Lemon oil is often used in cleaning agents, as it quickly and easily dissolves sticky residues and can clean away difficult grime. Topically, it can cleanse the skin. Aromatically, lemon has powerful uplifting properties. Diffuse, add to cleaning agents, apply directly to difficult-to-clean areas, or apply in 2-5% dilution.
The fruit was well known in Europe by the middle ages, and Greeks and Romans were advocates of its therapeutic properties. Lemon essential oil reached the height of its fame when the British began using the citrus fruit to counteract the effects of scurvy.
