Knowledge and use of medicinal plants by local specialists in an region of Atlantic Forest in the state of Pernambuco (Northeastern Brazil)

This paper investigates the wealth of medicinal plants used by the Apatani tribe of Arunachal Pradesh. Apatani have traditionally settled in seven villages in the Ziro valley of Lower Subansiri district of Arunachal Pradesh in the Eastern Himalayan region of India. The present study has resulted in the documentation of 158 medicinal plant species used by the Apatani group of villages. These medicinal plant species were distributed across 73 families and 124 genera. Asteraceae was the most dominant family (19 species, 11 genera) of medicinal plants, followed by Zingiberaceae, Solanaceae, Lamiaceae and Araceae. For curing ailments, the use of aboveground plant parts was higher (80%) than the belowground plant parts in the Apatani group of villages. Of the aboveground plant parts, leaf was used in the majority of cases (56 species), followed by fruit. Different belowground plant forms such as root, tuber, rhizome, bulb and pseudo-bulb were used by Apatani as a medicine. About 52 types of ailments were cured by using these 158 medicinal plant species. The results of this study are further discussed in the changing socio-economic contexts.     

Traditional Beverage Plants Used by Dai Villagers in Xishuangbanna

One hundred and fourteen plant species which belonging to 43 families and 93 genera were recorded in this study. All these species were used as traditional beverage plants by Dai people in two Dai villages (Man’an and Mansan)of xishuangbanna and 65 . 8% of the plants may hold medicinal functions. The results indicated that the species and the number of species were quite different between the two villages , and the difference between genders was not significant. However, the results of ANOVA showed that there was not significant difference between the average number of plant species mentioned in the villages and among genders, and the mean number of plant species mentioned in young group was significantly lower than that in old group, especially inMan’an village where transportation is much convenient. The study suggested that the indigenous knowledge was on the way of loss with the influence of exotic culture.     

Medicinal plants of Erute county,Lira district,Uganda with particular reference to their conservation

A medicinal plant study was carried out in eighteen parishes and 54 villages of Erute county, Lira district, Uganda. Parishes and villages were selected using stratified random sampling techniques. Questionnaires, interviews and discussions with the local people were used to obtain information on the names of the plants, their medicinal uses and conservation methods. The number of the medicinal plants species used was 180 belonging to 144 genera and 57 families of flowering plants. The major families recorded for medicinal purpose included Fabaceae (37 species), Asteraceae (26 species), Euphorbiaceae (eleven species), Vitaceae (eight species), Verbenaceae (seven species), Poaceae (six species), Solanaceae (five species), and Rubiaceae (four species). There is a need for putting in place measures to conserve these plants. Unfortunately, most of the healers or users were not interested in cultivation of the plants. The situation could worsen with the social changes and demand for land for agriculture in the district.     

西双版纳傣族传统饮料植物利用的研究

利用民族植物学与人类学相结合的方法,对西双版纳州曼伞、曼安两个傣族村寨利用传统饮料植物的情况进行了调查。结果显示,两个村寨利用的传统饮料植物有114种,隶属43科、93属,其中65．8％的种具有药用价值。两村寨利用传统饮料植物的种类及物种数有较大不同,而村民传统饮料植物知识在性别间无明显差异。ANOVA分析表明,传统饮料植物平均被提及的物种数在村寨、性别间无明显差异,但在不同年龄组间有显著差异,即随着年龄减小,访谈中人均提及的物种数呈下降趋势,这种趋势在交通较为便利的曼安寨更为明显,表明环境变化和外来文化等对植物传统利用知识的传承有很大影响。     

Local knowledge and socio-economic determinants of traditional medicines' utilization in livestock health management in Southwest Nigeria

Background

An ethnomedicinal study was conducted to document medicinal plants used in the treatment of ailments in villages surrounding Kimboza forest reserve, a low land catchment forest with high number of endemic plant species.

Methods

Ethnobotanical interviews on medicinal plants used to treat common illnesses were conducted with the traditional medical practitioners using open-ended semi -structured questionnaires. Diseases treated, methods of preparation, use and habitat of medicinal plants were recorded.

