Ethnobotanical study of medicinal plants in Ganta Afeshum District,Eastern Zone of Tigray,Northern Ethiopia

Background

Starting from the ancient time, the people of Ethiopia use medicinal plants as traditional medicine to heal different human and livestock ailments. This ethnobotanical study of medicinal plants was carried out in Ganta Afeshum District, Eastern Zone of Tigray, Northern Ethiopia, to identify medicinal plant species used by the local community to treat various human and livestock ailments.

Methods

A total of 78 informants (54 men and 24 women) were selected to collect ethnobotanical information from four study sites. Among the 78 informants, 20 key informants were selected purposefully; the other 58 informants were selected randomly by lottery method. Ethnobotanical data were collected using semi-structured interviews, field observations, guided field walks, and group discussions and were analyzed by preference ranking, paired comparison, direct matrix ranking, informant consensus factor, fidelity level (FL), use-value, independent samples t test, and Pearson correlation coefficients.

Results

A total of 173 medicinal plants were collected and identified that were distributed across 77 families and 156 genera. The family Fabaceae stood first by contributing 17 (9.8%) species followed by Lamiaceae and Solanaceae with 9 (5.2%) species each. Rhamnus prinoides was reported for the treatment of many of the described diseases. One hundred sixteen (67.1%) medicinal plant species were collected from natural vegetation, 34 (19.7) were from home gardens, 13 (7.5%) from farmland, and 10 (5.8%) were from natural vegetation and home gardens. The most widely used life form was herbs (69 species, 39.9%) followed by shrubs (58 species, 33.5%). The most commonly used part of the medicinal plants was the leaves followed by roots. The plants were prepared by grinding, powdering, squeezing, roasting, and burning and were administered through oral, dermal, nasal, anal, ocular, and vaginal, and on the surface of the teeth. The most commonly used applications were by drinking, smearing, eating, fumigation, and chewing. There was no difference between men and women informants, showing that the two sexes had similar knowledge in the use of traditional medicinal plants. Educational level and medicinal plant knowledge of informants were negatively correlated; whereas age and medicinal plant knowledge of informants were positively correlated.

Conclusions

Ganta Afeshum District is relatively rich in diversity of medicinal plant resources accompanied with a rich indigenous knowledge within the local communities to harvest and effectively use to prevent different human and livestock ailments. However, nowadays, deforestation, agricultural expansion, overgrazing, drought, and overexploitation are threatening these properties. Therefore, people of the study area should apply complementary conservation approaches (in situ and ex situ) for sustainable use of these resources and to prevent species extinction.

     

Ethnomedicinal study of plants used for human ailments in Ankober District,North Shewa Zone,Amhara Region,Ethiopia

Background

Ankober District has long been inhabited by people who have a long tradition of using medicinal plants to treat human ailments. Overexploitation of medicinal plants coupled with an ever-increasing population growth, deforestation and agricultural land expansion threatens plants in the area. Hence, this study aimed at documenting and analyzing the plant-based ethnomedicinal knowledge of the people in order to preserve the dwindling indigenous knowledge.

Methods

Ethnobotanical data were collected using semi-structured interviews, focus group discussions, participant observation and walk-in-the-woods. Quantitative approaches were used to determine Informant Consensus Factor (ICF) and Fidelity level (FL) values. Statistical tests were used to compare the indigenous knowledge on medicinal plants among different informant categories.

Results

A total of 135 medicinal plant species belonging to 128 genera and 71 botanical families were reported to treat human diseases in the District. Families Asteraceae (12 species, 9%) and Fabaceae (10, 7.4%) were found to be best represented in the area. About 44% of preparations were reported to be obtained from roots. Significant difference (P?<?0.05) was observed on the mean number of medicinal plants reported by groups of respondents compared within age, literacy level and experience parameters. Highest ICF values were recorded for gastro-intestinal & parasitic and dermatological disease categories (0.70 each) indicating best agreement among informants knowledge on medicinal plants used to treat aliments in these categories. Highest fidelity level values were recorded for Zehneria scabra (95%) and Hagenia abyssinica (93.75%) showing conformity of knowledge on species of best healing potential. Podocarpus falcatus was ranked first in a direct matrix ranking exercise of multipurpose medicinal plants. The output of preference ranking exercise indicated that Olea europaea subsp. cuspidata was the most preferred species to treat atopic eczema.

