Investigators at Debre Markos University and Addis Ababa University conducted an ethnopharmacologic survey of medicinal plants used to treat human diseases by traditional medical practitioners in Dega Damot district, in the Amhara region of northwestern Ethiopia.

Writing in BMC Research Notes, the authors note that although about 90% of the population in the district relies on traditional health products for primary health care, no studies have previously been conducted on the use and practice of traditional medicine in the region.

Working with 45 traditional medical practitioners chosen with the help of community leaders and local authorities, the team documented 60 species of medicinal plants used for the treatment of 55 disorders including evil eye, malaria, wounds, peptic ulcers, and rabies. Important medicinal plant species included Allium sativum (for evil eye), Phytolacca dodecandra (for rabies), and Croton macrostachyus (for malaria).

The authors note that drought, overgrazing, and firewood collection are among the threats to sustainability of medicinal plants in the area:

“According to the results of this study, drought is the most serious threat to medicinal plants followed by overgrazing. This is in conformity with the survey conducted in Gemad district and Kilte Awulalo, but according to a study done in Loma and Gena Bosa, agricultural expansion was the major threat followed by timber and other demands. This is probably due to the increasing number of population. However, study done in Hawasa city indicated urbanization as the most serious threat for medicinal plants.”

Investigators at the University of Florida, Mississippi State University, Ege University, and Dokuz Eylul University conducted an ethnobotanical study in Midyat (Mardin Province), in southeastern Turkey, to document uses of local plants and to make an inventory of uncommon plants used ethnobotanically in the area.

Writing in the Journal of Ethnobiology and Ethnomedicine, the authors describe Midyat’s role as a millennia-old meeting place of cultures:

“Midyat, formerly known as Matiat, was built in the ninth century BCE by Syriac settlers, and a record of it was found written on Assyrian tablets. The Silk Road is an historic route for overland travelers. The town of Mardin in south-eastern Turkey is an attraction of the Silk Road. The Silk Road is more than just a trade route linking Asia and Europe; it is a display of cultures, ethnicities and religions that have settled in the region, and presents 2000 years of historical and cultural wealth. From east to west, it was used in transporting silk, porcelain, paper, spices, and jewels for cultural exchange between continents.”

As far as the authors know, this is the first ethnobotanical study conducted in Midyat.

“Ethnobotanical studies have been on the increase in many regions of Turkey. In Midyat (Mardin Province, Turkey), people benefit from the diversity of flora by using plants as a rich source of medicine. Medicinal plants were used by Anatolian cultures, hence the accumulation of large amounts of remarkable medicinal folk knowledge in the region. Although there are some studies in eastern Anatolia, the southeast region of Anatolia is still a poor area in terms of ethnobotany studies. Midyat has a great diversity of plant species given its climatic variation and different ecological habitats. The different ways of life and rich culture in the districts of Midyat have created diverse ethnobotanical usages. One of the oldest traditional plant usages is medicinal, which depends on knowledge and practical experience of using these natural materials.”

Among the 92 taxa of traditional plants documented, 35% were used for medical purposes. These included Alcea setosa (cough and flu cure, wound healing, labor pain); Alcea striata (cough and flu cure, wound healing); Anthemis cotula (treatment for stomachaches and flu); Malva neglecta (stomachache cure, weight loss, labor pain, kidney diseases, diuretic); Matricaria aurea (cough and flu cure, stomachache cure, bronchial cure, cardialgia); Salvia multicaulis (wound healing, flu and cough cure, labor pain, anti-inflammatory, antidote); and Teucrium polium (stomachache cure).

In their conclusion, the authors note the importance of conservation, both of the plant species and of ethnobotanical knowledge in the region.

“Our study indicates the importance to document not only medicinal plants, but also edible plants or plants used for fodder, fuel, dyes, and other purposes…. The conservation of this extensive knowledge is crucial, particularly because knowledge is no longer being passed down from older to younger generations. The use of endemic plants is relatively rare, but Centaurea stapfiana, Thymbra sintenisii are used extensively, and their conservation status is compromised by their use as food and fodder plants. Additionally, our findings suggested that Midyat and its vicinity might represent a beginning point for further comparative cross-cultural ethnobotany that can contribute to enhancing the current knowledge of folk medicinal plants and lead to conservation plans for protecting rare plant species.”

