Scurvy is caused by a deficiency in vitamin C, of which the lime happens to be high in, as is its competitor, the lemon. In fact, a lemon is four times higher in vitamin C, but limes were more available in the 19th century (from the West Indies), and became the main fruit of the British navy sailing the high seas. The sailors even acquired the nickname, "limey."
Lime trees grow to about 16 feet high and can be found in tropical and subtropical climates. The origin of limes is not known. Some speculate they may have come from the Indonesian archipelago or nearby Asia. Christoper Columbus is credited with taking the first lime seed to the West Indies where it was planted in 1493. Today limes are grown all over the world. Brazil is the top producer, followed by Mexico, the U.S. (mainly Florida), and the West Indies.
