Therapy—The agreeable taste of liquorice in any form covers to a practical extent the taste of very many disagreeable remedies. Acrid and bitter tastes are well disguised by it. A syrup made by adding two parts of the fluid extract to fourteen parts of simple syrup, will disguise the bitter or otherwise unpleasant taste of a large proportion of the fluid extracts. The taste of quinine can be concealed by it to a considerable extent.

Its demulcent properties render it useful in inflammation, or irritation of the mucous membranes of the lungs and bronchi. In combination with ipecac, lobelia, squill, sanguinaria, or ammonium chloride, an excellent expectorant mixture or cough syrup may be extemporized, as this agent modifies any acrid or irritating influence the other agents may exhibit.

The virtue of the Compound Liquorice Powder of the dispensatory does not depend upon the properties of the liquorice, only as it imparts to the whole a pleasant taste.
