Studies on pharmaceutical ethnobotany in the region of Pallars (Pyrenees, Catalonia, Iberian Peninsula). Part I. General results and new or very rare medicinal plants

An ethnobotanical survey was carried out in the region called Pallars--constituted by two districts, Pallars Sobirà and Pallars Jussà--situated in the Central Pyrenees, in North West Catalonia (Iberian Peninsula), with an approximate area of 2530 km(2) and a population of 19000. We obtained data on 437 plant species used for health care through interviews with 264 people. We detected 867 unreported or uncommon uses corresponding to 272 plant species, 52 of which had never or very rarely been cited as medicinal. To present the most important findings concerning the ethnopharmacology of the area studied, this first part includes the general results and the new or very scarcely reported medicinal vascular plants. Further papers will deal with unreported or very uncommon uses for known medicinal plant species and with medicinal non-vascular plants.     

Studies on pharmaceutical ethnobotany in the region of Pallars (Pyrenees,Catalonia, Iberian Peninsula). Part II. New or very rare uses of previously known medicinal plants

An ethnobotanical survey was carried out in the region called Pallars--consisting of two districts, Pallars Sobirà and Pallars Jussà--, situated in the Central Pyrenees, in North West Catalonia (Iberian Peninsula), with an approximate area of 2530 km(2) and a population of 19,000. Through interviews with 264 people, we obtained data on 437 plant species used for health care. We detected 867 unreported or uncommon uses corresponding to 272 plant species, 52 of which had never or very rarely been cited as medicinal. This is the second paper of a series intended to present the most important findings concerning the ethnopharmacology of the area studied; it includes unreported or very uncommon uses of known medicinal plant species. A previous paper reported the general results and the new or very scarcely reported medicinal vascular plants, and a further one will deal with medicinal non vascular plants.     

Studies on pharmaceutical ethnobotany in the region of Pallars (Pyrenees,Catalonia, Iberian Peninsula). Part III. Medicinal uses of non-vascular plants

An ethnobotanical survey was carried out in the region called Pallars--constituted by two districts, Pallars Sobirà and Pallars Jussà--, situated in the Central Pyrenees, in North West Catalonia (Iberian Peninsula), with an approximate area of 2530 km(2) and a population of 19000. Through interviews with 264 people, we obtained data on 437 plant species used for health care. We detected 867 unreported or uncommon uses corresponding to 272 plant species, 52 of which had never or very rarely been cited as medicinal. This is the third paper of a series intended to present the most important findings concerning the ethnopharmacology of the area studied; it includes information on 18 pharmaceutical uses of 16 non-vascular plant species (two algae, eight fungi, five lichens and one moss). Two previous papers reported the general results and the new or very scarcely reported medicinal vascular plants, and the unreported or very uncommon uses of already known medicinal plants.     

New contribution to the ethnopharmacological study of the Canary Islands

We present in this paper a report of 155 species used for medicinal purpose in the Canary Islands. These species have been compiled in 13 tables in accordance with their main medicinal use, indicating also other possible popular uses. We have made a short inventory of the rates of the most important medicinal applications. This new compilation shows once more the traditional use of the phytotherapeutic resources by the Canary population and also the wide possibilities of the phytochemical and pharmacological investigations of the Canary Islands Flora.     

Dittany of Crete: A botanical and ethnopharmacological review

Origanum dictamnus (Lamiaceae family), an endemic plant of the Greek island of Crete, is widely used as a traditional medicine since antiquity, all over Europe. The aim of the present review is to present comprehensive information of the plant's botanical taxonomy and morphology, as well as of the chemical constituents, biological and pharmacological research on O. dictamnus, which will be presented and critically evaluated. The paper also highlights particularly interesting aspects and common medicinal uses not previously described in the specific ethnobotanical literature. An increasing number of chemical and pharmacological studies have been reported recently, some of which strongly support its traditional medicinal uses against various illnesses such as sore throat, cough and gastric ulcer. A variety of compounds, including flavonoids, lipids and terpenoids (mainly carvacrol and thymol) have been identified from the plant. Current studies have showed that the extracts, the essential oil, as well as their active principles possess several pharmacological properties, like antimicrobial, antioxidant and anti-ulcer ones. The recent scientific data and the rich historical evidence of its medicinal uses could support further research as well as its use as a safe herbal medicinal product.     

Various uses of the castor oil plant (Ricinus communis L.) a review

The ancient and modern medicinal uses of the castor bean plant, Ricinus communis L. (Euphorbiaceae), in about fifty countries worldwide, has been surveyed. The different medicinal uses are grouped separately in relation to their pharmacological action, whether real or presumed, within the various medical specialities. The results show an extensive use of this plant throughout the world and the authors suggest that further research should be carried out to determine the active principles present in the various parts of the plant.     

