A sustainable functional food ingredient from Saussurea involucrata cell culture alleviates atopic dermatitis-like inflammation via arachidonic acid metabolic remodeling.
Article in NPJ science of food, 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
Nutritional interventions may complement established approaches for managing atopic dermatitis (AD). Here, we evaluated Saussurea involucrata cell culture (SIC), a sustainable functional-food material, in a DNCB-induced mouse model of AD-like inflammation. Chemical profiling established the phytochemical composition of SIC, and both topical and oral interventions improved macroscopic and histopathological outcomes. Under the tested conditions, the oral groups showed more consistent changes in systemic indices, providing the basis for subsequent mechanistic analyses. Integrated transcriptomic and metabolomic analyses, targeted lipid-mediator profiling, and qRT-PCR identified coordinated changes in the arachidonic acid (AA) metabolic network. Exploratory docking and molecular dynamics provided descriptive computational support for target-dependent retention or reorientation of selected ligand-protein configurations, while tissue-level immunohistochemistry supported corresponding changes in selected AA pathway-associated, type 2 inflammatory, and epidermal-junction proteins. Together, these findings associate oral SIC supplementation with attenuation of AD-like inflammation and AA metabolic remodeling.
