Onobrychis viciifolia, also known as O. sativa or common sainfoin (/ˈsænfɔɪn/) was an important forage legume in temperate regions until the 1950s. During the Green Revolution it was replaced by high yielding alfalfa and clover species. Due to its anthelmintic properties, common sainfoin is a natural alternative to drugs to control nematode parasitism in the guts of small ruminants. This is the main reason why O. viciifolia returned to the scientific agenda in recent years.
