In this double-blind clinical trial, 84 nurses working in the ICU were assigned to two groups.
One group inhaled a drop of Geranium Essential Oil, while the placebo group inhaled one drop of sunflower oil.
During three consecutive shifts, the drops were placed on the nurses’ protective face masks and inhaled for 20 minutes.
Using the Visual Analog Fatigue Scale, fatigue was measured 30 min before the intervention, immediately after, and 60 min later.
The study concluded that fatigue was reduced immediately after inhalation and also 60 minutes after inhaling geranium essential oil when compared to sunflower oil inhalation.
