Ethnobotanical research in Cava de' Tirreni area, Southern Italy

Ethnobotanical Documentation of the Uses of Wild and Cultivated Plants in the Ansanto Valley (Avellino Province, Southern Italy)

With approximately 2800 species, the Campania region has the richest vascular flora in southern Italy and the highest number of medicinal species reported in the Italian folk traditions. The study area is inserted in a wide rural landscape, still retaining a high degree of naturalness and is studied for the first time from an ethnobotanical point of view. By analyzing local traditional uses of wild plants in the Ansanto Valley area, the present study aims to contribute to the implementation of ethnobotanical knowledge concerning southern Italy. To gather ethnobotanical knowledge related to the Ansanto Valley, 69 semi-structured interviews were carried out through a snowball sampling approach, starting from locals with experience in traditional plant uses (key informants). A number of 117 plant species (96 genera and 46 families) were documented for traditional use from a total of 928 reports, of which 544 were about medicinal plants. New use reports on the utilization of plants for medicinal (5) and veterinary applications (8) in the Campania region and the whole Italian territory were outlined from our investigations. Sedum cepaea is reported as a medicinal plant for the first time in Italy and in the whole Mediterranean basin.

Iconic Arable Weeds: The Significance of Corn Poppy (Papaver rhoeas), Cornflower (Centaurea cyanus), and Field Larkspur (Delphinium consolida) in Hungarian Ethnobotanical and Cultural Heritage

There are an increasing number of initiatives that recognize arable weed species as an important component of agricultural biodiversity. Such initiatives often focus on declining species that were once abundant and are still well known, but the ethnographic relevance of such species receives little recognition. We carried out an extensive literature review on the medicinal, ornamental, and cultural applications of three selected species, Papaver rhoeas, Centaurea cyanus, and Delphinium consolida, in the relevant Hungarian literature published between 1578 and 2021. We found a great diversity of medicinal usages. While P. rhoeas stands out with its sedative influence, D. consolida was mainly employed to stop bleeding, and C. cyanus was most frequently used to cure eye inflammation. The buds of P. rhoeas were sporadically eaten and its petals were used as a food dye. All species fulfilled ornamental purposes, either as garden plants or gathered in the wild for bouquets. They were essential elements of harvest festivals and religious festivities, particularly in Corpus Christi processions. P. rhoeas was also a part of several children's games. These wildflowers were regularly depicted in traditional Hungarian folk art. In poetry, P. rhoeas was used as a symbol of burning love or impermanence; C. cyanus was frequently associated with tenderness and faithfulness; while D. consolida regularly emerged as a nostalgic remembrance of the disappearing rural lifestyle. These plants were also used as patriotic symbols in illustrations for faithfulness, loyalty, or homesickness. Our results highlight the deep and prevalent embeddedness of the three iconic weed species studied in the folk culture of the Carpathian Basin. The ethnobotanical and cultural embeddedness of arable weed species should also be considered when efforts and instruments for the conservation of arable weed communities are designed.

Edible Flowers Used in Some Countries of the Mediterranean Basin: An Ethnobotanical Overview

Edible flowers are becoming an essential component of people's nutrition in the Mediterranean basin. In the last decades, many researchers also have focused their attention on the nutritional composition of the edible flowers, as well as their antioxidant and antimicrobial properties, including studies on their safety issues. Despite the growing interest in the use of flowers in human nutrition, the ethnobotanical literature is lacking coverage of some important issues, particularly those which concern the use of flowers in the folk tradition. Only recently, a review regarding the contribution of 32 edible flowers to the Mediterranean diet was published. The aim of the present review is to document the plant lore regarding the wild and cultivated edible flowers consumed in the Mediterranean basin. Based on the 112 studies reviewed, we documented 251 taxa as being used in the Mediterranean basin as edible flowers. The plant species belong to 45 families and 141 genera. Asteraceae (54 taxa) is the most frequently cited family. Sambucus nigra L. is the most cited species. This study can be the basis for future research on the supposed bioactivity and toxicity of wild and cultivated flowers.

