Abstract

The invention discloses a traditional Chinese medicine composition self-emulsifying soft capsule used for treating cold, and a preparation method thereof. According to the preparation method, fructus forsythia, Rhizoma et Radix Notopterygii, and mint are weighed according to a certain ratio, and volatile oil of the three ingredients is extracted, and is mixed with grease, an emulsifying agent, and a co-emulsifier so as to obtain a self-microemulsifying concentrated solution; and the traditional Chinese medicine composition self-emulsifying soft capsule is prepared via a conventional method. The preparation method is simple; oral absorption effect can be improved; curative effect is exact and safe; stability is high; and quality is controllable.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine, and relates to a self-emulsifying soft capsule of a traditional Chinese medicine composition for treating colds and a preparation method thereof. Background technique [0002] Viral influenza is a respiratory disease caused by multiple influenza viruses, and is an infectious disease that seriously threatens people's health, so it is also called influenza (flu). Influenza is a common acute respiratory infectious disease. The disease is highly contagious and has a sudden onset. It often causes local or even global epidemics. About 3 to 5 million people in the world are infected with influenza-like diseases every year, and the number of deaths due to influenza is about There are 250,000-500,000. The harm of influenza mainly contains: 1) because influenza virus is very easy to mutate, therefore in all parts of the world, every year there will be large or small epidemics in scope, and the ...
