Abstract

Aim of study: Stachytarpheta indica is used as herbal remedy for pains in Nigeria. Methods: To validate this claim, the analgesic, anti-inflammatory and antipyretic effects of the stem bark extract were examined in mice and rats by using acetic acid-induced writhing, tail immersion, xylene and egg albumin-induced paw oedema. While yeast and amphetamine induced pyrexia were used to study antipyretic activity in rats. LD₅₀ of the stem bark extract was carried out to determine its safety. Results: The methanol stem bark extract of Stachytarpheta indica showed significant (p<0.05) dose dependent effect in the parameters assayed. The activity of the extract was comparable to acetylsalicylic acid and morphine respectively. The acute toxicity test was greater than 5000 mg/kg. Conclusions: It may be possible that the methanol stem bark extract of Stachytarpheta indica contains biologically active substances with potential value for the treatment of painful and feverish conditions.
