It’s also a great oil to diffuse in a child’s room to encourage a good night’s rest.

What is orange oil?
Orange oil, or orange essential oil, is a citrus oil that’s extracted from the fruit of sweet orange trees. 
These trees, which are native to China, are easy to spot due to the combination of dark green leaves, white flowers and, of course, bright orange fruit.

Sweet orange essential oil is extracted from the oranges and rind that grow on the Citrus Sinensis species of orange tree. 
But there are several other types of orange oil available too. 
They include bitter orange essential oil, which comes from the rind of the fruit of Citrus Aurantium trees.

Other types of orange essential oil include neroli oil (from the flowers of Citrus Aurantium), petitgrain oil (from the leaves of Citrus Aurantium), mandarin oil (from Citrus Reticulata Blanco), and bergamot oil (from Citrus Bergamia Risso and Piot).

Summary: Orange essential oil is just that, oil from oranges. 
There are several different orange oils, depending on the type of orange tree they’ve been sourced from, as well as the part of the tree. 
Sweet orange oil, bitter orange essential oil and mandarin oil are just a few of the different types of orange oil that exist.

What is in orange oil?
Orange oil is just that, orange oil. 
More specifically, it’s extracted from either the fruit or the rind, or both, of oranges using a method called cold pressing.

This particular pressing process involves using pressure to gently squeeze every drop of oil from the orange fruit or rind. 
Some products also contain the flowers and leaves from orange plants too.

As with all essential oils, some orange essential oils contain nothing but pure orange oil, such as Miaroma’s 100% pure orange oil. 
Given the undiluted nature of these products, they need to be blended with a carrier oil (orange oil blends well with frankincense, citronella and ginger) or combined with a cream to avoid skin irritations and reactions. 
It’s also possible to buy products that contain orange oil that’s been combined with other complementary oils, such as Tisserand’s Total De-Stress Diffuser Oil, which also contains geranium and nutmeg.

Summary: Most orange oils contain oil that’s been taken from the fruit, rind, flowers or leaves of orange plants. 
Some orange oils contain 100% pure orange oil while others can contain a combination of ingredients, including orange oil.

Is orange oil good for skin?
It’s not uncommon for certain essential oils to have beneficial properties because of their ability to combat the appearance of redness in the skin. 
As far as orange oil’s concerned, sweet orange essential oil in particular has been proven to have strong cleansing capabilities. 
Other citrus oils with this ability include grapefruit and bergamot.

A 2014 study in Complementary Therapies in Medicine concluded that orange oil’s antimicrobial effects may be beneficial for people with blemishes. 
The study focused on 28 volunteers, who were divided into four groups. Each of these groups were given a different topical gel to apply to their skin over an eight-week period. 
The study concluded that all four gels, one of which included a blend of sweet orange essential oil and basil, reduced blemish symptoms by 43 to 75%.

What are the benefits of using essential orange oil?
Orange essential oil has been associated with several health benefits, particularly when it comes to using it for aromatherapy.

Some aromatherapy practitioners believe inhaling it or absorbing it through the skin transmits messages to the region of our brain that processes our emotions and regulates the autonomic nervous system. 
This system is responsible for how fast our heart beats and regulating blood pressure, as well as how little/much we sweat and how our gut functions.

When used in aromatherapy, it’s believed orange essential oil may help with one or more of the following:

-Colds and flu
-Depression
-Constipation
-Stress

USES OF ORANGE OIL
Structural Pest Control
In the United States, d-Limonene (Orange Oil) is an EPA approved and registered active ingredient in California and Florida for the extermination of Drywood Termites, Formosan Termites, and other structural pests. 
Orange Oil is the active ingredient of the popular structural termiticide XT-2000. 
Regarded an alternative to traditional fumigation, d-Limonene Orange Oil is increasing in popularity as approximately 70% of modern consumers in California prefer local structural chemical injections over traditional "tenting" or fumigation.

Biological pest control
Orange oil can be used in green pesticides for biological pest control. 
Orange Oil can exterminate or control ants and other insects by erasing their scent-pheromone trail indicators, or melting their exoskeleton, eliminating the infestation or disrupting re-infestation.

