Native to Asia, the lemon tree is a small evergreen whose genetic origins have been traced back to a cross between bitter orange and citron. The exact details of its journey from the wilds to civilization are not precisely known but it is believed that lemon trees were first introduced in Europe around 200 A.D. The dimpled, yellow fruit took another 1,300 years to spread across the globe, from the Middle East to Northern Africa, then eventually to the Americas with Christopher Columbus in 1493.
Originally cultivated as an ornamental plant, in time Citrus limon became so much more than something pretty to look at. Lemons are antioxidant powerhouses, containing twice as much Vitamin C as the average orange as well as several unique citrus phytochemicals which have been studied for their potential to prevent cancer and other chronic diseases. As a flavoring for food and drink, lemon’s pucker-inducing tartness and sweet-sour flavor profile have made it a favourite ingredient in the culinary arts. Chock-full of limonene and citric acid, its juice is an excellent anti-bacterial, de-greasing, deodorizing, and disinfecting household cleanser.
Without a doubt, lemons have a lot going for them. But the saga of the little fruit that could doesn’t end there. As an essential oil, lemon is a popular choice due to its citrusy, uplifting scent that just makes things smell clean. Cold-pressed from the peel, lemon oil has antifungal, astringent, and antiseptic properties, making it an exceptionally practical oil that would be well-placed in any essential oil collection. Read on to learn more about lemon oil’s suite of benefits, from the ways it can promote health and wellness to how it can be used to naturally clean and freshen the home.
1. Treat Candida Infections
Most commonly expressed as a yeast infection when it’s running rampant, Candida is a class of fungus that is often a normal part of good oral and intestinal health. Its overgrowth, however, can affect the skin, throat, mouth, genitals, and, if left untreated, can even invade the blood.
Because of its antifungal properties, lemon oil can be used as a natural remedy for yeast infections. A recent study found that lemon oil was able to inhibit the growth of various Candida strains. This is likely because of lemon oil’s high monoterpenoid content, which has an antimicrobial effect. You can use the following recipe as an external skin treatment once per day. If there’s no improvement after a week, you should see a healthcare practitioner.
Recipe: 3 cups of lukewarm water + 2 tablespoons of vinegar + 3 drops of lemon oil + 4 drops of tea tree oil
2. For Pain Relief
According to the American Academy of Pain Medicine, chronic pain affects 100 million Americans – more than diabetes, heart disease, and cancer combined. The four most common kinds of pain are lower back pain, severe headache / migraine, neck pain, and facial aches. Whether the pain is long-lasting or short-lived, sharp or throbbing, a result of physical injury, inflammation, or medical issue, it can absolutely interfere with your quality of life.
There are many options available to treat and manage pain, but a natural way to reduce pain signals in the brain was found with lemon oil aromatherapy. The study, published in 2002, was conducted on lab rats during a persistent experience of pain; the rats that inhaled the aroma of lemon oil showed a decrease in behaviors indicative of pain (flinching, flexing, and licking the affected area) as compared with the control group. Researchers measured the rats’ neuronal activity and found that lemon oil increased the expression of c-Fos, a gene and protein that regulates nerve cell production and survival.

3. Enhance Mood & Concentration
If you have ever deeply inhaled the scent of lemon oil, you’ve probably noticed that it has a stimulating, and yet calming, influence in the mind. In an effort to better understand the relationship between smell and mood, researchers examined the psychological and physiological impact of smelling either lemon oil, lavender oil, or plain water before and after experiencing a stressor. Of the 56 healthy volunteers, those that smelled lemon oil reported increased positive mood – despite having their hands plunged in ice water! The researchers also measured stress hormones and found that norepinephrine, which plays a role in cognition and learning, was maintained at elevated levels after inhaling lemon oil.
4. Lessen Stress & Anxiety
One of the great paradoxes of lemon oil is its ability to invigorate and relax. In addition to its anti-depressant and cognition-boosting qualities, lemon oil aromatherapy was shown to calm the nerves and relieve stress in two separate studies.
Using various animal models for assessing anxiety, despair, and exploratory behaviors, researchers in a 2006 study exposed mice to lavender, rose, and lemon essential oils and found that lemon had the “strongest anti-stress effect”. Another study, this time concerning rats, resulted in lowered corticosterone levels (which is released as a stress response) when exposed to lemon oil for a period of two weeks.

5. Lose Weight
It may seem like a bold statement, but lemon oil can actually help you lose weight by suppressing weight gain, dissolving body fat, and reducing appetite. The rind of many citrus fruits – including lemon – contain high amounts of the organic compound limonene. Limonene has the ability to facilitate lipolysis – the breakdown of white adipose tissue, which is the type of fat the body stores for energy. The connection between limonene and lipolysis was demonstrated in a study where exposure to a blend of lemon oil and grapefruit oil aromatherapy increased lipolysis and reduced body weight in lab rats.