Results

A total of 82 medicinal plant species belonging to 29 families were recorded during the study. The most commonly used plant families recorded were Fabaceae (29%), Euphorbiaceae (20%), Asteraceae and Moraceae (17% each) and Rubiaceae (15%) in that order. The most frequently utilized medicinal plant parts were leaves (41.3%), followed by roots (29.0%), bark (21.7%), seeds (5.31%), and fruits (2.6%). The study revealed that stomach ache was the condition treated with the highest percentage of medicinal plant species (15%), followed by hernia (13%), diarrhea (12), fever and wound (11% each), and coughs (10%). Majority of medicinal plant species (65.9%) were collected from the wild compared to only 26.7% from cultivated land.

Conclusions

A rich diversity of medicinal plant species are used for treating different diseases in villages around Kimboza forest reserve, with the wild habitat being the most important reservoir for the majority of the plants. Awareness programmes on sustainable utilization and active involvement of community in conservation programmes are needed.     

Diversity of Medicinal and Food Plants as Non-timber Forest Products in Naban River Watershed National Nature Reserve (China): Implications for Livelihood Improvement and Biodiversity Conservation

Diversity of Medicinal and Food Plants as Non-timber Forest Products in Naban River Watershed National Nature Reserve (China): Implications for Livelihood Improvement and Biodiversity Conservation. Non-timber forest products (NTFPs) play an important role in rural livelihoods. People living in and around forests are dependent on a variety of NTFPs for their subsistence and for income generation. This paper gives a general overview on the diversity of NTFPs in the Naban River Watershed National Nature Reserve, with a focus on medicinal and food plants. Data on NTFPs use were gathered through an ethnobotanical inventory with semistructured, free-listing, and household socioeconomic interviews. Interviews were supplemented with voucher collections. Bamboo shoots were analyzed further as proxy NTPF. It was hypothesized that there is no significant difference between collection amounts of bamboo shoots and their contribution to the household income between the villages studied. A rapid vulnerability assessment (RVA) was conducted to identify vulnerable and threatened species. A total of 480 plant species (25% of recorded flora) from 117 families and 334 genera are used as NTFPs by the local people. Results revealed that there is a significant difference in the collection and contribution of bamboo shoots to household income among the villages. However, their contribution to per-capita income is very low, and they are mainly used in households. Vulnerability assessment showed that most of the medicinal species have moderate vulnerable status and that most of the food species have less vulnerable status. Some medicinal plants, such as Paris polyphylla var. yunnanensis, are overexploited and getting scarce. Sustainable harvest and management strategies should be implemented to prevent overexploitation of these species.     

Importance of traditional protected areas for the collection of medicinal plants,Kongo‐Central (DRC)

The Mbanza‐Ngungu region (Kongo‐Central province, DRC) currently faces continued forest deterioration. Many of these forests were traditionally protected areas of which to date, only traces are left. The aim of this study was to evaluate and compare the importance of forest remnants and other components of the landscape for the collection of medicinal plants in the Mbanza‐Ngungu Region, DRC. Between February 2009 and May 2012, semi‐structured interviews and participatory observations were conducted in this region with 51 traditional healers selected by means of the ‘snowball method’. Local importance of medicinal plants was determined by the medicinal Use Value parameter. Statistical analyses were carried out with SPSS 20.0 and based on chi‐square test, analysis of variance and post hoc comparison of means. Our results show that the forest remnants remain the main medicinal species provider: 68 species against 62 for agro‐ecosystems. However, the total number of citations for medicinal species uses is higher for agro‐ecosystems (293) than for forest remnants (233), and this difference is significant (P < 0·05). This could be explained, among others, by the fact that some forest remnants are respected or protected by the villagers for religious and ritual purposes (Sangi). This also points to the importance of agro‐ecosystems and secondary vegetation as provider of medicinal plants around rural villages, as seen elsewhere in the tropics.     

Indigenous oral knowledge of wild medicinal plants from the Peren district of Nagaland,India in the Indo Burma hot-spot

The paper report the oral traditional knowledge of wild medicinal plants usage by the indigenous ethnic tribal community from the Peren district of Nagaland, India in the Indo-Burma Hotspot. The pioneer study was based on the semi-structured interview of locals (N = 240) in the 12 villages of the Peren District during 2014 ‐ 2018. In total, 179 ethnomedicinal plants from 140 genera and 72 families were documented and identified. The medicinal plants were used for the treatment of 96 different ailments grouped into 18 categories. The medicinal plants also showed high versatile nature with 85 species reported to treat five / eleven different ailments, respectively. The ethnobotanical information obtained from the field documentation will contribute in the development of potential drugs in the future from the diverse wild medicinal plants of the region and contribute towards the preservation of the oral tradition that is disappearing.     

