The patients were allocated to geranium and placebo groups (n = 40 each) using stratified block randomization. On the second day of admission three drops of geranium essential oil and placebo were poured on absorbing patches attached inside the oxygen masks of the geranium and placebo groups, respectively. The patients were asked to inhale the aroma for 20 min a day on two consecutive days.

RESULTS

all stages of the intervention, the two groups had a significant difference in anxiety scores, i.e. geranium aroma caused significantly greater reductions in the anxiety scores (P < 0.001).

CONCLUSIONS
