Information on traditional uses of 95 botanical taxa was collected; more than half of which are used to treat a wide range of diseases, ranging from pains of different origins, to skin problems, and diseases of the respiratory system. For each medicinal species, data were collected including the vernacular names, preparation, plant part, and therapeutic use. Twenty-four out of the 57 medicinal plants listed have a therapeutic use not previously reported in Campania and neighbouring regions. Plant uses by Montecorvino inhabitants are compared with those described in medical and botanical literature by Campanian authors from the last three centuries. © 2006 Elsevier Ireland Ltd.

Introduction The study of traditional uses of plants and their products in the Mediterranean region has been progressively increasing during the past few years, and has enabled the collection of a significant body of knowledge (Abu-Irmaileh and Afifi, 2003; Ali-Shtayeh et al., 2000; Agelet and Valles, 2001; Camejo-Rodrigues et al., 2003; El-Hilaly et al., 2003; Everest and Ozturk, 2005; Hanlidou et al., 2004; Heinrich et al., 2005; Leporatti and Ivancheva, 2003; Pieroni and Quave, 2005, 2006; Said et al., 2002; Skoula et al., 2003; Tuzlaci and Aymaz, 2001; and references therein). In Italy, recent ethnobotanical research has been mainly focused on Central-South Italy, taking into special account traditional plant knowledge (TPK) of small ethnic groups and isolated communities (Guarrera, 2003, 2005; Guarrera et al., 2005; Leporatti and Corradi, 2001; Palmese et al., 2001; Pieroni et al., 2002, 2004, 2005). Compared to neighbouring regions, particularly Latium and Basilicata, Campania has been poorly studied from an ethnopharmacological point of view, the only studies dealing with this topic being confined to a few locations, e.g., Rocca- ∗ Corresponding author.

No studies have been conducted so far in the inland territory of Campania, which includes Avellino and Benevento provinces, and represent more than one third of the regional territory. Inland Campania, like many other interior territories of Central and South Italy, is mainly mountainous, with a small population, relatively small settlements, and numerous well preserved and protected natural areas that are only partially studied for their floristic and vegetational characteristics. The municipality of Montecorvino Rovella (MR) is located at the foot of Mount Telegrafo (Fig. 1), which belongs to the Monti Picentini range, one of the southern spurs of Appennini Campani. The district extends to the coast, embracing very different vegetation belts, ranging from beach to chestnut groves. The MR can be considered one of the corridors that connects the coast to inland Campania, and is situated at the boundary of several districts: the Vesuvian area to the north, the Cilentanean area to the south, the Sorrentinean area to the east, and the Irpinian area to the west. It is well connected to the north, east, west, and south by major roads that have been used since prehistoric times by the diverse ethnic groups inhabiting Campania and neighbouring regions. Therefore, the MR area is expected to have been heavily influenced by adjoining areas. 296 A. De Natale, A. Pollio / Journal of Ethnopharmacology 109 (2007) 295–303 Fig. 1. Location of the area studied. After 553 BC, following the battle that destroyed Picentia, the Romans forced the survivors to spread out and settle in small communities. Thus, MR was originally constituted as a few clusters of houses, most of which expanded until they became large villages (e.g., Occiano, Ferrari, Gauro, Macchia, Marangi, Martorano, Molenadi, Nuvola, S. Martino, Votraci, Cornea, and Bellizzi). In the following centuries the Barbarians, such as Goths, Longobards, Saracens, and Normans invaded the area (Serfilippo, 1856) and lead to marked changes in the language, habits, and civilisation. The aim of this paper is to highlight the eventual occurrence of an ethnobotanical koinè extending from inland Campania to the coastal areas. The traditional plant knowledge (TPK) of the MR community has been compared with that reported for the municipalities of Ascea-Monte Vesole and Monti Lattari Peninsula (De Feo et al., 1992; De Feo and Senatore, 1993; Scherrer et al., 2004), located to the west and south-east of MR, respectively, and closely related to coastal Campania. Due to the scarcity of recent studies dealing with plant uses in inland Campania, the MR data were compared to ethnobotanical information gathered for this geographical area from historical sources dating back to two centuries. 