Henna (Lawsonia inermis) has a long history of use in traditional medicine, particularly in regions of South Asia, the Middle East, and North Africa. Historically, powdered henna leaves have been applied to minor wounds, abrasions, and burns to promote healing and prevent infection. This traditional use is based on henna's perceived cooling, soothing, and antimicrobial properties, which have been recognized in Unani, Ayurvedic, and folk medicine systems. The application of henna paste is reported to form a protective layer over abrasions, potentially shielding the wound from environmental contaminants.

Some laboratory studies have shown that henna extracts possess antibacterial and antifungal activity, which could theoretically support its traditional use for minor skin injuries. However, clinical evidence demonstrating effectiveness specifically for treating abrasions is lacking or very limited. Most of the support for henna in wound care is historical and anecdotal rather than rigorously tested in controlled clinical trials. Therefore, while there is a tradition of using henna for abrasions, scientific validation remains preliminary and incomplete.

In summary, the use of henna to support or treat abrasions is primarily justified by cultural and traditional practices, with modest laboratory evidence but limited clinical validation.
