American palm ethnomedicine: A meta-analysis

Background

Animal-based remedies constitute an integral part of Brazilian Traditional Medicine. Due to its long history, zootherapy has in fact become an integral part of folk medicine both in rural and urban areas of the country. In this paper we summarize current knowledge on zootherapeutic practices in Northeast of Brazil, based on information compiled from ethnobiological scientific literature.

Methods

In order to examine the diversity of animals used in traditional medicine in Northeast of Brazil, all available references or reports of folk remedies based on animals sources were examined. 34 sources were analyzed. Only taxa that could be identified to species level were included in assessment of medicinal animal species. Scientific names provided in publications were updated.

Results

The review revealed that at least 250 animal species (178 vertebrates and 72 invertebrates) are used for medicinal purposes in Northeast of Brazil. The inventoried species comprise 10 taxonomic categories and belong to 141 Families. The groups with the greatest number of species were fishes (n = 58), mammals (n = 47) and reptiles (n = 37). The zootherapeutical products are used for the treatment of different illnesses. The most widely treated condition were asthma, rheumatism and sore throat, conditions, which had a wide variety of animals to treat them with. Many animals were used for the treatment of multiple ailments. Beyond the use for treating human diseases, zootherapeutical resources are also used in ethnoveterinary medicine

Conclusion

The number of medicinal species catalogued was quite expressive and demonstrate the importance of zootherapy as alternative therapeutic in Northeast of Brazil. Although widely diffused throughout Brazil, zootherapeutic practices remain virtually unstudied. There is an urgent need to examine the ecological, cultural, social, and public health implications associated with fauna usage, including a full inventory of the animal species used for medicinal purposes and the socio-cultural context associated with their consumption.     

The trade of medicinal animals in Brazil: current status and perspectives

In cities, the trade of medicinal products derived from animals, especially as raw materials, is concentrated in local and traditional markets. The lack of studies on commercialised medicinal faunas restricts an evaluation of the impact of this activity on the exploited species. Within this context, this work reviewed the literature on the trade of medicinal animals in local markets, focusing on urban zootherapy in Brazil and the social factors involved in these practices. Our results reveal that at least 131 species are sold for medicinal purposes in markets and open fairs in Brazil, but results obtained from statistical estimators suggest that this trade actually encompasses a greater richness of species. The medicinal animals sold in Brazil are used to treat 126 illnesses and/or symptoms. Despite the trade of wild animals, including species that are present on the list of endangered species, being forbidden in Brazil, it has been demonstrated that this activity remains common in some Brazilian cities, occurring illicitly and without due monitoring by competent environmental agencies. The results illustrate the need for further research, which should encompass a larger number of cities, especially in regions where information on this subject is currently lacking.     

Medicinal use of fauna by a traditional community in the Brazilian Amazonia

Background

Zootherapy inventories are important as they contribute to the world documentation of the prevalence, importance and diversity of the medicinal use of animals in traditional human communities. The present study aims to contribute with a more valuable example of the zootherapy practices of a traditional community in the Brazilian Amazonia ?C the ??Riozinho do Anfrísio?? Extractive Reserve, in Northern Brazil.

Methods

We used the methods of participant observation and semi-structured interviews, applied to 25 informants. We employed the combined properties of two indices to measure the medicinal importance of each cited species to the studied community, as well as their versatility in the treatment of diseases: the well known Use Value (UV) and the Medicinal Applications Value (MAV) that we developed.

Results

We recorded 31 species of medicinal animals from six taxonomic categories, seven of which are new to science. The species are used for the treatment of 28 diseases and one species is used as an amulet against snakebites. The five species with the highest UV indices are the most popular and valued by the studied community. Their contrasting MAV indices indicate that they have different therapeutic properties: specific (used for the treatment of few diseases; low versatility) and all-purpose (several diseases; high versatility). Similarly, the most cited diseases were also those that could be treated with a larger number of animal species. Ten species are listed in the CITES appendices and 21 are present in the IUCN Red List. The knowledge about the medicinal use of the local fauna is distributed evenly among the different age groups of the informants.

Conclusions

This study shows that the local fauna represents an important medicinal resource for the inhabitants of the protected area. The combined use of the UV and MAV indices allowed identifying the species with the highest therapeutic potential. This type of information about a species may be of interest to pharmacological research, and is crucial to its conservation, since it helps signaling the species that may undergo higher hunting pressures. Data on zootherapy can also be of interesting to ecologists by contributing to indicators of local biodiversity richness.     