Zhemgang District, Bhutan

Investigators at James Cook University, Wangbama Central School, and the Bhutan Ministry of Health conducted an ethnobotanical study to identify subtropical medicinal plants from the Lower Kheng region in the Zhemgang District of Bhutan, where Bhutanese Sowa Rigpa medicine has been practiced for centuries:

“In Bhutan, while some traditional physicians argue that Sowa Rigpa originated in the 8th century CE with the advent of Mahayana Buddhism, many scholars believe that it was only in 1616 that Lama Zhabdrung Nawang Namgyal laid written foundation to this medical system. The Bhutanese Sowa Rigpa medicine (BSM) belong to the larger corpus of the Tibetan scholarly medical (TSM) system, which was derived from Chinese Traditional Medicine, Indian Ayurvedic Medicine, Greco-Roman medicine, and the Persian medicine (Galenos). However, the country’s culture, tradition, local medical practices, geography, and vegetation influenced the way BSM evolved independently over many centuries, making it specific to Bhutan.”

The authors note that theirs is the first ethnobotanical study to be conducted in the Lower Kheng region:

“The criteria and reasons for choosing these areas as our ethnobotanical study areas were: (1) there was unsubstantiated/anecdotal claim about the lush growth of LAMP in the region; (2) no ethnobotanical study has been conducted in this region to date; and (3) Lower Kheng people are poor and their engagement in the medicinal plants collection, cultivation, and marketing programs could help them generate cash income.”

Aquilaria malaccensis

The research team identified 61 medicinal plants, 30 of which were found in abundance, including Terminalia chebula, Terminalia bellirica, and Phyllanthus emblica, together known as “King of Medicine” (Mengi-Pawo) or “Three Powerful Medicines.” Another species, Aquilaria malaccensis, which is considered rare in other parts of the world, was found to be abundantly cultivated in household and community gardens throughout the region. More than 20 species were found in all the villages surveyed. These included Bombax ceiba, Canarium strictum, Cassia tora, Cautleya spicata, Choerospondias axillaris, Cinnamomum impressinervium, Erythrina arborescens, Justicia adhatoda, Knema tenuinervia, Mucuna imbricata, Otochilus lancilabius, Phlogacanthus thyrsiformis, Piper mullesua, Rhus chinensis, Stephania glabra, Symplocos sumuntia, and Tinospora cordifolia.

In their conclusion, the authors recommend further work toward sustainable development and commercialization of the region’s medicinal plants:

“Many plant species have commercial and economic values. While MSP is currently viewed as the sole domestic market for these medicinal plants, many species have international significance (especially applicable to countries that practice Tibetan Sowa Rigpa medicine and Indian Ayurvedic medicine including India, Nepal, Mongolia, Tibet, Europe, and Northern America). The communities would largely benefit by domesticating or cultivating them in the household gardens or as cash crops in their family orchards. This medicinal plants program has the potential to alleviate poverty in these three Gewog communities and could enhance the happiness, wellbeing and development in Bhutan. Since the communities consume 28 medicinal plants as food grains, spices, herbs, and fruits, it can be assumed that the local people are also deriving health benefits.”

Investigators at the Universidade Federal de Juiz de Fora, University of Hawai’i at Mānoa, Centro de Ensino Superior de Juiz de Fora, Universidade Federal Fluminense, and Universidade Federal de São Paulo conducted an ethnobotanical and ecological survey to evaluate the uses, knowledge, and conservation status of plants in two Quilombolas (descendants of slaves of African origin) communities in the Atlantic rainforest of Brazil: São Sebastião da Boa Vista and São Bento Abade in the state of Minas Gerais.

Writing in PLoS One, the team describes Brazil’s Atlantic rainforest as one of the world’s most biodiverse and most threatened biomes:

“Brazil is one of the world’s megadiverse countries, and the Atlantic rainforest, which stretches from the northeastern to the southern regions of the country, is the most biodiverse biome of Brazil, with up to 476 plant species found in one hectare. Unfortunately, the Atlantic rainforest is also one of the most threatened forest types in the world, with nearly 90% of its original area devastated. As is the case with the majority of Brazilian protected areas, the Atlantic Rainforest is also home to many traditional communities–those that have lived in one location for a long period of time, such as the Quilombolas. According to the Living Report of World Wide Fund for Nature, 90% of tropical forests worldwide are not under formal protection and millions of people living both inside and outside of reserves rely on their resources.”

Through interviews with local Quilombolas experts, the team documented 212 ethnobotanically significant species in São Sebastião da Boa Vista (including 105 native species) and 221 in São Bento Abade (96 native species).

