Description

technical field [0001] The invention relates to the field of mosquito preparations, in particular to a neem repelling mosquito composition and its preparation method and application. Background technique [0002] With the arrival of summer, mosquitoes start to move again. After biting, not only bring various discomforts such as itchy skin, redness and swelling, but also easily infect diseases, affecting people's normal life. After the mosquito bites, its saliva or venom invades the skin, because the mosquito saliva or the leachate of the venom gland contains a variety of antigen components, these antigens can produce allergic reactions with antibodies after entering the human skin and cause inflammation. In severe cases, individual patients may locally produce severe reactions such as bullae and hemorrhagic necrosis, which are common diseases in summer dermatology. Hainan is located in a tropical rainforest area, with an average annual temperature above 20°C. Mosquitoes liv...
