The present invention relates to a method for manufacturing a gypsum board by the natural plant fiber of the natural fibers as a main material. What should be the interior materials it gives life to create a comfortable space in the room completely harmless to the human body and be made of materials that help healthy living. As a main ingredient of natural plant fibers, natural fibers of hemp fiber in the gypsum board production methods and the production of a mixture of quicklime, gypsum, vermiculite. Worm strong tensile and strong alkali of quicklime in the village fibers, insects, larvae microorganisms is an appropriate amount of gypsum containing fireproof, sound absorption, insulation, fillers functionality was added to the uniqueness non-breeding using heat-expanded vermiculite at high temperature mixed to provide a production method and production of natural fiber gypsum board made with natural materials and also break advantage at all harmless to the human body that are produced by light and thin.
