.

[0030] Preferably, the extract is acid-precipitated and the supernatant is adjusted to neutral by adjusting the pH of the extract to 3-4, allowing the extract to settle, centrifuging to remove the precipitate, and adjusting the supernatant to neutral.

[0130] Test Example 1 Skin irritation test

[0131] The method and results of the skin irritation test on the Chinese herbal soothing and anti-allergic compositions involved in Examples 1 to 6 are as follows:

[0132] 1. Test method basis: In accordance with the "Skin Irritation Test Method" in the "Technical Specifications for Safety of Cosmetics (2015 Edition)".

[0133] 2. Experimental Principle: The test substance is applied once to the skin of the test animal. At specified time intervals, the degree of local irritation to the animal's skin is observed and scored. A self-control is used to evaluate the irritation of the test substance to the skin.

[0134] 3. Test Samples and Animals: The test substances were the soothing and anti-allergic Chinese herbal compositions described in Examples 1-6. Weigh 1.000 g of each of these compositions, dissolve them in purified water, and dilute to 1000 mL. The test animals were standard New Zealand white rabbits purchased from Zorba Health Technology (Guangzhou) Co., Ltd.

[0135] 4. Experimental steps:

[0136] 4.1 Eighteen white New Zealand rabbits were randomly divided into six groups, with three rabbits in each group, which were respectively the groups 1 to 6 of Examples.

[0137] 4.2 About 24 hours before the test, trim the hair on both sides of the New Zealand rabbit's spine without damaging the epidermis. The hair removal area should be approximately 3 cm × 3 cm on the left and right sides.

[0138] 4.3 Apply approximately 0.5 mL of the test substance directly to the skin. Cover with two layers of gauze (2.5 cm × 2.5 cm) and a layer of cellophane, and secure with non-irritating adhesive tape and a bandage. Use the other side of the skin as a control. Use an occlusive test with a 4-hour application period. After the test, remove any remaining test substance with warm water.

[0139] 4.4 Observe the skin reaction at the application site 1, 24, 48, and 72 hours after removal of the test substance and score the skin reaction according to Table 1. The comprehensive evaluation is based on the average score of the test animals, and the skin irritation intensity is determined according to Table 2 based on the average of the highest scores at each observation time point of 24, 48, and 72 hours.

[0142] Table 2 Skin irritation intensity classification

[0143]

[0144] 5. Results and Analysis

[0145] Within 1 to 72 hours after administration of the soothing and anti-allergic Chinese herbal compositions of the present invention, no erythema or edema was observed on the skin of the New Zealand rabbits. According to the skin irritation intensity ratings in Table 2, the soothing and anti-allergic Chinese herbal compositions of the present invention were non-irritating to the skin.

[0146] Test Example 2 Soothing Efficacy Test

[0147] The soothing efficacy test was performed on Examples 1 to 6 and Comparative Examples 1 to 18.

[0148] 1. Method basis: The test was conducted according to the HMC-W1-029 hyaluronidase inhibition rate.

[0149] 2. Experimental Principle: Hyaluronic acid, as one of the main components of the cell matrix and interstitial tissue, is widely present in the cell matrix and plays an important role in maintaining skin moisture and elasticity and protecting the skin's barrier function. Hyaluronidase degrades hyaluronic acid. Inhibiting hyaluronidase activity can effectively reduce hyaluronic acid degradation, thereby reducing the release of histamine and inflammatory factors, exerting a soothing and anti-allergic effect. The hyaluronidase inhibition test uses hyaluronic acid as a substrate and determines the soothing efficacy of cosmetic ingredients by detecting their inhibition of hyaluronidase activity. Because inhibiting hyaluronidase activity can maintain the content and normal function of hyaluronic acid and maintain normal physiological activities of the skin, the hyaluronidase inhibition rate can be used as an indicator to evaluate the effectiveness of soothing ingredients. The higher the inhibition rate, the stronger the soothing activity.

[0150] 3. Reagents: Hyaluronidase BR, 300U-500U / mg, purchased from Yuanye Biotechnology; other reagents were of analytical grade.

