The Short Answer
Cananga odorata contains a complex essential oil rich in caryophyllene, linalool, benzyl benzoate, and the oxoaporphine alkaloid liriodenine, which exert antimicrobial, anti-inflammatory, and cytotoxic effects through topoisomerase II inhibition and endorphin-pathway modulation. Preclinical evidence demonstrates that nerolidol isomers from its essential oil achieve a 2-log reduction in adherence by clinical strains of Staphylococcus aureus and Klebsiella pneumoniae, while liriodenine shows potent in vitro and in vivo topoisomerase II inhibitory activity, though no human clinical trials have confirmed therapeutic efficacy.

Origin & History
Natural habitat
Cananga odorata is native to the tropical rainforests of Southeast Asia and the Pacific Islands, including the Philippines, Indonesia, Papua New Guinea, and the Comoro Islands. The tree thrives in humid, lowland tropical climates with well-drained soils, typically growing at elevations below 500 meters. It is widely cultivated commercially in Madagascar, Réunion, and the Comoros for its highly aromatic flowers used in the perfume industry, while Pacific Island communities have long utilized its leaves, bark, and flowers for traditional medicine.
“Cananga odorata holds deep cultural significance across Southeast Asia and the Pacific, where its flowers have been used in ceremonial garlands, bridal preparations, and ritual offerings for centuries, particularly in Filipino and Indonesian traditions where the blossoms are strewn on newlywed beds as a symbol of love and fertility. In Papua New Guinean ethnomedicine, fresh leaves are employed as a direct topical remedy for malaria, representing an antivector or symptomatic use rooted in generations of indigenous knowledge. The tree's flowers are the source of ylang-ylang essential oil, which became a cornerstone of European perfumery in the 19th century following its introduction to French Réunion, where it was incorporated into the iconic fragrance Chanel No. 5. In Ayurvedic and traditional Southeast Asian systems, various plant parts including bark, roots, and flowers have been applied to treat skin conditions, fever, asthma, and gastrointestinal complaints, reflecting the broad ethnopharmacological profile that modern phytochemistry is only beginning to investigate.”Traditional Medicine
Scientific Research
The available evidence base for Cananga odorata consists predominantly of in vitro phytochemical analyses, essential oil characterization studies using GC-MS, and limited in vivo animal models, with no peer-reviewed randomized controlled trials in human populations identified to date. A 2023 sub-acute toxicity study evaluated an ethanol extract of C. odorata flowers in an animal model, though detailed results including NOAEL values and organ-specific findings have not been fully published in accessible literature. Studies on liriodenine's topoisomerase II inhibitory activity have been conducted in cancer cell line models and rodent tumor models, providing mechanistic insights but insufficient evidence to establish clinical efficacy in humans. The overall evidence quality is rated as preliminary, and translation of in vitro antimicrobial, antidiabetic, and cytotoxic findings to clinically actionable conclusions requires well-designed human trials.
Preparation & Dosage
Traditional preparation
**Fresh Leaf Topical Application (Traditional)**
Fresh leaves are bruised or crushed and massaged directly onto the skin; this Papua New Guinean practice targets malaria and is undosed in the clinical literature, with no standardized protocol established.

**Note**
No evidence-based supplemental dosage range exists for any oral, topical, or inhalation form of C. odorata; all preparation methods described reflect research or traditional contexts only.
Nutritional Profile
Cananga odorata is not consumed as a food source and therefore does not provide meaningful macronutrient or micronutrient content in dietary quantities. The plant's pharmacological relevance derives from its essential oil and secondary metabolite profile: the essential oil is composed of approximately 42.3% sesquiterpene hydrocarbons (notably caryophyllene at ~13.5% and α-muurolene at ~8.4%), 18.1% monoterpene hydrocarbons, and significant phenylpropanoid fractions including benzene-1-methoxy-2-methyl- (~28.7%), linalool (~6.4%), benzyl benzoate, benzyl acetate, methyl benzoate, and geranyl acetate. Alkaloids including liriodenine, cananodine, and novel compounds canangone and canangaionoside are present in leaf and bark fractions at trace concentrations that vary with geographic origin, plant part, and extraction methodology. Bioavailability of essential oil constituents via inhalation is rapid due to pulmonary absorption, while dermal penetration varies by molecular size and lipophilicity; oral bioavailability data for isolated constituents from C. odorata specifically are not established.
How It Works
Mechanism of Action
Liriodenine, a cytotoxic oxoaporphine alkaloid isolated from C. odorata, intercalates into DNA and inhibits topoisomerase II, preventing the re-ligation of double-strand DNA breaks and ultimately triggering apoptosis in rapidly dividing cells, a mechanism confirmed in both in vitro cell lines and in vivo animal models. Caryophyllene, a bicyclic sesquiterpene constituting approximately 13.5% of the essential oil, selectively binds to CB2 cannabinoid receptors, thereby downregulating NF-κB-mediated pro-inflammatory cytokine production including TNF-α and IL-6. Linalool and benzene-1-methoxy-2-methyl- modulate GABAergic neurotransmission and stimulate endorphin release, accounting for anxiolytic and sedative properties observed in inhalation models. Nerolidol isomers disrupt bacterial membrane integrity and block surface adhesin-mediated attachment, reducing biofilm formation by clinical isolates of S. aureus and K. pneumoniae by approximately 2 orders of magnitude.
Clinical Evidence
No human clinical trials meeting standard criteria for pharmacological intervention studies have been identified for Cananga odorata as a therapeutic agent. The body of research consists of in vitro bioassays and animal experiments that establish plausible mechanisms but do not provide effect sizes, confidence intervals, or human-relevant dosing data. Traditional use documentation, particularly the Papua New Guinean practice of massaging fresh leaves onto the skin for malaria, represents ethnopharmacological evidence that has not yet been validated through controlled ethnobotanical trials or pharmacokinetic studies. Confidence in therapeutic outcomes remains low due to the absence of Phase I or Phase II clinical data, and all reported benefits should be interpreted within the context of preclinical research only.
Safety & Interactions
Cananga odorata essential oil is generally regarded as safe for use in cosmetics and fragrances at low concentrations (typically below 1–2%), but it is a recognized sensitizer; the International Fragrance Association has set use restrictions due to its capacity to cause allergic contact dermatitis, particularly from constituents such as isoeugenol and benzyl benzoate. A 2023 sub-acute toxicity study on an ethanol flower extract in an animal model was identified in the literature, but detailed NOAEL values, organ toxicity data, and maximum tolerated dose findings have not been made publicly available in accessible peer-reviewed form. No formal drug interaction studies have been conducted; however, the sedative and GABAergic properties of linalool suggest theoretical additive effects with CNS depressants including benzodiazepines, barbiturates, and opioids when inhaled in high concentrations. Cananga odorata preparations are not recommended during pregnancy or lactation due to insufficient safety data, and topical use on broken or inflamed skin should be avoided given the sensitization potential of its phenylpropanoid constituents.