Medicinal and technological uses were the most important uses in both communities. Some of the most culturally important medicinal species were also among the most vulnerable, among them Dalbergia hortensis and Sparattosperma leucanthum.

In their conclusion, the authors strongly recommend “development of a sustainable management plan that considers local knowledge about management and use of plants”:

“These data illustrate the rich ethnobotanical knowledge and heritage of the communities. However, our results also suggest that more than 50% of local useful species in both communities (those ranked in Category 1 for conservation priority) may be at risk if there are no plans for the management and replanting of them. Of these plants, Dalbergia hortensis is a special conservation priority because of its great cultural significance. Other species such Sparattosperma leucanthum, Lygodium volubile in SSBV, Cecropia glaziovii in SB, and Croton urucurana in both communities rank high for cultural significance and conservation priority. Based on our results, the development of a sustainable management plan that considers local knowledge about management and use of plants is essential. Developing programs to increase populations of those species at risk, including agroforestry programs can help meet the needs of producing culturally important species and of biological conservation. It is urgent that the government demarcate Quilombolas land for cultural maintenance, quality of life and preservation of nature.”

Researchers from the University of Bologna and MUSE (Museo delle Scienze) investigated and recorded traditional knowledge about the use of wild and cultivated plants in villages adjacent to Udzungwa Mountains National Park in Tanzania’s Kilombero River floodplain.

Writing in the Journal of Ethnobiology and Ethnomedicine, the team reports findings from interviews with ten traditional local healers selected with the collaboration of Associazione Mazingira, a group affiliated with MUSE that runs environmental education projects in the area and maintains close contact with the local people.

Cajanus cajan

The traditional healers described 196 plant species used for ethnomedicinal and other everyday purposes like food, fibers, and timber, 118 of which the team could classify botanically. Species highly cited for medicinal purposes included Cajanus cajan (teeth and gums, otitis); Hibiscus surattensis (eye diseases, gastrointestinal diseases); Kigelia africana (pain and inflammation, gastrointestinal diseases); and Vitex doniana (weakness and fainting).

The authors note that forests in Tanzania are under severe threat, with deforestation in the Kilombero Valley in particular caused by competition for land by agriculture, teak and eucalyptus plantations, and charcoal production. In contrast to the lowlands, forests in the neighboring Udzungwa Mountains are protected along the entire range, increasingly restricting the access of local people to harvesting areas, to the detriment of ethnobotanical knowledge in the region:

“For years, local healers could bypass the restrictions for access to National Parks, but given the increasingly strict rules, they have lately been forced to change their places of collection with a serious impact on everyday life. In fact, the knowledge and experience of each traditional healer are deeply linked to the place where he/she learned and practiced plant collection over the years. There are now few forest areas in Kilombero Valley that can provide therapeutic plants. These are located far from the villages, and some of the collection methods, such as decortication [removal of a plant’s outer layer], could be extremely impactful when carried out in small areas, making the plants unusable after a few years….

“Since the founding of Udzungwa Mountains National Park, more than 24 years ago, there has been a depletion of the traditional medical culture, due to the forced abbandonement of familiar areas of collection, as well as the progressively more difficult transmission of knowledge to and training of young healers. Finally, the cost of traditional medicine is now starting to grow, causing a significant problem for people who have always relied on this method for their healthcare.”

The creation and subsequent management of the Udzungwa Mountains National Park has had the unintended consequence of reducing collection areas for plant species essential to the lives of people living in the Kilombero Valley, intensifying the harvesting pressure on the few remaining areas of unprotected forest and endangering ethnobotanical culture and knowledge developed over many generations:

“Harvesting practices like root excavation and stem decortication are causing a progressive depletion of many medicinal plant species. In addition, deforestation makes medicinal species harvesting areas increasingly scarce, forcing many local healers to abandon the practice. In the light of these facts, it is essential, in the immediate future, to educate traditional healers as well as common people to the sustainable use of the surrounding natural heritage. It seems also necessary to provide the populations with additional means to increase the forested areas, such as the distribution of seedlings for biomass production. Although some efforts have already been made in the studied territory, and in spite of a firm tradition in Tanzania of community-based forest conservation, the situation remains critical and the state of unprotected forests near these villages is deteriorating year after year. This situation, if not quickly reversed, may lead to an unprecedented environmental crisis and to the loss of much of the traditional ethnobotanical culture. In this context, the present study wishes to contribute, at least to some ex[t]ent, to preserving the knowledge present in the investigated populations, still deeply connected to nature, and to passing down this unevaluable tradition to future generations.”