Studies on pharmaceutical ethnobotany in the high river Ter valley (Pyrenees, Catalonia, Iberian Peninsula)

An ethnobotanical study has been carried out in the high river Ter valley (Catalonia, Iberian Peninsula) a small area located in the eastern Pyrenees, with 294 km(2) and 4526 inhabitants. Through 42 interviews with 60 informants of a mean age of 71.1, 220 species belonging to 71 botanical families were reported, 90.6% of which were used in human medicine and 7.8% in veterinary therapy. The present paper is focused on human medicinal plant uses. One fungal and four vascular plant species have not, or have very rarely been cited as medicinal, and for other taxa some very scarcely reported medicinal uses have been recorded (110 uses concerning 78 species).     

Pharmacopoeia in a shamanistic society: the Izoceño-Guaraní (Bolivian Chaco)

We present the results of an ethnopharmacological research within a Bolivian lowland ethnic group from the dry Chaco, the izoce?o-guaraní. Izoce?o-guaraní people belong to the extended Chiriguano group. They are actually organised in independent communities, settled down in south-east Bolivia. Struggling very soon for their rights, landowners of their territory, izoce?o-guaraní appear to be well organised and maintain a still vivid culture. Medicine is in the hands of Paye who are recognised as specialists in their own group. Ethnopharmacological research leads us to collect approximately over 306 species, 189 of them having medicinal uses. We present here an overview of the izoce?o-guaraní ethnomedicine and pharmacopoeia, based on vegetal and animal products.     

A survey of traditional medicinal plants from the Callejón de Huaylas,Department of Ancash,Perú

The medicinal uses of local flora from the Callejón de Huaylas, Department of Ancash, northeastern Perú, are reported. This geographical area has an old tradition of herbal healing. A total of 33 species have been documented through interactions with village elders, traditional doctors and herbalists. Of the 33 medicinal plant species surveyed in the Callejón de Huaylas, six have not been previously reported, seven have received only minor phytochemical coverage in the literature, and the medicinal uses of seven other plants have not been corroborated with traditional medicinal reports from around the world. The traditional medicinal uses of six medicinal plants have been corroborated with previously published reports but their biological activities have yet to be confirmed in the laboratory. The medicinal uses of four other plants have been corroborated with previously published reports and their biological activities have been confirmed in the laboratory. The purported medicinal use of three plant species could not be confirmed in the laboratory.

In this region, two surviving ethnic groups, the Saraguros and the Shuars, and the descendants of a now extinct culture, the Paltas, have been identified. The present study reports a total of 275 plant species, having 68 different therapeutical uses.     

Ethnobotanical study in the Madonie Regional Park (Central Sicily,Italy)—Medicinal use of wild shrub and herbaceous plant species

Ethnopharmacological relevance

This paper illustrates the results of an ethnobotanical study carried out in the Madonie Regional Park (Central Sicily, Italy). It specifies the medicinal uses of plants in the study area and contains the results of a quantitative analysis carried out for the first time in an area noted for its high degree of biodiversity. It also introduces 28 species not previously accounted for in the area of study for their medicinal uses, highlighting Silene flos-cuculi L. Greuter & Burdet, little known as medicinal in the Mediterranean area.

Aim of the study

To understand to what extent current knowledge on medicinal-use plants is still an element of the culture within the elderly population of the Madonie Regional Park.

Methodology

The information was obtained using a semi-structured interview format performed on 150 informants over the age of 60 who were considered experts in plants and rural traditions. The taxa were identified and the results were analysed also using a range of quantitative ethnobotanical indices.

Results

A census was made of 174 wild plant species, 100 of which with medicinal and veterinary uses, belonging to 49 botanical families. Of the 170 endemic species found in the Madonie Regional Park, only 2 species were cited in this study for medicinal purposes. Most of the species were used against dermatological diseases, general health and metabolic disorders. The leaves were the most-used parts of the plant and the most common preparation methods were decoction and infusion. The level of knowledge on medicinal uses of the plants was not found to be high within the elderly population, demonstrating an ongoing process of cultural erosion.

Conclusions

Only very few medicinal uses are widely known by all the informants and, on many occasions, a specific medicinal use was cited by only very few people. Further study is required in order to find out to what extent knowledge on the medicinal use of plants is still present in the younger generations in this area of Sicily, and what methods might be adopted in order to halt this gradual loss in knowledge.     

Studies on pharmaceutical ethnobotany in the region of Turkmen Sahra, north of Iran (Part 1): general results

This paper is the result of ethnobotanical survey on the Turkmens of Golestan and Khorasan Province (Iran) conducted from June 2002 to the end of 2003. Turkmens are traditionally an isolated ethnic group residing in northern parts of Iran. We studied the folk herbal medicine among Turkmens of Iran. Totally, 136 species from 51 families were documented from which 120 species used as medicinal and 84 species mentioned by three or more informants. Information about plant uses is all summarized in Table 1. Some interesting and endemic species have been reported for medicinal uses, also some new uses for common species were documented. Some of these species are good targets for further analysis.     

Ethnobotany of the Alt Empordà region (Catalonia,Iberian Peninsula): Plants used in human traditional medicine

Ethnopharmacological relevance

This paper provides significant ethnobotanical information on pharmaceutical plant uses from a tourist and industrialised region, where some degree of acculturation exists, so that there is urgency in recording such data.

