The Lemon tree was originally a small thorny evergreen tree native to India. It is now common in Southern Europe, Florida and California. The fruit was well known in Europe by the middle ages, and the Greeks and Romans were advocates of its properties. Lemon Oil has been historically recognized as a cleanser, and Lemons themselves reached the height of fame when the British Navy began using citrus fruits to counteract the effects of scurvy. Lemon Essential Oil has a strong bright, zesty lemon scent.