[0151] 4. Experimental steps:

[0152] 4.1 Solution preparation

[0153] (1) Acetate buffer solution (pH 5.6): Take 1155 μL of glacial acetic acid, dilute to 100 mL with ultrapure water, mix thoroughly, and take 4.8 mL of the solution as solution A. Weigh 2.72 g of sodium acetate crystals, dissolve in ultrapure water, and dilute to 100 mL. Mix thoroughly, and take 45.2 mL of the solution as solution B. Combine solutions A and B, dilute to 100 mL with ultrapure water, and mix thoroughly. Accurately measure the pH value and adjust the pH to 5.6 using solution A or B.

[0154] (2) Hyaluronidase solution: Weigh 0.0100 g of hyaluronidase and place it in a beaker. Add 4 mL of the prepared acetate buffer solution and allow it to fully dissolve.

[0155] (3) Sodium hyaluronate solution (0.5 mg / mL): Weigh 0.01 g of sodium hyaluronate and place it in a beaker. Add 20 mL of acetic acid buffer solution and stir until completely dissolved.

[0156] (4) Ehrlich reagent: Weigh 0.8 g of p-dimethylaminobenzaldehyde and dissolve it in a mixture of 15 mL of concentrated hydrochloric acid and 15 mL of anhydrous ethanol.

[0157] (5) Sodium carbonate solution (1.0 mol / L): Weigh 5.3 g of sodium carbonate, dissolve it in ultrapure water, and dilute to 50 mL.

[0158] (6) Acetylacetone solution: Take 3.5 mL of acetylacetone and dissolve it in 50 mL of 1.0 mol / L sodium carbonate solution. The solution must be prepared immediately before use.

[0159] (7) Calcium chloride solution (0.25 mmol / L): Weigh 0.02775 g of calcium chloride, dissolve it in ultrapure water and dilute to 1000 mL.

[0160] (8) Sodium hydroxide solution (0.4 mol / L): Weigh 1.6 g of sodium hydroxide, dissolve it in ultrapure water and dilute to 100 mL.

[0161] (9) Dipotassium glycyrrhizate solution: Weigh 3.000 g of dipotassium glycyrrhizate, dissolve it in pure water and dilute to 100 mL.

[0162] (10) Solution of Chinese herbal soothing and anti-allergic composition: 1.000 g of each of the Chinese herbal soothing and anti-allergic composition of Examples 1 to 6 and Control Examples 1 to 18 were weighed, dissolved in pure water, and fixed to 1000 mL.

[0163] 4.2 Determination of hyaluronidase activity inhibition rate

[0164] Select Examples 1 to 6 and Comparative Examples 1 to 18 as samples and dipotassium glycyrrhizate solution as a positive control to perform the following operations:

[0165] First, 0.1 mL of 0.25 mmol / L calcium chloride solution and 0.5 mL of hyaluronidase solution were mixed and incubated at 37°C for 20 minutes. Next, 0.5 mL of sample solution was added and incubated at 37°C for another 20 minutes. Subsequently, 0.5 mL of sodium hyaluronate solution was added and incubated at 37°C for 30 minutes before being allowed to stand at room temperature for 5 minutes. Next, 0.1 mL of 0.4 mol / L sodium hydroxide solution and 0.5 mL of acetylacetone solution were added in sequence. The mixture was heated in a boiling water bath for 15 minutes and then quickly cooled in ice water for 5 minutes. Finally, 1.0 mL of Ehrlich's reagent was added and diluted with 3.0 mL of anhydrous ethanol. The mixture was allowed to stand at room temperature for 30 minutes to allow for full color development. The absorbance at a wavelength of 528 nm was measured using a spectrophotometer.

[0166] 4.3 Results Analysis

[0167] Hyaluronidase inhibition rate (%) = [(AB)-(CD)] / (AB)×100%

[0168] Where:

[0169] A is the absorbance value of the blank group, which means that the sample solution was replaced by acetate buffer solution;

[0170] B is the absorbance value of the blank control group, which refers to the use of acetate buffer solution instead of sample solution and enzyme solution;

[0171] C is the absorbance value of the sample group;

[0172] D is the absorbance value of the sample control group, which means that the enzyme solution is replaced by acetate buffer solution.

