Antispasmodic and relaxant effects of the hidroalcoholic extract of Pimpinella anisum (Apiaceae) on rat anococcygeus smooth muscle

Because Pimpinella anisum is highly used in the folk medicine, a study of its physiological properties was deemed necessary and informative. At present, the mechanisms involved
in the relaxant action induced by the extract of Pimpinella anisum are poorly understood. This work aimed to investigate the possible mechanism(s) underlying the relaxant action of
the hidroalcoholic extract of Pimpinella anisum on rat anococcygeus smooth muscle.
