In the present study, mice were subjected to prolonged treatment with ethanolic extract of Salvia lachnostachys Benth leaves (SLEE), and the inflammatory and arthritic parameters were evaluated using the Complete Freund's Adjuvant (CFA) model. The genotoxicity of SLEE were also assayed using genetic toxicological tests. For the CFA model, 28 male C57BL/6 mice were distributed randomly into four groups (control, 50 mg/kg of SLEE, 100 mg/kg of SLEE and dexamethasone) for the evaluation of hyperalgesia and paw edema for 21 days after injection of CFA into the paw. To conduct the toxicogenetic assessments (comet assay and micronuclei assay), apoptosis and splenic phagocytosis were evaluated in male Swiss mice after the administration of saline (control group), cyclophosphamide (positive control group) and SLEE (10, 100 and 1000 mg/kg). SLEE significantly reduced the mechanical hyperalgesia and edema caused by CFA injection. The results of the toxicogenetic assessment revealed no toxicogenetic potential in the mice, and the evaluation of apoptosis showed an increase in apoptotic cells in the spleen after 72 h of treatment with SLEE (1000 mg/kg). SLEE exhibited anti-arthritic activity with no toxicogenetic damage. These toxicogenic results support the safety of SLEE.Graphical abstractHighlightsFirst toxicological assessment of ethanolic extract of S. lachnostachys (SLEE).The toxicological potential (genotoxic and mutagenic) of the SLEE was investigated.SLEE does not cause mutagenicity or genotoxicity.These results show that SLEE show that SLEE reduces inflammation and pain in a model of CFA-induced arthritis in mice.
