Immunomodulatory effect of Cannabis root extract on inflammatory cascades via endocannabinoid system regulation.

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
backgroundCannabis roots have been widely used in traditional medicine, with documented references in classical texts describing their use for the treatment of various inflammatory diseases and pain. Despite their longstanding ethnopharmacological significance, the bioactive compounds responsible for these effects and their underlying mechanisms remain unexplored. The present study was conducted to evaluate the unique anti-inflammatory mechanisms of Cannabis sativa root fractions, and moreover, to investigate its mechanism related with the endocannabinoid system (ECS).
methodsAntioxidant activities and phenol contents of various Cannabis root fractions were determined by chemical assays. The effects of cannabis root fractions on inflammatory markers and endocannabinoid receptor (CB1, CB2) levels were evaluated in LPS-stimulated RAW 264.7 cells. Intracellular 2-arachidonoylglycerol (2-AG) levels were measured using LC-MS/MS. The fraction with the highest potential was further investigated to elucidate its mechanism using endocannabinoid receptor antagonists.
resultsAmong the fractions, ethyl acetate fraction (CSREA) demonstrated the highest potential in both antioxidant and anti-inflammatory effects. However, its effect was not attributed to the inhibition of NF-κB signaling pathways. LC-MS/MS analysis showed that CSREA affected intracellular 2-AG levels, supporting its potential via the ECS. CSREA also effectively suppressed ERK phosphorylation, a critical inflammatory signaling pathway modulated by ECS. However, CSREA activity was reduced by co-treatment with a CB1 antagonist.
conclusionThis study demonstrates that CSREA suppresses inflammatory responses and restores cellular homeostasis primarily by regulating the endocannabinoid system. However, its exclusive use of an acute in vitro inflammation model represents a limitation, and the effects of CSREA in chronic and in vivo settings require further investigation.
