Mulleins (Verbascum Thapsus) are biennial or perennial plants and rarely annuals or sub-shrubs. The leaves and flowers are the parts used medicinally. Preparations of the plant have been ingested, applied topically, and smoked. It has markedly demulcent, emollient and astringent properties, which render it useful in pectoral complaints and bleeding of the lungs and bowels. The whole plant seems to possess slightly sedative and narcotic properties.