Frequently Asked Questions
What is ylang-ylang (Cananga odorata) used for medicinally?
Cananga odorata has been used in traditional medicine across Papua New Guinea, the Philippines, and Indonesia for conditions including malaria, fever, skin infections, and anxiety. Phytochemical studies identify antimicrobial, anti-inflammatory, cytotoxic, and insect-repellent activities driven by compounds including liriodenine, caryophyllene, linalool, and nerolidol isomers. However, no human clinical trials have confirmed these uses, and all evidence remains at the preclinical or ethnobotanical level.
What are the main active compounds in ylang-ylang essential oil?
The essential oil of Cananga odorata is dominated by benzene-1-methoxy-2-methyl- (~28.7%), caryophyllene (~13.5%), α-muurolene (~8.4%), and linalool (~6.4%), alongside benzyl benzoate, benzyl acetate, methyl benzoate, and geranyl acetate. Sesquiterpene hydrocarbons collectively account for approximately 42.3% of the oil, while monoterpene hydrocarbons contribute about 18.1%. The alkaloid liriodenine, found in bark and leaf fractions, is pharmacologically notable for its topoisomerase II inhibitory activity.
Is ylang-ylang essential oil safe to use on skin?
Ylang-ylang essential oil is a recognized skin sensitizer and should always be diluted to 1–3% in a carrier oil before topical application; undiluted use can cause allergic contact dermatitis in sensitized individuals. The International Fragrance Association restricts its use in cosmetic products due to sensitizing constituents such as isoeugenol and benzyl benzoate. Individuals with known fragrance allergies, pregnant women, and those with compromised skin barriers should exercise particular caution or avoid use.
Does ylang-ylang have any scientifically proven benefits?
Cananga odorata demonstrates several well-characterized activities in laboratory settings, including a 2-log reduction in Staphylococcus aureus and Klebsiella pneumoniae biofilm adherence by nerolidol isomers, potent topoisomerase II inhibition by liriodenine in cancer cell lines, and CB2-mediated anti-inflammatory effects from caryophyllene. These findings are scientifically credible but derived from in vitro and animal models only; no randomized controlled trials in human populations have been completed, meaning clinical proof of benefit is currently absent.
How was ylang-ylang traditionally used in Papua New Guinea for malaria?
In Papua New Guinean traditional medicine, fresh leaves of Cananga odorata are massaged directly onto the skin as a remedy associated with malaria management. This application likely leverages the insect-repellent and antivector properties of the essential oil constituents, including benzyl benzoate and geranyl acetate, which may deter Anopheles mosquitoes. The practice is documented as ethnobotanical knowledge but has not been evaluated in controlled clinical or entomological studies to confirm efficacy or establish a standardized protocol.
Is ylang-ylang essential oil safe to use during pregnancy and breastfeeding?
Ylang-ylang essential oil should be used cautiously during pregnancy and breastfeeding, as safety data for these populations is limited. While traditional use exists, pregnant and nursing women should consult a healthcare provider before internal or topical application, and inhalation should be done in well-ventilated areas only. The ingredient is best avoided as a supplement during these critical periods unless specifically recommended by a qualified practitioner.
Can ylang-ylang interact with medications, particularly those affecting the nervous system or immune function?
Ylang-ylang essential oil may potentially interact with sedatives, blood pressure medications, and immunosuppressants due to its antimicrobial and CB2-receptor-related properties. Individuals taking prescription medications, especially those for cardiovascular or central nervous system conditions, should inform their healthcare provider before using ylang-ylang supplements. Direct medical consultation is recommended to assess individual risk factors and medication compatibility.
What is the difference between ylang-ylang essential oil and ylang-ylang extract supplements, and which form is more effective?
Ylang-ylang essential oil is a concentrated volatile extract typically used for aromatherapy and topical application, while ylang-ylang extracts in supplement form are often standardized to specific active compounds like nerolidol and caryophyllene. Essential oil provides faster sensory effects but offers less consistent dosing, whereas standardized extracts provide controlled compound levels suitable for clinical study of antimicrobial and anti-inflammatory benefits. The choice depends on the intended use: aromatherapy favors essential oil, while research-backed internal supplementation favors standardized extracts with defined active constituent percentages.
