Does aroma influence Indigenous and local people's selection and utilization of plants? A scoping review.
Review in Journal of ethnobiology and ethnomedicine, 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
backgroundThe influence of morphological traits on the selection and utilization of plants has been widely investigated, but explaining how people recognize a plant's usefulness based on chemistry has been challenging. Plant aroma, as a perceptual indicator of underlying chemical composition, may play an important role in this process, yet its contribution remains insufficiently understood.
methodsWe conducted a review of literature published over the past 50 years to examine the role of plant aroma and human olfaction in shaping plant selection and perceived utility within Indigenous and local knowledge systems. We assessed patterns of interdisciplinarity by combining qualitative content and co-occurrence analyses with matrix-based heatmap visualizations.
resultsWe find that aroma contributes, to some extent, to the selection and utilization of plants by facilitating preliminary identification, therapeutic classification, and intergenerational knowledge transmission. However, the mechanisms underlying this relationship remain poorly understood mainly due to the lack of interdisciplinary approaches and methodological limitations in most studies.
conclusionsLimited integration across disciplines constrains definitive conclusions, underscoring the need for more rigorous interdisciplinary research. We propose integrating phytochemistry with standard ethnobotanical data collection to better understand the role of plant aroma and olfactory perception in plant selection.
