Biological and phytochemical evaluation of plants. XIV. Antiinflammatory evaluation of 163 species of plants.

One hundred and seventy-seven plant extracts, representing 163 species of plants and/or fungi, were evaluated in rats to determine their antiinflammatory activity using the carrageenin-induced pedal edema assay. Of the 163 species of plants and/or fungi tested, 17 exhibited between 30--39 per cent inhibition of inflammation, 21 between 40-49 per cent, 15 between 50--59 per cent, four between 60--69 per cent, and two gave greater than 70 per cent inhibition of carrageenin-induced pedal edema.
