Leveraging crude extracts from European tree bark to combat oxidative stress, enhance wound healing, and inhibit pathogenic bacterial growth.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The growing interest in plant-based therapeutics has increased investigations into natural resources rich in bioactive compounds, such as tree bark. Despite historical use in traditional medicine, the therapeutic potential of European tree bark remains underexplored. This study evaluated the antioxidant, antimicrobial, and wound-healing properties of aqueous extracts from the bark of six European tree species, namely Alnus glutinosa, Fagus sylvatica, Betula pendula, Prunus padus, Quercus spp., and Pinus sylvestris. The bark extracts were analyzed for chemical composition, total phenolic content, and antioxidative properties using a DPPH assay and a ROS inhibition assay in human keratinocytes. Antimicrobial activity was tested against seven bacterial strains using a MIC assay, and the wound healing potential was evaluated using a scratch assay. All extracts enhanced wound closure and decreased ROS production in HaCaT cells, with alder and bird cherry bark extracts showing the strongest effects. The antimicrobial assay revealed potent activity against Gram-positive pathogens, with alder bark extract showing the greatest efficacy. The findings highlight the potential therapeutic application of European tree bark extracts in addressing oxidative stress, infections, and wound healing, validating traditional medicinal practices, and providing a sustainable approach for forestry byproducts in modern phytotherapy, potentially contributing to skin disorder treatments.
