Description

Liquorice or Licorice is the root of a plant named Glycyrrhiza glabra known for its sweet flavor extract. New crop 
 

The Liquorice of medicine and commerce is derived from the sweet root of various species of Glycyrrhiza, a genus which contains about fourteen species, natives of warmer temperate countries in both the New and Old Worlds, ten of them having roots more or less sweet, but most of them not sufficiently so to be of use.

Hundreds of tons of Liquorice for commercial and medicinal purposes are imported annually from Spain, Russia, Germany, France and the East.

Medicinal Action and Uses**-The action of Liquorice is demulcent, moderately pectoral and emollient.

It is a popular and well-known remedy for coughs, consumption and chest complaints generally, notably bronchitis, and is an ingredient in almost all popular cough medicines on account of its valuable soothing properties.

The Extract enters into the composition of cough lozenges and pastilles, with sedatives and expectorants. It is largely used in conjunction with infusion of linseed in the treatment of irritable cough, sore throat and laryngitis, and an infusion made by boiling 1 OZ. of the bruised root deprived of its bark, with 1 pint of water for a few minutes, may be employed in the treatment of sore throat and in catarrhal conditions of the urinary intestinal tracts.

Fluid Extract of Liquorice is employed almost exclusively as a vehicle for disguising the taste of nauseous medicines, having a remarkable power of converting the flavour of acrid or bitter drugs, such as Mezereon, Quinine or Cascara.

The powdered root is useful in pill-making on account of its absorbent qualities, being used to impart stiffness to pill masses and to prevent the adhesion of pills.

As a remedial agent, powdered Liquorice root has been almost entirely replaced by the extract, though it is used in the well-known Compound Liquorice Powder, the mild laxative in which Senna and Fennel are the other ingredients. It is added mainly on account of its sweetness and emollient qualities, the action of the powder being mainly due to the Senna contain (Source Wikipedia)
