10 Benefits and Uses of Orange Oil
Whether sweet or bitter, orange essential oil has tons of benefits for the body and mind.
For centuries, oranges have been seen as a symbol of luck in various cultures.
China was the first country to officially discover how citrus oil could be extracted and used to treat certain ailments, although ancient myths and legends also alluded to the mystique of this vibrant fruit.
Its power as a medicinal extract sees it used to improve skin health, combat bacteria and reduce inflammation, with research into its natural properties unearthing new and exciting discoveries.
We'll explore several uses and properties of this citrus extract, including its effects on health and wellness.
What is orange oil?This extract comes in many different forms, as various iterations are derived from separate parts of the orange tree, native to China, and its similar species. For example, you will find that sweet orange, mandarin oil, orange blossom oil (also called neroli) and petitgrain (extracted from the leaves of the bitter orange tree) are just some of the types made available to buy. However, sweet orange (Citrus Sinensis) and bitter orange (Citrus Aurantium) are generally considered to be the most common form. These extracts are mid-to-light orange in colour and are cold pressed from the peel of the orange fruit, producing a similar sweet, citrusy scent. |
How does orange oil work?
It is believed that this substance contains a natural ability to boost immunity and reduce the symptoms of several ailments, including stress, acne and other health concerns.
When used topically, orange essential oil can help to improve the appearance, health and texture of skin, by promoting smoothness, radiance and clarity.
This can reduce the signs of ageing and ease the symptoms of certain skin conditions.
One of the main advantages in aromatherapy is the cheerful, uplifting scent that can work as both a mood booster and as a relaxant.
Its natural properties may also prove useful in eliminating airborne bacteria and strengthening the immune system.
What are the benefits of orange oil?
This extract may be useful to:
1. Combat germs and bacteria
The active ingredient of orange oil is limonene, which is commonly used in cleaning products. Scientific research into its antibacterial properties have also produced promising results.
For example, a study published in 2012 [1] found that E. coli contamination in foods could be prevented by using orange oil.
An earlier study [2] also concluded that the oil was able to inhibit the spread of salmonella.
It is said that these extracts are effective at repelling ants, a common pest that is attracted to food wastage.
By mixing the extract with distilled water in a glass spray bottle, you can try this method at home, spritzing the solution on shelves, surfaces and in other areas where ants might be attracted to.
2. Reduce inflammation and blood pressure
Research has found that this substance may be able to reduce systolic and diastolic blood pressure.
A 2014 study [3] concluded that compared to fresh air, when the oil was inhaled it offered protection against the damage caused by a spike in blood pressure.
And, according to some research, [4] sweet orange may be able to reduce the pain levels of patients with fractured limbs.
This is because the soothing properties work to turn off reactions that are responsible for causing swelling in muscular tissue.
As a result, this helps to prevent a negative reaction around injured joints and muscles, whilst soothing associated pain.
3. Lower anxiety levels
Orange essential oil is a popular choice in aromatherapy due to its calming properties, which can help to naturally reduce anxiety levels.
Some studies suggest it can help people feel more relaxed, including pregnant women worried about labour.
Adding a few drops to a diffuser is an easy way to enjoy its aromatherapeutic effects, whilst adding to warm bather water or burning a scented candle also works just as well.
4. Improve skin health
Whilst there are many different types of orange oil, most are considered bad for the skin due to their phototoxicity, which means you should only ever use sweet orange.
And even though you should only apply sweet orange to your skin in the evening to reduce the risk of skin damage, it still has a lot to offer.
Its cleansing properties can help to purify the skin, whilst also reducing the signs of ageing by increasing elasticity thanks to its ability to boost collagen production.
It could help to reduce the appearance of acne due to its soothing properties, which researchers discovered in a 2012 study [7] .
5. Inhibit cancer and oxidative stress
Some research suggests that compounds found in this extract may have potential health benefits, including effects on certain types of cells.
However, it is important to note that these studies were done in a test tube and not in the human body, so further research is needed.
6. Enhance exercise performance
Athletes – whether professional or amateur – are always looking at ways to improve and better performance levels.
Some scientific research has been published that suggests orange essential oil could play a role in improving lung function.
A small study found that athletes who inhaled the scent showed improved running times and lung function.
7. Promote weight loss
There are some suggestions that this extract may be able to promote weight loss, although research to date has only been conducted on animal subjects.
A small study found that athletes who inhaled the scent showed improved running times and lung function.
Elevated cortisol levels can cause food cravings, especially for salty, fatty and sweet foods, so inhaling this scent may be able to help with weight management.
8. Boost immunity levels
This extract is rich in vitamin C, which can not only be very beneficial for skin but also the immune system.
When your body receives vitamin C it helps to move white blood cells to the site of infection, helping to enhance the body's defence mechanisms.
While it may not cure a cold, it might help reduce its duration.
9. Encourage better sleep
Perhaps one of the lesser-known uses of orange oil is to encourage better sleep.
Many people diffuse it to help them relax and unwind, which could also be beneficial for those who struggle to close off their thoughts at night.
Some studies suggest it may help with sleep issues.
You can try this at home by diffusing it shortly before you go to bed at night to create a calming atmosphere that relaxes the mind, helping you to drift off without too much interruption.
10. Enhance oral health
The properties also mean it could possess the ability to fight bacterial growth, helping to protect teeth and gums from infections.
Some people mix the oil with water and salt to make their own mouthwash, which may be able to offer some relief from a sore throat.
Another option is to try coconut oil pulling by combining pure coconut oil with a dew drops of orange essential oil.
Simply swish around your mouth and spit the mixture out when finished, and this can help to prevent cavities and bad breath.