Orange oil is also known to be useful to control, but not exterminate Drywood termites (Incisitermes), killing only those who come into direct contact with it.

Domestic Cleaning Agent
Orange oil is used as a cleaner. 
Orange Oil is also used as an additive to certain wax finish/polish such as Howard's Feed-N-Wax Wood Polish & Conditioner.

Aromatherapy material for humans
In the practice of aromatherapy, orange oil is described as providing various benefits, including the possibility of "reducing stress", controlling "anxiety", enabling "relaxation" and "lifting mood". 
Aromatherapy is a pseudoscience, and much of the purported evidence cited for these claims comes from research which is not double-blinded or controlled.

The uses of Orange Essential Oil are abundant, ranging from medicinal and odorous to cosmetic. 
Orange oil's many forms include oils, gels, lotions, soaps, shampoos, acne treatments, sprays, deodorants, and candles.

Used in aromatherapy applications, Orange Essential Oil can deodorize while exuding its own fresh and energizing scent. 
Simply inhaling the scent of the Orange oil from the bottle has a sedative, relaxing effect that simultaneously reduces anxiety and contributes to the feeling of being alert. 
Orange Oil can be diffused throughout a room by adding 5-6 drops in a diffuser on low heat. 
This is reputed to boost the mood and even improve digestion. 
To ease both physical and mental fatigue, mix 5 drops of Sweet Orange Essential Oil and 5 drops of Lavender Essential Oil in a diffuser. 
Inhaling the scent of Orange Essential Oil is also known to relieve the nasal irritation associated with seasonal allergies, as it eases sinus congestion, headache, and itchiness. 
While travelling, Orange Oil can be sniffed from either the bottle or from a soaked cotton ball just as the first symptoms of irritation begin in the nose.

Orange Oil can be added to the laundry to scent clothing, or it can be added to the dishwasher. 
To scent the kitchen in particular with a warm, clean Orange blend, fill a pot with water and add 1-9 drops of Orange Essential Oil along with either Lemon Essential Oil or Lemon rinds, Cinnamon sticks, and Cloves. 
Allow this blend to simmer on the stove. 
Alternatively, blend Orange, Lemon, Cinnamon, and Clove essential oils in an electric diffuser.

Used in cosmetic applications, Orange Essential Oil is known to enhance the complexion, especially for those who suffer from eczema. 
For a natural moisturizer, combine 1-2 drops of Orange Essential Oil with 1-3 tsp. of a carrier oil such as Organic Almond, Olive, Coconut, Hemp, Jojoba, or Macadamia. Apply this mix to the skin to reduce the appearance of wrinkles and dark spots and to encourage collagen production. 
Orange Essential Oil can also be combined with other oils such as Frankincense Essential Oil and Tea Tree Essential Oil, which are known to facilitate the healing of skin.

For skin afflicted with acne, Orange Essential Oil can be combined with a small amount of Coconut Carrier Oil on a cotton ball and applied to the affected areas – or areas that seem like they might begin to breakout. 
This mix is reputed to eliminate bacteria, soothe inflammation, reduce pain and swelling associated with acne, and prevent dryness. 
For an even higher effectiveness, Orange Essential Oil can be blended with Geranium Essential Oil or Cinnamon Essential Oil. 
After it has been determined that skin will not have a negative reaction to Orange Essential Oil, a few drops of the oil may also be added to a warm bath or to a body wash. 
For an acne spot-treatment, a cotton swab dipped directly in Sweet Orange Oil can be dabbed onto affected areas of skin to reduce the bacteria that contribute to and worsen acne. 
1 drop of Orange Oil can also be mixed with Organic Aloe Vera gel before being dabbed onto blemishes and wrinkles.

For a cleanser that reduces blemishes and unwanted spots without dehydrating the skin, Orange Oil can be combined with Honey. 
To create this anti-bacterial, anti-inflammatory acne treatment, blend together 1 Tbsp. Organic Coconut Carrier Oil, 3 Tbsp. Raw Honey, 1 Tbsp. Apple Cider Vinegar, 20 drops Orange Essential Oil, and 2 capsules of Live Probiotics. With a hand blender, combine all these ingredients, then pour them into a glass bottle and store it in a cool, dark, dry place until it is ready for use.

