1. Relieves Nausea

If you are looking for a way to get rid of nausea, especially if you are pregnant and experience morning sickness, lemon essential oil serves as a natural and effective remedy.

A double-blind, randomized, controlled trial in 2014 investigated the effect of lemon inhalation on nausea and vomiting during pregnancy. One hundred pregnant women with nausea and vomiting were divided into intervention and control groups, and participants in the intervention group inhaled lemon essential oil as soon as they felt nauseated.

The researchers found that there was a statistically significant difference between the control and intervention groups in the average nausea and vomiting scores, with the lemon oil group having much lower scores. This suggests that lemon essential oil can be used as a tool to reduce nausea and vomiting during pregnancy.

2. Improves Digestion

Lemon essential oil can help to soothe digestive problems, including issues like gastritis and constipation.

A 2009 animal study published in Chemical and Biological Interactions found that when lemon essential oil was given to rats, it reduced gastritis symptoms by reducing the erosion of gastric mucosa (the lining of your stomach) and working as a gastro-protective agent against stomach legions.

And a 10-day randomized control study sought to verify the efficacy of lemon, rosemary and peppermint essential oils on constipation in the elderly. Researchers found that those in the aromatherapy group, who received an abdominal massage using the essential oils, had significantly lower constipation assessment scores than those in the control group. They also found that the number of bowel movements were higher in the experimental group. The natural constipation relief among participants in the essential oil group lasted two weeks after treatment.

3. Nourishes Skin

Lemon essential oil benefits your skin by reducing acne, nourishing damaged skin and moisturizing the skin. Laboratory studies show that lemon oil is able to reduce cellular and tissue damage to the skin caused by free radicals. This is due to the strong antioxidant activity of lemon oil and the anti-aging effects.

According to a scientific review published in Evidence-Based Complementary and Alternative Medicine, lemon essential oil is also effective against skin problems such as blisters, insect bites, oily and greasy conditions, cuts, wounds, cellulitis, rosacea and viral infections. the skin like cold sores and warts. This is due to the antimicrobial compounds in lemon oil that work to treat dermatological conditions naturally.

4. May Promote Weight Loss

Did you know that lemon essential oil may be able to promote the breakdown of body fat? Like grapefruit oil, one of the best essential oils for weight loss, lemon also contains dlimonene, which is known to help support your metabolism and cleanse your lymphatic glands, which can help with weight loss.

An animal study published in the Journal of Clinical Biochemistry and Nutrition found that when mice were supplemented with lemon polyphenols that were extracted from lemon peel for a 12-week period, their body weight gain, fat pad accumulation, and development of hyperlipidemia, hyperglycemia and insulin resistance were significantly suppressed.

5. Helps Purify the Body

Lemon oil has a purifying, cleansing and protective effect on the body. It helps defend the body against harmful pathogens and promotes detoxification through blood and liver. Lemon oil also stimulates lymphatic drainage, which helps the body cleanse itself of waste and toxins.

A 2016 animal study found that when lemon essential oil was administered to rats that had developed acute liver and kidney damage induced by aspirin, it was able to reduce oxidative stress and damage both organs. 

Another study in animals tested the effects of lemon oil and other essential oils on the antioxidant status of organs in mice. When the mice were treated with essential oils for six months, even at very low doses, they were able to reduce oxidative stress and maintain the structural integrity and functional activity of the organs. A mixture of lemon essential oil and ginger extract had the greatest antioxidant effect on the liver and brain in mice.

6. Boosts Oral Health

Being that lemon essential oil has antibacterial and antifungal properties, it works as a natural remedy for many oral conditions, including oral thrush and bad breath. It can also be used to whiten your teeth naturally and prevent tooth decay.

A randomized controlled trial including 90 HIV/AIDS patients evaluated the efficacy of lemon juice in the treatment of oral thrush. Researchers found that the use of lemon juice for oral thrush was validated by its ability to treat the condition in an HIV-positive population.

Although citrus juices are known for their ability to cause tooth erosion after long-term use because of their acidic nature, essential oils do not seem to cause the same acid erosion.

7. Relieves Cough and Stimulates Lymphatic Drainage

Lemon oil has antibacterial, antioxidant and anti-inflammatory properties, so it helps stimulate your immune system and fight respiratory problems. It also serves as one of the main essential oils for allergies.

It is one of the best essential oils for cough because it benefits the lymphatic system, which protects it from harmful pathogens and reduces inflammation of the lymph nodes. The essential oil of lemon also stimulates the lymphatic drainage, what reduces the accumulation of liquids that can cause cough. 

8. Works as Antimicrobial Agent

Studies show that lemon essential oil works as a natural antimicrobial agent because of two dominant compounds found in the oil, limonene and b-pinene. This makes lemon oil a powerful tool in cleaning and food protection.


Lemon oil can be used to clean your home of harmful pathogens, such as bacteria, fungi and other harmful pathogens. Using lemon as a natural cleaning product also keeps your home free of conventional products that are made with dangerous chemicals.

The research also shows that lemon oil can be used to help protect our food system, too. In a study that tested the preservative effects of lemon oil, the researchers discovered that lemon inhibited the growth of bacteria in minced beef. The essential oil of lemon successfully stopped the development of Listeria monocytogenes, which suggests that it plays a role in the prevention of contamination in our food sources. This is useful for our food system because foods contaminated with bacteria such as Listeria monocytogenes, Salmonella, Staphylococcus aureus and Escherichia coli have been reported to cause foodborne illness.
