Global food security and dietary diversity depend on identifying novel and sustainable food sources. Wild edible plants (WEPs) traditionally used in Mediterranean regions offer considerable potential due to their rich history of use. Here, ethnobotanical knowledge was systematically compiled for the fruits and cones of five taxa (Arbutus unedo, Prunus spinosa, Quercus spp., Pinus spp. and Rosa spp.), documenting alimentary uses, preparation and conservation methods across diverse food categories. Analysis of over 2800 traditional use reports identified 54 distinct alimentary uses from 16 categories, with raw consumption and sweet preserves being the most prevalent. Rosa spp. exhibited the highest diversity of uses (36), whereas the family Pinaceae showed the lowest (19). Statistically significant associations between individual fruits and specific food preparations were also observed, offering guidance for innovative product development. Information on processing methods that preserve nutritional components, along with documentation of potential harmful effects and the methods to mitigate them, was collected, providing essential guidance for developing safe and functional alimentary products. Together, traditional knowledge, regulatory adherence, and sustainable practices create new opportunities to develop innovative, safe, culturally grounded, and sustainable food products that enrich diets and preserve cultural and ecological heritage.

Medicinal and aromatic plants contain valuable natural compounds widely used in health, food, and cosmetics. This study compares the antioxidant capacities and phenolic compositions of tea and ethanol extracts from eight species naturally growing in Fethiye, Muğla, Türkiye. Antioxidant activity was assessed using the β-carotene bleaching method, 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS⁺), cupric reducing antioxidant capacity (CUPRAC), and metal chelating activity. Herbal teas generally showed stronger antioxidant activity than ethanol extracts. Rosemary tea had the highest activity (2.90 µg/mL), followed by lavender (11.30 µg/mL). In metal chelating, rosemary tea exhibited a half-maximal inhibitory concentration (IC₅₀) of 9.22 µg/mL, close to ethylenediaminetetraacetic acid (EDTA). Phenolic profiling showed rosemary tea contained 30.74 mg/g rosmarinic acid and 0.74 mg/g quercetin. These results support the traditional use of southwestern Türkiye’s medicinal plants and emphasize the antioxidant potential of herbal teas. Integrating ethnobotanical knowledge with phytochemical data provides a basis for functional food development, crop improvement, and conservation of local plant genetic resources. Unlike previous studies focusing on single species or limited solvent comparisons, this research simultaneously evaluates both herbal tea and ethanol extracts of eight locally grown medicinal plants, offering a unique perspective on their comparative antioxidant and phenolic diversity.

Surfactants are essential in cosmetic and food formulations but are still dominated by petrochemical-derived anionic systems associated with irritation, aquatic toxicity and sustainability concerns. Plant-derived saponins offer renewable, biodegradable alternatives, yet only a small subset of saponin-producing species has been developed into commercial ingredients. The genus Albizia is chemically diverse and widely used in traditional medicine, with several species empirically employed as cleansers. This review examines Albizia amara and related Albizia species as prospective sources of plant-derived surfactants for cosmetic and food applications. We summarise ethnobotanical and phytochemical data with emphasis on saponins, flavonoids and macrocyclic alkaloids, and collate the limited quantitative evidence for surface activity, focusing on foaming behaviour, surface tension reduction and shampoo-type formulations, where A. procera provides the main interfacial benchmark within the genus. Potential roles of A. amara-derived fractions in hair-care products and prospective food systems are discussed alongside current knowledge on toxicity, safety and regulatory constraints. Overall, A. amara emerges as a promising but under-characterised saponin source. Priority areas for future work include robust tensiometric characterisation, surfactant-focused extraction and fractionation, systematic formulation studies, and dedicated safety and sustainability assessments to enable evidence-based evaluation against established plant and synthetic surfactants.

An ethnobotanical survey in the northern mountainous region of Vietnam identified four Elsholtzia species, E. blanda, E. ciliata, E. communis, and E. penduliflora, growing naturally above 1500 m and traditionally used by local ethnic communities to treat skin-related ailments. This study investigates their essential oil possible chemotypes, antimicrobial properties, and potential mechanisms of action through molecular docking. Essential oils obtained by steam distillation were analyzed using GC–MS. E. blanda (yield 1.17%) was characterized by high levels of 1,8-cineole (29.0%) and camphor (17.0%). E. ciliata (1.02%) represented a possible limonene-dominant chemotype (71.0%). E. communis (1.91%) contained an exceptionally high proportion of rosefuran oxide (86.2%), whereas E. penduliflora (0.91%) exhibited a pronounced 1,8-cineole chemotype (92.1%). All essential oils showed antimicrobial activity against Staphylococcus aureus (MSSA and MRSA), Escherichia coli, and Candida albicans, with MIC values ranging from 0.4% to 3.2%. Except for E. ciliata against C. albicans, MBC/MIC and MFC/MIC ratios ≤ 4 indicated predominantly bactericidal or fungicidal effects. Molecular docking further identified nine of twenty-eight detected constituents as strong binders to microbial target proteins. These findings expand current knowledge on possible chemotypic diversity within the genus, particularly the discovery of a high-altitude limonene chemotype in E. ciliata and the identification of E. penduliflora as a rich natural source of 1,8-cineole. The convergence of chemical, biological, and in silico evidence supports the ethnomedicinal relevance of Elsholtzia species and highlights their potential as candidates for developing natural antimicrobial agents.

