Lime is a small green lemon with a higher acidity and stronger aroma. Originally found in South-East Asia, it is used in traditional medicine as a source of vitamin C which brings in vitality and rebalances the energy of the human body. In ancient times, lime oil was used to treat infections, colds and fevers. Lime is also well known in aromatherapy for refreshing, revitalising properties and antioxidant benefits. As an astringent, lime can clean and tone skin; it is particularly useful on oily skin or acne-prone skin.
