10 Benefits of Citrus Sinensis Essential Oil

Anti-anxiety

Orange essential oil can potentially provide great relief for anxiety symptoms. One study tracked 40 people’s anxiety before and after inhaling the oil. The results showed that the oil decreased the subjects’ anxiety levels.

While more research is needed to prove substantial evidence, this study suggests citrus sinensis essential oil can be a tranquilizing supplement for those who need it.[1]

Antioxidant

You can never have too many antioxidants, whether internally or topically. One research study shared that the antioxidant activity of orange essential oil stems from primarily two sources: First, its d-limonene activity.[2] Second, the peel’s flavonoid activity.[3]

While the antioxidant activity ranges up to 30 percent in this study, it’s still significant enough to note and use as a source of antioxidants. Other great essential oils with antioxidant activity are lime (hystrix essential oil) and lemon oil (citrus limon).

Antibacterial

Cold pressing orange peels to create orange and other citrus essential oils releases tons of antibacterial properties.[4]

According to one study tracking the essential oil’s antibacterial impact on fish bacteria, the limonene element is what gives the strong antibacterial aspect to citrus sinensis essential oil.[5]

Antimicrobial

Sweet orange essential oil contains a wide spectrum of antimicrobial activities.[6] So much so that it was able to fight off e.coli, a common food microbe, in one study.[7]

Plus, the antimicrobial effect is beneficial for your skin too. Citrus sinensis essential oil reduced acne lesions by up to 75 percent in another study.[8] There were minor side effects in this study, such as redness. However, these signs disappeared a few minutes after application.[9]

Anti-Inflammatory

Orange essential oil contains anti-inflammatory effects that come from the peel of the citrus fruit. One study with orange peel extracts showed that, when taken internally, it had as much anti-inflammatory impact as ibuprofen.[10] This does not suggest that you should take orange essential oil internally (please don’t!), but it does shed light on the powerful nature of the oil’s primary ingredient. Of course, more specific studies are needed.

Skin Lightening

Orange essential oil is known as a natural skin lightener. Although, it’s been informally studied and lacks significant scientific research to back it up. Still, this benefit can be helpful if you’re trying to reduce the appearance of scars or even out your skin tone.

So far, lemon essential oil is the main skin lightening essential oil that studies have focused on, and they’ve come back with promising results.[11] However, you can add citrus sinensis essential oil to your blends if you desire a lightening effect, among other benefits.

Mood-boosting

Citrus sinensis essential oil shows high signs of improving mood.

One study monitored two groups of female patients in a dentist office’s waiting room. The first group received orange essential oil diffused air, while the second group just had regular air. The first group, with orange-scented air, reported lower levels of anxiety and overall improved moods.[12]

Increases Sex Drive

If you need an extra boost in the bedroom, orange oil can help. While bitter orange essential oil has more evidence supporting its ability to increase female sex drive,[13] sweet orange essential oil has shown some promising evidence too.

In research using flies, exposure to orange essential oil increased male sex drive.[14] This suggests the potential for further studies with orange essential oil and increasing human sex drive as well.

Repels Insects

No matter what time of year it is, insects are attacking your skin outside or trying to break into your house to get inside. Luckily, sweet orange essential oil can repel insects and protect your home. One study even tracked the repellent activity of orange oil for flies, cockroaches, and mosquitoes. It noted that the oil was beneficial to repel them and was most effective 60 minutes after spraying.

Additionally, cockroaches were the most deterred by the oil.[15]

Boosts your immune system

Thanks to the chaos of daily life, it can be difficult to stay on routine and keep healthy. Therefore, your immune system may flux quite a bit. However, orange essential oil can help boost your immune system via its antioxidant component.[16] In short, by helping to strengthen your blood capillaries, this oil encourages your immune system to grow stronger too.[17]

Also, one study suggested that this oil can help regulate and stabilize your immune system directly. It tested a blend of oils, including orange, and noted their immune-modulating effects.[18]