6. Alleviate Morning Sickness
Affecting more than half of moms-to-be, the vomiting and nausea of pregnancy is among the least pleasant aspects of gestation. While morning sickness will usually subside on its own within 14 to 18 weeks, for some it will continue for the whole nine months, up until the time the baby is delivered.
Fortunately, there is some respite to be found with lemon oil! A clinical trial from 2014 examined the effects of lemon oil aromatherapy on pregnant women who suffer from morning sickness. Involving more than 100 participants, the study determined that inhaling lemon oil as soon as feelings of nausea were present had the effect of drastically reducing queasiness and retching as well as an overall decrease in the intensity of those symptoms.
7. Skin Toner
Lemon oil is an astringent – meaning that it constricts bodily tissues when applied topically. For this reason, lemon oil may be used for deep cleansing of the skin while also shrinking pores. Terrific for oily skin types, lemon oil acts as a natural toner that reduces the amount of sebum (oily or waxy substances) produced by the sebaceous glands. Since overactive sebaceous glands are a major cause of acne, cysts, hyperplasia, and other inflammations of the skin, adding lemon oil to your daily skin care regimen can help heal and prevent breakouts.

Remember: Lemon oil is phototoxic, meaning that it will increase your skin’s sensitivity to sun light and cause you to burn faster!
8. Degrease Your Hair
Also caused by an overzealous sebaceous gland, greasy hair can leave your tresses limp, flat, and stringy no matter how much you wash it. As with oily skin, lemon oil can reduce the amount of sebum on the scalp, as well as help rebalance the production of oils.

9. All-Purpose Cleaner
Although vinegar is a wonderful, eco-friendly cleaner, sometimes you might not want to imbue your home with a sour, pungent smell. Lemon oil’s antiseptic, antifungal, and disinfectant qualities make it a viable green cleaning contender – all while emitting that unmistakably “clean” scent.
Recipe: 2 ½ cups of water + 2 tablespoons of liquid castile soap + 10 to 20 drops of lemon oil
10. Laundry Detergent

11. Wood Polish
The chemicals in commercial wood polishes can irritate the eyes, skin, and respiratory tract. In lieu of introducing pollutants into the home, you can use lemon oil as a key ingredient for all-natural homemade furniture polish that will not only bring back the luster and shine of the wood but also help to protect against future scratches and stains.
Recipe: ½ cup of olive oil or sweet almond oil + 10 to 15 drops of lemon oil
12. Reusable Wipes
If you loathe using paper towels to sop up small spills but still want to have on-the-go disinfecting wipes on hand, then this one’s for you! You’ll need a handful of square cloths (old t-shirts or bed sheets would do the trick) and a suitable container with lid for easy access.
When you’re done using these wipes, simply wash the cloths and reuse them for your next batch of lemon oil disinfecting wipes!
13. Clean Small Wounds
Since lemon oil is a natural antiseptic, it can be used to clean minor wounds to prevent infection. You can use these recipes on superficial cuts, scrapes, and burns to speed up the healing process.
Soothing Salve Recipe: Combine ¼ cup of beeswax pellets with ¾ cup of coconut oil and heat on low on the stovetop. Once thoroughly melted and blended, add 12 drops each of lemon, lavender, and tea tree oil. Transfer to a container and allow it to cool before using.

You can eliminate bad odors and instantly refresh your indoor spaces with a little lemon oil.
Spray Recipe: 1 cup of water + 24 drops of lemon oil
(Be sure to pick up a couple of these sprayers for storage and use of essential oil cleaning fluids!)
Essential Oil Precautions
Like many citrus essential oils, lemon oil is phototoxic. This means that when an essential oil is applied topically, exposure to sunlight (UV rays to be exact) causes the skin to become hyper-sensitive and burn much more easily. It is recommended to stay out of direct sunlight for at least 12 hours after using lemon oil on the skin.
Also, essential oils should always be diluted before using them on the skin. While the aforementioned recipes are good places to start, you may wish to experiment with your own blends. As a general rule, a 2% dilution can be made by mixing 12 drops of essential oil per one ounce of carrier oil, lotion, or butter. When using an essential oil for the first time, it’s wise to perform a small skin patch test before applying it all over your body.
Last but definitely not least, while lemon oil is generally considered safe, most essential oils are not recommended for use by pregnant or nursing women. Many essential oils (including some of those used in the above recipes) contain organic compounds which – while safe for adults – may be toxic or cause severe irritation to infants and small children. While many oils present warnings to this effect within their packaging, not all of them do. Remember: when in doubt, the best practice is always to discuss which essential oils are safe with a licensed obstetrician before use.