[0173] The data results are shown in Table 3, and the statistical analysis is shown in Tables 4 and 5.

[0177]

[0178] Table 5 Comparison of key indicators

[0179]

[0180] A comparison of the overall data distribution shows that the inhibition rates of the Examples (TCM anti-allergic compositions) were outstanding, ranging from 67.68% to 69.79%, with a mean of 68.57% ± 1.03%. The standard deviation was small, demonstrating high stability. The inhibition rates of all samples were higher than those of the positive control (58.61%) and the comparative example group. The inhibition rate of the positive control group (dipotassium glycyrrhizate), serving as a reference standard for chemical soothing ingredients, was 58.61% ± 2.05%. The inhibition rates of the comparative example group ranged from 31.97% to 51.45%, with a mean of 41.82% ± 5.46%. The standard deviation was large, with significant fluctuations. Most samples had inhibition rates below 45%, with only comparative examples 13 to 18 approaching or slightly exceeding 50%, but these rates were still lower than those of the Examples and the positive control.

[0181] A significant difference analysis further validated the advantages of the TCM anti-allergic composition. In a t-test comparing the examples and the positive control, the mean difference between the two reached 9.96%, with a t-value of ≈8.23 (df=11, p<0.001), a highly significant difference. This indicates that the TCM anti-allergic composition significantly outperformed the positive control, a chemical soothing ingredient. A variance analysis between the examples and the comparative example groups revealed a between-group variance of 225.31, a within-group variance of 18.24, and an F-value of ≈12.35 (p<0.001), indicating a highly significant difference in means. The effect size analysis yielded a Cohen's d of 2.31 (a large effect size), demonstrating that the TCM anti-allergic composition not only had a significantly higher inhibition rate than the comparative example group, but also demonstrated a significant difference in actual efficacy.

[0182] Comparison of key indicators revealed that the traditional Chinese medicine anti-allergic composition demonstrated significant advantages across multiple core parameters. The sample size for the example was 6, with a mean inhibition rate of 68.57% ± 1.03%, a minimum of 67.68%, a maximum of 69.79%, and a median of 68.48%. This mean inhibition rate was 9.96% higher than the positive control (58.61% ± 2.05%) and 26.75% higher than the mean of the control group (41.82% ± 5.46%). In terms of data fluctuation, the standard deviation of the example was only 1.03%, demonstrating stability far exceeding the 5.46% of the control group. Specifically, the positive control, as a single chemical component reference standard, had a mean inhibition rate 16.79% higher than that of the control group. However, the traditional Chinese medicine composition, through the synergistic action of multiple components, achieved a further breakthrough in inhibition rate, with a more concentrated data distribution, demonstrating the scientific and reliable nature of the formulation design.

[0183] In summary, the efficacy advantages of traditional Chinese medicine anti-allergic compositions are clearly supported by experimental data. The mean inhibition rate (41.82%) of the comparative examples (Comparative Examples 1-18) was significantly lower than that of the examples (68.57%) due to their different formulations, a difference of 26.75%. This confirms that the specific combination of traditional Chinese medicine ingredients is the core factor in enhancing hyaluronidase inhibition. Compared with the positive control (dipotassium glycyrrhizate), the traditional Chinese medicine composition, through the synergistic effect of multiple ingredients, increased the mean inhibition rate by 9.96%, exceeding the upper limit of the efficacy of a single active chemical ingredient and demonstrating the unique advantages of traditional Chinese medicine compound formulations in terms of their mechanism of action.

[0184] Test Example 3: Human skin anti-allergic and anti-itching test

[0185] 1. Principle: The mechanism of yam juice inducing itching

[0186] The sensitizing effect of fresh yam (Dioscorea opposita) juice mainly depends on the calcium oxalate raphe and protease substances it contains. Its action pathways include two types. The first is physical stimulation. The calcium oxalate raphe penetrates the stratum corneum of the skin and directly activates transient receptor potential vanilloid 1 (TRPV1) and transient receptor potential ankyrin 1 (TRPA1), triggering the transmission of itching nerve signals (similar to the mechanism of mosquito bites). The second type is chemical stimulation. Yam proteases (such as dioscorin) can break down skin surface proteins, promote the release of histamine and substance P, and amplify the inflammatory response.

