Effect of aromatherapy with Matricaria chamomilla in pain and anxiety management in hospital settings: A scoping review protocol.
Article in PloS one, 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
introductionPain and anxiety are underestimated complications in hospitalized patients, negatively impacting their well-being and physiological functioning. Integrative and Complementary Health Practices (ICHP) emerge as alternatives or complements to standard treatments, with chamomile aromatherapy highlighted for its sedative, anxiolytic, and analgesic properties.
objectiveThis review aims to map the existing knowledge regarding the use of aromatherapy with chamomile essential oil in the management of pain and anxiety within hospital environments.
methodThis study is a scoping review that adheres to the Joanna Briggs Institute (JBI) guidelines and the PRISMA-ScR checklist. A comprehensive search will be conducted across ten data sources for this review: Medical Literature Analysis and Retrieval System Online (MEDLine/PubMed), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, LILACS, Scielo, Cochrane Library, Scopus, ScienceDirect, Wiley Online Library, and Virtual Health Library (VHL). The selection of studies will include full-text articles, dissertations, theses, ministerial ordinances, and guidelines, while abstracts, letters to the editor, opinion articles, off-topic studies, and duplicates will be excluded.Results will be presented through a PRISMA-ScR flowchart and tables, employing the PAGER methodology to enhance reporting quality.
conclusionAromatherapy with chamomile essential oil shows promising results for managing pain and anxiety in hospital settings. It demonstrates mild analgesic effects and consistent anxiety reduction, especially when administered via inhalation. This review aims to systematize existing knowledge, identify gaps, and provide theoretical and practical support for its safe clinical application, thereby strengthening integrative practices and promoting more humanized care.
