Effects of 1.8-cineole (eucalyptol) on the spontaneous contractile activity of smooth muscles fibre
Eucalyptus oil is frequently used in phytotherapy. The objective of the present paper was to investigate to what extent 1.8-cineole influences the activity of smooth muscle fibres. The effects of 1.8-cineole on the spontaneous contractile activity were investigated in in vitro experiments with circular smooth muscle fibres of guinea pig stomach. 1.8-cineole was found to have agonistic effects on the a1 and a2 adrenergic...
