AROMA-NT: Essential Oils and Wearable TENS Device for Chronic Nausea (AROMA-NT)

July 17, 2026 updated by: Subhankar Chakraborty, Ohio State University

AROMA-NT: Assessment of the Mechanisms of Action of Inhaled Essential Oils and Wearable TENS Unit Device on Nausea

This study will investigate how two inhaled essential oil products (QueaseEASE and STILL) and a wearable transcutaneous electrical nerve stimulation (TENS) device (ReliefBand) affect chronic nausea and anxiety in adults with longstanding nausea. The goal is to better understand the mechanisms by which these non-prescription therapies may influence nausea, anxiety, sleep, pain, autonomic symptoms, and bowel-related symptoms.

Participants will first complete a 2-week baseline period during which nausea and other symptoms are assessed through questionnaires. Participants will then use the inhaled essential oil products as needed for 12 weeks while completing symptom surveys. Afterward, participants will use the ReliefBand wearable TENS device as needed for an additional 12 weeks and continue completing surveys. Researchers will compare symptom changes during the intervention periods with baseline measurements to better understand factors that contribute to chronic nausea and how these therapies may provide relief. Up to 250 participants may be enrolled to achieve approximately 100 participants completing both intervention phases

Detailed Description

Chronic nausea is a complex symptom that may be influenced by multiple factors, including anxiety, stress, sleep disturbance, pain, autonomic nervous system function, and bowel-related symptoms. Although inhaled essential oil products and wearable transcutaneous electrical nerve stimulation (TENS) devices are used by individuals experiencing nausea, the mechanisms through which these interventions may affect nausea and related symptoms are not well understood.

The primary purpose of this prospective study is to investigate the mechanisms by which inhaled essential oils and a wearable TENS device influence nausea in adults with chronic nausea and anxiety. Rather than evaluating treatment efficacy, the study is designed to examine whether use of these interventions is associated with changes in potential contributors to nausea, including anxiety, stress, sleep disturbance, pain, autonomic symptoms, and bowel-related symptoms.

Participants will complete a 2-week baseline assessment period followed by a 12-week inhaled essential oil phase and a 12-week wearable TENS device phase. Throughout the study, participants will complete patient-reported assessments of nausea and related symptoms. Changes in symptom domains during the intervention periods will be compared with baseline measurements to identify potential pathways through which these interventions may influence the experience of chronic nausea.

A secondary objective is to evaluate the relationship between changes in nausea severity and changes in fatigue, appetite, and quality of life. Findings from this study are expected to improve understanding of the biological and symptom-based factors associated with chronic nausea and to provide insight into how inhaled essential oils and wearable TENS therapy may affect these factors.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Sequential Essential Oil and TENS Intervention
All participants complete a 2-week baseline assessment period followed by 12 weeks of use of inhaled essential oil products (QueaseEASE for nausea and STILL for stress or anxiety) as needed. Participants then complete 12 weeks of use of a wearable transcutaneous electrical nerve stimulation (TENS) device (ReliefBand) as needed for nausea. The study is designed to evaluate changes in factors that may contribute to chronic nausea, including anxiety, stress, sleep disturbance, pain, autonomic symptoms, and bowel-related symptoms. Participants serve as their own controls through comparison with baseline assessments.
Participants will use two commercially available inhaled essential oil products during a 12-week intervention period. QueaseEASE, containing peppermint, ginger, lavender, and spearmint essential oils, will be used as needed for nausea. STILL, containing sweet orange, ylang ylang, lavender, and bergamot essential oils, will be used as needed for stress or anxiety. Participants may use either or both products according to their symptoms. The intervention is being studied to evaluate potential mechanisms through which inhaled essential oils may influence nausea and related symptom domains, including anxiety, stress, sleep disturbance, pain, autonomic symptoms, and bowel-related symptoms.
Other Names:
  • QueaseEASE
  • STILL
participants will use the ReliefBand wearable transcutaneous electrical nerve stimulation (TENS) device during a 12-week intervention period following completion of the inhaled essential oil phase. The device is worn on the wrist and delivers electrical stimulation to the median nerve. Participants will use the device as needed for nausea and will not use the inhaled essential oil products during this phase. The intervention is being studied to evaluate potential mechanisms through which wearable TENS therapy may influence nausea and related symptom domains, including anxiety, stress, sleep disturbance, pain, autonomic symptoms, and bowel-related symptoms.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Anxiety Severity as a Potential Mechanism of Chronic Nausea
Time Frame: Baseline through 3 months
Change in anxiety severity from baseline during inhaled essential oil use assessed using the Generalized Anxiety Disorder-7 (GAD-7) questionnaire. Modulation of anxiety severity is hypothesized as a mechanism by which Inhaled essential oils affect chronic Nausea
Baseline through 3 months
Change in Anxiety Severity as a Potential Mechanism of How TENS Units Affect Chronic Nausea
Time Frame: Change from 2nd baseline to 3 months after using TENS unit
Change in anxiety severity from baseline during wearable TENS device use, assessed using the Generalized Anxiety Disorder-7 (GAD-7) questionnaire. Modulation of anxiety severity is hypothesized as a mechanism by which TENS units affect chronic Nausea
Change from 2nd baseline to 3 months after using TENS unit

Secondary Outcome Measures

Measure Description
Time Frame
Change in Autonomic Symptom Burden as a Potential Mechanism by which Inhaled Essential Oils Affect Chronic Nausea
Time Frame: Baseline to 3 months
Change in autonomic symptom severity from baseline during inhaled essential oil use assessed using the COMPASS-31 questionnaire. This will evaluate if the change in autonomic symptoms from baseline could be a mechanism by which inhaled essential oils can affect chronic nausea.
Baseline to 3 months
Change in Autonomic Symptom Burden as a Potential Mechanism by which TENS units Affect Chronic Nausea
Time Frame: Second Baseline to 3 months after using TENS unit
Change in autonomic symptom severity from baseline during TENS unit use assessed using the COMPASS-31 questionnaire. This will evaluate if the change in autonomic symptoms from baseline could be a mechanism by which TENS units can affect chronic nausea.
