Analgesic and anti-inflammatory activity of Argyreia speciosa root
Objective: To study analgesic and anti-inflammatory activities of a
methanolic extract (ME) of Argyreia speciosa (AS) root powder.
Materials and Methods: The study was carried out using male albino mice
(20-25 gm) and male wistar rats (100-150gm). The ME was prepared using
soxhlet extraction process. The effect of ME of A. speciosa was
investigated for analgesic activity using acetic acid-induced abdominal
constriction, tail immersion method and hot plate method. The
anti-inflammatory activity of ME of AS roots was studied using
carrageenan-induced rat paw edema. Result: The ME of A. speciosa root
was used in pain and inflammation models. The analgesic activity of AS
at the dose of (30,100, and 300 mg/kg p.o) showed significant (P<
0.01) decrease in acetic acid-induced writhing, whereas ME of A.
speciosa at the dose of (100, 300 mg/kg p.o) showed significant (P<
0.01) increase in latency to tail flick in tail immersion method and
elevated mean basal reaction time in hot plate method. The ME of the A.
speciosa at doses (30, 100, and 300mg/kg) showed significant (P <
0.01) inhibition of carrageenan induced hind paw edema in rats.
Conclusion: The ME of A. speciosa showed significant analgesic and
anti-inflammatory activity in mice and rat
