✦ Synopsis

Aqueous extracts of Loeselia mexicana, Calendula officinalis, Teloxys graveolens, Oenothera roseae and

Castilleja tenuiflora were tested on the heart activity of male Wistar rats. It was found that C. officinalis, T. graveolens, L. mexicana and O. roseae inhibited the heart contractile activity rising to 100% inhibition at doses of 0.3, 0.5, 0.7 and 1.0 mg/mL respectively. However, C. tenuiflora increases the rate of the heart activity at doses from 0.1 to 0.6mg/mL.
