In the subacute toxicity study, biochemical evaluation is important because kidney and liver toxicity have been reported following the use of phytotherapeutic products
(Hilaly et al., 2004; Isnard et al., 2004; Saad et al., 2006).
In the present study, it was not observed significant alterations of the levels of AST/ALT, urea and creatinine caused by EsEO administration.
This result indicates that kidney and hepatic functions were preserved.
