History
In the United Kingdom, the first major use of lemons was on board ships to ward off scurvy but it was also employed to treat malaria and typhoid. The history of the lemon is not clear although there are references to it going back to the first century B.C.

Although lemon trees grow wild in the Mediterranean (to a height of about 6 metres) they are in fact natives of Asia but are now cultivated in a number of other countries around the world. The oil is produced by cold pressing from fresh peel.