For a simple yet deeply cleansing face wash that reduces the amount of oil on the skin and controls acne breakouts, a nightly tonic can be made by adding 2-3 drops of Orange Essential Oil to 1 cup of water. 
This mixture can be used to wash the face before going to bed. 
For those who apply makeup to the skin, 3-4 drops of Orange Oil can be combined with a 1 Tbsp. of a light carrier oil such as Olive or Sweet Almond before the blend is applied to the face with a cotton ball or cotton pad. 
Before wiping it off, allow the oil to sit on the skin for 5 minutes.

Used in hair, a combination of Orange Essential Oil and Honey is known to eliminate bacteria, to reduce dandruff and itchiness by restoring moisture, and to balance the scalp’s pH without removing any of its vital natural oils. 
For a shampoo that achieves all of the aforementioned, combine 1 cup water, 5 Tbsp. Raw Honey, 5 drops Orange Essential Oil, and 5 drops Lemon Essential Oil in a bowl before transferring the blend to a glass dispenser bottle. 
Shake the bottle well before each use and apply this shampoo as normal.

Used in medicinal applications, Orange Essential Oil can reduce inflammation, promote relaxation, and enhance circulation. 
Combining it with a carrier oil and massaging it into the abdominal area is reputed to facilitate and improve digestion, which eases or prevents cramps and constipation. 
For higher effectiveness, Orange Essential Oil can be combined with Peppermint or Spearmint essential oils before it is diluted with a carrier oil and massaged into the belly.
Orange Oil is known to have diuretic properties, thus massaging it into the belly also promotes the release of toxins, especially from the digestive tract, while stimulating the bladder and lymphatic system.

Orange Oil’s anti-inflammatory properties can offer relief to those who suffer from pain and swelling in the joints. 
For a soothing balm that addresses the symptoms of arthritis, melt 1 Tbsp. of Coconut Carrier Oil over low heat, then mix in 10 drops of Orange Essential Oil. 
Apply this salve to affected areas until it is completely absorbed into the skin. 
Similarly, to reduce symptoms of edema – better known as fluid retention – warm 3 Tbsp. of Sesame Seed Carrier Oil and mix in 10 drops of Sweet Orange Essential Oil. This blend can be massaged into swollen feet and ankles until completely absorbed. 
Alternatively, Orange Oil can be used in a foot soak: Add a mixture of 2 Tbsp. Sea Salt and 10-15 drops of Orange Essential Oil to a basin of warm water and soak the feet for 20-30 minutes. 
For facial edema, a similar blend can be made by adding 1 tsp. of Sea Salt to a cup of warm water and stirring in 5 drops of Sweet Orange Essential Oil. 
This can be applied to the face with cotton balls that have been dipped into the mixture and placed on the cheeks and under the eyes. 

To improve digestion, mix 3-4 drops of Orange Essential Oil with 1 tsp. of Olive Carrier Oil and massage it into the abdominal area. 
This will encourage digestive enzymes to be released, which will subsequently improve digestion and thereby prevent or relieve gas and constipation.

Benefits of orange essential oil:

-Antimicrobial activity
A 2012 study looked at the effect of orange essential oil on E. coli isolates obtained from beef. 
These isolates can potentially cause food poisoning. 
Results indicated that after 24 hours, a 1 percent or lower concentration of orange essential oil inhibited the bacteria at refrigeration temperatures.

Another study looked at the effect of orange essential oil on strains of Staphylococcus aureus (staph bacteria) that are resistant to antibiotics. 
They found that when added to infected human cells in culture, low concentrations of orange essential oil killed the bacteria without harming the cultured cells.

Orange essential oil may also prevent the growth of fungi that can cause food to spoil. 
One study found that orange oil provided some protection against four species of fungi.

Another study recorded activity against eight fungi that affect vegetables, although essential oils like clove and garlic were more effective.

