Unraveling the Cold Property of Gardeniae Fructus: Material Basis and Biological Mechanisms.
Article in International journal of molecular sciences, 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
In traditional Chinese medicine (TCM), Gardeniae Fructus is classified as a "cold" herb, a property that is increasingly explained by modern research showing that it can alleviate related disorders through modulation of the central nervous and endocrine systems, energy metabolism, and gut microbiota. This study aimed to elucidate the material foundation and biological mechanisms underlying its cold property. Chemical components of Gardeniae Fructus were separated via multi-stage extraction and characterized by GC-MS and LC-MS, yielding four distinct fractions: aliphatic, iridoid, crocin, and polysaccharide. In a rat model of heat syndrome induced by levothyroxine sodium, administration of the total extract or individual fractions over 15 days modulated central nervous, endocrine, and energy metabolism indicators, with the iridoid, crocin, and polysaccharide fractions demonstrating significant cold properties. Gut microbiota analysis revealed that the total extract, polysaccharide, and iridoid fractions notably reshaped microbial structure, reducing Firmicutes and Lactobacillus abundance. These findings indicate that the iridoid, crocin, and polysaccharide fractions may be key material bases for the cold property of Gardeniae Fructus, with the iridoid fraction exhibiting the strongest effect.
