Abstract
Description
Technical Field
[0001] This invention relates to the field of traditional Chinese medicine preparations, specifically to a nasal wash containing extracts of traditional Chinese medicine and its preparation method, and more specifically to a nasal wash containing extracts of traditional Chinese medicine such as peppermint, houttuynia cordata, wolfberry, and dandelion and its preparation method. Background Technology
[0002] Rhinitis is an inflammatory condition of the nose, with main symptoms including nasal congestion, itching, runny nose, and frequent sneezing. The causes are complex, commonly including viral infections (such as during a cold), bacterial infections, contact with allergens (like pollen), or inhalation of irritating gases. Additionally, certain systemic diseases can also trigger rhinitis.
[0003] Among the many types, allergic rhinitis is the most common, usually manifesting as sudden, continuous sneezing upon exposure to pollen, dust, or similar substances. It's important to note that the "allergens" mentioned here refer to substances that some people are overly sensitive to; while most people may have no symptoms upon contact, allergy sufferers will experience a strong reaction. The severity of symptoms varies considerably among patients; some may only experience occasional runny nose, while others may suffer from chronic nasal congestion that affects their breathing.
[0004] Relevant data shows that major air pollutants such as PM2.5, ozone, nitrogen dioxide, sulfur dioxide, and vehicle exhaust can all induce allergic rhinitis. Although allergic rhinitis is not a serious disease, severe allergic rhinitis can affect sleep in 70% of cases and affect daily life and work in 94% of cases. Furthermore, allergic rhinitis may be accompanied by multiple diseases such as otitis media, sinusitis, nasal polyps, and asthma, posing a greater threat to health.
[0005] Currently, the treatment of allergic rhinitis mainly involves desensitization, hormones, and immunotherapy. These methods usually provide significant short-term relief, but the effects are difficult to maintain after discontinuation. Furthermore, hormone medications cannot be used long-term to maintain treatment effectiveness and are prone to side effects such as dry mucous membranes, nosebleeds, bad taste, and headaches.
[0006] Traditional Chinese medicine (TCM) has a history of treating allergic rhinitis for thousands of years. During the Tang Dynasty, Sun Simiao treated the disease based on the differentiation of syndromes related to lung and kidney deficiency; during the Jin and Yuan Dynasties, Liu Hejian treated it based on the theory of heat and fire; and during the Ming and Qing Dynasties, physicians treated it from the perspective of lung and spleen qi deficiency. Modern TCM has also proposed various treatment plans for allergic rhinitis from different angles, including the application of ancient prescriptions with modifications and the development of new formulas. Feng Rongchang's application of Yupingfeng Powder to treat allergic rhinitis has yielded excellent results; Cang Er Zi Powder, recorded in Volume 5 of *Ji Sheng Fang* as a treatment for nasal congestion and persistent nasal discharge, composed of Magnolia biondii, Xanthium sibiricum, Angelica dahurica, Ligusticum chuanxiong, Mentha haplocalyx, Fritillaria cirrhosa, fermented soybean, Chrysanthemum morifolium, and Glycyrrhiza uralensis, has also achieved good results in treating allergic rhinitis. Li Ming, using a randomized controlled trial, proposed a decoction made from ingredients such as Rubia cordifolia, Lithospermum erythrorhizon, Saposhnikovia divaricata, Cicadae periostracum, Pheretima aspergillum, Cynanchum paniculatum, and Prunus mume to treat allergic rhinitis, concluding that it was significantly more effective than Western medicine.
[0007] The inventors of this application have developed a traditional Chinese medicine composition wash for the effective treatment of rhinitis, especially allergic rhinitis, based on long-term clinical practice. This composition has a simple formula, easy manufacturing process, convenient administration, and few toxic side effects. It can effectively improve the rhinitis symptoms of patients and is not prone to recurrence. Summary of the Invention

[0094] Example 18: Add peppermint, houttuynia cordata, wolfberry extract and dandelion extract to water for injection, heat to 30-40℃, stir for 1-2 hours until a clear light brown solution is obtained, add sea salt; make up to volume with water for injection, continue stirring for 1-2 hours, filter (0.45μm), sterilize to obtain a nasal wash containing traditional Chinese medicine extracts.
[0095] Example 19: Efficacy test of the nasal wash of the present invention 1. Model preparation and group treatment Triamcinolone acetonide nasal spray (a corticosteroid, manufactured by Jiangxi Zhenshiming Pharmaceutical Co., Ltd.), ovalbumin (OVA), rat IgE enzyme-linked immunosorbent assay kit, and Mucin5AC antibody (Abcam, UK). Rats: 210, half male and half female, weighing 200g±30g; after one week of acclimatization feeding, the rats were divided into half male and half female.
[0096] Two hundred rats were randomly selected for sensitization: 1 mL of OVA suspension (0.9% sodium chloride, 20 mg OVA, 30 mg aluminum hydroxide) was injected intraperitoneally every other day for a total of 8 times (15 days) to induce basal sensitization. Starting on day 16, 50 μL of 10% OVA saline solution was instilled into each of the rats' anterior nostrils once daily for 10 consecutive days to induce allergic rhinitis. After successful modeling, rats were randomly assigned to the model group, positive control group, and groups described in Examples 1-18 (rhinitis wash prepared in Examples 1-18); each group consisted of 10 rats. Another 10 animals were placed in the normal control group and received intraperitoneal injection and nasal drops as before, but the medication administered was saline solution.
[0097] The normal group and the model group were given nasal washes with physiological saline, and the positive control group was given triamcinolone acetonide nasal spray. The nasal washes prepared in Examples 1-18 were used for nasal washes. Each group was given 2 ml each time, twice a day, for 3 consecutive weeks.
[0098] 2. Detection indicator: Serum IgE content detection After administration, blood was collected from the celiac artery of the rats after anesthesia, serum was separated, and enzyme-linked immunosorbent assay (ELISA) was performed according to the kit instructions.
[0099] 3. Statistical Analysis Methods Data were processed using SPSS software and analyzed using one-way ANOVA. Data are expressed as mean ± standard deviation. P < 0.05 was considered statistically significant.

[0102] 2. Model preparation was the same as in Example 19. Rats were divided into 13 groups, randomly assigned as the model group, Examples 1-4, 9-12, 14-15, and 18 (the prepared nasal wash was aged for 3 months); each group contained 10 rats. Another 10 were selected as the normal group and administered intraperitoneal injection and nasal irrigation as before, but the medication given was physiological saline.
[0103] The normal group and the model group were given nasal washes with physiological saline, and the nasal washes prepared by the example group were given 2 ml each time, twice a day, for 3 consecutive weeks.
[0104] 3. The detection indicators and statistical analysis methods are the same as in Example 19.
