Technical Field

The invention relates to the technical field of medicines and preparation thereof, in particular to a medicine for treating insect bite and a preparation method thereof.

Background

In summer and autumn, particularly in the evening, the peak period of insect activity is when people are most susceptible to the bite of insects, particularly mosquitoes. Once the skin is bitten, the skin is often itchy and intolerant, and the skin becomes red and swollen. If the itching relieving and the bag eliminating can not be timely performed and the patient continues to grasp the skin, the skin is easy to be scratched, infection and ulcer are caused, and scars can be left in severe cases.

The commercially available products for preventing and treating mosquito bites mainly comprise floral water and essential balm. The liquid products are prepared from menthol, ethanol and essence as main components, and comprise anophelifuge, Moschus and calculus bovis due to different varieties. The mosquito repellent is mainly mosquito repellent ester, the component of the mosquito repellent is pesticide, and the mosquito repellent is sprayed on the skin in a large area for a long time, so that the mosquito repellent has no side effect and is a problem which is controversial at present. When sprayed on the skin, the product can generate transient and slight cooling effect, but the main function of the product is to emphasize mosquito repelling, and the product has very limited effects on removing miliaria, relieving itching, eliminating red swelling and rash, and is difficult to effectively control pruritus symptoms.

step three: slowly adding 30-50 ml/L of purslane extract and 50-70 ml/L of selfheal extract into the container respectively, and uniformly stirring;

step four: the ethanol solution was added to the vessel to the design preparation.

Further, the extraction method of the purslane extract and the hay extract comprises the following steps:

a1: drying purslane or selfheal at 80-90 ℃ for 8-12 hours, cooling to normal temperature, and then crushing the purslane or selfheal which is dried and cooled into powder;

a2: adding the prepared purslane powder or selfheal powder into deionized water, heating and boiling for 1-2 hours, continuously boiling until a concentrated solution with the density of 1.08-1.10 is obtained, and cooling;
