Marrubium vulgare L. is a medicinal plant used in folk medicine to cur
e a variety of diseases. Recently we have demonstrated that a hydroalc
oholic extract of this plant showed significant, nonspecific antispasm
odic effects on isolated smooth muscle. In this report, we have invest
igated the possible analgesic effects of the same hydroalcoholic extra
ct in different models of pain in mice. The results suggest that this
extract exhibits significant analgesic activity, antagonizing chemical
ly-induced acute pain. Such effects may be related to the presence of
steroids and terpenes, which were detected by TLC analysis.
