Orthosiphon aristatus (Blume) Miq., which can be used as a food ingredient, is grown throughout
Southeast Asia and Australia. O. aristatus is frequently used for the treatment of renal inflammation,
kidney stones and dysuria. The focus of the current work was to study the antioxidant and
anti-inflammatory effects of methanol, ethanol and water extracts from O. aristatus (abbreviated as
MEOA, EEOA and WEOA, respectively).
