The invention aims to provide a pure natural oceanic biological pharmaceutical composition which adopts brand-new oceanic biological active matters, is made by scientific components, and is high in antibacterial efficiency. The pharmaceutical composition mainly comprises medical
chitosan,
Eucheuma gelatinae, clam, and caloglossa. The invention further provides a preparation method of the pharmaceutical composition, the medical production formulation of the pharmaceutical composition, and application of the pharmaceutical composition in gynecologic drugs. The pharmaceutical composition extracted from natural oceanic animals and plants is nontoxic, stimulation-free, immune-
antigenicity-free and good in
histocompatibility, and is natural high-molecular compound which can be degraded and absorbed in bodies. The external preparation made by the pharmaceutical composition is convenient to use, high in antibacterial efficiency, capable of promoting epithelial
cell growing and gynecologic physiological acid-base balance, and applicable to various gynecologic
disease treating processes such as wound repair, bleeding stopping,
bacteria inhibition and
inflammation diminishing, packing after operation, and
interventional therapy.
