Abstract: RACIONAL: A gastrorrafia isolada ou associada ao uso de adesivos biológicos constituiu ao longo da história da cirurgia a forma usual de promover a cicatriza o nas les es gástricas e o uso de fitoterápicos tem sido cada vez mais empregado. OBJETIVO: Avaliar a cicatriza o de ferida provocada no est mago de ratos com uso do extrato hidroalcoólico de Schinus terebinthifolius Raddi. MéTODOS: Foram utilizados 60 ratos, adultos, machos, distribuídos em dois grupos: grupo aroeira e grupo controle, os quais foram subdivididos em três subgrupos de cinco animais conforme o momento das mortes dos animais (7, 14 e 21 dias). Todos os animais foram submetidos ao mesmo procedimento cirúrgico (les o e rafia do est mago) diferindo apenas que os animais do grupo aroeira receberam dose diária de 100 mg/kg do extrato hidroalcoólico via gavagem enquanto o grupo controle recebeu solu o salina isot nica. Os parametros avaliados foram: altera es macroscópicas e microscópicas, teste de resistência à insufla o de ar atmosférico e teste pela for a de tra o. RESULTADOS: Todos os animais demonstraram boa cicatriza o da parede abdominal e das gastrorrafias, sem infec o e deiscência. Ambos os grupos apresentaram aderências à superfície das gastrorrafias com órg os vizinhos. O teste de resistência por insufla o de ar atmosférico e for a de tra o mostraram maiores médias de press o no 7o dia e de for a de ruptura nos períodos estudados para o grupo aroeira. A intensidade da inflama o cr nica revelou diferen a estatisticamente significante nas variáveis prolifera o fobrobrástica e colageniza o. CONCLUS O: O uso do extrato hidroalcoólico de Schinus terebinthifolius Raddi acelerou a cicatriza o do est mago de ratos. BACKGROUND: Gastrorraphy, isolated or associated with the use of biological adhesives, was throughout the history of surgery the usual way to promote healing in gastric lesions and the use of herbal medicine has been increasingly more employed. AIM: To evaluate the wound healing in the stomach of rats with the use of the hydroalcoholic extract of Schinus terebinthifolius Raddi (aroeira). METHODS: Sixty rats, adult males, were divided into two groups: aroeira group and control group. Each one was subdivided into four subgroups of 15 animals (test groups). Each subdivided subgroup was also subdivided into three subgroups of five rats (deaths periods of 7, 14 and 21 days). All animals underwent the same surgical procedure (injury and stomach suture); animals in the aroeira group received daily dose of 100 mg/kg of hydroalcoholic extract via gavage while the control
