Tangerine Essential Oil
Also known as: Tangerine essential oil, Tangerine oil, Mandarin oil, Citrus peel oil, Citrus reticulata essential oil
Overview
Tangerine essential oil, derived from the peel of the *Citrus reticulata* fruit through cold pressing or steam distillation, is a volatile plant oil primarily used in aromatherapy. It is characterized by its pleasant citrus aroma, largely due to its main chemical constituents, including limonene, gamma-terpinene, and myrcene. This essential oil is widely applied for its potential psychological effects, such as anxiety reduction, mood enhancement, and relaxation. Beyond aromatherapy, it is also utilized topically as a skin penetration enhancer in cosmetic formulations. While research on citrus essential oils is moderate, specific high-quality randomized controlled trials (RCTs) focusing solely on tangerine oil are limited, with much of the evidence stemming from broader citrus oil studies or aromatherapy blends. It is generally considered safe for topical and inhalation use when properly diluted.
Benefits
Tangerine essential oil, particularly as part of broader citrus oil aromatherapy, is associated with reductions in anxiety and improvements in mood. A 2023 systematic review and network meta-analysis, though focusing on *Citrus aurantium* (a close relative), indicated effectiveness in reducing state and trait anxiety scores, albeit with low to very low quality evidence and high heterogeneity. While direct tangerine-specific data are less robust, citrus oils may offer mild analgesic and anti-nausea effects. Some evidence supports anxiety reduction in clinical populations, such as cancer patients undergoing treatment, though these studies often use lavender or mixed oils. Effects on anxiety typically manifest within weeks of aromatherapy intervention, often within four weeks, with potential diminishing returns over longer durations. The strength of evidence for tangerine oil specifically is moderate, often extrapolated from studies on other citrus oils or aromatherapy blends.
How it works
The primary mechanism of action for tangerine essential oil involves its volatile compounds interacting with the olfactory system upon inhalation. This interaction modulates activity within the limbic system, which is crucial for mood and anxiety regulation. When applied topically, components of the oil, such as limonene, penetrate the stratum corneum, enhancing skin permeability and potentially facilitating systemic absorption. While the exact molecular targets are not fully elucidated, these terpenes may indirectly influence neurotransmitter systems. The oil's rapid skin penetration without accumulation and quick olfactory uptake contribute to its effects on the central nervous system.
Side effects
Tangerine essential oil is generally recognized as safe when used in diluted form for aromatherapy or topical application, with no serious adverse events reported in high-quality trials. Common side effects, occurring in more than 5% of users, include mild skin irritation or sensitization if applied undiluted, and transient headaches or nausea in sensitive individuals. Uncommon side effects (1-5%) include a risk of photosensitivity, though tangerine oil contains lower levels of furanocoumarins compared to other citrus oils like bergamot. Rare side effects (less than 1%) include allergic contact dermatitis. No significant drug interactions have been documented, but caution is advised with photosensitizing medications. Contraindications include avoiding undiluted topical use on sensitive skin. Due to limited safety data, caution is recommended in pregnant women and children, with professional guidance advised for these populations.
Dosage
The minimum effective dose for tangerine essential oil is not well established. Aromatherapy studies typically recommend using 2-5 drops in a diffuser or a 1-3% dilution for topical application. Optimal dosage ranges for topical use are generally 2-5% dilution, while inhalation exposure is often recommended for 15-30 minutes per session. There is no formal maximum safe dose, but undiluted application to the skin should always be avoided. Timing considerations usually involve sessions of 15-30 minutes, once or twice daily, for up to four weeks. For aromatherapy, cold-pressed oil is recommended, and oxidized or adulterated oils should be avoided. Skin penetration is enhanced by carrier oils, and inhalation efficacy depends on concentration and exposure time. No specific cofactors are required, but carrier oils are recommended for topical use.
FAQs
Is tangerine essential oil safe for daily use?
Yes, generally it is safe for daily use if properly diluted and used intermittently, following recommended guidelines for application and duration.
Can it replace anxiety medications?
No, tangerine essential oil is not a substitute for prescribed anxiety medications. It may serve as an adjunct therapy but should not replace pharmacotherapy.
How quickly does it work?
Effects on mood and anxiety may be noticed within days to weeks of consistent use, particularly when used in aromatherapy sessions.
Is it effective alone or only in blends?
Most evidence comes from studies on broader citrus essential oil blends or general aromatherapy. While it can be used alone, its efficacy in blends is more widely studied.
Does it cause photosensitivity?
Tangerine essential oil has a lower risk of photosensitivity compared to some other citrus oils, but caution is still advised, especially before sun exposure.

- https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2023.1144404/full – This systematic review and network meta-analysis evaluated the anxiolytic effects of various essential oils, including *Citrus aurantium*, a close relative of tangerine. It found that *Citrus aurantium* essential oil was effective in reducing state and trait anxiety scores, though the evidence quality was low to very low with high heterogeneity across studies. The findings suggest potential benefits of citrus oils for anxiety but highlight the need for more rigorous research.

It concluded that aromatherapy, particularly with lavender and other oils, significantly reduced anxiety (SMD ~ -1.12). Both inhalation and massage methods were found effective. While the study showed moderate quality evidence for aromatherapy's benefits, it noted high heterogeneity and limited specific data for tangerine oil.