Ethnomedicine survey on folk dermatology in Transylvania, Romania

From the beginning of recorded history through the present day, dermatologic disorders have been treated with ethnomedicine remedies. We present the ethnodermatologic practices in Transylvania, Romania. We conducted ethnomedicine surveys in 35 villages in Transylvania (2007-2019). The 650 people interviewed were questioned about the treatment of dermatologic disorders by drugs derived from plant, animal, human, or other origins. Collected data were compared to earlier records of the regions and other European countries, completed with relevant pharmacologic studies of some plants. A total of 180 drugs were documented for 45 skin problems, including 112 plants, 1 fungus, 19 animals, 5 humans, and 43 other materials used in 11 preparation forms. Among these, 144 drugs were mentioned in humans, 10 in veterinary medicines, and 26 included in both therapies with overlapping human/animal (eg, Petroselinum crispum) and specific uses (eg, Daphne mezereum, Scrophularia nodosa). Compared to data from other countries, the local use of 32 plants and various animals and minerals was described only in the study area. The present study demonstrates that ethnomedicine practices are a valuable source of knowledge for skin diseases and highlight the relevance of fieldwork in the selected regions of Transylvania.

Walking around the Autonomous Province of Trento (Italy): An Ethnobotanical Investigation

The Trentino-South Tyrol region is a special statute region of northeastern Italy. This territory is of particular interest for its morphology, flourishing vegetation, and history, having been a meeting area among different civilizations. Hence, Trentino is characterized by an ethnic plurality and a rich ethnobotanical knowledge, even if the available information is fragmentary, widely dispersed, and often guarded in oral popular culture. To fill this gap, in the present work 200 subjects were interviewed using an ethnobotanical survey. The resulting 817 citations referred to 64 native species, used either for human or animal health or for domestic purposes. As a second step, for each plant exploited for medicinal purposes, local importance was evaluated by calculating their relative frequency of citation. Moreover, the main traditional preparations were discussed. Among them, the most cited and exploited ones are Achillea millefolium, Arnica montana, Hypericum perforatum, Malva sylvestris, Pinus mugo, and Satureja montana, for which a deeper analysis has been performed. Lastly, the ethnobotanical knowledge of the plants growing in this territory will add a piece to the mosaic of traditional medicine in Italy and may lay the foundation for a nature-aided drug discovery process.

Ethnobotanical Review and Dataset Compiling on Wild and Cultivated Plants Traditionally Used as Medicinal Remedies in Italy

Over the centuries, wild plants have constituted the main food ingredients and traditional medicine in rural communities. In the last decades, thousands of ethnobotanical studies have been conducted, with the aim of documenting the traditional knowledge on wild and cultivated plants both for food and therapeutic purposes. In the present work, 75 published papers related to Italian ethnobotanical knowledge on wild and cultivated plants traditionally used for medical purposes were analyzed and data on 1117 different species organized in the first dataset to target medicinal applications only. For each plant species, the Italian region of use, plant organs, mode of preparation, specific pathological group of application, citation index, and use index were listed. The different therapeutic applications were subdivided into nine main pathological groups according to the targeted human apparatus. Overall, the cited species with highest number of uses were related to the treatment of the digestive system and skin-ears-eyes-hair diseases, followed by diseases of the genito-urinary and respiratory systems. The 13 most relevant species were identified on the basis of their citation and use indexes. The present review on Italian medicinal flora aims to provide valuable information on wild and cultivated species, which are potential sources of plant-based therapeutic remedies, to preserve and reevaluate endangered traditional folk knowledge.