-Anxiety and depression
Aromatherapy with orange essential oil appears to reduce symptoms of anxiety and depression.

In a 2013 study, it was found that aromatherapy with orange essential oil reduced the pulse rate and stress hormone levels in children undergoing a dental procedure.

Additionally, in a 2015 study, women in labor reported less anxiety after inhaling orange essential oil than women in the control group who inhaled distilled water.

A 2019 study on mice looked at the inhalation of orange essential oils and its potential effect on depression. 
The researchers found that the mice who inhaled the orange essential oil displayed fewer depression-like behaviors.

-Pain relief
A 2017 study involving people with bone fractures looked at whether inhaling orange essential oil could help with pain. 
Compared to a control group, people inhaling orange oil reported less pain.

In 2008, researchers assessed if a blend of ginger and orange essential oil could help with knee pain when applied to the skin. 
Compared to a control group, people using the essential oil blend reported greater short-term pain relief, but the oil didn’t seem to help with long-term pain.

-Anticancer and antioxidant activity
Limonene, a component of orange essential oil, has been investigated as a potential cancer treatment. 
A study from 2012 found that orange oil rich in limonene both inhibited the growth and promoted the death of colon cancer cells in culture.

A 2017 study found that orange essential oil inhibited the growth of lung and prostate cancer cell lines in culture. 
Additionally, increased cell death was seen in the lung cancer cell line. 
Orange essential oil was also observed to have antioxidant activity.

-Exercise performance
A small 2016 study evaluated the effect of inhaled orange flower essential oil on exercise in student athletes. 
The researchers found that people who inhaled the oil had a significant decrease in running times as well as an increase in lung function.

Due to the small size of the study, more research is needed to support this benefit.

-Weight loss
A 2019 study on rats evaluated if orange essential oil could promote weight loss. 
They found that obese rats that were fed capsules of orange essential oil showed a reduction in weight gain as well as lowered cholesterol.

More research is needed to determine if orange essential oil can have the same effect on humans.

-Insecticide activity
A 2012 study looked at the effect that orange essential oil had on housefly larvae and pupae. 
It was found to have insecticidal properties by both contact and fumigation.

DEFINITION
Orange oil is an essential oil produced by cells within the rind of an orange fruit (Citrus sinensis fruit). 
In contrast to most essential oils, it is extracted as a by-product of orange juice production by centrifugation, producing a cold-pressed oil.
Orange oil is composed of mostly (greater than 90%) d-limonene, and is often used in place of pure d-limonene. D-limonene can be extracted from the oil by distillation.

Orange essential oil is extracted from the rind of the sweet orange, Citrus sinensis. 
This is done by a method called cold pressing, which uses pressure to squeeze the oils from the rind. 
Sometimes, the leaves and flowers from the orange plant can be used as well.
Research has shown that some essential oils may have specific health benefits.
Orange oil (Citrus sinensis) is a pure, natural essential oil and is used as a flavoring as well as in aromatherapy for its bright and refreshing citrus scent and flavor. 
When used as a flavoring, use sparingly as essential oils are potent.
Appropriate for use in chocolates and coatings (typical use is ¼ to ½ teaspoon per pound)  
All of our essential oils are appropriate for therapeutic use and are quality tested and lot-coded for quality assurance and tracking. 

Composition
The compounds inside an orange oil vary with each different oil extraction. 
Composition varies as a result of regional and seasonal changes as well as the method used for extraction. 
Several hundred compounds have been identified with gas chromatograph-mass spectrometry. 
Most of the substances in the oil belong to the terpene group with limonene being the dominant one. 
Long chain aliphatic hydrocarbon alcohols and aldehydes like 1-octanol and octanal are second important group of substances. 
The presence of sinensetin, a flavone, explains the orange color.

How to use the oil
-Diffusion
Perhaps you’d like to raise your mood a little? 
Or maybe you’d like to add the refreshing scent of orange to a room? 
Diffusion can help you do that.
A diffuser allows an essential oil to evaporate, typically using heat. 
As evaporation occurs, the scent of the  orange essential oil spreads throughout the room.
There are many types of diffusers you can buy, either online or at specialty stores that sell aromatherapy products. 
Each type of diffuser will have its own specific set of instructions. Be sure to carefully follow all product instructions when using your diffuser.

