In vivo and in silico wound healing potential of Cannabis Sativa seed oil through inflammation mediators.
Article in BMC complementary medicine and therapies, 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
backgroundThis study investigates the wound healing potential of Cannabis Sativa seed oil (CSSO), derived from the industrial hemp variety 'NARLI'. The rich essential fatty acid profile of CSSO presents promising therapeutic opportunities; however, its specific in vivo efficacy and targeted molecular mechanisms in wound management remain underexplored. This study aimed to evaluate the in vivo tissue regeneration dynamics and the in silico anti-inflammatory mechanisms of CSSO derived from the 'NARLI' hemp variety in an excision wound model.
methodsUsing an excision wound model, 42 rats were divided into two groups: control (untreated) and CSSO-treated. Wound healing was assessed through clinical wound area measurement, histopathological evaluation, immunohistochemistry (IHC), and molecular docking analyses. Wound area measurements were taken on days 7, 14, and 21.
resultsOn day 21, CSSO-treated animals showed a significantly higher wound closure rate (93%) compared to the control group (87.55%) (p = 0.005). Histopathological analysis revealed enhanced neovascularization, increased collagen deposition (p = 0.008), reduced inflammatory cell infiltration (p = 0.020), and increased epithelial proliferation in the CSSO group. Immunohistochemistry findings showed a marked decrease in proinflammatory cytokines TNF-α and IL-1β (p = 0.023) and TGF-β (p = 0.030), and a notable upregulation of angiogenesis and proliferation markers VEGF (p = 0.031) and Ki-67 (p = 0.001). Molecular docking analyses revealed that CSSO-derived fatty acids showed binding affinities (-5.3 to -7.5 kcal/mol) with anti-inflammatory-related proteins (COX-2 and NLRP3) and (-3.1 to -6.1 kcal/mol) binding affinities with wound healing-related proteins (SIRT1 and GSK3β), suggesting a possible mechanistic basis underlying the wound healing potential of CSSO.
conclusionsTopical application of CSSO was associated with improved wound healing outcomes in rats, including enhanced wound closure and favourable histopathological and immunohistochemical changes. Further studies are needed to confirm these findings and clarify the mechanisms involved.
