Lemon essential oil (Citrus limon) is cold expressed from the rinds of the fruit. In order to get a kilo (2.2 lbs) of oil, 3,000 lemons are required.
Lemon essential oil has many uses since it has the following properties: anticancer, antidepressant, antiseptic, antifungal, antioxidant, antiviral, astringent, invigorating, refreshing, and tonic.
It is used primarily for air pollution, anxiety, atherosclerosis, bites/stings, blood pressure (regulation), brain injury, cold sores, colds (common), concentration, constipation, depression, digestion (sluggish), disinfectant, dry throat, dysentery, energizing, exhaustion, fever, flu, furniture polish, gout, greasy/oily hair, grief/sorrow, gum/grease removal, hangovers, heartburn, intestinal parasites, kidney stones, lymphatic cleansing, MRSA, overeating, pancreatitis, physical energy, postpartum depression, purification, relaxation, skin (tones), stress, throat infection, tonsillitis, uplifting, varicose veins, and water purification. See Modern Essentials for many other uses for lemon essential oil.
Historically, lemon has been used to fight food poisoning, malaria and typhoid epidemics, and scurvy. (In fact, sources say that Christopher Columbus carried lemon seeds to America—probably just the leftovers from the fruit that was eaten during the trip.)
