Lime (Citrus aurantifolia) is a citrus tree with a fruit that contains a very high level of vitamin C. British sailors were issued a daily allowance of lemon or lime juice to prevent scurvy, giving them the nickname Limey.
Limes are small roundish bright green fruit with a pungent flavour. However, if they stay on the tree for a long time they turn yellow and resemble a small roundish lemon. Lime juice is used in cooking and in soft drinks, cocktails and limeade (like lemonade). Lime extracts and essential oils are frequently used in perfumes, cleansing products, and for aromatherapy.
For other kinds of lime, see Lime.
