Indian Mustard (Brassica juncea) has been used traditionally in various cultures, particularly in Ayurveda and traditional Indian folk medicine, to promote the healing of minor skin injuries such as abrasions. The seeds of Indian Mustard are often processed into mustard oil, which is applied externally. Traditional uses suggest that mustard oil acts as a natural antiseptic and may help in cleansing wounds and accelerating healing, possibly due to its warming properties and the presence of compounds like allyl isothiocyanate, which can have mild antimicrobial effects.

However, there is a lack of robust scientific evidence or controlled clinical trials specifically investigating Indian Mustard or mustard oil for the treatment of abrasions in humans. Most of the support for its use comes from historical texts and ethnobotanical reports rather than modern pharmacological validation. While some in vitro studies have indicated antimicrobial properties of mustard oil, these findings have not been directly linked to wound healing or the management of abrasions in clinical settings. Additionally, application of mustard oil on broken skin may cause irritation in some individuals.

In summary, the use of Indian Mustard for abrasions is justified by tradition rather than scientific validation, and the overall level of evidence is low.
