Research suggests that papain, a proteolytic enzyme derived from papaya, shows promise as a wound care agent, particularly for enzymatic debridement of necrotic tissue and as a component of advanced wound dressings. The available evidence includes systematic reviews, animal studies, and laboratory experiments examining papain in various forms—gels, hydrogels, nanoparticles, and composite dressings—with findings generally indicating that papain can facilitate removal of dead tissue, reduce inflammation, support collagen organization, and potentially limit hypertrophic scarring. Studies indicate that papain may work comparably to or faster than other enzymatic agents like collagenase in clearing necrotic tissue, and newer delivery systems combining papain with other bioactive compounds have shown encouraging results in preclinical models of chronic and diabetic wounds. However, the evidence base is limited by a predominance of animal and in vitro studies rather than rigorous randomized controlled trials, some reports of side effects such as burning and pain, regulatory concerns that led to its removal from the U.S. market, and a general lack of head-to-head comparisons with other treatments, meaning the overall picture remains mixed and further high-quality clinical research is needed before firm conclusions can be drawn.
