[0024] Example 1: This invention provides a technical solution: a traditional Chinese medicine composition for repelling mosquitoes for pregnant women and infants, comprising the following ingredients in the indicated weight ratios: 15 parts Artemisia annua, 15 parts mosquito-repelling herb, 10 parts Paederia scandens, 10 parts Acorus tatarinowii, 10 parts Toona sinensis bark, 8 parts lemongrass, 8 parts Perilla frutescens leaf, 8 parts Gynostemma pentaphyllum, 8 parts basil, 6 parts patchouli, 6 parts Artemisia argyi, 5 parts Osmanthus fragrans, and 1500 parts water.

[0025] Working Principle: Based on the core principle of "aromatic mosquito repellent," this formula selects twelve fragrant, mild, and non-toxic Chinese herbs. The steam generated from the decoction diffuses into the air, forming an "aromatic barrier" through the volatilization of the herbs. This interferes with mosquitoes' olfactory recognition of human scents (such as lactic acid and carbon dioxide), thus repelling and avoiding mosquitoes. The formula follows the principle of "principal, assistant, adjuvant, and guide" in its formulation: Artemisia annua is the principal herb, followed by mosquito-repelling herbs such as Agrimonia pilosa, Paederia scandens, and Acorus tatarinowii. The adjuvant herbs include Toona sinensis bark, lemongrass, Perilla frutescens leaves, Gynostemma pentaphyllum, Basil, Patchouli, and Artemisia argyi, with Osmanthus fragrans serving as the guide, combining harmonizing and aromatic enhancement.

[0061] This formula primarily functions as an aromatic mosquito repellent, supplemented by purifying and calming effects. The external application of its steam diffuses into the air, purifying the atmosphere and dispelling impurities, forming a natural aromatic protective barrier. It is especially suitable for pregnant women, infants, and young children, as it is gentle and does not harm the body's vital energy.

[0062] Volatile components (such as citronellal, eucalyptol, camphor, and eugenol) affect mosquitoes' olfactory receptors through gas-phase interactions, interfering with their ability to recognize human odors. Some components have antibacterial and anti-inflammatory effects, reducing skin redness and infection after mosquito bites. After diffusion through water vapor, they form a long-lasting aromatic layer, effectively reducing mosquitoes' approach and dwell time.

[0063] This formula uses artemisia annua as the main ingredient, supplemented by various aromatic herbs, creating a harmonious scent that not only repels mosquitoes and purifies the air but also calms the mind and regulates Qi, all while remaining safe and gentle. By combining the traditional Chinese medicine theory of "aromatic mosquito repellent" with the modern mechanism of "volatile components interfering with olfactory receptors," it achieves a natural, safe, and highly effective mosquito repellent effect, especially suitable for use in the homes of pregnant women and infants.

[0064] Technical effects: Compared to chemical insecticides, it provides a natural, safe, and efficient mosquito repellent option, reducing potential health risks to pregnant women and infants, and the combination of multiple ingredients enhances the mosquito repellent effect.