In passing, the authors state that “no actions have been taken to solve problems related to plant gathering practices.” Might this area of neglect motivate some new initiatives to solve a perennial problem, how best to balance the aims of forest conservation with the rights and needs of indigenous people?

Investigators at Universidad Técnica Particular de Loja conducted an ethnobotanical survey in the Loja Province of southern Ecuador to learn about the use of medicinal plants by Hampiyachakkuna community healers treating the indigenous Saraguro population in San Lucas Parish.

Writing in the journal BioMed Research International, authors José M. Andrade, Hernán Lucero Mosquera, and Chabaco Armijos note that only a few ethnobotanical studies have reported on the use of plants in the Saraguro region and that a thorough documentation of medicinal plants used by Saraguro healers has not been done prior to this investigation. They describe an urgent need to document and preserve this cultural knowledge:

“The Saraguros are one of the best-organized ethnical groups in Ecuador and have conserved many aspects of their ancient culture and traditions for centuries. They demonstrate the latter by preserving their typical dressing, language, religion, gastronomy, architecture, social habits, and medical practices. Among their medical practice traditions, this ethnic group is known for the use of medicinal plants in their own health care system. In fact, the use of these plants as therapeutic agents is an important feature of traditional indigenous medicine and is still practiced within the Saraguro community. In particular, the Saraguros are highly recognized for the development of optimization techniques that help them select natural/plant resources to be used in their health care practices.”

The team carried out their research on several field visits, during which they interviewed four healers from the Saraguro community (a Wachakhampiyachak [midwife], a Yurakhampiyachak [herbalist], a Kakuyhampiyachak [bone-healer], and a Rikuyhampiyachak [visionary]) regarding the medicinal plants they used in their practices. Notably, while the healers are highly trusted and recognized as effective by the community, they are also well integrated into the region’s allopathic health care system and readily transfer a patient to a health center or hospital when they detect serious conditions.

Working with the healers, the investigators documented the existence of 183 medicinal plant species used in 75 different curative therapies, including nervous system treatments, cold treatments, infection treatments, general malaise treatments, inflammatory treatments of the liver and kidneys, and “mythological” treatments (for diseases determined to be of a supernatural nature).

Salvia leucocephala

The team documented thirteen medicinal plants endemic to the region: Achyrocline hallii (sacha algodón); Ageratina dendroides (pegac chilca); Bejaria subsessilis (pena de cerro); Brachyotum scandens (sarcillo sacha); Dendrophthora fastigiata (suelda pequeña); Diplostephium juniperinum (monte de baño); Diplostephium oblanceolatum (chuquir agua); Fuchsia hypoleuca (sacha pena); Huperzia austroecuadorica (wuaminga verde pequeño); Lepechinia paniculata (shallshón); Phoradendron parietarioides (suelda grande); Salvia leucocephala (sp flor morado); Siphocampylus scandens (pena rojo de monte). Most of these plants are either vulnerable or endangered, due primarily to habitat loss.

In their conclusion, the authors stress the importance of preservation:

“This research conducted in collaboration with the members of the native Saraguro community constitutes a baseline study to help promote the preservation of this ancient medicinal knowledge by a thorough documentation of the natural resources and processing methods used. Moreover, we hope the results of this study motivate young generations to envision the potential of the use and application of traditional knowledge in medicinal practices. Finally, this scientific research and the results here reported aim at preserving and enhancing, as much as possible, a culture of the practice of natural ancient medicinal science, while preserving the environment, nature, life, culture, and sovereignty of the Saraguro people.”

Investigators at Temple University and Universidad Nacional de Chimborazo conducted an ethnobotanical/phytotherapy study in cooperation with local ancestral healers to document medicinal plants used in traditional herbal medicine in the Province of Chimborazo, Ecuador.

Writing in the African Journal of Traditional, Complementary, and Alternative Medicines, the authors note the paucity of published ethnomedicinal studies of this region.