The Investigation on Utilization of Wild Medicinal Plants in Dietary Culture of Quanzhou,Southern Fujian

An ethnobotanical survey on the medicinal plant species marketed in Quanzhou, southern Fujian, was conducted in order to document traditional medicinal knowledge and application of medicinal plants in dietary. In addition to literature review, data was obtained using ethnobotanical tools and methods, including personal interviews during field trips, collecting herbarium specimens, and species identification by cross referencing. The results showed that: 1) There are 148 wild medicinal species, belonging to 56 plant families and 117 genera present in Quanzhou, southern Fujian. Among them, 46 species are edible wild herbs, 37 species are medicinal plants, 38 species are used as tea substituting plants or herbal tea,22 species are wild fruits, 4 species are used as spices and 1 species is used to make bean jelly; 2) The plant families which comprise a major part of the pool are Compositae, Lamiaceae, Rosaceae, Leguminosae, Rubiaceae, Liliaceae, Orchidaceae and Moraceae; 3) This study explored the utilization of the medicinal plants in Quanzhou area, and proposed methods to inherit the culture of using wild plants in dietary, as well as methods to conserve the edible medicinal wild plant resources.     

Plants used by the bhat community for regulating fertility

A survey was conducted among medicinal plant sellers, healers, priests and local people in the rural population of Bhat, India. In this rural community medicinal plants are used for regulating fertility. Due to the fact that the majority of the Bhat community is illiterate, oral interviews were held in the villages. The information was then recorded. Plant samples were collected and preserved for future reference. Information on 28 plants and 11 recipes for doses from 2 or more vegetable species are presented, and popular names, empirical properties, and manner of using recipes are described. More than 90% of the information gathered was consistent among the informants, but some of the informants differed in their reports on the way to use the same plants. There is no certainty as to which of the plants are effective. Since the Bhat community has frequently observed the positive effects of their preparations, they have much faith in their recipes. The acceptability of these preparations is quite high among 95% of the Bhat population.     

Food, feed or medicine: The multiple functions of edible wild plants in Vietnam

Many of the edible wild plants that are included in local food baskets have both therapeutic and dietary functions. Such medicinal foods have been part of Eastern medicinal theories since ancient times and have recently received attention in the USA and Europe within the fields of functional foods, neutraceuticals and phyto-nutrients. This paper provides an example from Vietnam of the continued use of a multitude of edible wild vegetables. Vietnamese traditional medicine also holds an important position within the health care system and many of the plants that are used have both dietary and medicinal functions. Using a combination of qualitative and quantitative techniques (Rapid Rural Appraisal and Food Frequency Questionnaires), information on over 90 species of edible wild plants was obtained from 4 villages in the Mekong Delta and the Central Highlands. About a third of the plants also had therapeutic roles, forty percent were used also as livestock feeds and one fifth were used as food/livestock feed/ medicine. From a nutrition viewpoint it is important to pay attention to this group of traditional foods for several reasons. Their direct nutritional contribution is often significant but neglected. Very little is known about the health benefits of regular consumption of small quantities of medicinal foods and an important “medicinal role” of traditional plant medicines may be the contribution of small quantities of trace minerals and vitamins. The parallel functions as livestock feeds make animal products more accessible to poor households and help improve the quality of their diets.     

Medicinal plants in the southern region of the State of Nuevo León,México

Background

Although the flora of the State of Nuevo León is well known, there are few records of ethnobotancial information. An ethnobotanical study was undertaken in order to know the medicinal plants used by people living at the scrublands and oak-pine forest areas in the southern Nuevo León. Collection of plants specimens and interviews were carried out among the people of the municipalities of Aramberri, Galeana, and Zaragoza. Since former studies in the region are scarce, the aim of this work was to record the medicinal species and their uses in the scrublands and oak-pine forest areas, of southern Nuevo León, Mexico, and also to know if there are differences in the number of species and number of uses knowledge by people.

