Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Papaya (Carica papaya) has been traditionally used in various cultures for its purported wound-healing properties, including the management of external bleeding. Historical and ethnobotanical sources document the use of papaya latex, leaves, or pulp as topical agents to promote hemostasis and wound closure. Traditional healers in tropical regions have long applied mashed papaya or its latex to cuts, ulcers, and other skin injuries, attributing its effectiveness to its proteolytic enzymes (such as papain), which are believed to aid in cleansing wounds and promoting tissue regeneration.

However, while these practices are well-documented in folk medicine, scientific validation is limited. Some laboratory studies suggest that papaya extracts possess antimicrobial, anti-inflammatory, and possibly mild hemostatic properties, but well-designed clinical trials in humans are lacking. The proteolytic enzymes in papaya may help debride necrotic tissue, which can support wound healing, but direct evidence for stopping active bleeding is minimal. Most available evidence is anecdotal or from small case series.

Thus, the use of papaya for external bleeding is primarily justified by tradition rather than robust scientific evidence. Its rating is 2, indicating weak evidence based largely on historical and anecdotal use, with some preliminary scientific rationale but lacking strong clinical confirmation.
