Abstract
The effect of the volatile oil of Teucrium polium was investigated in vitro using isolated segments of rabbit intestine. The volatile oil was found to inhibit the spontaneous movements of the intestine and the contractions of the intestine induced by depolarization with high potassium (K+) solution. Also, the volatile oil was found to inhibit 45Ca influx in the intestine in a dose dependent manner. Our results suggest that the volatile oil inhibits Ca2+ influx through the potential dependent Ca2+ channels.