“The Andean region of Ecuador has witnessed a marked expansion of nature conservation initiatives. Specifically, the province of Chimborazo, with 59.3% of indigenous population living in rural areas, is considered a millenarian and intercultural province, where multiples cultures and ethnic groups coexist. It owns a rich cultural heritage, with diverse life styles in rural communities. Particularly, in the urban marginal and rural areas of Chimborazo, the native traditional medicine covers the prevention, promotion and cure health services. For that reason, several initiatives have been carried out in order to strengthen the knowledge and wisdom of the ancestral healers of the region. Although there are many studies about medicinal plants in the regions of Quito, Buitrón, Cotopaxi and Imbabura, the phyto studies on Chimborazo province are really limited.”

Urtica dioica

The team worked with 84 traditional healers, who identified a total of 153 different medicinal plants used to treat 179 different symptoms or illnesses. Ten of the most-used plants were selected for additional study: chamomile (Matricaria recutita); nettle (Urtica dioica); ragweed (Ambrosia arborescens); rue (Ruta graveolens); eucalyptus (Eucalyptus obliqua); plantain (Plantago major), feverfew (Tanacetum parthenium); borage (Borago officinalis); field horsetail (Equisetum arvense); and mallow (Malva sylvestris).

The traditional healers will be kept informed of ongoing research, as they indicated an interest in knowing any new findings about active ingredients and other properties of the plants used in their ancestral medicine.

Researchers from the University of Nairobi conducted an ethnobotanical survey to document plants used in the management of malaria among Luhya people living in Kakamega County, Kenya. Two of the species, Rumex steudelii and Phyllanthus sepialis, have not previously been reported as malaria remedies.

In a paper published in the Journal of Ethnopharmacology, the authors describe the need for investigation of antimalarial botanical medicines used by the people of this region:

“In Kenya, 80% of the population is at risk of contracting [malaria]. Pregnant mothers and children under five years are the most affected by this disease. Antimalarial drug resistance poses a major threat in the fight against malaria necessitating continuous search for new antimalarial drugs. Due to inadequate and inaccessible health facilities, majority of people living in rural communities heavily depend on traditional medicine which involves the use of medicinal plants for the management of malaria. Most of these indigenous knowledge is undocumented and risks being lost yet such information could be useful in the search of new antimalarial agents.”

Rotheca myricoides

Working with traditional medicine practitioners and other caregivers, the team documented 42 plant species used in the management of malaria, including Melia azedarach, Aloe spp, Ajuga integrifolia, Vernonia amygdalina, Rotheca myricoides, Fuerstia africana, Zanthoxylum gilletii, Leucas calostachys, Clerodendrum johnstonii, and Physalis peruviana.

Two of the species identified by the team have not previously been reported as treatments for malaria: Rumex steudelii and Phyllanthus sepialis. With two exceptions (Clerodendrum johnstonii and Physalis peruviana), the rest have been tested in the laboratory for antiplasmodial activities. Antiplasmodial compounds have been isolated from fewer than half of the plants so far.

The authors conclude with a call for conservation, both of traditional ethnomedicinal knowledge and of the medicinal plants themselves. They note that botanical medicines used for malaria are mainly obtained from the wild and that those which are cultivated are done so because they are not easily available in the wild (e.g., introduced plants) or face extinction (e.g., Ajuga integrifolia).

In Slovenia, A Tradition of Using Media to Advance Ethnomedicinal Knowledge

Share

Folk use of medicinal plants in Karst and Gorjanci, Slovenia

Lumpert M, Kreft S
J Ethnobiol Ethnomed. 2017 Feb 23;13(1):16
PubMed Central: PMC5324297

Researchers from the University of Ljubljana conducted an ethnobotanical study in two remote Slovenian villages, Karst and Gorjanci.

Writing in the Journal of Ethnobiology and Ethnomedicine, Mateja Lumpert and Samo Kreft note that only a few rigorous ethnobotanical studies have been conducted in Slovenia:

“The use of plants has been scarcely investigated in Slovenia, and only a few ethnobotanical studies have been conducted. The Karst region is a limestone plateau in southwestern Slovenia that continues on the Italian side of the border. The Italian part of the Karst region, also known as Trieste Karst, was included in an ethnobotanical study of the Venezia Giulia region in 1988, and a list of 59 plants that were used in Trieste Karst was reported. Guštin Grilanc investigated the folk herbalist tradition in both the Italian and Slovenian parts of the Karst region and published a list of 124 plants used for healing, food, toys, superstitions, and folk traditions with short descriptions; however, the methodology of the work was not described, and only a detailed list of informants was given. Gorjanci is a mountain range in southeastern Slovenia that runs southwest to northeast along the Croatian border. From 1950 to 1983, ethnographic researchers collected testimonials on the natural and magical treatment of the people in Dolenjska and Bela Krajina, two regions where Gorjanci is located. Makarovič analyzed the collected testimonials and concluded that the ethnographers’ notes contained random and generalized data on knowledge about natural medicines and magical practices; those data were collected unsystematically and were incomplete. As a result, this analysis provided a very rough estimation of the use of medicinal plants.”