Aim of the study

To collect, analyze and evaluate the ethnobotanical knowledge about medicinal plants in a north-eastern Iberian region (Alt Empordà, 1358 km², 129,160 inhabitants).

Methodology

We performed 101 semi-structured interviews with 178 informants (mean age 69; 71% women, 29% men), identified the plant taxa reported and analyzed the results, comparing them with those from other territories.

Results

The informants reported data on 518 species. Of these, 335, belonging to 80 botanical families, were claimed as medicinal. This work is focused on human medicinal plant uses, which represent 98% of the pharmaceutical uses (3581 out of 3643 use reports). Around 800 medicinal uses, concerning 200 species, have not, or have very rarely been cited as medicinal; of these, 32 uses of 30 species have been reported by three or more independent informants.

Conclusions

The folk knowledge about medicinal plant use is still alive in the studied region, and a number of scarcely reported plant uses has been detected, some of them with promising phytotherapeutical applications.

A search for natural bioactive compounds in Bolivia through a multidisciplinary approach. Part V. Evaluation of the antimalarial activity of plants used by the Tacana Indians

One hundred and twenty-five extracts of 122 different plant species traditionally used by the Tacana, a native community living in lowland forest at the base of the last foothills of the Cordillera Oriental of the Bolivian Andes, were screened for antimalarial activity in vitro on Plasmodium falciparum chloroquine resistant (D2) and sensitive strains (F32), and were evaluated in vivo on rodent malaria Plasmodium berghei. Five ethanolic stembark extracts showed marked activity either in vitro or in vivo, and only one of them, Bowdichia virgilioides being traditionally used against malaria, was active in vitro (IC50=1 microg/ml on both strains) and in vivo (51% at 100 mg/kg). Other active extracts were from Caesalpinia pluviosa bark displaying activity in vitro against chloroquine resistant strain (IC50 8.3 microg/ml), traditionally used against dysentery; two Lauraceae bark extracts, Nectandra aff. hihua and Licaria canella respectively used for construction purposes and against stomach ache, both displaying activity in vitro against P. falciparum sensible and resistant strains (IC50 around 4 microg/ml); finally, the bark of a strongly aromatic Burseraceae, Protium glabrescens exuding an anti-inflammatory and analgesic resin, was active in vivo only (61% at 100 mg/kg). Results are discussed in relation with Tacana traditional medicine.     

Preliminary comparative analysis of medicinal plants used in the traditional medicine of Bulgaria and Italy

Despite their geographical, historical and cultural differences, Bulgaria and Italy share a surprisingly similar patrimony as regards the popular uses of medicinal plants. The extensive knowledge acquired over the centuries by people living in these countries and engaged in agriculture, derives from continuous contact with natural resources. This paper compares approximately 250 medicinal plants present in both countries and used in popular medicine. From this comparison it emerges that knowledge of medicinal plants and their uses are well founded. In fact, more than 80% of the plants are employed in identical or similar kinds of ailments, their preparation also showing marked similarities. The remaining 20% have very different uses, several of these being particularly noteworthy. The role played by edible plants, moreover, is important, about 30% being employed as medicine.     

Some unique ethnomedicinal uses of plants used by the Korku tribe of Amravati district of Maharashtra, India

The present ethnobotanical study was carried out among the ethnic groups (Korku tribe) in the Chikhaldara, Achalpur and parts of Morshi in Amravati district of Maharashtra, India. A field survey of the study area was carried out during 2000-2004 to document the medicinal utility of plants occurring in this area by Korku tribe. Traditional uses of 66 plant species belonging to 40 families are described under this study. The documented ethnomedicinal plants were mostly used to cure skin disorders, diarrhea, jaundice, tuberculosis, stroke, migraine, menstrual problems, fertility problems, urinary problems, piles, wounds and poison bites. The medicinal plants used by the Korku tribe are arranged alphabetically followed by family name, herbarium number, local name, parts used, mode of preparation and medicinal uses.

Is the use-impact on native caatinga species in Brazil reduced by the high species richness of medicinal plants?

A study of the diversity of uses of medicinal plants and the traditional knowledge associated with the caatinga vegetation was undertaken in the semi-arid region of Pernambuco State, NE Brazil. We tested the utilitarian redundancy model (as an analogy to the ecological redundancy hypothesis) in evaluating the implications of the use of medicinal plants by rural communities to examine whether the presence of numerous species with analogous functions (identical therapeutic applications, for example) would reduce the use-impact on native species in the neighboring caatinga vegetation. Various techniques were used to collect information concerning medicinal plants and their applications from 19 residents considered "local specialists". The vegetation was sampled to determine the abundance of woody plants. Approximately 106 plants that fall into 67 local therapeutic categories were identified. Despite the fact that exotic species compose a significant fraction of the local medicinal flora, the native species represented the greatest percentage of local uses and indications. Amburana cearensis, Myracrodruon urundeuva, Anadenanthera colubrina, Sideroxylon obtusifolium, and Ziziphus joazeiro, for example, are highly sought after plants, and represent key species in terms of conservation and sustainable management. Our model of utilitarian redundancy has important consequences for testing ethnobotanical hypotheses, as well as for indicating strategies for biodiversity conservation.
