The herb yields a diterpenoid, premarrubiin, which generates marrubiin as an artefact; caffeic acid derivatives; and flavonoids—apigenin, apigenin-7- glucoside, luteolin, luteolin-7-gluco- side, quercetin-3-glucoside and -3- rhamnoglucoside. The extracts of the herb exhibit anti-inflammatory and antiserotonin activity experimentally. Marrubiin is considered to be responsible for expectorant activity. It has also shown to normalize extrasystolic arrhythmias. High doses may cause cardiac irregularities.
The oil exhibits antimicrobial properties and is reported to be vasodilatory and hypotensive.
