Antiinflammatory activity of a Ghanaian antiarthritic herbal preparation: II.

A boiling water extract from a mixture of Alstonia boonei and Rauvolfia vomitoria root barks and Elaeis guineensis nuts without pericarp was tested for its antiinflammatory activity by measuring over a period of 17 days the changes in rat ankle diameter caused by subplantar injection of complete Freund's adjuvant. The extract fed in drinking water ad libitum reduced ipsilateral ankle adjuvant swelling by an average of 16% for the period of +4 to +17 days and improved weight gain.
