Action and Uses. - Linseed tea is a most useful demulcent in coughs depending in whole or in part on irritation of the pharynx and upper part of the respiratory passages. It may be kept warm all night in a baby's food-warmer, and a sip taken whenever the patient awakes. This often prevents troublesome paroxysms of coughing, and enables the patient to obtain a fair night's rest. Internally it is used as a demulcent drink in enteritis, diarrhoea, dysentery, catarrh, and irritation of the urinary organs, also in phosphorus-poisoning.
