Mechanistic insights into clary sage oils role in wound healing: targeting oxidative stress and inflammatory pathways.

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
Introduction: Clary sage essential oil (CSEO), extracted from Salvia sclarea, is known for its antioxidant and anti-inflammatory properties. While its general therapeutic benefits are recognized, its specific role in wound healing remains inadequately explored. This study investigates the effects of CSEO on oxidative stress, inflammatory cytokines, and tissue regeneration in a rat excision wound model. Methods: Rats were subjected to full-thickness excision wounds and divided into treatment, reference and control groups. The treatment group received topical application of CSEO, while reference and controls received standard drug and soft paraffin respectively. Wound healing was evaluated by measuring wound contraction and epithelialization. Biochemical assays assessed oxidative stress and inflammatory markers, while immunohistochemistry was used to analyse CD68 expression. Histological examinations evaluated granulation tissue, collagen deposition, angiogenesis, and inflammatory infiltration. Results: CSEO significantly enhanced wound contraction and epithelialization compared to controls. Biochemical analysis showed a reduction in oxidative stress markers. Immunohistochemical evaluation revealed decreased CD68 expression, along with significantly lower levels of pro-inflammatory cytokines TNF-α and IL-6. Histopathological findings demonstrated improved granulation tissue formation, increased collagen synthesis, enhanced angiogenesis, and reduced inflammatory cell presence in CSEO-treated wounds. Discussion: CSEO facilitates wound healing through its antioxidant and anti-inflammatory actions. The reduction in oxidative stress and inflammatory mediators, along with improved histological parameters, suggests that CSEO supports effective tissue repair. These findings highlight the therapeutic potential of CSEO as a natural wound-healing agent and support its further investigation in regenerative medicine.
