In vivo analgesic, antipyretic and anti-inflammatory potential of ethanol extract from Plukenetia volubilis Linneo leaves in mice
Main Article Content
Abstract
Plukenetia volubilis L. is traditionally utilized for managing joint pain, muscle discomfort, wound healing, and infection prevention. Despite this extensive use, the specific analgesic, anti-inflammatory, and antipyretic activities of the ethanol extract from P. volubilis leaves (PVEE) remain underexplored, warranting further investigation. The study results revealed that PVEE possesses notable analgesic effects, as evidenced by a significant increase in tail-flick latency (p < 0.05), inhibition of pain responses (p < 0.05), a reduction in writhing frequency (p < 0.05), and a decrease in paw swelling (p < 0.05) in inflammatory models. Additionally, PVEE demonstrated antipyretic properties by significantly reducing rectal temperature (p < 0.05) in a yeast-induced fever model. Furthermore, the extract exhibited strong anti-inflammatory effects, as it significantly reduced paw edema (p < 0.05) and inhibited the release of pro-inflammatory cytokines, such as IL-6, IL-1β, and TNF-α (p < 0.05). These results highlight the potential of PVEE as a promising therapeutic option for pain relief, fever reduction, and inflammation management.