Traditional Herbal Remedies Used for Managing Anxiety and Insomnia in Italy: An Ethnopharmacological Overview

Anxiety and insomnia are among the most common mental health disorders and are a major cause of disability around the world. Traditional herbal medicines are receiving significant attention in global health debates. Several Italian regions maintain rural traditions and are among the most extensively studied areas of Europe regarding medicinal plant uses. The present overview aims to highlight the use of wild and cultivated plants, specifically as sedatives and for insomnia treatment in Italy, and to collect, analyze, and summarize the available literature about their pharmacological activity as well as clinical and pre-clinical studies concerning the most cited plants. In total, 106 wild taxa are used in Italy for sedative purposes. The plant species belong to 76 genera and 32 families, of which the most cited are Asteraceae (24.2%) and Lamiaceae (21.1%). Leaves (29%) and flowers (27%) are the plant parts mostly used as infusion (70%) and decoction (25%). Out of 106 taxa documented, only the most cited are analyzed in this overview (A. arvensis L., C. nepeta L., C. monogyna Jacq., H. lupulus L., L. nobilis L., L. angustifolia Mill., M. sylvestris L., M. chamomilla L., M. officinalis L., O. basilicum L., P. rhoeas L., P. somniferum L., R. officinalis L., T. platyphyllus Scop., and V. officinalis L.). Among the fifteen species selected, only seven have been studied for their pharmacological activity as hypnotic-sedatives. Future pre-clinical and clinical studies are needed to better clarify the mechanism of action of bioactive compounds and confirm the potential of these alternative therapies.

An Ethnobotanical Study of Medicinal Plants in Mersin (Turkey)

This comprehensive ethnobotanical study carried out in Mersin province, which is located in the southern part of Anatolia, east of the Mediterranean Sea, compiles details on plants used in folk medicine and ethnopharmacological information obtained through face-to-face interviews. The aim was to collect and identify plants used for therapeutic purposes by local people and to record information on traditional herbal medicine. Plant specimens were collected in numerous excursions. Additionally, informant consensus factor and use value (UV) were calculated for information gathered. This study identifies 93 plant taxa belonging to 43 families and records their usage in folk medicine; 83 taxa are wild and the remaining 10 are cultivated. The most commonly used plants belong to Lamiaceae, representing 15.0% of the total, while the Rosaceae, Malvaceae, Hypericaceae, Asteraceae and Cupressaceae families each represented another 5.4%. As a result of this investigation, we determine 189 medicinal usages of 93 taxa. The UV values indicate that the most important medicine plants are Hypericum perforatum (0.80), Cedrus libani (0.78), Quercus coccifera (0.77), Arum dioscoridis (0.76) and Juniperus drupaceae (0.74). We observed that most of the drugs are prepared using the infusion method (27.6%). As a conclusion, the study finds that traditional folk medicine usage is still common, especially among the rural population of Mersin.

Wild Plants Used as Herbs and Spices in Italy: An Ethnobotanical Review

Wild edible plants are an essential component of people's diets in the Mediterranean basin. In Italy, ethnobotanical surveys have received increasing attention in the past two centuries, with some of these studies focusing on wild edible plants. In this regard, the literature in Italy lacks the coverage of some major issues focusing on plants used as herbs and spices. I searched national journals for articles on the use of wild food plants in Italy, published from 1963 to 2020. Aims of the present review were to document plant lore regarding wild herbs and spices in Italy, identify the wild plants most frequently used as spices, analyze the distribution of wild herbs and spices used at a national scale, and finally, to describe the most common phytochemical compounds present in wild plant species. Based on the 34 studies reviewed, I documented 78 wild taxa as being used in Italy as herbs or spices. The studies I included in this systematic review demonstrate that wild species used as herbs and spices enrich Italian folk cuisine and can represent an important resource for profitable, integrated local small-scale activities.

Cactus: Chemical, nutraceutical composition and potential bio-pharmacological properties

Cactus species are plants that grow in the arid and semiarid regions of the world. They have long fascinated the attention of the scientific community due to their unusual biology. Cactus species are used for a variety of purposes, such as food, fodder, ornamental, and as medicinal plants. In the last regard, they have been used in traditional medicine for eras by the ancient people to cure several diseases. Recent scientific investigations suggest that cactus materials may be used as a source of naturally-occurring products, such as mucilage, fiber, pigments, and antioxidants. For this reason, numerous species under this family are becoming endangered and extinct. This review provides an overview of the habitat, classification, phytochemistry, chemical constituents, extraction and isolation of bioactive compounds, nutritional and pharmacological potential with pre-clinical and clinical studies of different Cactus species. Furthermore, conservation strategies for the ornamental and endangered species have also been discussed.
