Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine external preparations, and in particular to a male external erection aid and a preparation method and application thereof. Background Art

[0002] With the accelerated pace of modern life and increasing work and life pressures, erectile dysfunction in men has become increasingly prominent. Premature ejaculation has a serious impact on men's physical and mental health, quality of life, and family harmony. Normal sexual function relies on the coordination of multiple systems and a healthy mental and psychological state. Abnormalities in the nervous system, cardiovascular system, endocrine system, reproductive system, or mental and psychological aspects can lead to sexual dysfunction. Premature ejaculation can be caused by psychological factors, such as fear of sexual failure, emotional anxiety, masturbation, lack of sexual knowledge, and poor marital cooperation; as well as organic factors, such as spinal cord diseases, diabetes, cardiovascular disease, pelvic fractures, and genitourinary system diseases.

[0003] Western medications such as serotonin reuptake inhibitors and tricyclic antidepressants are commonly used to treat premature ejaculation, but these medications carry certain side effects. While Traditional Chinese Medicine offers a variety of herbs that can improve male sexual function, most are oral and primarily kidney-tonifying, making them inconvenient to use and neglecting the care of the male genital skin. Existing male erection enhancers and delay sprays still fail to address the slow onset and short duration of effect of topical agents. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a male external erection aid that can quickly take effect, prolong sexual intercourse time, assist erection, protect male private parts, and has few side effects, as well as its preparation method and application.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, the present invention provides a male external erection aid, comprising the following raw materials in parts by weight: 20-25 parts of traditional Chinese medicine powder, 8-15 parts of a penetration enhancer, 5-10 parts of glycerin, 20-30 parts of anhydrous ethanol, and 50-60 parts of water; wherein the traditional Chinese medicine powder is made from the following raw materials in parts by weight: 5-8 parts of epimedium, 10-15 parts of rosemary, 5-8 parts of psoralea corylifolia, 5-8 parts of kelp scutellaria baicalensis, 15-20 parts of gallnut, 5-10 parts of cnidium monnieri, and 10-15 parts of maca, and the mass ratio of psoralea corylifolia, kelp scutellaria baicalensis, and rosemary is 1:1:(1.5-2); the penetration enhancer is at least two of isosorbide dimethyl ether, nerol, and bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate.

[0007] The herb contains a large amount of flavonoids and icariin, which can dilate blood vessels and promote blood circulation in the penis. When applied externally, it can increase blood flow to the corpus cavernosum, thereby promoting erection, increasing the hardness and duration of erections, and achieving an erection-enhancing effect.

[0008] Rosemary contains 1,8-cineole and verbenone. 1,8-cineole is lipophilic, interfering with intracellular lipid synthesis and increasing permeability, meaning it also promotes transdermal absorption. It also promotes vasodilation, boosting blood circulation in the penis. Furthermore, transdermal absorption of 1,8-cineole into the bloodstream can alleviate anxiety and help reduce ejaculation latency.

[0009] Psoralea corylifolia can "treat kidney leakage, open the life gate, warm the dantian, and calm the spirit". Through its multiple pharmacological effects such as tonifying the kidney and strengthening yang, consolidating essence and reducing urine, and enhancing immunity, it can effectively support the effects of delaying ejaculation, assisting erection, and strengthening yang.

[0010] Qianjinba has the effect of "replenishing qi and blood, and assisting yang". "Lingnan Herbal Collection Record" records that it can "repel wind and dampness, treat numbness and pain in hands and feet, rheumatic pain in the waist, treat bruises and injuries, and relax muscles and tendons."

[0011] Gallnut contains a large amount of tannic acid and other ingredients. Tannic acid has an astringent effect. When applied externally, it can coagulate the local protein in the glans penis, forming a protective film, reducing the sensitivity of the glans penis, and thus prolonging the time of sexual intercourse.

[0012] Cnidium monnieri "treats swelling and pain in the genitals of women, impotence, dampness and itching in men, eliminates numbness, wards off wind and cold, breaks up hard masses, opens the chest, relieves qi, induces sweating, and promotes urination". It is warm in nature, pungent in taste, and enters the kidney meridian. It has the effect of warming the kidney and assisting yang. It improves sexual dysfunction by warming and nourishing kidney yang and enhancing kidney function. Moreover, its warming properties can improve local blood circulation and enhance erectile function.

[0013] In addition to being rich in nutrients such as protein, amino acids, minerals, and natural fiber, maca also contains active substances such as macaene and macaamide. Among them, maca polysaccharides are also the most abundant active substance in maca, which can enhance the body's physical strength and endurance, thereby achieving a delaying effect.

