Plant mosquito-repelling itch-relieving external medicament, applications and preparation method thereof

Abstract

The invention discloses a plant mosquito-repelling itch-relieving external medicament, which comprises a mixture of volatile extracts of pelargonium graveolens and sedum spectabile boreau. The provided plant mosquito-repelling itch-relieving paste comprises volatile oil extracted from pelargonium graveolens and sedum spectabile boreau; each 100 mL of volatile oil is mixed with the following components by weight: 200 to 300 grams of white vaseline, 150 to 170 parts of octadecanol, 20 to 40 parts of monoglyceride stearate, 10 to 30 grams of sodium dodecyl sulfate, 130 to 150 grams of glycerin, 3 to 5 grams of ethyl p-hydroxybenzoate, and 1800 to 2200 mL of distilled water. The inventor discovers and utilizes the characteristics of pelargonium graveolens and sedum spectabile boreau such as mosquito repelling, itch relieving, swelling eliminating, and the like, to develop a formula of a pure natural mosquito-repelling itch-relieving external medicament. According to the simple formula, external drugs with functions of repelling mosquito and relieving itch such as pastes, sprays, liniments, and the like, can be prepared.

Description

Technical field [0001] The invention involves a use of natural plant extracts for external drugs, which belongs to the field of biomedical technology \ drugs and cosmetics \ A61P: The treatment activity technology field of compounds or drug preparations. Background technique [0002] When the summer is approaching, mosquito bites have long become a major problem that plagues us. Once it is bitten, it itchy and unbearable, it can easily cause various diseases such as dengue fever and malaria, which seriously affects our work and life.

AI Technical Summary

Problems solved by technology

Although these methods have certain mosquito repellent effects, the mosquito repellent incense must be ignited to be effective in a confined space, which is easy to pollute the environment and cause people to be allergic; the mosquito repellent ring is only effective within 1cm around the ring, and toilet water and mosquitoes will not bite. Prone to skin irritation and prone to allergic reactions

[0004] At present, plant-derived repellents have low toxicity and side effects, and are not easy to cause pests to develop resistance

However, some current mosquito repelling and antipruritic medicaments either contain chemical synthesis products with various effects in their ingredients, or their components are numerous and complicated. It is difficult to complete these components, and thus the preparation cost is also very high. High, and for the extraction method of plant-derived medicinal ingredients, the operation steps are many and complicated. It is often necessary to extract the active ingredients one by one and then carry out the production and processing of the medicine. difficulty and low efficiency, and the extractant used in some extraction methods itself is irritating to the skin, and if it remains in the final product, it will also have adverse effects on the skin and affect the comfort of the antipruritic agent. Therefore, it is necessary to Minimize or possibly remove the content of these extractants by some means

The more important reason is that no plant-derived mosquito repellent with a simple formula has excellent and rapid anti-itch and swelling effects
