The bulb of an onion-like plant, of which the syrup is most used. It is an excellent cough-medicine (expectorant): rather less loosening than ipecac, and therefore suited to a later stage in a bronchial attack. Dose, from a half tea-spoonful to a teaspoonful. This syrup should be in every medicine-chest.

In pill, squill is often given as a diuretic (increasing the flow of urine). Dose for this use, one or two grains, three times daily.
