'''''Ononis''''' is a large [[genus]] of [[perennial plant|perennial]] [[herb]]s and shrubs from the [[legume]] family [[Fabaceae]]. The members of this genus are often called '''restharrows''' or '''wrestharrows'''<ref>{{cite book|last=Stockoe|first=W.J.|title=The Observer's Book of Wild Flowers|publisher=Frederick Warne & Co. Ltd.|edition=1965|page=78}}</ref> as some species grow as weeds on arable lands whose tough stems would stop the [[harrow (tool)|harrow]]. They are natively distributed in Europe.

In [[herbalism]] restharrow is used to treat bladder and kidney problems and water retention.

The [[active ingredient]]s in restharrow are [[essential oils]], [[flavonoid]]-[[glycosides]], and [[tannins]].

Restharrows are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including the [[grey pug]] and ''[[Coleophora ononidella]]'' (which feeds exclusively on ''O. arvensis'').{{Citation needed|date=August 2010}}
