H Muhammad, MR Gomes-Carneiro, KS Poca, ACAX De-Oliveira, A Afzan, SA Sulaiman, Z Ismail and FJR Paumgartten (2011). Evaluation of the genotoxicity of Orthosiphon stamineus aqueous extract. Journal of Ethnopharmacology 133(2): 647-653
Orthosiphon stamineus, Benth, also known as Misai Kucing in Malaysia and Java tea in Indonesia, is traditionally used in Southeastern Asia to treat kidney dysfunctions, diabetes, gout and several other illnesses. Recent studies of Orthosiphon stamineus pharmacological profile have revealed antioxidant properties and other potentially useful biological activities thereby lending some scientific support to its use in folk medicine. So far the genotoxicity of Orthosiphon stamineus extracts has not been evaluated. In this study the genotoxic potential of Orthosiphon stamineus aqueous extract was investigated by the Salmonella/microsome mutation assay and the mouse bone marrow micronucleus test.
