Abstract

The invention discloses a preparation method for compound mosquito repelling and itching relieving floral water. The method comprises the following steps: preparing, by weight, 10 to 35 parts of orange blossom, 10 to 25 parts of tarragon, 10 tor 45 parts of sweet wormwood leaf, 10 to 35 parts of lavender, 10 to 35 parts of lemongrass, 10 to 25 parts of mint, 10 to 35 parts of yellow willow herb and 5 to 25 parts of cicada slough; crushing orange flower, tarragon, sweet wormwood leaf, lavender, lemongrass and mint together, extracting plant essential oil from an obtained mixture by using supercritical carbon dioxide, crushing yellow willow herb and cicada slough together, carrying out extraction on an obtained mixture of yellow willow herb and cicada slough by using the percolation method,standing an obtained extract for more than 48 hours, taking a supernatant of the extract, and evenly mixing the supernatant with the plant essential oil obtained in supercritical carbon dioxide extraction so as to prepare a solution preparation of the floral water. The solution preparation has the advantages of strong mosquito poisoning and repelling capability, good effects in diminishing swelling and relieving itching, safety, no toxic and side effects, good stability and small possibility in generation of drug resistance.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine preparations, and in particular relates to a preparation method of compound mosquito repellent and antipruritic toilet water. Background technique [0002] Mosquitoes feed on human blood and can transmit diseases such as malaria, filariasis, Japanese encephalitis and dengue fever, causing serious public health problems. For a long time, people have been seeking various methods to control mosquitoes. Some chemical insecticides that have been used have good mosquito control effects and long-lasting effects, such as DEET (N,N-diethyl-m-methylbenzamide), It has played a pivotal role in the control of mosquito-borne diseases in many areas, and also plays an irreplaceable role in people's daily life. [0003] With the extensive use of insecticides in the past 50 years, the resistance of mosquitoes has become stronger and stronger, resulting in an increase in the number of mosquitoes, whi...