Globularia alypum L. (Plantaginaceae) is widespread in the Mediterranean region and traditionally used against diabetes, digestive disorders, infections, and skin problems. This review summarizes its botanical features, ethnobotanical uses, phytochemistry, pharmacological effects, and toxicological profile. Relevant studies published between 1991 and 2024 were retrieved from Web of Science, Scopus, PubMed, and other relevant databases using targeted keywords in English and French. Extracts of G. alypum have shown significant antidiabetic, antioxidant, anticancer, antibacterial, anti-inflammatory, anticoagulant, nephroprotective, and wound-healing activities in vitro and in vivo, which were largely attributed to its diverse secondary metabolites such as phenolics, flavonoids, and iridoids. Toxicological studies indicate generally low risk at tested doses. However, further research is needed to elucidate the molecular mechanisms underlying these activities, validate its efficacy through clinical trials, and evaluate long-term safety, thereby bridging traditional knowledge with modern pharmacological evidence.

Although younger generations are not always given a prominent role in ethnobotanical surveys, studying intergenerational knowledge transfer should still be a primary interest, in the context of traditions’ erosion, globalization, disinterest and plant blindness. Our study was designed to describe the situation of knowledge transfer and to find potential solutions to counteract erosion by involving the children. This ethnobotanical survey involved students from primary and secondary schools of Valle Imagna (Bergamo, Italy) through different meetings and structured questionnaires to record their traditional knowledge on medicinal plants. The children were then asked to become an active part of the project by interviewing their families. All data recorded were archived in a database for statistical analysis. Students (number = 112) reported 41 plant species, with 36% reporting at least 3 species each. Forty percent of their use reports were related to exotic species or purchased plant material. The most reported species were Matricaria chamomilla L. and Camellia sinensis (L.) Kuntze with common preparations such as infusions from commercial products. Parents (n = 96) reported 76 species and grandparents (n = 35) 52. Statistical analysis showed correlation between traditional knowledge and age/gender, with older generations and female gender correlated to deeper knowledge. Our results suggest deep erosion and a clear lack of intergenerational knowledge transfer. However, our project serves as evidence of the concrete role ethnobotany holds in safeguarding the remaining cultural heritage of a territory, fostering preservation from the outset with the participation of younger generations.

Wild edible plants contribute significantly to food security, environmental protection, cultural heritage preservation, economic diversification, and the development of communities. In this paper, we present an inaugural ethnobotanical investigation of the traditional knowledge on wild edible plant species from Makkah, Kingdom of Saudi Arabia. Ethnobotanical fieldwork was conducted in Makkah from January to February 2025. Ethnobotanical data pertaining to wild edible plants were collected from 102 informants through free listing, semi-structured interviews, field observations, and a survey of the market. The data were analyzed based on descriptive statistics, the relative frequency of citation, preference ranking, and priority ranking. Forty-one out of one hundred and eighty-four wild plants were gathered and recognized as wild edible plant species belonging to twenty-one families. Poaceae showed the greatest species diversity, comprising five plant species (12%). Phoenix dactylifera L. is the most common wild edible plant. Notably, 11 of the 41 wild edible plants identified in this study had never been reported in the Kingdom of Saudi Arabia before. Wild edible plants are currently threatened by several anthropogenic sources in the research region, including overgrazing, fuel wood collection, and the repeated use of multiple species. Therefore, to ensure sustainable future usage, wild food plants must be used carefully and should be the subject of targeted conservation efforts from all stakeholders. Full article

