Soapwort is a typical saponin drug, which in low doses promotes expectoration. Via irritation of nerve endings in the gastric mucosa, there is a reflex stimulation of water secretion in the bronchi and thus increased expectoration.
The viscosity of the bronchial mucus is also reduced by saponins and the activity of the ciliated epithelium, the small hairs that sit on the surface cells of the bronchi and transport the mucus upwards, is increased. All of this also facilitates expectoration.
