ABSTRACT
Schinus terebinthifolius Raddi is a medicinal plant known in Brazil as "aroeira da praia", which has been used in popular medicine as antipyretic, analgesic, depurative and in the treatment of diseases of the urogenital system. On the other hand, the scientific literature has reported that this plant has antimicrobial, anti-inflammatory and antiulcerogenic activity. This review addresses the main biological properties and toxicological effects of "aroeira da praia", in addition to a systematic approach of the compounds that were already found in this species, the great majority of which is present in the essential oils.

OBJECTIVES: This study evaluated subcutaneous tissue response to Aroeira (Myracrodruon urundeuva) extract employing edemogenic and histological analyses. MATERIAL AND METHODS: Test groups consisted of aqueous and ethanolic Aroeira extracts and saline (control). For edema quantification, 18 rats received an intravenous injection of Evan's Blue. After 30 min, the extracts and saline were injected on the dorsum of the rats, which were then sacrificed after 3 and 6 h. Readings were performed in a spectrophotometer. For subcutaneous implantation, 30 rats received a polyethylene tube containing the extracts on their dorsum and then they were killed after 7 and 28 days. The samples were processed for histological analysis and evaluated with a light microscope. The inflammatory infiltrate was quantified. RESULTS: There were no statistically significant differences between aqueous extract and saline groups in relation to edema quantification in the different periods (p>0.05). Ethanolic solution resulted in more edema independently of the experimental period (p<0.05). Histological analysis showed similar results on the 7-day period for the 3 groups. There was a notable reduction on inflammatory cell number for saline and aqueous extract groups at 28 days. CONCLUSION: The aqueous extract showed biocompatible properties similar to those of saline.

The antibacterial potential of leaf's essential oil (EO) from Brazilian pepper tree (Schinus terebinthifolius Raddi) against staphylococcal isolates from dogs with otitis externa was evaluated. The minimum inhibitory concentration of EO ranged from 78.1 to 1,250 fg/mL. The oil was analyzed by GC and GC/MS and cytotoxicity tests were carried out with laboratory animals.