Conclusion

The study revealed that Ankober District is rich in medicinal plant diversity and associated indigenous knowledge. However, anthropogenic factors coupled with acculturation and very poor conservation efforts threaten medicinal plant survival in the area. Promoting a complementary in situ and ex situ conservation strategy for medicinal plants of the District is highly recommended.

     

An ethnobotanical study of medicinal plants used in Kilte Awulaelo District,Tigray Region of Ethiopia

Background

The Ethiopian people have been dependent on traditional medicine, mainly medicinal plants, from time immemorial for control of human and animal health problems, and they still remain to be largely dependent on the practice. The purpose of the current study was to conduct ethnobotanical study to document medicinal plants used to treat diseases of human and domestic animals in Kilte Awulaelo District in the Tigray Region of Ethiopia.

Methods

Ethnobotanical data were collected between July and September 2011 through semi-structured interviews, ranking exercises and field observations. For the interviews, 72 knowledgeable informants were sampled using purposive sampling method. For the different ranking exercises, key informants were identified with the help of elders and local administrators from informants that were already involved in the interviews.

Results

The study revealed 114 medicinal plant species belonging to 100 genera and 53 families. The plants were used to treat 47 human and 19 livestock diseases. Of the species, the majority (74%) were obtained from the wild. Herbs were the most utilized plants, accounting for 44% of the species, followed by shrubs (29%). Leaf was the most commonly used plant part accounting for 42.98% of the plants, followed by roots (25.73%). Preference ranking exercise on selected plants used against abdominal pain indicated the highest preference of people for Solanum marginatum. Direct matrix ranking showed Cordia africana as the most preferred multipurpose plant in the community. Preference ranking of selected scarce medicinal plants indicated Myrica salicifolia as the most scarce species, followed by Boscia salicifolia and Acokanthera schimperi. According to priority ranking, drought was identified as the most destructive factor of medicinal plants, followed by overgrazing and firewood collection.

Conclusion

Medicinal plants are still playing significant role in the management of various human and livestock diseases in the study area with herbs taking the lead in the number of plants used in the preparation of remedies, which may be an indication of their relatively better abundance as compared to other life forms. Recurrent drought was reported to have seriously threatened medicinal plant resources in the District. Awareness is thus needed be raised among local people on sustainable utilization and management of plant resources. Ex situ and in situ conservation measures should be taken to protect the medicinal plants of the District from further destruction and special attention should be given to the medicinal plants that were indicated by preference ranking exercise as the most threatened ones.

Ethnobotanical survey of plants used in Afyonkarahisar-Turkey

Background

The traditional knowledge about plants and their uses in Turkey is disappearing in recent years because the new generations of villagers migrate to big cities for a better life. Afyonkarahisar located at the intersection of roads and phytogeographical regions (Mediterranean, Iran-Turan, and Euro-Siberian) has more than 2500 plant species. This richness of plant diversity promotes the indigenous commuity for the traditional use of wild plants. The aim of the study is to show wild plants’ ethnobotanical usages associated with medicinal, food, fodder, and household goods in 31 settlements within the boundaries of Afyonkarahisar province.

Methods

The ethnobotanical data were collected from 46 informants by means of semi-structured interviews from 2012 to 2014. Ethnobotanical uses of plants of the study area were conducted in the vicinity of Afyonkarahisar (5 districts, 8 towns, 15 villages, and 3 neighborhood centers).

Results

One hundred and thirty plant taxa belonging to 39 families were recorded and collected. Hundred and seventy-eight different uses of these plants were documented and used generally for medicinal (84), food (68), fodder (16), household goods (3), dyes (3), handicrafts (3) and religious (1).

Conclusion

This study provides interesting uses of plants in the local community of Afyonkarahisar and its surrounding area, in what purpose they make use of plants, how they make use of them and obtained results will contribute to economy of villagers. Since the local people, especially in villages, are poor and do not have health care, they use the plants to treat illnesses, food, fodder, household goods and other uses (evil eye). Also this study will light the way for posterity for next generations.