[0187] The sensitizing components of yam juice were used to induce local skin irritation (itching and erythema), simulating allergic symptoms. The experimental group was treated with the target anti-allergic composition. Comparisons with the blank, model, and positive control groups evaluated the composition's inhibitory effects on itching duration, intensity, and skin inflammation, thereby verifying its efficacy in inhibiting histamine release and alleviating itching and inflammation.

[0188] 2. Experimental Materials

[0189] Chinese yam juice (allergen): Prepared by squeezing fresh Chinese yam (Dioscorea opposita) juice and filtering through a 0.22 μm pore size filter membrane. Prepared immediately before use to ensure the stability of calcium oxalate raphide activity and protease activity.

[0190] Test sample: 1.000 g of the independently developed Chinese medicine soothing and anti-allergic composition (including Examples 1 to 6 and Comparative Examples 1 to 18) was accurately weighed and dissolved in distilled water to a volume of 1000 mL.

[0191] Positive control drug: Commercially available hydrocortisone butyrate cream (produced by Hunan Dino Pharmaceutical Co., Ltd.) was used;

[0192] Blank control: distilled water.

[0193] The experimental equipment includes basic instruments such as micropipettes (accuracy ±1μL), timers, 75% alcohol cotton pads, sterile cotton swabs and thermometers and hygrometers.

[0194] The subjects must meet the following conditions: healthy volunteers aged 18-45 years, with no skin damage and history of allergies / skin diseases, not pregnant or breastfeeding, and signed informed consent; exclusion criteria include those who have used antihistamines or immunosuppressants in the past two weeks, and those who are allergic to yam or positive control drugs.

[0195] 3. Experimental Procedure

[0196] Fifteen subjects who met the inclusion criteria were recruited. On the day of the experiment, subjects entered a constant temperature and humidity laboratory (25°C ± 1°C, 50% ± 5% humidity) and sat quietly for 15 minutes to acclimate to the environment. The experimenter then cleaned the skin on the flexor side of their forearms with a 75% alcohol pad. Four symmetrical, non-overlapping test areas (2 x 2 cm, at least 2 cm apart) were then marked to serve as the blank, model, test, and positive control groups. Reagents were precisely applied using a micropipette: 50 μl of normal saline was applied to the blank group, while 50 μl of yam juice was applied to the other three groups. Immediately afterwards, the test group area was evenly covered with a traditional Chinese medicine anti-allergic composition (50 μl / cm², patted until absorbed). Hydrocortisone butyrate cream was applied in the same manner to the positive control group, while the model group received no treatment. A crossover design was employed, with all subjects receiving the traditional Chinese medicine soothing and anti-allergic compositions of Examples 1-6 and Comparative Examples 1-18 at different time points (at least one day apart), and the efficacy of each treatment was recorded.

[0197] All operations were performed by two qualified experimenters. After the intervention, a timed observation was started, and the subjects were asked to raise their hands immediately when they first felt itching. The time of the first report of itching and the intensity of the itching were recorded. After that, the experimenter asked the subjects about their itching feelings every 5 minutes and recorded the intensity of the itching. The timer was stopped when the subject's itching completely disappeared, and the duration of the itching was calculated. The visual analogue scale (VAS) was used to score the intensity of the itching, and the subjects verbally described the current itching sensation based on a score of 0-10. All data were entered into a spreadsheet in real time. After the experiment, a sterile cotton swab dipped in saline was used to remove residual reagents. All subjects were observed for 2 hours after the end of the experiment and received a telephone follow-up within 24 hours to confirm the absence of delayed allergic reactions.

[0198] 4. Evaluation Method

[0199] (1) Itch duration (minutes): The time interval from the first report of itching to the subject's confirmation that the itching sensation has completely disappeared.

[0200] (2) Itching intensity: After the allergen is applied, the time when the itching starts is counted, and the instant score is recorded every 5 minutes, and the area under the curve (AUC) is calculated.

