The aqueous leaves extract of Ocimum Gratissimum   was investigated for anti-nociceptive and anti-inflammatory effects in mice and rats. The models used to study the effect on nociception are the acetic acid-induced abdominal constriction test, hot- plate method in mice. The anti-inflammatory effect was investigated employing the formalin-induced hind-paw oedema in rats. The extract caused a significant (p<0.05), dose-dependent inhibition of acetic acid-induced writhing and hot-plate method .The extract also exhibited anti-inflammatory effect which was significant (P<0.001) at all the three doses. .The intraperitoneal LD50 value of the extract was 1264.9mg/kg body weight in mice. Preliminary phytochemical screening revealed the presence of alkaloids, saponins, tannins and flavonoids. The results suggest the extract contained pharmacologically active principles, and supports the local application of the plant in painful and inflammatory conditions.