[0014] In summary, the present invention aims to solve the problems of slow onset of effect and low utilization rate of effective ingredients of male erectile dysfunction external preparations after external application, and adopts epimedium, rosemary, psoralea corylifolia, kelp, gallnut, cnidium monnieri and maca as effective ingredients and adds them to male erectile dysfunction external preparations, and the erectile dysfunction external preparations have good erectile dysfunction effects.

[0015] Preferably, the penetration enhancer is isosorbide dimethyl ether, nerol and bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate in a mass ratio of 1:(0.5-0.7):(1.5-2). The present invention selects isosorbide dimethyl ether, nerol and bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate as penetration enhancers. Among them, isosorbide dimethyl ether has a good balance between hydrophilicity and lipophilicity, can interact with lipids and water in the stratum corneum of the skin, and increase the permeability of the skin. This property enables it to effectively promote the transdermal absorption of traditional Chinese medicine ingredients; nerol can regulate the lipid structure of the stratum corneum of the skin, increase the permeability of the skin, and can also accelerate the structural changes of the stratum corneum of the epidermis, increase lipid fluidity, and thus promote the skin's absorption of foreign substances; bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate is a lipophilic and hydrophilic amphiphilic substance, which acts on the intercellular lipid pathway through epidermal penetration, temporarily opens the stratum corneum, and improves the penetration effect of traditional Chinese medicine ingredients into the stratum corneum. Isosorbide dimethyl ether, nerol and bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate have a synergistic effect and can significantly improve the transdermal absorption of the ingredients. The three synergistically promote the male reproductive organ's absorption of erection-enhancing and delaying Chinese medicine, shorten the onset time, and have a moisturizing or moisturizing effect on the skin.

[0016] Preferably, the male external erection aid comprises the following raw materials in parts by weight: 22 parts of traditional Chinese medicine powder, 10 parts of penetration enhancer, 8 parts of glycerin, 26 parts of anhydrous ethanol and 54 parts of water; wherein, the traditional Chinese medicine powder is made from the following raw materials in parts by weight: 6 parts of epimedium, 12 parts of rosemary, 6 parts of psoralea corylifolia, 6 parts of kelp, 18 parts of gallnut, 7 parts of cnidium monnieri and 12 parts of maca.

[0017] In a second aspect, the present invention provides a method for preparing the male external erection aid, comprising the following steps:

[0018] (1) Grinding epimedium, rosemary, psoralea corylifolia, radix schoenopraecithins, gallnut, cnidium monnieri and maca to obtain crude Chinese medicine powder, adding 5-6 times the total mass of ethanol aqueous solution of the crude Chinese medicine powder to mix, placing in a nitrogen atmosphere at 70-75° C. and reflux extraction 2-3 times, each time for 1-2 hours, combining the extracts, cooling, and filtering to remove ethanol to obtain a Chinese medicine extract;

[0019] (2) After purifying the Chinese medicine extract, drying it, and crushing it to 200-300 mesh to obtain Chinese medicine powder;

[0020] (3) The Chinese medicine powder obtained in step (2) is stirred and mixed with a penetration enhancer, glycerol, anhydrous ethanol, and water to obtain the male external erection enhancer.

[0021] Preferably, in step (1), the mass concentration of the ethanol aqueous solution is 70-80%.

[0022] Preferably, in step (2), the purification treatment is to use a macroporous adsorption resin to perform adsorption purification on the traditional Chinese medicine extract.

[0023] Preferably, in step (3), the stirring speed is 300-400 r / min and the stirring time is 10-20 min.

[0024] In a third aspect, the present invention provides the use of the male external erection aid described in the first aspect in the preparation of male products.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The erectile dysfunction agent of the present invention solves the problem of slow onset of external application. It does not add Western medicine ingredients. Instead, it selects ingredients that can be used externally or internally, namely, a combination of Epimedium, Rosemary, Psoralea corylifolia, Herba Atractylodes macrocephalae, Gallnut, Fructus Cnidii, and Maca. This can effectively prolong sexual intercourse and help erections. Among them, Rosemary can promote transdermal absorption and vasodilation, providing a better environment for the absorption and function of other ingredients; Psoralea corylifolia directly supports sexual function by tonifying the kidneys, strengthening yang, consolidating essence and reducing urine; Herba Atractylodes macrocephalae further enhances the overall effect by tonifying qi and blood, supporting yang channels, and relaxing tendons and activating collaterals. All three are indispensable in the formula.

