Analgesic and Acute Anti-inflammatory Activities of Aqueous Root Extract of Salacia lehmbachii
Journal Title: Journal of Pharmaceutical Research International - Year 2014, Vol 4, Issue 18
Abstract
Aim: Salacia lehmbachii is used in South Eastern Nigeria folk medicine to treat abdominal pain, inflammatory disorders and malaria symptom without scientific documentation. The aim of this study was therefore, to assess possible analgesic and anti-inflammatory activities of aqueous root extract of Salacia lehmbachii (ARESL) in albino rats. Place and Duration of Study: The study was done in World Bank Step B Anti-Malaria Laboratory, Department of Pharmacology, Faculty of Basic Medical Sciences, University of Calabar, Calabar-Nigeria, between November 2013 and January 2014. Methodology: Analgesic and anti-inflammatory properties of ARESL were assessed in Wistar rats at doses of 200 and 400 mg/kg. To assess analgesic activity, acetic acid-induced writhing and formalin tests were used. To assess anti-inflammatory property, carrageenan and dextran-induced hind paw edema were used. Differences between group means were compared statistically by one-way analysis of variance (ANOVA) followed by Tukey test as post hoc. Results: In acetic acid-induced writhing test, the extract, at a dose of 400 mg/kg, showed a maximum inhibition (P=.05) of 71.66% of writhing while the standard drug Aspirin inhibited 81.05% of writhing compared to untreated control group. In formalin test, ARESL showed a maximum inhibition (P =.05) of 71.77% at a dose of 400 mg/kg while standard drug Pethidine showed 76.11%. For carrageenan-induced paw edema test, ARESL at a dose of 400 mg/kg showed maximum 85.90% inhibition (P =.05) of inflammatory activity while dextran-induced showed 87.9%. Conclusion: ARESL possesses analgesic and anti-inflammatory activities which corroborate the aqueous extract being used in folk medicine.
