Propobase bioadhesive gel is a preparation containing propolis extract in a gel medium formulated to allow prolonged (up to 10 hours) and controlled release of the active substance. The thermoreversible properties of the gel allow its application in the form of drops (when stored in the refrigerator) and the formation of the gel "in situ" at body temperature. This is especially advantageous for painful aftershocks and mucosal injuries. Propolis and surfactants originating from bioadhesive gel accelerate the epithelization of the skin and heal smaller wounds.
