Abstract

The invention discloses an external preparation for skin eczema. The external preparation is prepared from 0.1%-0.5% of menthyl p-methoxy cinnamic acid, 0.5%-5% of carboxyamino chitosan, 50%-80% of traditional Chinese medicine extract and the balance purified water. The preparation method of the preparation comprises the following steps that 1, the traditional Chinese medicine extract is prepared;2, a carboxyamino chitosan solution is prepared; 3, the menthyl p-methoxy cinnamic acid is prepared; 4, a finished product is obtained. The external preparation prepared through the method for the skin eczema has the good percutaneous absorption effect, the traditional Chinese medicine ingredients and the menthyl p-methoxy cinnamic acid and the carboxyamino chitosan have the good synergy effect,the traditional Chinese medicine active ingredients have the good percutaneous absorption effect, various pruritus and infections caused by the skin eczema can be rapidly relieved, and meanwhile the defects that traditional Chinese medicine water extract contaminates clothes, the curative effect is poor, and precipitation is separated out are avoided, preservative does not need to be added for thepreparation, it is guaranteed that liquid medicine containing the traditional Chinese medicine ingredients does not mildew, and the phenomena that due to a commercial aseptic operation, the characteristic curative effect changes, and the cost is lower are avoided.

Description

technical field [0001] The invention relates to the field of medical medicine and preparation technology, in particular to an external preparation for skin eczema and a preparation method thereof. Background technique [0002] Eczema is a skin inflammatory reaction with severe itching caused by various internal and external factors. Divided into acute, subacute and chronic three stages. In the acute phase, it tends to exudate, while in the chronic phase, it is infiltrating and hypertrophic. Some patients directly show chronic eczema. The skin lesions are characterized by pleomorphism, symmetry, itching, and recurrent attacks. [0003] The pathogenesis of skin eczema is very complicated, and it can be simply divided into internal factors and external factors. It is difficult to distinguish between the primary and secondary factors, and they are usually related to each other and act synergistically. External factors such as chemical agents, cosmetics, animal toxins, fish a...