Ecological and socio-cultural factors influencing in situ conservation of crop diversity by traditional Andean households in Peru

Background

Zootherapy is important in various socio-cultural environments, and innumerous examples of the use of animal derived remedies can currently be found in many urban, semi-urban and more remote localities in all parts of the world, particularly in developing countries. However, although a number of ethnobiological inventories concerning the use of medicinal animals in human health care have been compiled in Brazil in recent years, zootherapeutic practices in ethnoveterinary medicine (EVM) are poorly described and neglected in favor of human ethnomedicine. In this sense, the purpose of this study was to describe the local zootherapeutic practices in ethnoveterinary medicine of semi-arid of NE Brazil (Caatinga biome) and to contribute to future research about the validation of the effects and side effects of these animal products

Methods

The information obtained through semi-structured interviews was complemented by free interviews and informal conversations. A total of 67 people were interviewed (53 men and 14 women) about the use and commercialization of medicinal animals. To determine the relative importance of each local known species, their use-values (UV) were calculated. Diversity of species utilized was compared, between localities, using rarefaction curves and diversity estimate (Chao2)

Results and Conclusions

A total of 44 animal species (37 vertebrates and 7 invertebrates), distributed among 6 taxonomic categories were found to be used to treat 30 different ailments in livestock and pets. The results of our surveys revealed a rich traditional knowledge of local residents about the use of animals in traditional veterinary medicine. Although it is gradually being discontinued, the perceived efficacy, economic and geographic accessibility were main reasons for popularity of zootherapy in studied areas.     

Vertebrates as a Bactericidal Agent

In Brazil, although a large number of animals are used in traditional medicine (at least 354 species), information about their biological activities is scarce. In this context, the objective of this study was to evaluate the bactericidal potential of zootherapeutic by-products from animals used in Brazilian traditional medicine and discuss the ecological and cultural consequences of such practices. The species analyzed were: Tupinambis merianae (skin), Iguana iguana (skin and body fat), Crotalus durissus (skin and body fat), Boa constrictor (skin), Euphractus sexcinctus (body fat) and Coendou prehensilis (quills). Experiments were performed with standard clinical strains of Escherichia coli (EC-ATCC10536) and Staphylococcus aureus (SA-ATCC 25923). For the microbiological assay, the zootherapeutics were evaluated using serial microdilutions. The results indicate that none of the samples possess inhibitory activity against standard bacterial strains. The in vitro ineffectiveness of the analyzed products demonstrate a necessity for new pharmacological research that encompass a large number of species of medicinal animals as well as highlight the importance of zootherapy in the context of plans for animal conservation.     

Why study the use of animal products in traditional medicines?

The World Health Organization (WHO) estimates that as many as 80% of the world's more than six billion people rely primarily on animal and plant-based medicines. The healing of human ailments by using therapeutics based on medicines obtained from animals or ultimately derived from them is known as zootherapy. The phenomenon of zootherapy is marked both by a broad geographical distribution and very deep historical origins. Despite their importance, studies on the therapeutic use of animals and animal parts have been neglected, when compared to plants. This paper discusses some related aspects of the use of animals or parts thereof as medicines, and their implications for ecology, culture (the traditional knowledge), economy, and public health.     

Primates in traditional folk medicine: a world overview

• 1 Almost 50% of primate species are in danger of becoming extinct, according to the criteria of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. This is partly because of their consumption by humans. The reasons for hunting vary by region. One pretext is the medicinal or magical value of products derived from these animals.
• 2 In this paper, we provide an overview of the global use of primates in traditional folk medicines as well as identifying the species used as remedies associated with folk beliefs. Some important questions relating to the conservation of primates are addressed.
• 3 Our results revealed that at least 101 species of primates, which belong to 38 genera and 10 families, were used in traditional folk practices and in magic–religious rituals throughout the world.
• 4 Of the 101 species of primates recorded in our review, 12 species were classified as Critically Endangered, 23 as Endangered, 22 as Vulnerable, seven as Near Threatened, 36 as Least Concern and one as Data Deficient in the IUCN Red List. All species were also included in The Convention on International Trade in Endangered Species of Wild Fauna and Flora Appendices I or II, although the reasons for their inclusion were not necessarily related to their medicinal use.
• 5 The widespread utilization of primates in traditional medicine is evidence of the importance of understanding such uses in the context of primate conservation as well as the need for considering socio‐cultural factors when establishing management plans concerning the sustainable use of these mammals.

