Abstract

The invention is to provide a hydrogen sulfide sustained releasing dressing and a manufacturing method thereof. The hydrogen sulfide sustained releasing dressing includes a hydrocolloid, a surfactant and sodium hydro sulfide. The manufacturing method includes (a) heating and stirring a hydrocolloid material; (b) adding a surfactant and sodium hydrosulfide into the hydrocolloid material; and (c) injecting the hydrocolloid material containing the surfactant and the sodium hydrosulfide into a mold for thermoforming a hydrogen sulfide sustained releasing dressing.
