Balsam, particularly forms such as Peru balsam (Myroxylon balsamum), has a long-standing history of traditional use in treating minor skin wounds, including abrasions. The resinous exudate has been used in folk medicine for its purported antiseptic and healing properties. Historically, it was applied topically to minor injuries to promote healing and protect against infection due to its aromatic, sticky nature, which can form a protective barrier over wounds.

Some early pharmacopoeias and herbal texts mention the use of balsams for skin ailments and wound healing. However, modern scientific research validating these effects is limited. While in vitro studies suggest that some compounds found in balsam may exhibit mild antimicrobial or anti-inflammatory activity, robust clinical trials verifying its efficacy for treating abrasions in humans are lacking. Moreover, balsam can be a contact allergen and may cause dermatitis in sensitive individuals.

In summary, the use of balsam for abrasions is primarily justified by traditional practices rather than strong scientific evidence. It may provide some benefit as a protective dressing and could have minor antimicrobial effects, but its use should be approached with caution due to the risk of allergic reactions. Modern wound care relies on better-studied and safer alternatives.
