Tilia Tomentosa promotes sleep, preserving sleep structure.
Article in Npj biological timing and sleep, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Tilia extracts have been used for centuries for their relaxing and hypnotic properties; however, their impact on the sleep-wake cycle and sleep architecture remained elusive. In this study, we investigated the effects of a chronic treatment with Tilia tomentosa extracts on the sleep-wake cycle and the associated neuronal activity, using chronic electrophysiological recordings in freely moving mice. We found that Tilia treatment induced a significant increase in NREM sleep and a concomitant reduction of wakefulness during the nocturnal (active) hours, in treated mice compared to controls. Furthermore, the treatment significantly reduced brief awakenings during light (resting) hours. Tilia did not cause alterations of the essential electrophysiological features of the EEG signal. Moreover, Tilia administration did not impair either the homeostasis or the structure of the sleep-wake cycle. Spectral analysis reported mild changes in high gamma and theta bands in Tilia-treated mice compared to controls. Altogether, our data provide preliminary evidence that Tilia favours sleep and reduces sleep fragmentation, without interfering with the physiological structure of sleep and the associated neuronal activity.
