Editing Galangal (section)

==Differentiation==
The word ''galangal'', or its variant ''galanga'' or archaically ''galingale'', can refer in common usage to the aromatic [[rhizome]] of any of four plant species in the [[Zingiberaceae]] (ginger) family, namely:
* ''[[Alpinia galanga]]'', also called ''greater galangal'', ''lengkuas'', ''Siamese ginger'' or ''laos''
* ''[[Alpinia officinarum]]'', or ''lesser galangal''
* ''[[Boesenbergia rotunda]]'', also called ''Chinese ginger'' or ''fingerroot''
* ''[[Kaempferia galanga]]'', also called ''kencur'', ''black galangal'' or ''sand ginger''

The term ''galingale'' is sometimes also used for the rhizome of the unrelated ''sweet cyperus'' (''[[Cyperus longus]]''), traditionally used as a folk medicine in Europe.