[0027] (2) The present invention uses isosorbide dimethyl ether, nerol, and bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate as penetration enhancers, which can increase the permeability of the skin, synergistically promote the transdermal absorption of traditional Chinese medicine ingredients, shorten the onset time, and moisturize the skin.

[0065] Performance Testing

[0066] 1. Test of the number of penile erections and time to first erection in mice

[0067] Administration: Forty-five 24-month-old healthy male Wistar rats were randomly divided into nine groups of five rats each. Each group received 0.15 g of the erection enhancers described in Examples 1-6 and Comparative Examples 1-3, respectively. The rats were placed on a glass plate in a quiet room and the pubic area was evenly sprayed with the medicated spray. The rats were observed for 30 minutes, and the number of penile erections was recorded under video surveillance. One erection was defined as engorgement of the glans penis and exposure of the distal end of the penis. The results are shown in Table 1.

[0068] Table 1 Number of penile erections and time to first erection in mice

[0069]

[0070] As can be seen from Table 1, combined with the data of Examples 1-3 and 4-6, it can be seen that the penetration enhancer of Examples 1-3 is a compound of three ingredients: isosorbide dimethyl ether, nerol and bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate. The number of penile erections and the time to first erection of the mice are significantly improved compared with those of Examples 4-6. This may be because the combination of isosorbide dimethyl ether, nerol and bis-diethoxydiglycol cyclohexane 1,4-dicarboxylate can significantly improve the transdermal absorption of the ingredients. The three ingredients synergistically promote the absorption of the erection-enhancing and delaying Chinese medicine by the male reproductive organ and shorten the onset time.

[0071] Combining the data of Example 1 and Comparative Examples 1-3, it can be seen that when rosemary, psoralea corylifolia and Rhizoma Coptidis appear in the formula at the same time, the number of penile erections and the time of first erection of the mice are higher than those in Comparative Examples 1-4, indicating that the three have a synergistic effect, which makes the external use agent show a stronger effect in aiding erection, delaying ejaculation and strengthening yang.

[0072] 2. Skin irritation test

[0073] The irritation of each group of erectile dysfunction agents was evaluated in accordance with a complete skin irritation test in accordance with Item 2.3.5 of the Technical Specifications for Disinfection (2002 Edition), and the degree of skin irritation of the erectile dysfunction agents on ordinary New Zealand white rabbits was detected.

[0074] Experimental Animals: 30 standard New Zealand white rabbits, weighing 2.0-3.0 kg, provided by the Guangdong Medical Laboratory Animal Center. They were divided into 10 groups: a control group and 9 experimental groups, with 3 rabbits in each group.

[0075] The test substances of the test group include the erection aids of Examples 1-6 and Comparative Examples 1-3; and the control group uses water as the test substance.

[0076] The test animals were housed in an environment with a temperature of 18-23°C and a relative humidity of 45-65%. Twenty-four hours before the test, the hair on both sides of the dorsal spine of the animals was removed to avoid skin damage. The hair removal area was 3 cm x 3 cm. 0.5 mL of the test substance was applied to two layers of gauze (2.5 cm x 2.5 cm) and then directly applied to the skin of one test site. A closed test was performed. After 4 hours, the dressing was removed and the contact area was washed with warm water. The skin erythema and edema reactions were observed 1, 24, and 48 hours after removal of the test substance. The scores were scored according to the skin irritation response scoring criteria. The mean skin irritation score at different time points for each group was obtained and recorded in Table 2.

[0077] The highest mean score of the skin irritation reaction in each group was selected as the skin irritation index to evaluate the irritation and record it in Table 2. Among them, the skin irritation index of 0 to <0.5 represents no irritation, 0.5 to <2.0 represents mild irritation, 2.0 to <6.0 represents moderate irritation, and 6.0 to <8.0 represents strong irritation.

[0078] Table 2 Conclusions of skin irritation reactions in each group

[0079] Group Irritation Conclusion Example 1 No irritation Example 2 No irritation Example 3 No irritation Example 4 No irritation Example 5 No irritation Example 6 No irritation Comparative Example 1 No irritation Comparative Example 2 No irritation Comparative Example 3 No irritation Control No irritation

[0080] As can be seen from Table 2, the erection enhancers of Examples 1-6 and Comparative Examples 1-3 are mild and non-irritating to the skin.

[0081] In summary, the erectile dysfunction agent of the present invention can quickly take effect, prolong sexual intercourse time, and assist erection after external application by limiting the traditional Chinese medicine composition and the penetration enhancer composition, while also protecting the male private parts and being safe and non-irritating.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