     

Ethnobotanical notes about some uses of medicinal plants in Alto Tirreno Cosentino area (Calabria, Southern Italy)

The present zootherapeutic study describes the traditional knowledge related to the use of different animals and animal-derived products as medicines by the Saharia tribe reside in the Shahabad and Kishanganj Panchayat Samiti's of Baran district of Rajasthan, India. A field survey was conducted from April to June 2006 by performing interview through structured questionnaire with 21 selected respondents, who provided information regarding use of animals and their products in folk medicine. A total of 15 animal species were recorded and they are used for different ethnomedical purposes, including cough, asthma, tuberculosis, paralysis, earache, herpes, weakness, muscular pain etc. The zootherapeutic knowledge was mostly based on domestic animals, but some protected species like the peacock (Pavo cristatus,), hard shelled turtle (Kachuga tentoria), sambhar (Cervus unicolor) were also mentioned as medicinal resources. We would suggest that this kind of neglected traditional knowledge should be included into the strategies of conservation and management of faunistic resources. Further studies are required for experimental validation to confirm the presence of bioactive compounds in these traditional remedies and also to emphasize more sustainable use of these resources.     

Mapuche perceptions and conservation of Andean <Emphasis Type="Italic">Nothofagus</Emphasis> forests and their medicinal plants: a case study from a rural community in Patagonia,Argentina

In a Mapuche community situated in the sub-antarctic forest of the northwest of Argentine Patagonia, analysis was carried out on forest environmental perception and its relation to the resilience of the body of traditional botanical knowledge regarding medicinal plants. Data was obtained on the ethno-classification and differential use of the forest gathering environment with respect to its practical and cultural value. Semi-structured interviews were carried out with 30 randomly chosen inhabitants, and the data were analysed using qualitative methods and non-parametric statistics. Most citations (64.5%) were of species gathered in Nothofagus antarctica forest, 26.2% were of species from N. pumilio forest, and 20.3% referred to species from a mixed forest, with N. dombeyi. The forests studied have low values for similarity in terms of medicinal species richness, indicating a unique offer of therapeutic resources in each one. The use of the different forest types seems to be associated with the search for therapeutic resources for specific ailments. However, the redundancy of functions of species in each forest type can offer alternative remedies, which provides plant conservation, security and the possibility of reorganisation of their traditional medicinal knowledge. This case study showed the importance of considering folk systems and the role that this knowledge has played in plant resource management and forest protection. Different forests are used and valued differentially, not only with regard to usefulness but also in symbolic-religious terms, and together they fulfil a cushioning function, protecting holistically traditional botanical knowledge, people’s health and forests. It is of great importance, therefore, that conservation policies favouring environmental heterogeneity are implemented, and that local inhabitants participate in the development of management plans.     

Ethnomedicine in Tonga

Local medical practices in this Pacific archipelago are reviewed, the folk taxonomy and medicinal uses of 71 plants are discussed, and the medicinal applications of each species in some other regions of the Pacific are enumerated. Included are the plant parts used, Tongan names, the illnesses, and the preparations of the remedies.     

Medicinal plants of Otwal and Ngai Sub Counties in Oyam District, Northern Uganda

Arunachal Pradesh, the easternmost part of India, is endowed with diverse natural resources and inhabited by a variety of ethnic groups that have developed skills to exploit the biotic resources of the region for food and medicines. Information on animals and animal parts as components of folk remedies used by local healers and village headmen of the Nyishi and Galo tribes in their respective West Siang and Subansiri districts were obtained through interviews and structured questionnaires. Of a total of 36 vertebrate species used in treatments of ailments and diseases, mammals comprised 50%; they were followed by birds (22%), fishes (17%), reptiles (8%) and amphibians (3%). Approximately 20 common complaints of humans as well as foot and mouth disease of cattle were targets of zootherapies. Most commonly treated were fevers, body aches and pains, tuberculosis, malaria, wounds and burns, typhoid, smallpox, dysentery and diarrhoea, jaundice, and early pregnancy pains. Very few domestic animal species (e.g., goat and cattle) were used zootherapeutically. More frequently it was wild animals, including endangered or protective species like hornbill, pangolin, clouded leopard, tiger, bear, and wolf, whose various parts were either used in folk remedies or as food. Some of the animal-based traditional medicines or animal parts were sold at local markets, where they had to compete with modern, western pharmaceuticals. To record, document, analyze and test the animal-derived local medicines before they become replaced by western products is one challenge; to protect the already dwindling populations of certain wild animal species used as a resource for the traditional animal-derived remedies, is another.