The transformation of Local Ecological Knowledge (LEK) among minority populations undergoing cultural and linguistic assimilation over time is poorly understood. Arbëreshë communities in Greece, who have preserved Albanian-derived traditions for centuries, offer a unique opportunity to examine how folk plant knowledge adapts over time. This study examines the linguistic labels and culinary uses of wild greens among Arbëreshë (or Arvanites), an ethno-linguistic minority traditionally speaking Arbërisht or Arvanitika, the Tosk dialect of Albanian, who have resided in the Argolis and Corinthia regions of the Peloponnese for several centuries. In 2025, fieldwork was conducted in four rural Arbëreshë villages in the Argolis and Corinthia regions of Greece, combining semi-structured interviews with 24 elderly participants, participant observation, and the collection and identification of botanical specimens. The contemporary dataset was compared with historical ethnobotanical records from the 1970s to assess temporal changes in the use of wild vegetables and folk plant nomenclature. Our results reveal that current Arbëreshë ethnobotanical heritage has undergone profound Hellenisation, with 62% of folk plant names of Greek origin, 14% Albanian, and 24% hybrid, reflecting strong linguistic and cultural assimilation over the past half-century. The traditional boiled green mix (lakra in Arbëreshë, chorta in Greek) remains central to the local cuisine, which is rooted in foraged plants, although its culinary applications have diversified. In total, 37 taxa of wild vegetables across 37 genera and 14 families were documented in 2025, compared with 21 taxa across 21 genera in the filtered 1970 dataset. Core families, such as Asteraceae and Brassicaceae, remained dominant, while new families, like Malvaceae and Portulacaceae, appeared, possibly indicating both ecological and culinary changes. These findings raise questions about whether the Arbëreshë wild vegetable heritage was strongly influenced by the surrounding Greek majority or primarily acquired after migration, potentially facilitated by intermarriages and shared Orthodox Christian affiliation. Overall, our study highlights a largely Hellenised Arbëreshë biocultural heritage and underscores the urgent need for national and regional stakeholders to recognise and celebrate the remaining minority’s linguistic and ethnobotanical diversity. The transformation of local ethnobotanical knowledge over the past fifty years appears influenced by ecological availability, socio-cultural dynamics, and changing taste preferences. Full article

This study documents the diversity, ethnobotany, and ethnolinguistic aspects of Passifloraceae species in Non Din Daeng District, Buri Ram Province, Thailand. Field surveys conducted from April 2024 to March 2025 recorded nine taxa across three genera, including two native species (Adenia heterophylla and A. viridiflora) newly reported for Buri Ram Province, and seven taxa (Passiflora ‘Soi Fah’, P. edulis f. flavicarpa, P. miniata, P. trifasciata, P. vesicaria, Turnera subulata, and T. ulmifolia) representing new provincial records. Native species were primarily associated with dry dipterocarp and mixed deciduous forests, whereas introduced taxa occurred mainly in cultivated or disturbed habitats, reflecting both ecological adaptability and human-mediated introduction. Ethnobotanical data revealed diverse uses including food, traditional medicine, ornamentals, beverages, and economic purposes with P. edulis f. flavicarpa and A. viridiflora having particularly high cultural and economic significance. Passiflora flower also holds cultural prominence, inspiring local and iconic textile motifs of Non Din Daeng. Vernacular names and terminology provide insights into local classification systems and cultural perceptions of these plants. Conservation assessments indicate potential threats to A. heterophylla from wild harvesting, whereas cultivated and naturalized Passiflora taxa are assessed as Least Concern. The results highlight the ecological, cultural, and economic value of Passifloraceae in Non Din Daeng District and emphasize the role of community knowledge in biodiversity conservation and sustainable management.

Medicinal plants have long been used for therapeutic purposes in the mountainous Hakkâri region of southeastern Türkiye. This study presents an integrated toxicological risk and therapeutic assessment of four ethnomedicinal species—Daphne mucronata Royle, Ferula communis L., Heracleum persicum Desf., and Tragopogon coloratus C.A.Mey—based on their flavonoid and phenolic composition, elemental content, and antioxidant capacity. To the best of our knowledge, this is the first study to integrate multiple analytical platforms—including HPLC, ICP-OES, AAS, UV-Vis spectrophotometry, and SEM/EDX—to assess both the therapeutic potential and toxicological risks of these ethnomedicinal species. Although a complete phytochemical profile was not the objective of this study, selected phenolic compounds and antioxidant capacity were evaluated to highlight bioactivity, while heavy metal-based risk assessment was prioritized given public health relevance. Antioxidant capacity was measured using DPPH, ABTS, and CUPRAC assays, while human health risks were quantified through Estimated Daily Consumption (EDC), Target Hazard Quotient (THQ), Hazard Index (HI), and Carcinogenic Risk (CR). The results revealed a dual nature: Heracleum persicum exhibited the strongest antioxidant activity, correlating with its high phenolic content, while Daphne mucronata showed elevated toxic metals exceeding WHO/FAO thresholds. Overall, the findings emphasize the importance of combining ethnobotanical knowledge with robust analytical tools for safe medicinal plant usage. Full article
