Fiber membrane as well as preparation method and application thereof

The invention belongs to medical materials, and particularly relates to a fiber membrane and a preparation method and application thereof. The fiber membrane is prepared from fibers of a shell-core structure, a shell layer contains degradable materials, and a core layer contains coriaria sinica extract and chinaroot greenbrier extract. The main active component of coriaria sinica is a coriaria sinica lactone compound, and the coriaria sinica has antibacterial and anti-inflammatory effects; the chinaroot greenbrier has the effects of promoting diuresis, removing turbidity, dispelling wind, eliminating arthralgia, detoxifying and dispersing blood stasis, and has an obvious anti-inflammatory effect. Through coaxial electrostatic spinning, the core layer contains the coriaria sinica extract and the chinaroot greenbrier extract at the same time, and the shell layer is made of a degradable material, so that drugs can be effectively prevented from being damaged or denatured, wound healing is promoted, and meanwhile,
