Functional Evaluation of Five Sideritis Species Traditionally Consumed as Herbal Teas: Enzyme Inhibitory Activities Relevant to Neurodegenerative and Metabolic Disorders.
Article in Chemistry & biodiversity, 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
The growing interest in plant-based medicines has increased attention toward medicinal plants as therapeutic agents. This study evaluated the antidiabetic and anticholinesterase potentials of five Sideritis species through α-amylase, α-glucosidase, AChE, and BChE inhibition assays, followed by LC-MS/MS profiling of the most active extracts. Sideritis montana subsp. montana dichloromethane extract exhibited the strongest α-amylase inhibition (82.38% ± 0.09%), while no extract showed notable α-glucosidase activity. Moderate AChE inhibition was observed in Sideritis lanata (18.78 ± 0.91%), whereas BChE inhibition was more pronounced in Sideritis argyrea (44.96% ± 0.15%) and S. lanata (38.23% ± 0.08%) dichloromethane extracts. LC-MS/MS analysis revealed chlorogenic acid, rosmarinic acid, and quinic acid as major constituents, especially abundant in butanol and water extracts of Sideritis hololeuca, S. lanata, and Sideritis libanotica. Dichloromethane fractions were richer in mid-polarity phenolics such as 4-OH-benzoic, syringic and vanillic acids. Overall, the results highlight species- and solvent-dependent bioactivity, suggesting Sideritis taxa as promising sources of natural enzyme inhibitors.
