Latin Name : Citrus AurantifoliaPart Of Plant Used : Fruit PeelSource : MexicoExtraction Method : Cold ExpressionLime Essential Oil is obtained from Citrus aurantifolia, also known as Mexican or West Indian lime, as well as sour lime.  The oil is extracted from the peel of the unripe skin by   cold expression or from the peel and/or the whole ripe   fruit by steam distillation. Lime oil has a sharp, citrus   smell that immediately perks up one's mood on smelling it, and is pale yellow to light olive in colour.Lime oil, when used in an oil burner, stimulates a tired   mind and helps ease anxiety, apathy, and depression. It is useful to reduce fevers associated with colds, sore   throats, and flu. It increases immunity while easing coughs, bronchitis, sinusitis, and asthma. It is said to be helpful for  arthritis, rheumatism and poor circulation, as well as for obesity and cellulite. This oil is good for the skin; it reduces oiliness and acne, helps with herpes, insect bites and cuts. However, the oil that is obtained by cold expression (as opposed to steam distillation) can cause photosensitivity and irritate the skin.
