Botanical name:
Glycyrrhiza spp.
There are around 20 species of Glycyrrhiza, a number of species have been used as a source of 'Licorice':
  1. G. glabra; regular 'Licorice', native to Eurasia
  2. G. echinata (syn. G. inermis, G. macedonica), German, Roman, Hungarian, East European or Chinese Licorice.
  3. G. glabra var. glanulifera, Russian Licorice
TCM uses G. uralensis, G. inflata ('Chinese Licorice'). G. yunnanensis ('Yunnan Licorice') as well as G. glabra and others.
There is sufficient crossover of the above-named species to say they are synonymous in use, although some will be stronger than others.
