NCT05024136

Brief Summary

In this study, subjects with depression/anxiety inhaled the essential oil, which contained sedative, soothing, and relaxing active ingredients to stimulate the olfactory nerve. The essential oil further transmitted to the limbic system that controls emotions in the brain, and then affected the human's mood. The natural aroma can not only awaken the limbic system's memory of aroma but also reflect the subconscious area of the brain, with physiological changes (such as controlling blood pressure, breathing, heartbeat, stress changes, memory, and hormonal coordination.) This study monitors the subject's autonomic nerve parameters before and after aromatherapy to obtain the olfactory cerebral nervous system to convey the message. When the study finishes, we expected to help the subject to relax and soothe the mind.

Outcome Measures

Primary Outcomes (2)

  • The aromatherapy measure autonomic nerve parameter SDNN (standard deviation of all normal to normal intervals index)

    one month

  • The measure blood pressure (SBP and DBP)

    values change of systolic and diastolic BPs

    one month

Study Arms (2)

Placebo

ACTIVE COMPARATOR

Subjects take 30 mins aromatherapy of Limon essential oil per time, a total of 3 times for the month.

Device: Limon essential oil aromatherapy

Experimental

EXPERIMENTAL

Subjects take 30 mins aromatherapy of vetiver essential oil per time, a total of 3 times for the month.

Device: Vetiver essential oil aromatherapy

Interventions

Subjects receive three times 30 mins aromatherapy of Limon essential oil per time for the month. Anthropometric measurements such as blood pressure (systolic blood pressure \[SBP\] and diastolic blood pressure \[DBP\]), autonomic nerve parameters including a. SDNN (standard deviation of all normal to normal intervals index); b. HRV(heart rate variability); c. LF(0.04-0.15 Hz)and HF(0.15-0.4 Hz)were measured every week. PSQI(Pittsburgh sleep quality index)and HADS (Hospital Anxiety and Depression Scale) were measured initial and ten ends.