2. Methodology 2.1. Study area The MR area is characterised by a very complex orography, hence many different plant communities are present. On the top of mountains there are rocky phytocenoses rich in Apennineendemics (e.g., Campanula fragilis Cyr. s.l., and Cardamine chelidonia L.), orophytes and mountain-Mediterranean species (e.g., Arabis collina Ten and Biscutella laevigata L.), some of which are very rare in southern Italy. Grazing lands belong to the typical Apennine Brometea (with Bromus erectus Huds., Anthyllis montana L., and Lotus corniculatus L.), whereas woody vegetation is mainly represented by chestnut groves, which are very well preserved, especially in the upper stands (with Lilium martagon L., Neottia nidus-avis (L.) Rich., and Epipactis helleborine (L.) Crantz). During the last few years, land use development produced strong changes in lower mountain areas. In those stands the Mediterranean maquis was substituted by crops, and more recently also by expanding urban and industrial areas. Land use changes also affected the areas at elevations from 750 to 900 m, where chestnut plantations were replaced by hazelnut. Little or no transformation has taken place in the highest areas. In the mountain areas there is no dry period, even during summer, whereas at lower elevations the Mediterranean climatic pattern is easily recognisable, with a dry summer from June to August. Rainfall is mainly restricted to late spring and autumn. The mean annual temperature ranges between 12 and 16 ◦ C in the lower areas, and between 6 and 12 ◦ C in the upper areas. The most important economic resource of MR is hazelnut, and to a minor extent olive cultivation. Some industrial areas are also present, though they are not considered of primary importance. 2.2. Methods Field work was conducted from April to October 2000. The information was gathered by ethnobotanical interviews, limited to people involved in agriculture and living outside major MR villages, in very small rural settlements, often with no more than two or three houses where small families of peasants live. Their economic way of life does not rely entirely on agriculture. Small landholdings, comprising the majority of the land adjacent to the settlements, are used for subsistence farming, and all our informants resided there. Preliminary investigations suggested that people living in larger MR villages and working in the secondary or tertiary sector did not retain knowledge about the local flora and its uses. Fifty-six participants were initially selected; most were women (60% female and 40% male), aged between 50 and 85 (average age 65). Open informal interviews were used to collected information. Twenty-five people were chosen from the selected participants on the basis of their ability to identify species in the field and to retain traditional knowledge of plant uses. Only the plants indicated by at least two informants were taken into account. Generally, plants were collected with the informants, who were asked to indicate their vernacular names, the part of the plant and its uses, and the preparation procedure. Plant samples were identified in the field, except for dubious cases, which were brought back to the laboratory and identified according to Pignatti (1982) and Tutin et al. (1964–1980, 1993). The floristic list is ordered alphabetically. Nomenclature is according to Tutin et al. (1964–1980, 1993), though in some cases the Med-Checklist (Greuter et al., 1984, 1986, 1989) was used. Voucher specimens of wild plants reported by informants in the study area were prepared and deposited in the Herbarium of the Department of Arboricoltura, Botanica e Patologia Vegetale dell’Università di Napoli “Federico II” (PORUN). 3. Results and discussion Ethnobotanical investigation in the municipality of MR has revealed that 95 species, out of a total of about 400 species A. De Natale, A. Pollio / Journal of Ethnopharmacology 109 (2007) 295–303 Fig. 2. Percentage spectrum of the ethnobotanical uses of the entities in MR. identified in this territory (De Natale, unpublished results), are used for different purposes related to local traditions (Fig. 2). The etnobotanicity index (Portères, 1970) applied to useful plants is 23.75, which indicates a good level of TPK, comparable to that of other Mediterranean areas. Similar index values were found in Spain (Agelet and Valles, 2001; Martinez, 1993) and in Tunisia (Boukef, 1986). Table 1 lists the medicinal plants (57 species) of MR and their related applications. More than half (58%) of phytoremedies described were quoted by no more than four informants, which represent less than 20% of the total number of informants. This low consensus distribution suggests that TPK are declining in this territory, and could explain the reduced number of plants used in MC folk therapy. Medicinal species listed belong mainly to Rosaceae (10 species), followed by Fabaceae and Asteraceae, both with 6 species, Poaceae (5), Fagaceae (4) and Lamiaceae (4). All these families are largely represented in Mediterranean Flora, and medicinal uses of their members have been already reported for Turkey (Everest and Ozturk, 2005), Bulgary (Leporatti and Ivancheva, 2003), Greece (Hanlidou et al., 2004), and Spain (Raja et al., 1997). Phytogeographical attributes of the species used in MC were derived from Flora d’Italia (Pignatti, 1982). Mediterranean species are well represented (21%); most of them are Stenomediterranean (8.8%) or Mountain-Mediterranean (14%). Euro-Asiatic species are also considerably abundant (19%) and are primarily found in wooded areas. Widely distributed species represent about 44% of the total. As already observed in many floristic researches related to the Campania district, this group has shown a remarkable increase during recent years (De Natale, 2003; La Valva and De Natale, 1993–1994). Most of these species are cosmopolitan (42%), mainly weeds, whereas the others are adventitious, typical of anthropic and urban areas. The relative abundance of the former group points out the importance of agricultural activity in these areas, as cultivated fields are usually invaded by species that are widely distributed all over the world (Ricciardi et al., 2004). In MR folk therapy the most frequently used plant organs are leaves (31 species) and the entire aerial part of the plant; flowers and fruits are often used, whereas the medicinal use of roots ad bulbs is more restricted (Table 2a). The majority of species provided one or few medicinal uses; however, Echium italicum L. is used to treat five different diseases, and Lamium album L., Sambucus nigra L., and Hedera helix L. subsp. helix are used for several different ailments. Internal and external uses of 297 plants are equally distributed. The most reported uses are related to the treatment of pains (ranging from toothache to rheumatic and arthritic complaints), and ailments of the respiratory system, including remedies for cough, which represent the ailments most frequently cited by MR inhabitants (Table 2b). With reference to the procedure of preparation, plant potions (infusion and decoction) represent by far the most common way to administer medicinal plants; however, external applications of fresh plants are also frequently used (Table 2c). The use of preparations containing more than two plants species is specifically designed for a few apparently not related ailments. Plants are generally used in the therapy of existing ailments, the prophylactic use being restricted only to Eryngium amethystinum L., whose flowers were previously eaten to prevent malaria. Medicinal plant uses recorded in MR were compared with the available ethnobotanical literature of Campania (Antonone et al., 1988; De Feo et al., 1992; De Feo and Senatore, 1993; Scherrer et al., 2004), neighbouring regions with a special emphasis on Latium and Lucania (Guarrera, 2003, 2005; Leporatti and Corradi, 2001; Palmese et al., 2001; Pieroni and Quave, 2005; Pieroni et al., 2002; Pieroni et al., 2004), South Italy (Barbagallo et al., 1979; Catanzaro, 1970; Leporatti and Pavesi, 1989), and the standard Italian Officinal Flora (Gastaldo, 1987). In general, the phytotherapeutical plant use in MR is typical to all folk medicine, such as the use of the herbs individually or in potions, and the high number of plants administered to relieve pains (Adams and Garcia, 2006; Bueno et al., 2005; Schlege et al., 2000; Uniyal et al., 2006). On the other hand, by comparing the plants used in MR with those reported for neighbouring areas, it appears that there are many (24 of the 57 medicinal plants listed) uses that are not present in other locations, and that frequently, there are changes in the way the plants are administered. However, many of the peculiar medicinal uses documented in MR are quoted by the Italian Officinal Flora (Gastaldo, 1987). Moreover, for some of these species namely Agrimonia eupatoria L., Fumaria officinalis L., Lamium album L., and Symphytum officinalis L., similar uses have been quoted in other countries, mainly in the Eastern Mediterranean region (Hanlidou et al., 2004; Everest and Ozturk, 2005; Leporatti and Ivancheva, 2003). Probably, some of the unrecorded species were regarded in the past by different communities as medicinal herbs, but their uses have been abandoned. This is the case of Atropa bella-donna L. and Solanum nigrum L. subsp. nigrum, both toxic and responsible of severe poisoning (Aliotta, 1987). Their persistence in MR TPK could be considered as a relic of ancient traditions that are still alive in other Mediterranean communities, as reported by Dafni and Yaniv (1994) for Israel. For all the other unreported species, there is scarce available information, although some of these plants have been studied for their chemical and pharmacological properties, and the results could validate the folk therapeutic uses reported by MC informants. This is the case of Plantago afra L. seeds, whose utilisation has received clinical validation (WHO, 1999), and Cyperus rotundus L., that contains constituents with anti-inflammatory and analgesic properties (Gupta et al., 1971). Noteworthy is the therapeutical use of several cosmopolitan weeds, like Amaranthus retroflexus L., Chenopodium album L., 298 Table 1 Medicinal plants used in the phytoterapy of the MR Frequencya Local names Part(s) used Uses in the local popular medicine Preparation Adiantum capillus-veneris L.

