The use of Brazilian peppertree (Schinus terebinthifolia) for treating abrasions is primarily rooted in traditional medicine. In several regions of South America, especially in Brazil, indigenous and local communities have historically used various parts of the plant—such as the leaves, bark, and resin—as topical applications for wounds, abrasions, and skin infections. Ethnobotanical surveys and records document these practices, attributing the plant’s efficacy to its antimicrobial and anti-inflammatory properties. Preparations are typically applied directly to the affected skin to prevent infection and promote healing.

Scientific studies have provided some support for the antimicrobial action of extracts from S. terebinthifolia, including activity against bacteria commonly associated with skin infections. For example, in vitro research has shown that extracts can inhibit the growth of Staphylococcus aureus and other pathogens. However, direct clinical evidence supporting the efficacy of Brazilian peppertree specifically for treating abrasions in humans is limited. Most available data are preclinical or based on traditional usage rather than controlled clinical trials.

In summary, while there is a notable foundation in traditional medicine and some preliminary scientific evidence for antimicrobial activity, robust clinical validation for the use of Brazilian peppertree in treating abrasions is lacking.
