Abstract

This invention is related to chitosan filmogenic liquid for wound healing. It particularly relates to small to chronic wounds healing using filmogenic liquid applied on site which is made of pharmaceutical grade chitosan. The proposed bioactive wound healing chitosan filmogenic liquid heals even the traumatic wounds by promoting natural cell growth factors and resulting into pleasing wound healing. The filmogenic liquid chitosan and a method of obtaining the same are also disclosed. A method of obtaining pharmaceutical grade chitosan from crude chitosan is also proposed.
