Pha Chế & Hòa Hợp
(+)-Limonene (63.1%) and γ-terpinene (12.5%) deliver a bright citrus aroma associated with positive hedonic response and stress-reduction via limbic-pathway modulation in inhalation studies of citrus-family EOs.
Ref: class-extrapolation from limonene-dominant citrus EOs (sweet orange, grapefruit, bergamot FCF); Tisserand & Young 2014, Ch.13
Yuzu EO inhibited NDMA formation by 22–59% in vegetable models and 24–62% in saliva ex vivo, attributed to radical-scavenging activity of limonene-class and γ-terpinene constituents.
Ref: Sawamura et al. (2005), J Agric Food Chem 53(9):3411–3416
(+)-Limonene has demonstrated GST induction and tumour-inhibition in animal models; yuzu's high limonene content (63.1%) places it within the anticarcinogenic-class citrus cluster per T&Y Ch.14.
Ref: class-extrapolation from limonene-dominant citrus EOs; Sawamura et al. (2005)
d-Limonene administered orally showed gastric mucosa protective activity in rat models; yuzu's dominant limonene (63.1%) provides the constituent basis for gentle digestive support in abdominal massage.
Ref: Kodama et al. (1977b), Yakugaku Zasshi 97(7):705–712
Citrus peel EOs rich in (+)-limonene have shown cortisol-marker reductions in controlled inhalation studies; yuzu's aromatic profile supports equivalent limbic-pathway modulation.
Ref: class-extrapolation from limonene-dominant citrus EOs; Tisserand & Young 2014, Ch.13
γ-Terpinene (12.5%), elevated above typical citrus EOs due to C. ichangensis parental inheritance, is a potent free-radical scavenger in vitro, supporting mild antioxidant activity in topical formulations.
Ref: class-extrapolation from γ-terpinene constituent data; Tisserand & Young 2014, Ch.13
AI-summary
No RCT-grade clinical trials have been conducted specifically on Citrus junos (yuzu) EO in human aromatherapy settings. The strongest available evidence is Sawamura et al. (2005), demonstrating significant NDMA inhibition (22–59% in vegetable models; 24–62% in saliva ex vivo), supporting antioxidant and anti-nitrosamine activity attributed to limonene-class constituents. Reproductive safety is supported by Kodama et al. (1977) d-limonene rat metabolism studies, cited by Tisserand & Young (2014, p.909–910) as basis for 'pregnancy not hazardous' classification. All other therapeutic actions are class-extrapolations from structurally similar limonene-dominant citrus EOs.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3–5 drops per 100 ml water | Mood-uplifting ambient use; 30–60 min sessions. Ultrasonic or nebulising diffuser. Avoid prolonged inhalation at high concentration. Use fresh, refrigerated oil to minimise oxidised-limonene exposure. |
| Topical massage | 1–3% in carrier oil | Blend with jojoba or sweet almond. Maximum 3% leave-on formulation; 5% adult cap per T&Y. Precautionary UV avoidance 12 h post-application despite non-phototoxic classification (Sawamura 2009). |
| Inhalation (direct) | 1–2 drops on tissue or inhaler stick | For on-the-go stress relief or nausea. Inhale 30–60 s. Do not apply undiluted to skin. Replace inhaler after 5–7 days; limonene-rich oils oxidise rapidly on air exposure. |
| Bath (dispersed) | 4–6 drops pre-dispersed in 15 ml carrier oil | Premix with carrier before adding — never add undiluted to bath water (mucous membrane irritant risk). Evening wind-down blend; water temperature ≤ 38 °C to preserve volatile top note. |
| Skincare blending | 0.5–1% in moisturiser, serum, or facial oil | Non-phototoxic (Sawamura 2009) — daytime safe unlike most citrus EOs. Use 0.5% for sensitive, 1% for normal/mature skin. Fresh, refrigerated oil only to prevent oxidised-limonene sensitisation. |
