A double-blind, placebo-controlled investigation of the acute effects of Essence ring aromatherapy on sleep using actigraphy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aromatherapy may represent a low-cost intervention for disturbed sleep that presents minimal risks as compared with alternative pharmacotherapies. Confirmation of effectiveness and an understanding of the mechanism of action are necessary to support clinical applications. The present study evaluated the impact of two odorants (lavender and peppermint) on sleep behavior using a double-blinded, placebo-controlled design. Consistent with the marketed aromatherapy uses of these odorants, lavender was expected to improve sleep while peppermint was expected to enhance arousal and disrupt sleep. Fifty-nine undergraduate students completed two sleep sessions, 1 week apart, during which active or placebo aromatherapy was initiated at their intended sleep time. A wrist-worn tracking device was used to quantify sleep behavior in their typical sleep environment. Both lavender and peppermint aromatherapy significantly disrupted sleep relative to placebo as measured by reduced minutes asleep, Supplementary Information: The online version contains supplementary material available at 10.1007/s41105-025-00608-6.
