title: Investigation of anti-inflammatory and antinociceptive activities of Lantana trifolia.
abstract: The anti-inflammatory activity of Lantana trifolia (Verbenaceae) was determined by carrageenan, serotonin and histamine-induced rat paw edema and the analgesic activity of this plant was studied by acetic acid-induced writhings and tail flick tests in mice. Lantana trifolia extracts (at 30 mg/kg) inhibited carrageenan and histamine-induced rat paw edema. Although the extracts did not produce any effect on acetic acid-induced writhings, they all develop a significant increase on tail flick antinociceptive index (doses varying between 1 and 30 mg/kg), indicating a spinal antinociceptive effect. These results provide support for the use of Lantana trifolia in relieving inflammatory pain.