[0201] (3) Scoring criteria: Use visual analog scale (0-10 points), record every 5 minutes.

[0202] 0 points: no itching;

[0203] 1-3 points: mild itching, not affecting concentration;

[0204] 4-7 points: moderate itching, tolerable but causing discomfort;

[0205] 8-10 points: Severe itching, unbearable and affecting normal activities.

[0206] Area under the curve (AUC) calculation:

[0207]

[0208] The total duration was the time from the first onset of itching to the complete disappearance of itching.

[0209] 5. Data Processing and Statistical Analysis

[0210] Relevant data and statistical analysis are detailed in Tables 6-10 and Figure 1 、 Figure 2 .

[0211] Table 6 Statistics of pruritus duration and pruritus intensity ( ±s, n=15)

[0212]

[0213] As shown in Table 6, the pruritus duration in the blank group was 0, and the AUC was 0, confirming the rationality of the baseline experimental design. The pruritus duration in the model group was 36.9 ± 1.66 minutes, and the AUC was 183.9115, indicating that yam juice successfully induced significant pruritus and inflammatory responses. The pruritus duration in the positive control group was 7.27 ± 0.76 minutes, and the AUC was 24.34055, demonstrating its significant anti-allergic and antipruritic effects.

[0214] The mean duration of pruritus in Example groups (1-6) was 5.34±0.12 minutes (range: 5.13-5.53 minutes), which was significantly lower than that in the positive control group. The mean AUC was 20.79±0.37 (range: 20.41-21.37), which was significantly better than that in the positive control group.

[0215] The duration of pruritus varied significantly among the comparative example groups (1-18). Some groups (e.g., comparative examples 11-18) were close to that of the positive control group, but most (e.g., comparative examples 1-10) were significantly worse than the example group (mean: 18.2±4.2 minutes). The mean AUC was 55.66±17.64, significantly higher than that of the example group.

[0220] Table 9 Verification of significance of differences between groups (Example group vs. positive control group)

[0221]

[0222] Table 10 Verification of significance of differences between groups (Example group vs. Comparative example group (combined analysis))

[0223]

[0224] The data and comparative analysis in Tables 6-10 show that the Example group exhibited significant anti-allergic and antipruritic advantages compared to the positive control group and the comparative example group. First, in terms of pruritus duration, the average pruritus duration in the Example group was 5.34±0.12 minutes, which was 26.5% shorter than the 7.27±0.76 minutes in the positive control group (p<0.01). This indicates that the Chinese herbal anti-allergic composition has a faster onset of action and can more quickly inhibit the transmission of itch signals. Second, in terms of pruritus intensity (AUC), the average AUC value in the Example group was 20.99±0.50, significantly lower than the 24.34 in the positive control group (a decrease of 13.8%, p<0.01), suggesting that it more effectively alleviates skin inflammatory responses by regulating histamine release or inhibiting inflammatory mediators (such as substance P). Further verification by independent sample t-test (α=0.05) showed that the inter-group differences of the two indicators were highly statistically significant (p<0.01), supporting that the efficacy of the Chinese medicine anti-allergic composition is better than that of the positive control drug (hydrocortisone butyrate cream).

[0225] In addition, compared with the comparative group, the advantages of the example group are more prominent. The average duration of itching in the comparative group was as long as 16.84±4.56 minutes, and the average AUC was 55.66±17.64, while the example group shortened it by 68.3% and reduced it by 62.6%, respectively. Although some formulas in the comparative group (such as comparative examples 11 to 18) showed certain therapeutic effects (such as the itching time of comparative example 18 was 9.47 minutes and the AUC was 30.71), they were still far inferior to the example group. The reason for this is that the formula of the example group has a synergistic effect by optimizing the ratio.

[0226] In summary, the experimental data combined with statistical analysis show that the Chinese herbal anti-allergic composition (example group) is not only significantly better than the hormone positive control drug in alleviating the skin itching and inflammatory response induced by yam juice, but also achieves synergistic enhancement through formula optimization, and has better therapeutic effect than the control group.
