Liquorice, Licorice, Spanish liquorice, E. Spaniches Siisstiolz, G. 

 Reglisse, Bois de re"glisse, Bois douce, Racine douce, Fr. 



The roots and rhizomes (underground stems) of Glycyrrhiza 

 glabra typica R et H., and G. glabra glandulifera R et H., Leguminosae. 



Bright, pale yellow. 



Nearly odorless, somewhat heavy. 



Very sweet, slightly pungent and somewhat mucilaginous. 



Parenchyma cells medium sized, typical, rather thin-walled and 

 loosely united; filled with simple, small oval starch granules. Typical 

 bast plentiful, accompanied by numerous crystal bearing fibers. 

 Numerous parenchyma cells with prismatic crystals. Porous and 

 reticulate ducts. The unpeeled licorice shows cork tissue. 



The ash of the peeled roots should not exceed 6 per cent., and 

 that of the unpeeled roots should not exceed 8 per cent. 



There is no recognizable histological difference between the Spanish 

 and Russian varieties. Cork tissue is of course wanting in the peeled 

 article. Trimmings and milling refuse may be used as adulterants.
