Description

technical field [0001] The invention relates to the technical field of medicinal mosquito repellent, in particular to a method for preparing mosquito repellent liquid based on eight traditional Chinese medicines. Background technique [0002] Mosquitoes stab the skin through their mouthparts, and their saliva or venom invades the skin. Since the saliva or venomous gland leachate of mosquitoes contains a variety of antigenic components, these antigens can produce allergic reactions with antibodies after entering human skin, causing inflammation. In severe cases, severe reactions such as bullae and hemorrhagic necrosis will occur locally, which is a common disease in summer dermatology. At the same time, female mosquitoes are intermediate hosts for other pathogens such as dengue fever, malaria, yellow fever, filariasis, and Japanese encephalitis. The technology of killing or repelling mosquitoes is widely used in daily life. [0003] At present, common mosquito coils, mosqui...