-Spray
Do you want another way to add an orange scent to a space? 
Or maybe you’d like to use orange essential oil as a natural cleaner? 
You can make an orange oil spray by following these steps:

-Add orange essential oil to water, preferably in a glass bottle. 
The National Association for Holistic Aromatherapy (NAHA) recommends using 10 to 15 drops per ounce of water.
-Although not necessary, adding a dispersing agent such as solubol to the solution can help the oil to better disperse through the water.
-Shake the bottle well to mix the contents.
-Spray as desired.

-Massage oil
Are you looking to relieve pain or inflammation? 
Consider making your own massage oil infused with orange essential oil.
To do this, you’ll need to dilute orange essential oil in a carrier oil, like coconut oil or jojoba oil. 
The NAHA suggests using 20 drops of essential oil per ounce of carrier oil to make a massage oil with a 3 percent solution.

Safety and side effects
Any essential oil has the potential to cause a skin reaction when applied topically. 
If you’re concerned about a possible reaction, test a little bit of diluted orange essential oil on the inside of your elbow before using it on larger areas.

Avoid using old or oxidized orange essential oil, which can cause dermal sensitization. 
This is a type of allergic reaction that may not be noticeable after one use, but it can cause severe reactions after you’ve used it a few times.

Some citrus essential oils are phototoxic. 
This means they can cause a painful skin reaction if you use them on your skin and then go out in the sun.

Orange essential oil has a low risk of phototoxicity, but you should still exercise caution if you plan on going outside after using it on your skin.

As with other essential oils, follow these safety precautions when using orange oil:

-Don’t apply undiluted essential oil to your skin.
-Keep the oil away from your eyes.
-Store the oil out of reach of children and pets.
-If you use the oil for aromatherapy, make sure that the space you’re in is ventilated well.
-If you’re pregnant, breastfeeding, or taking prescription medications, speak to your doctor before using orange essential oil.

HOW IS ORANGE OIL EXTRACTED?
In the peel of a fresh Orange, there are cells that contain the fruit’s volatile fatty oil glands. 
Orange Oil is thus derived from the fruit peel. The extraction process may involve first separating the rinds from the Oranges, then grinding, chopping, or puncturing them before they are pressed. 
The order of events may differ, in that the fruit peels may first be rolled over with a trough in order to pierce the essential oil pouches located on the underside of the peels. 
The liquid that results from this pressing process is a combination of orange juice and orange essential oil, which gradually begin to separate from each other, at which point the essential oil is collected.

In a slightly different extraction process, Orange Essential Oil is a by-product of Orange Juice. 
This process involves the whole fruit being pressed to squeeze the juice and essential oil from the pulp. 
When the essential oil separates from the juice and rises to its surface, the oil is collected through Centrifugation.

Cold-pressing protects the oil’s anti-oxidants and active ingredients from being destroyed by heat. 
After undergoing cold-pressing, some citrus oils are steam-distilled. 
Alternatively, Orange Oil can also be produced through Solvent Extraction, Supercritical CO2 Extraction, and Turbo Distillation. 
After extraction, Orange Oil has an orange-yellow or orange-brown color and gives off the light, fresh, sweet fragrance of the fruit itself.

HISTORY OF ORANGE OIL
Orange Oil, most commonly referred to as Sweet Orange Essential Oil, is derived from the fruits of the Citrus sinensis botanical. 
Conversely, Bitter Orange Essential Oil is derived from the fruits of the Citrus aurantium botanical. 
The exact origin of Citrus sinensis is unknown, as it does not grow wild anywhere in the world; however, botanists believe that it is a natural hybrid of the Pummelo (C. maxima) and the Mandarin (C. reticulata) botanicals and that it originated between the South-West of China and the Himalayas. 
For several years, the Sweet Orange tree was considered to be a form of the Bitter Orange tree (C. aurantium amara) and was thus referred to as C. aurantium var. sinensis.

