Ranunculus sceleratus is a widespread species with unique toxicological and pharmacological activities. The present study seeks to assess this species' ability, both in vitro and in vivo, to modulate processes involved in inflammations. To this end, different extracts from the aerial parts of the plant were tested in several models of acute inflammation induced by tetradecanoylphorbol acetate (TPA), arachidonic acid (AA), and carrageenan, as well as in two models of delayed hypersensitivity induced by oxazolone and dinitrofluorobencene (DNFB). The extracts were also assayed in models of eicosanoid and elastase release by intact cells. When tested in vivo, all of the extracts showed anti-inflammatory or neutral effects. In vitro, non-polar extracts of this species were able to inhibit eicosanoid production, whereas polar extracts enhanced the synthesis of 5(S)-HETE, LTB(4) and 12(S)-HHTrE. The hypothesis of a "counter-irritant" mechanism of action has thus been proposed and is also discussed herein.