A Global overview of canids used in traditional medicines

Canids are among the mammal species most frequently used in traditional folk medicine around the world. In this context, this paper assesses the global use of canids in traditional folk medicine and their implications. Our review indicated that 19 species of canid are used in traditional medicine worldwide, representing 54.2% of described canid species. Of the species in medicinal use, two are listed as Endangered and three as near threatened on the IUCN Red List. For some species medicinal use represents an additional direct pressure that may have contributed to declines of natural populations. In addition, use of medicinal animals may have indirect impacts on the conservation of other species through the spread of disease. To minimize both harvest impacts and disease spread, guidance on use of medicinal species may be useful. This could include an exploration of the use of alternatives and implementation of sanitary measures.     

中国药用植物可持续利用战略框架简述

China is the birth-place of Traditional Chines Medicine (TCM) and has a rich diversity of medicinal plant resources. With the rapid increase in consumer demands for crude drugs and natural health products, many medicinal plant species are threatened with extinction from overexploitation and habitat destruction. To ensure the sustainable use of medicinal plant resources, we discuss in this article, a conservation framework consisting of conservation strategies, cultivation practices and various technologies. Conservation strategies include establishing in-situ and ex-situ conservation centers, setting up government policies and regulations, establishing methods for resource surveying and trade monitoring and establishing and enforcing Good Agricultural Practices (GAP). In terms of technologies, we use a remote multi-level sensing system and DNA barcoding technologies as examples to demonstrate their roles in the conservation and sustainable use of medicinal plant resources in China.     

A review on ethno-medicinal plants used in traditional medicine in the Kingdom of Saudi Arabia

The traditional medicine based on medicinal plants in the Kingdom of Arabia Saudia presents a strong relationship belonging to natural remedies, health, diet, and folk healing practice recognized by a specific culture. The aim of the current study is to carry out an ethnobotanical review on medicinal plants used in traditional medicine in the Kingdom of Arabia Saudia including information on plant species, used parts, preparation method as well as medical uses. Earlier published data in journals, textbooks, periodicals, websites, and databases written in pharmacological evidence of Suadi medicinal plants were based on gathering information. The present review work reported that 96 species belonging to 47 families have been used in Saudi Pharmacopeia. Amaranthaceae has the highest number of plant species (7) Followed by Asteraceae, Apocynaceae, and Fabaceae with 5 plant species in each. The inventoried plant species in the current work are frequently used for the treatment of various illnesses and to ensure the medication safety of Saudi people. The biological analysis of plant form used in Saudi natural remedies showed the dominance of herb and subshrub form with a percentage of 43% and 30% respectively. The most used preparation method of plant drugs, which used in Saudi Alternative medicine was decoction and infusion. The whole plant, leaves, seeds, and aerial parts were the most useful plant parts in natural preparation in Saudi traditional medicine with a percentage of 29%, 28%, 7%, and 5% respectively as reported in the present review work. The present review work gives big data about medicinal plants used in traditional medicine in the Kingdom of Saudi Arabia including data about plant species, used parts, preparation method as well as medical uses.     

植物学与中草药物研究

植物学和医药在科学启蒙时期是合而不分的。东西文化相同。中国古代本草(ancient Chinese materia medica),欧洲中世纪的药物书籍(European medieval herbals),共同证明这件史实。欧洲17—18世纪经典的植物著述,是那个时代医生们业余的工作成果;19世纪亚洲美洲的植物志,以及植物地理知识,基本上是舍弃医药职业从事植物研究之先锋植物学家的成绩。现代植物学知识和方法,更是研究中草药不能缺少而且不可忽略的基础。试举三例说明,职业植物学家如何以正确鉴定和合法命名,解决国际间药物交流问题,并怎样以植物解剖知识澄清药材商品素质混乱情形。凡是能力强工作负责的药用植物学家,都是热心的环境保护者,因为他们工作的地方,既是标本馆实验室,又是野外的大自然;他们确知,自然没有任何取之不尽用之不竭的资源,更没有丰富的药物资源。加之以人们无情地挖掘,任意地采集,无数有药用价值的植物,己遭到不可挽救的毁灭,绝了种!有的也接近灭绝的危运。再看未来,植物学家除了研究植物本体之外,更加上唤起民众爱惜自然植被保护环境的重要职责,并且筛选有利于人畜保健的植物,逐一研究其生境与其成活的环境条件,和农业科学家合作引种驯化,以达成合理利用中草药植物资源的要求。     

Herbal plants in the traditional medicine of Bahrain

Plant samples collected in Bahrain and data reported in the literature indicate the flora of Bahrain to contain 52 species (49 genera; 20 families) of medicinal interest. Of these plant species 20 appear to be indigenous and are being used in traditional herbal remedies for numerous afflictions. Preparation of such remedies appears to be simple and includes boiling, infusions, extraction of milled dry or fresh leaves, flowers, seeds or whole plants. Direct consumption of plant parts, raw or cooked, is also practiced. None of these plants has been studied systematically to evaluate their medicinal potential.