Working with local herbalists, Lumpert and Kreft documented 78 medicinal plants used in Karst and 82 in Gorjanci.

Sambucus nigra

Sambucus nigra was the most frequently reported plant in both villages. Other frequently reported plants were Rosa spp., Salvia officinalis, Thymus serpyllum, Mentha spp., Melissa officinalis, Matricaria chamomilla, and Tilia spp. in Karst and Achillea millefolium, Tilia spp., Matricaria chamomilla, Urtica dioica, Hypericum perforatum, Rosa spp., Centaurium spp., and Vaccinium myrtillus in Gorjanci.

The authors note a long tradition in Slovenia of herbalists using written sources to advance ethnomedicinal knowledge:

Title page of Tabernaemontanus "Neuw Vollkommentlich Kreuterbuch", 1625

“In Slovenia, knowledge about plants is transmitted from generation to generation and is also influenced by written sources. The beginning of this practice goes back to Comments of Dioscorides written by Pietro Andrea Mattioli. He lived and worked from 1540 to 1554 in Gorica, a town in northeastern Italy populated by a Slovene-speaking minority, and he was the first to describe plants of Slovenian flora. In the 18th and 19th centuries, folk healers in Slovenian ethnic territory used folk medicine manuscripts, which were translations of mostly German medicine and veterinary books, especially herbals (or Kräuterbücher) from the 16th century and the beginning of the 17th century. Most manuscripts were translations of Gart der Gesundheit (1485), Kreutterbuch by Pietro Andrea Mattioli (1590), Neu Vollkommenes Kräuter-Buch by Pietro Andrea Mattioli (1678), Vollständiges Kräuterbuch by Adam Lonicer (1557), and Neu Vollkomentlich Kreuterbuch by Jakob Tabernaemontanus (1613). Later, the translated books were manually transcribed many times, and the transcribers added their own observations to the manuscripts. In the second half of the 19th century, the first original (non-translated) Slovenian works about medicinal plants were published, and manuals for the wild collection, drying and use of Slovenian medicinal plants were issued later. Throughout the 20th century, there was steady growth of published books about medicinal plants; some of them were original Slovenian works, and some were translations from foreign authors; most were written by pharmacists and only some by folk healers.”

With an important and widespread practice of plant collection combined with a nearly 100% literacy rate, Slovenia offers a rare, perhaps unique, perspective on the evolution of ethnomedicinal knowledge in literate societies, where books, television, journals, and the internet join oral transmission between individuals, potentially to bring very rapid cultural change.

Investigators from Jawaharlal Nehru University and Indira Gandhi National Forest Academy conducted an ethnobotanical study to find plants with antimalarial activities used by local people in the Gorakhpur, Kushinagar, and Maharajganj districts of eastern Uttar Pradesh.

The team documented 51 plants used for the treatment of malaria, including Adhatoda vasica, Cassia fistula, and Swertia chirata.

The authors note that many important medicinal plants in the area are becoming rare and some of them are critically endangered because of overexploitation, loss of water reservoirs, and changes in land use.

From the conclusion:

“The work carried out revealed the plants recorded are highly valuable for antimalarial application and in future, bio-prospecting projects can be further initiated for sustainable harvesting towards developing antimalarial drug for curing malaria at large. It would help researchers to find out suitable lead molecules with antimalarial activity towards drug discovery. The study provides ample ground to believe that the traditional medicinal system practice using native medicinal plants is alive and well functioning in the selected area. Many communities use antimalarial plant parts and whole plant for their primary healthcare. It is primarily due to lack of modern medicines, medications, self-reliance on herbs, poor economic condition and more importantly faiths in TK System. The treatment of malaria with plants and plant parts causes little or no side effects and also it is very cheap and affordable. Some plants are nearly extinct in the region, the reason being change in land use pattern and shrinking of water bodies along with over harvesting of herbs. The bio-depletion of these antimalarial plants is due to the burgeoning population and unscientific management of the natural resources.”
