Health Benefits Of Lime Oil

The most noteworthy lime oil benefits include:

1. Effective against cancerous cells

When the body cells grow abnormally, the condition is known as a lump or a tumor. When those abnormal cells spread from one part of the body to the other, they are known as malignant tumors or cancer.

Usually, cells live for a certain period and then, die. But cancer cells don’t die, but only keep multiplying. The oil extracted from Citrus aurantifolia inhibits the growth of colon (intestine) cancer cells by 78%.

D-limonene, limonoids, flavonoids, and D-dihydrocarvone present in the lime essential oil have anticancer properties. The study also says that lime oil can prevent colon cancer, as it works via mechanisms such as DNA fragmentation and apoptosis (2).

2. Fights against bacteria

A study published in 2012 talks about the antibacterial activity of the leaf oil of C.Aurantifolia. According to the study reports, methanol and ethyl acetate present in the oil proved effective against a few disease-causing bacteria like:

  • Bacillus cereus
  • Enterobacter faecalis
  • Escherichia coli
  • Klebsiella pneumonia
  • Pseudomonas aeruginosa
  • Salmonella paratyphi
  • Staphylococcus aureus
  • Proteus vulgaris
  • Serratia marcescens

Also, the antibacterial activity of lime oil is comparable to the standard antibiotics (medicines that help kill bacteria) such as ofloxacin, tobramycin, gentamicin sulfate, and ciprofloxacin (3).

3. Gets rid of free radicals

The compounds ethyl acetate and methanol present in lime essential oil have antioxidant properties.

Antioxidants are the chemical compounds that help in preventing oxidation, a process that forms harmful substances called free radicals. Free radicals cause diseases and fasten aging.

A paper published in the Asian Journal of Biochemical and Pharmaceutical research states that the synergistic effect of bioactive compounds present in the Citrus aurantifolia essential oil contributes to the antioxidant activities.

The study also confirms ethyl acetate and methanol present in lime oil are so potent that they can be used in medicines, which are popular antioxidants.

Another study published in 2018 confirms citrus aurantifolia oil has promising antioxidant properties.

A study published in 2018 states the essential oil obtained from Omani lime leaves is high in D-limonene. Thus, it’s useful in the pharmaceutical industry. Thanks to their safe toxicological profiles. (4)

4. Eases cold symptoms

Due to the rich vitamin C content, the lime essential oil is an immune booster. It helps you prevent and clear infections such as cold, sore throat, bronchitis, and flu.

Flu is a disease wherein there is fever, runny, stuffy nose, fatigue/ weakness, and throat infection.

You may add just a few drops of the oil to your homemade soaps or beauty products. (7)

7. Prevents obesity

A study reports that lime essential oil has anorexic (loss of appetite) properties; thus, it can help in weight loss. Obesity is when you weigh much above your healthy weight. Obesity is one of the common health problems worldwide.

It needs a serious intervention, as it can be deadly because it paves the way for several other diseases.

However, lime oil is reported to facilitate weight loss. During a study, researchers divided mice into two groups. They fed one group of mice with lime oil whereas the other group was left as such.

The group of mice that had lime oil ate less food, and also lost weight in comparison to the other group.

In another study researchers administered lime oil with ketotifen; it opposed the weight gain in mice. Ketotifen is an antihistaminic drug, which has an association with weight gain.

Antihistamines are medicines that reduce allergic reactions such as runny nose and watery eyes.

Few mice had ketotifen for 45 days, and at the end of which the mice ate more, and also weighed higher. Then, the researchers gave lime oil to mice, along with ketotifen during the experimental period.

At the end of it, the results said there was a reduction in weight gain in mice, and also they ate less. These outcomes confirmed that lime oil has anorexia properties. The study suggests lime oil can be useful to deal with drug-induced obesity. (8)

8. Effective against fungi

Citrus aurntifolia oil prevents the growth of the following fungi:

  • Phaeoramularia angolensis
  • Candida albicans
  • Aspergillus parasiticus and its aflatoxins
  • Aspergillus niger

Thanks to the monoterpenes present in the oil. Due to its antifungal actions, C. aurntifolia plant is popular as a fungicide (kills fungi) for the citrus fruit crop. (9)

The research also says that C. aurntifolia plant may be a potential candidate for protecting food and feeds from toxigenic fungal growth and their aflatoxin contamination.

*Aflatoxin is a type of toxin.

9. Relieves muscle spasms

Citrus aurantifolia oil has spasmolytic properties too. When it was tested on the organs of rabbits, the researchers concluded that lime oil has important spasmolytic properties. Researchers studied the spasmolytic effect on smooth muscles.
