To evaluate the clinical efficacy of aromatherapy incorporating Citrus limon essential oil on the symptoms of patients with motion sickness.
✦ Clinical Takeaway ✦
No actionable change — this self-controlled pre-post trial of lemon aromatherapy for motion sickness is too preliminary, lacks a control group, and has no direct implication for audiological vestibular management.
✦ Why It Matters ✦
Vestibular disorders are within the audiology scope of practice, but this single-arm trial provides insufficient evidence to consider aromatherapy as a clinical tool for vestibular symptom management.
✦ Key Points ✦
- 01Self-controlled (pre-post) trial design — no separate control group, limiting causal conclusions.
- 02Intervention was Citrus limon (lemon) essential oil aromatherapy for motion sickness.
- 03Motion sickness is linked to vestibular-visual conflict, making this tangentially relevant to audiology.
- 04Evidence is too weak to inform any change in vestibular rehabilitation practice.
- 05Further RCTs with control arms would be needed before clinical consideration.