Cronq., which are also administered altogether for external applications used to alleviate arthritic pains. The use in the treatment of arthritis is also reported for the latter species (Gastaldo, 1987). The weedy Chenopodium album could be used in the same way as Chenopodium vulvaria, which has been sometimes employed as an antirheumatic (Gastaldo, 1987). The medicinal use of Amaranthus retroflexus, which has no related species used in folk medicine in Italy, could be an extension of the more usual incorporation of new species with habit and distribution similar to old species in the TPK. The role of weeds in folk therapy is probably still not well evaluated. According to Stepp (2004), disturbed habitats are often preferred to forests by indigenous people for collecting medicinal plants, which are frequently weeds. Another possible explanation is that weeds are generally annual, and in their short-life span they accumulate a higher amounts of bioactive compounds (Stepp and Moerman, 2001). Eryngium amethystinum L. and Veronica cymbalaria Bodard are additional medicinal plants specific to MR, and administered against malaria. Although no reports are available on the phyto-therapeutic uses of Eryngium amethystinum, other Eryngium species from different geographical areas have been used to treat malaria (Cardozo et al., 2004). On the other hand, there is no evidence of the anti-malarial properties of Veronica cymbalaria. It cannot be ruled out that this species is commonly confused with the similar Cymbalaria muralis Gaertn., B. Mey. et Scherb, distributed all over MR and well known by its inhabitants as a remedy against malaria. Interesting is the use of Digitalis micrantha Roth as a replacement of Digitalis purpurea L. Digitalis micrantha is common in wooded areas of central and south Italy. At the beginning of the 19th century its medicinal use was suggested by the Campanian physician Stellati (1813), who stated that the plant had the same pharmacological properties, but limited side effects, compared to Digitalis purpurea. No recent studies have been carried out on Digitalis micrantha, and the pharmacological effects and chemical constituents of this species remain unknown. The same is true for the properties of Coronilla emerus L., also claimed to be effective as a cardiotonic, as reported by Usher (1974). Since Neolithic times (De La Genière, 1968) MC was in the commercial trade, and coastal and inland Campania were interconnected. Although this peculiar geographical posi- tion, the TK of this municipality seems to be prevalently local, and the suggestion of an ethnobotanical koinè including the territory lying between the Picentini Mountains and the Campanian coast is not supported by the present study. On the other hand, the hypothesis that the phytoterapeutical knowledge of Montecorvino’s community has more similarities with that of adjacent Apenninic territories remains unexplored: presently, studies dealing with the TK of the numerous mountain communities located in the Picentini district are completely absent. We have also taken into account several manuscripts written by physicians and naturalists in the 18th and 19th century describing the flora and, to a minor extent, the ethnobotany of several territories of inland Campania, although not specifically devoted to the Picentini district (Pasquale and Avellino, 1841; Pasquale and Pasquale, 1892; Petagna, 1796; Tenore, 1823, 1827). Only three of the species used in MR (Hedera helix L. subsp. helix, Hypericum perforatum L., and Matricaria recutita L.) are described in the historical literature, but it should be stressed that these species are used in the same way all over Italy (Gastaldo, 1987). In some other few cases (Agrimonia eupatoria L., Anagallis arvensis L. subsp. arvensis, Artemisia arborescens L., Ficus carica L., and Sambucus nigra L.), there was a limited correlation between folk therapeutic uses of MR and the selected literature, whereas no similarity was found for the other medicinal plants of MR territory. Since the reduced rate of shared TK of MC with neighbouring Companion territories has probably a cultural explanation, a combined anthropological and ethnobotanical field research is necessary to have a more detailed picture of the folk plant uses in this geographical area. As in many other countries also outside the Mediterranean basin, the dissemination of phytotherapeutical knowledge is prevalently matrilineal (Pereira, 1995–1996; Pokhrel et al., 2003; Martindale and Jurakic, 2004). Women administer plant remedies and transfer knowledge about the healing system from generation to generation. They generally have a sedentary life style, in contrast to men, who have much more opportunity for travel, meeting people, and exchanging information. Thus, cultural isolation may also occur in nonsegregated communities. The results of this first contribution on medicinal plant uses in inland Campania have indicated that this area could retain 302 A. De Natale, A. Pollio / Journal of Ethnopharmacology 109 (2007) 295–303 peculiar TPK, which surely deserves further research. As in many other Mediterranean areas, this is a very urgent task. Inland Campania is not an isolated territory: modern life styles have been fully accepted by the population and traditional culture is now limited to a very limited number of elderly people in the rural areas.