Systematics is crucial for the traditional Chinese medicinal studies and industry of macrofungi

Recently, it has been indicated that systematics is of no value to the traditional Chinese medicinal studies and industry of macrofungi. As a fungal taxonomist, I use three genera of the most famous medicinal macrofungi, viz. Sanghuangporus, Ganoderma and Ophiocordyceps, as examples to rebut this opinion. Generally, the well-established systematics are helpful in using correct Latin names for fungal species in medicinal studies; furthermore, the resulting medicinal functions can be exactly matched to a particular species; finally, the particular species can be applied for permissions of utilization in traditional Chinese medicinal industry. Therefore, systematics is crucial for unlocking the potential of macrofungi as valuable resources to be developed in the traditional Chinese medicinal studies and industry, and should continue to be of interest to not just fungal taxonomists but also biochemists, pharmacists and businessmen.     

Cultural,economic, and ecological factors influencing management of wild plants and mushrooms interchanged in Purépecha markets of Mexico

Background

Traditional markets outstandingly contribute to conservation of biocultural diversity, social relations, and cultural values. These markets reflect life strategies and forms people of a region interact with their biodiversity and territories, as well as traditional ecological knowledge and management practices. To understand the factors motivating plant and mushroom management, we analyzed the resources cultural and economic values, their role in people’s subsistence, and the relation of these values with the resources spatial and temporal availability. Our study based on the supposition that traditional markets are settings of interchange of resources with the highest importance for people’s life in a region. Also, that the cultural, economic, and ecological factors influence values of the resources, and the demand on them determine pressures on the most valuable resources which, when scarce, motivate management innovation, otherwise become extinct.

Methods

We documented cultural, economic, and ecological aspects, as well as management techniques of wild and weedy plants and mushrooms interchanged in three traditional markets of the Pátzcuaro Lake region, in central-western Mexico. For doing that, from February 2015 to March 2018, we conducted 175 visits to markets and 89 semi-structured interviews to producers, gatherers, and sellers of wild and weedy plants and mushrooms. Based on participant observation and interviews, we identified variables related to culture, economic, and ecological aspects, as well as management regimes of resources and management systems, which were documented and used as indicators for quantitative analyses. Through principal components analyses (PCA), we determined the indexes of cultural and economic importance (ICEI), management intensity (IMI), and ecological risk (IR) of the resources studied. For conducting that, we classified plant and mushroom species according to their cultural, economic, ecological, and technological indicators, respectively. The score of the first principal component was considered as the index for each group of variables, respectively. To identify relations between cultural importance and risk, we performed linear regression analyses between ICEI and IR indexes.

Results

We recorded 57 species of wild and weedy plants used as food, medicine, and ornamental, and 17 species of edible mushrooms. The variables with the highest weight in the ICEI are related to the need of a resource according to people, its recognizing, the number of communities and markets offering it in markets, its explicit preference expressed by people, the effort invested in obtaining it, and the form it is interchanged. Gathering is practiced in all mushrooms and wild and weedy plants from forests and agricultural areas; 11 species in addition receive 1 or more forms of management (enhancing, selective let standing, propagation through seeds or vegetative parts, transplantation, and/or protection). The management intensity and complexity are explained by variables related to management practices and systems. Plants receiving selective management have the higher management intensity. Silvicultural management (in situ management in forests) was recorded in all species of mushrooms, as well as in more than 80% of medicinal, ceremonial and ornamental plants, and in more than 50% of the edible plants. In agricultural systems, people manage more than 90% of the edible plants recorded to be under a management regime, 25% of the managed medicinal plants, and 30.7% of the managed ceremonial and ornamental plants. In homegardens, people manage 41.6% of the medicinal plants recorded and 26.6% of the edible plants, to have them available near home. Nearly 63% of the species interchanged in the markets studied are gathered in forests without any other management form. In this group are included all mushroom species, 61.5% of ceremonial/ornamental plants, 50% of medicinal, and 33.3% of edible plants. The linear regression between ICEI an IER is significantly negative for edible species with high management intensity R²?=?0.505 (p?=?0.0316), because of their management. But in medicinal and ornamental plants, the risk is high if the cultural importance increases, even when management practices like transplanting and propagation in homegardens are carried out.

Conclusions

Traditional markets are settings of interchange of products, knowledge, and experiences, where the ongoing factors and processes motivating management innovation can be identified and documented. This approach allows documenting processes occurring at regional level but would be benefited from deeper studies at local level in communities.