Methods

Field work was carried out over a 2 years period; useful plants were collected and a total of 105 people from 46 different villages were interviewed. A database was compiled using data collected by means of semi structured interviews. The data were analyzed by means of non-parametric statistics, using goodness-of-fit test (Chi-squared) (number of species known by people of each municipality, number of uses known by people of each municipality), Chi-squared modified to incorporate the Yates Correction (number of species known by people living at scrublands and oak-pine forest); the Kruskall-Wallis test (number of species known by women and men of the three municipalities), and the Spearman’s rank correlation coefficient (age and number of species known, and age and number of uses).

Results

A total of 163 medicinal plant species were recorded in the study area, comprising 108 wild and 55 cultivated plants. A total of 117 species were recorded in the oak-pine forest, and 111 in the scrublands area, a total of 68 were recorded in both areas; 68 medicinal species are used in all three municipalities, 40 wild and 28 cultivated. We documented 235 different medicinal uses. The most common plant parts used for medicinal purposes were found to be leaves (123 species), stems (55), fruits (28), roots (17), and bark (14). No differences were noted in the number of medicinal plant species identified among people, but differences were significant in their knowledge with respect to the number of uses among people of the three municipalities studied; people from both, scrublands and oak-pine forest know similar number of species and number of uses. Men and women of the three different municipalities knew statistically the same number of species and number of uses. There was no correlation between resident’s age and number of species known and resident’s age and number of uses either in Galeana or in Aramberri, but, there was high correlation among these variables in Zaragoza.

Conclusion

In southern Nuevo León people use at least 5% of the total State flora as medicinal plants, and most of these species are included in few plant families. Most of medicinal species are wild and indigenous to the region. The two most important major plant communities, scrublands and oak-pine forest provide almost the same number of medicinal species. A third of the medicinal flora recorded are used in all three municipalities, most of them are wild. Leaves, stems and fruits are the plant parts most commonly used for healing, and boiling is the most common method used for this purpose. Men and women from the three municipalities are familiar with nearly the same number of species; however, their knowledge of the number of uses varies significantly. In Galeana and Aramberri there was no correlation between a person’s age and number of species recognized, however, in Zaragoza, there existed a high correlation between these two factors.

Medicinal Plant Knowledge Among Lay People in Five Eastern Tibet Villages

Tibetans in five villages in the Mount Khawa Karpo area of the Menri (Meili Xueshan in Chinese) range, Northwest Yunnan, People’s Republic of China, were interviewed about their knowledge of a number of medicinal plants and their uses. There was large variation in people’s knowledge with significant differences among the villages and between men and women. Most of the reported knowledge focused on a small number of commercial plants and their uses. In comparison with Tibetan doctors, villagers generally knew fewer applications and focused on general health remedies. Many people collected medicinal plants for their own use as well as for sale, but also obtained medicinal plant remedies from markets and Tibetan doctors, and often used traditional Tibetan healthcare in conjunction with biomedical treatment.

Ethnobotany of Immunomodulatory Treatments Used by the Q’eqchi’ Maya of Belize

Using a quantitative ethnobotanical methodology, we identified 107 plant species belonging to 49 families used by Q’eqchi’ Maya healers in the treatment of symptoms from 14 usage categories related to inflammation. The families with the largest number of medicinal species were Piperaceae, Araceae, Asteraceae, Fabaceae, and Adiantaceae with five or more medicinal species. Healer consensus for plant species was high, with 56 species (52%) being used by all the healers, and consensus for usage categories was also high, as informant consensus factor (FIC) values for each category were greater than 0.4.

     