     

Ethnobotanical significance of medicinal plants: Beta-amyloid and tau aggregation inhibitors against Alzheimer's disease

Among the various neurodegenerative disorders, Alzheimer's disease (AD) is identified as one of primary causes of dementia in the elderly, which progresses slowly leading to cognitive decline and ability to function independently. Although various pathological mechanisms have been proposed, the exact mechanism is not yet elucidated. Numerous processes such as old age, mitochondrial dysfunction, and genetics lead to the aggregation of beta-amyloid (Aβ) as amyloid plaques and tau proteins as neurofibrillary tangles in the neurons leading to their death and destruction, finally leading to AD. The current treatment measures can only temporarily improve the symptoms, slowing cognitive decline without any effect on AD pathology for better therapeutic effect. Furthermore, the high failure rates of a number of drugs during clinical trials due to their side effects has led the researchers to focus on alternative sources for drug development. As natural ingredients were considered the primary line of treatment in the olden days, and as several medicinal plant products are also proven as effective AD targets, it will be wise to investigate those with significant ethnobotanical value as potential neuroprotectives, nootropics or memory boosters. Throughout the study, propanoids, glycosides, iridoids, carotenoids and flavonoids that show potential anti-inflammatory, antioxidant, and anti-cholinesterase were also found to be inhibitors of Aβ and tau aggregation, where Saikosaponin C, Fisetin, and Morin can act as dual inhibitors. The review provides an insight in the need for proper and complete scientific evaluation of these ethnobotanically useful medicinal plants to be identified as potential leads in AD therapy.

Ethnobotanical and antibacterial study of Primula plants traditionally used in the indigenous communities of Western Himalaya,Pakistan

BackgroundThe upper belt of Azad Kashmir is a hilly, mountainous, and remote area where the indigenous communities mainly believe in traditional medicines for the treatment of different ailments. This study aimed to conserve scientifically and culturally important medicinal knowledge of Primula species in Azad Kashmir, Western Himalaya, Pakistan. The additional objective was to evaluate the antibacterial activity of these plants against pathogenic bacteria.MethodsThe ethnomedicinal data of Primula species was explored by conducting structured interviews with 40 informants of the study area, especially asking about the medicinal uses of Primula species. The indigenously used Primula species were further analyzed for their antibacterial activity against both gram-positive and gram-negative bacteria by using disc diffusion assay supplemented with a more robust minimum inhibitory concentration assay.ResultsEthnomedicinal data revealed that indigenous communities living in upper regions of Azad Kashmir use 5 Primula species for the treatment of various disorders. The highly cited disease category was ophthalmic disorders. P. denticulata and P. macrophylla were the most cited plant species with higher use reports such as 104 and 93, respectively. One or more extracts of different parts of Primula species showed a noteworthy antibacterial activity against one or more tested bacteria.ConclusionThis study provides novel information regarding several categories of traditional uses and antibacterial activity of Primula species in Azad Kashmir, Western Himalaya. The need for novel and more effective drugs derived from natural products is more important than ever, making future studies on herbal remedies both justified and urgently required.     

Ethnobotanical study on pesticidal plants used in Southwest Nagaland,India for the development of eco-friendly pest control system

BackgroundManagement of crop pests has been a great challenge around the world. In this study, the plants that are traditionally used as pesticides in southwest Nagaland were identified and documented. Pesticidal plants are an effective alternative to harmful synthetic pesticides and they may help in the formulation of a diverse group of organic pesticides.MethodsInformation on pesticidal plants was obtained through field study and semi-structured interviews. 360 informants from 24 villages were interviewed. Data were analyzed through quantitative tools – use value (UV), informants consensus factor (ICF), fidelity level (FL), and family use value (FUV). Phytochemical analysis of selected plants was done.ResultsIn total, 113 species representing 104 genera and 46 families were documented as pesticidal plants. Asteraceae was the most preferred family as a pesticide with 17 species. Herbs were recorded for 43% of use which was the highest among the habitats. Out of 113 species, 105 species were used as insecticides. Leaf (57.3%; 98 species) was the highest use plant part as a source of pesticides. The highest UV was recorded for Nicotiana tabacum (0.46) with 165 use reports. The ICF value was recorded from 0.96 to 0.97. In regards to FL, several potential pesticidal plants including Azadirachta indica, N. tabacum, Capsicum frutescens, and Curcuma longa were identified with 100% FL each. Phytochemical analysis showed the presence of secondary metabolites like alkaloid, flavonoid, phenol, saponin, tannin, and terpenoid.ConclusionInhabited by a diverse tribal population, the southwest part of Nagaland is a hub of ethnobotanical knowledge. The present study was the first quantitative survey on the plants used as pesticides by the tribal communities of southwest Nagaland and would help modern pharmacology immensely in formulating organic pesticides.     

