Análise da ação cicatrizante do óleo da Schinus terebinthifolius Raddi (aroeira-vermelha) na regeneração da tendinite induzida em ratos

Abstract

INTRODUCTION: Tendinopathy is a term used to describe injuries that affect tendons, with the primary characteristic being the presence of inflammatory processes and tissue degeneration, associated with mechanical overload or repetitive movements. It is directly related to intrinsic and extrinsic factors, such as age, sex, and vascular supply. The red aroeira belongs to the Anacardiaceae family, a species native to Brazil, and is popularly known in traditional medicine for its astringent, anti-diarrheal, and anti-inflammatory properties. OBJECTIVE: To evaluate the anti-inflammatory and healing effects of the cream-gel enriched with the essential oil of Schinus terebinthifolius Raddi (Red Aroeira) leaves. METHODOLOGY: The essential oil was incorporated into the cream in the proportion of 50 g of cream to 500 mg of oil. The lesions were induced enzymatically with collagenase. Applications followed the 7, 14, and 21-day protocol. RESULTS: The analysis of paw edema and histology showed that all animal groups treated with Red Aroeira Cream had better recovery of their lesions compared to other groups. CONCLUSION: The findings indicate that the use of Red Aroeira Cream has beneficial effects in the treatment of experimental tendon injuries in rats. However, it is important to highlight that these are purely descriptive findings, and quantitative methods are necessary for a more accurate evaluation.
