Lime trees are native to sub-tropical and tropical regions of the world. Lime essential oil for use in cosmetics and perfumes is obtained from the peel of the lime fruit. In our Vanilla/Lime products we use a lime essential oil that is cold expressed (cold-pressed) in Central America. Cold expressing yields a pale yellow liquid that captures the true sweetly fresh aroma of the lime.
Lime essential oil is antiseptic, bactericidal, restorative, tonic, and antiviral. The essential oil of lime can help alleviate acne, asthma, chilblains, colds, dull skin, and varicose veins. The aroma of lime essential oil is uplifting, refreshing, and brings clarity of thought and concentration to the mind.
Natural oils are the best. The best store I have found that sells essential oils is http://www.handsonaromatherapy.com. The have some really nice spa oils as well.
