Observation of Inhalation of CXMCI-01 Essential Oil on Patients With Mild Cognitive Impairment

Participants in the experimental group will inhale 100% CXMCI-01 essential oil twice(CXMCI-01-M in morning, CXMCI-01-N in night) daily for 28 days using an aroma necklace. Each session involves placing 2 drops of the essential oil on a cotton pad inside the necklace. Inhale near the nose for 5 minutes, then wear the aroma necklace and continue inhalation for 60 minutes.

Participants in the placebo group will inhale a 0.1% CXMCI-01 essential oil dilution twice (CXMCI-01-M in morning, CXMCI-01-N in night) ) daily for 28 days. The protocol mirrors the experimental group: inhalation near the nose for 5 minutes, followed by wearing an aroma necklace infused with the diluted essential oil for 60 minutes. This group serves as a placebo comparator to evaluate the effectiveness of the experimental intervention.