According to historical sources: In 1493, Christopher Columbus carried Orange seeds during his expedition to the Americas and eventually they reached Haiti and the Caribbean; in the 16th century, Portuguese explorers introduced Orange trees to the West; in 1513, Ponce de Leon, the Spanish explorer, introduced Oranges to Florida; in 1450, Italian traders introduced Orange trees to the Mediterranean region; in 800 AD, Oranges were introduced to eastern Africa and the Middle East by Arab traders and were then distributed through the trade routes. In the 15th century, Portuguese travelers introduced the Sweet Oranges they brought back from China to the woodland areas of West Africa and to Europe. 
In the 16th century, Sweet Oranges were introduced in England. 
It is believed that Europeans valued Citrus fruits mainly for their medicinal benefits, but the Orange was quickly adopted as a fruit. 
Eventually, it came to be cultivated by the wealthy, who grew their own trees in private “orangeries.” The Orange has come to be known as the oldest and the most commonly grown tree fruit in the world.

For thousands of years, Orange Oil’s ability to naturally enhance immunity and reduce several symptoms of numerous ailments have lent it to traditional medicinal applications for the treatment of acne, chronic stress, and other health concerns. 
The folk remedies of the Mediterranean region as well as the regions of the Middle East, India, and China used Orange Oil to relieve colds, coughs, chronic fatigue, depression, flu, indigestion, low libido, odors, poor circulation, skin infections, and spasms. 
In China, Oranges are believed to symbolize good fortune and thus they continue to be a significant feature of the traditional medicinal practices. 
It is not only the benefits of the pulp and the oils that are valuable; the dried fruit rinds of both the Bitter and Sweet varieties of Orange have also been used in traditional Chinese medicine to soothe the aforementioned ailments as well as to address anorexia.

Historically, Sweet Orange Essential Oil had many domestic uses such as when it was used to add the Orange flavor to soft drinks, candy, desserts, chocolates and other sweetmeats. 
Industrially, the anti-septic and preservative properties of Orange Oil made it ideal for use in the production of cosmetics and skin care products such as soaps, creams, lotions, and deodorants. 
For its natural anti-septic properties, Orange Oil was also used in cleaning products such as room freshening sprays. 
In the early 1900s, it was used to scent several products such as detergents, perfumes, soaps, and other toiletries. 
Over time, Sweet Orange Oil and other citrus oils began to be replaced with synthetic citrus fragrances. 
Today, it continues to be used in similar applications and has gained popularity as a sought-after ingredient in cosmetic and health products for its astringent, cleansing, and brightening properties, among many others.

What to look for
Orange essential oil can be purchased either online or at a store that sells natural products. 
Follow the tips below to ensure you purchase good quality orange essential oil.
-Check the label for the scientific name: Citrus sinensis. 
-Bitter orange essential oil is another oil with a very similar name: Citrus aurantium. Don’t confuse the two.
-Verify product purity. 
-You should be buying 100 percent orange essential oil. 
-If this isn’t the case, it should be indicated on the label.
-Choose dark bottles. Essential oil can be damaged by sunlight and dark bottles help prevent this.
-Smell the oil before you buy, if possible. 
-If it doesn’t smell like orange, don’t buy it.
-Stay away from any product that claims on its label or through advertising that it can treat a specific health conditions. 
-The Food and Drug Administration (FDA) doesn’t regulate essential oil like it does medications.

Hazards
The limonene which is the main component of the oil is a mild irritant, as it dissolves protective skin oils. 
Commercial use of orange oil, like that found in XT-2000 requires the use of protective gloves, according to EPA approved labeling and most municipal structural pest control law such as the California Structural Pest Control Act of 2015. 
Limonene and its oxidation products are skin irritants, and limonene-1,2-oxide (formed by aerial oxidation) is a known skin sensitizer. 
Most reported cases of irritation have involved long-term industrial exposure to the pure compound, e.g. during degreasing or the preparation of paints. 
However a study of patients presenting dermatitis showed that 3% were sensitized to limonene.
Limonene is also flammable.
