Lime

(Citrus aurantifolia) has a fresh, sweet citrus scent that is very mentally uplifting and refreshing. It has great restorative properties and has historically been used for cleansing, purifying, and renewing both spirit and mind. Lime essential oil helps strengthen the immune system, reducing the frequency of infections, reducing fevers, and easing coughs and congestion. It is a good skin toner that can also improve the appearance of oily, dull, and blemish-prone skin. Lime is a great addition to household cleaners and air fresheners.