Forest age correlates with fine-scale spatial structure of Matsutake mycorrhizas

Examining the fine-scale spatial structure of fungal populations can tell us much about how individual species reproduce and disperse throughout natural landscapes. Here we study the fine-scale genetic structure of Tricholoma matsutake, a prized edible and medicinal mushroom, by systematic sampling of mycorrhizas within fairy rings in 50-y-old and old-growth forests in two villages. Using single nucleotide polymorphism DNA markers we show that mycorrhizas in both forest age classes in both villages showed high levels of genotypic diversity, consistent with a reproductive life history predominated by outcrossing via basidiospore dispersal. Both the percentage of polymorphic loci within fairy rings, as well as genotype diversity were higher in old-growth compared to 50-y-old forests. Fifty-year-old forests showed significant spatial autocorrelation between pairs of mycorrhizas up to 42 m, and a pattern consistent isolation-by-distance structure. Spatial patterns in old-growth forests were random. Furthermore, AMOVA analysis indicates that 11 % of molecular variance in 50-y-old forests is partitioned between villages, whereas no significant variance is partitioned between villages in old-growth forests. We conclude that populations of T. matsutake in 50-y-old forests are the result of a founder effect maintained by local inoculation sources. This pattern attenuates as forests age and accumulate inocula from more distance sources. We speculate on how genetic mosaicism within T. matsutake fairy rings may structure populations within a chronosequence. Finally, we discuss how population spatial dynamics and dispersal strategy in T. matsutake contrast with other ectomycorrhizal species.     

Uses and Conservation of Plant Species in a National Park—A Case Study of Ben En, Vietnam

Uses and Conservation of Plant Species in a National Park—A Case Study of Ben En, Vietnam. This paper surveys the use of wild and cultivated plants by local people in Ben En National Park, Vietnam, and analyzes its impact on the conservation status of some of the utilized species. A total of 208 species used for a range of nonmedicinal purposes are listed. See Hoang et al. (2008a) for 230 medicinal plants used in the park. Most species are used for food. The use of plants contributes very significantly to the livelihood of local people in the park, but the current use patterns are not sustainable and would lead to local extinction of rare and endangered species if no additional conservation measures are introduced. Men collect nonmedicinal plants more often than women. A total of 38 useful plant species are commercialized, and contribute 12% of the average income of individual households. Bamboo shoots of Schizostachyum funghomii (Poaceae) are the most important for income generation. The monetary equivalent of noncommercialized useful plants probably far exceeds the value of the traded plant products. Plant use is independent of the ethnicity of the different populations living in the park. Larger households make use of a greater variety of useful plant species than small families. Abundant species in the forest have a higher use index (UI) than less common species. Out of the 208 useful species, as many as 27 were found to be endangered locally, many more than the 11 or 8 endangered species included in national or global red lists. Currently, useful plants, especially important timber trees, are more abundant in the less disturbed parts of the park, far away from the villages, indicating the pressures of illegal logging and harvesting near villages on the ecosystems.     

Traditional medicinal plant knowledge and use by local healers in Sekoru District, Jimma Zone, Southwestern Ethiopia

The knowledge and use of medicinal plant species by traditional healers was investigated in Sekoru District, Jimma Zone, Southwestern Ethiopia from December 2005 to November 2006. Traditional healers of the study area were selected randomly and interviewed with the help of translators to gather information on the knowledge and use of medicinal plants used as a remedy for human ailments in the study area. In the current study, it was reported that 27 plant species belonging to 27 genera and 18 families were commonly used to treat various human ailments. Most of these species (85.71%) were wild and harvested mainly for their leaves (64.52%). The most cited ethnomedicinal plant species wasAlysicarpus quartinianus A. Rich., whose roots and leaves were reported by traditional healers to be crushed in fresh and applied as a lotion on the lesions of patients ofAbiato (Shererit). No significant correlation was observed between the age of traditional healers and the number of species reported and the indigenous knowledge transfer was found to be similar. More than one medicinal plant species were used more frequently than the use of a single species for remedy preparations. Plant parts used for remedy preparations showed significant difference with medicinal plant species abundance in the study area.     

药用植物资源利用的一种分析模型

在系统分析药用植物资源利用的各方面因素基础上,以资源利用模式为研究切入点,提出了一个基于资源利用模式和模式形成路径的分析模型（Pattem—Path Model）,用于整体分析某一药用体系中植物资源的开发利用水平和发展过程。应用该分析模型对2005版中国药典使用的药用植物资源（549种高等植物）进行了分析,结果表明：中国药典中应用的药用植物,其资源利用发展较成熟（供应持续性良好的植物资源占79％,暂不能持续供应的占21％）;但是资源利用的发展过程不尽合理（部分植物资源的栽培开展滞后于野生资源的枯竭,占40％）。该结论与已有定性评价观点相一致,并量化地体现出资源利用的发展水平和发展过程,能够推广应用到其他药用体系的资源利用分析,为药用植物资源的利用管理提供决策依据。
