If you've been to my site, you'll notice that I have long reported the health benefits of lemons. Packed with nutrients, lemons are one of the most widely used tropical fruits in the world. Their positive reputation mainly comes from their high concentrations of vitamin C. But it's not just the lemon fruit that's beneficial. When used as an essential oil, lemon oil can be applied topically, used for cleaning, and used for many other applications.
Lemon essential oil, also known as Citrus limon oil, is extracted from lemon peels, which have many volatile oil glands in their pits.1 Approximately 1,000 lemons are needed to produce one pound of lemon oil.2 The citrus scent of lemons comes from a chemical compound called limonene, which comprises the majority of lemon oil.3
Lemons were used by ancient Indians, Egyptians and Romans as a remedy for infectious diseases. Today, they are commonly grown in Europe and the United States, and are used in various products.

Composition of Lemon Oil
Limonene makes up majority of lemon oil (about 50 to 70 percent). Lemon oil contains organic compounds, such as pinene, terpinene and terpineol, and non-volatile compounds.
Lemons are packed with a potent nutritional profile and are a low-glycemic fruit. The fruit contains citric acid, which is a natural preservative and makes up 8 percent of the lemon. Lemons are also excellent sources of vitamin C or ascorbic acid, a potent water-soluble antioxidant. In spite of their acidic nature, they have an alkalizing effect when metabolized in your body.6
Lemons also have phenomenal antioxidant properties due to unique flavonoid compounds. In a study published in the Journal of Food Composition and Analysis, lemons, as well as other citrus fruits, contain a dominant flavonoid class called flavanones, such as hesperidin and eriocitrin.
These nutrients are found to have anti-inflammatory and free-radical quenching properties. Lemons also contain other antioxidants, such as alpha- and beta-carotenes, beta-cryptoxanthin, zeaxanthin and lutein. Other nutrients that can be found in these citrus fruits are:
Folate and B-vitamins
Pectin (a type of fiber)

How to Make Lemon Oil
Lemon oil is made by cold-pressing the peels. Heat processing, as opposed to cold pressing, negatively affects the quality of the oil by stripping its nutrients, flavor and color. Because of this, cold-pressed oils have higher quality and price. Lemon oil can also be produced through distillation. Distilled lemon oil is used in soluble essences in lemon drinks. However, this type of lemon oil has an inferior scent compared with its cold-pressed counterpart.

Is Lemon Oil Safe?
It is advisable not to use lemon oil without diluting it first, as it can irritate skin. It must be used with a carrier oil for direct application to skin.9 Effective carrier oils include coconut oil, olive oil and jojoba oil.
There are findings showing that lemon oil may promote photosensitivity, which increases your sensitivity to the sun and may lead to sunburn and uneven darkening of the skin. I also recommend you to avoid applying lemon oil and other citrus oils to your skin when outdoors, as blistering may occur.
People with sensitivities should use essential oils with caution. Reactions can vary from person to person. Some may experience skin reactions, while some may have respiratory problems.10 Consult your physician first before use. Pregnant women and children should also see a doctor before applying lemon oil.
