Abstract

The invention discloses an external preparation for treating mosquito bites as well as a preparation method and an application. A main drug of the preparation contains a herba dendrobii extract prepared from a herba dendrobii medicinal material, wherein the herba dendrobii medicinal material is any one of herba dendrodii officinalis, dendrobium fimbriatum and noble dendrobium. The concentration ofthe herba dendrobii extract in the external preparation is 0.15%-15%. The external preparation can be any one of florida water, an ointment, a liniment and spray. The preparation method of the external preparation comprises steps as follows: the herba dendrobii extract is taken, purified water in a certain proportion is added, the mixture is mixed uniformly, and the external preparation is obtained. A preparation method of the florida water comprises steps as follows: the herba dendrobii extract is taken, florida water auxiliary materials in a certain proportion are added, the mixture is mixed uniformly, and the florida water is obtained. The external preparation can be prepared into a medicine, cosmetics and a sterilized article for treating lumps or relieving itching caused by mosquitobite.

Description

technical field [0001] The invention belongs to the field of external preparations for skin, and in particular relates to a preparation method and application of an external preparation containing dendrobium extract for rapidly eliminating mosquito bite lumps and rapidly relieving itching. Background technique [0002] Insect bite dermatitis is the most common dermatitis caused by mosquito bites. Mosquitoes stab the skin through their mouthparts, and their saliva or venom invades the skin. Since mosquito saliva or venomous gland leaching fluid contains a variety of antigenic components, these antigens can produce allergic reactions with antibodies after entering human skin and cause inflammation. In severe cases, some children may have local severe reactions such as bullae and hemorrhagic necrosis, which are common diseases in summer dermatology. [0003] Toilet water is a kind of perfume product made with toilet oil as the main fragrance and mixed with alcohol. The main e...