An ethnobotanical study of medicinal plants used by local people in the lowlands of Konta Special Woreda, southern nations, nationalities and peoples regional state, Ethiopia

Background

Research was carried out in Konta Special Woreda (District); it is a remote area with lack of infrastructure like road to make any research activities in the area. Therefore, this research was conducted to investigate medicinal plants of the Konta people and to document the local knowledge before environmental and cultural changes deplete the resources.

Methods

The information was collected between October 2006 and February 2007. Interview-based field study constituted the main data collection method in which the gathering, preparation, use, previous and current status and cultivation practices were systematically investigated. The abundance, taxonomic diversity and distribution of medicinal plants were studied using ecological approach.

Results

A total of 120 species, grouped within 100 genera and 47 families that are used in traditional medical practices were identified and studied. The Fabaceae and Lamiaceae were the most commonly reported medicinal plants with 16 (13.3%) and 14 (12%) species, respectively. 25.4% of the total medicinal plants are collected from homegardens and the rest (74.6%) are collected from wild habitats. Of the total number of medicinal plants, 108 species (90%) were used to treat human ailments, 6 (5%) for livestock diseases and the remaining 6 (5%) were used to treat both human and livestock health problems. The major threats to medicinal plants reported include harvesting medicinal plants for firewood (24.8%) followed by fire (22.3%) and construction (19%). Of the four plant communities identified in the wild, more medicinal plant species (34) were found in community type-4 (Hyparrhenia cymbaria-Erythrina abyssinica community), which accounted for 61.8%.

Conclusion

Konta Special Woreda is an important area for medicinal plants and associated local knowledge; the natural vegetation being the most important reservoir for the majority of the medicinal plants. Environmental and cultural changes are in the process of threatening the resources and this signals the need for serious efforts to create public awareness so that measures are taken to conserve the medicinal plants in the natural ecosystems and other suitable environments.     

Ethnobotanical investigation of 'wild' food plants used by rice farmers in Kalasin, Northeast Thailand

This paper reports on the plant use of laypeople of the Oromo in Southern Ethiopia. The Oromo in Bale had names/uses for 294 species in comparison to 230 species documented in the lower reaches of the Bale area. Only 13 species was used for veterinary purposes, or as human medicine (46). Plant medicine served mostly to treat common everyday ailments such as stomach problems and diarrhea, for wound treatment and as toothbrush-sticks, as anthelmintic, for skin infections and to treat sore muscles and. Interestingly, 9 species were used to treat spiritual ailments and to expel demons. In most cases of medicinal applications the leaves or roots were employed. Traditional plant knowledge has clearly declined in a large part of the research area. Western style health care services as provided by governments and NGOs, in particular in rural areas, seem to have contributed to a decline in traditional knowledge, in part because the local population simply regards western medicine as more effective and safer.     

Antibacterial activity of selected medicinal plants of northwest Pakistan traditionally used against mastitis in livestock

The present study aimed to investigate the efficacy of traditionally used anti-mastitis plants (Allium sativum, Bunium persicum, Oryza sativa and Triticum aestivum) in northwest Pakistan against bacterial pathogens. Selected plants were phytochemically screened for Alkaloids, Flavonoids, and Saponins and checked for in vitro antibacterial activity at concentration of 50 mg/ml against S. aureus, E. coli and K. pneumoniae by agar well diffusion method. Minimum inhibitory concentration and minimum bactericidal concentration was determined against multidrug resistant bacteria using tube dilution method. All extracts were found to significantly inhibit (p < 0.01, p < 0.05) the activity against bacterial strains examined. Among phytochemicals, alkaloids of all tested antimastitis plants produced significantly higher inhibition zones against bacteria. The minimum inhibitory concentration and minimum bactericidal concentration of phytochemicals and crude methanolic extracts against tested bacterial strains ranged between 12.5–50 mg/ml and 25–50 mg/ml, respectively. Medicinal plants traditionally used against mastitis are therapeutically active against bacterial pathogens. A. sativum and B. persicum were found to be potential candidate species for the development of novel veterinary drugs with low cost and fewer side effects.
