Lime juice is a good source of vitamin C, though not nearly so good as orange juice. In the 18th century, English ships began to carry lime juice to prevent scurvy. English ships came to be called lime-juicers, and their sailors (and Englishmen in general) lime-juicers or limeys.
Limes are native to eastern Asia. They are cultivated in tropical and subtropical regions. In the United States they are grown mainly in California and southern Florida.
The lime is Citrus aurantifolia of the rue family, Rutaceae.
