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.”

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.”

Bhutan Finds Alternative Source of Medicinal Plants to Ease Pressure from Commercial Harvesting

Medicinal plants of Dagala region in Bhutan: their diversity, distribution, uses and economic potential

Wangchuk P, Namgay K, Gayleg K, Dorji Y
J Ethnobiol Ethnomed. 2016 Jun 24;12(1):28
PubMed Central: PMC4921017

Bhutan’s Ministry of Agriculture and Forests and Ministry of Health conducted an ethnobotanical survey to determine if the Dagala village block (gewog) might serve as an alternative collection site for the state-run Menjong Sorig Pharmaceuticals, which manufactures plant-based medicines for traditional g.so-ba-rig-pa hospitals in Bhutan.

Writing in the Journal of Ethnobiology and Ethnomedicine, Phurpa Wangchuk of James Cook University and co-authors note that the ecological pressure on medicinal plants in Bhutan has increased significantly over recent years, particularly in Lingzhi Gewog, the primary source of plants and other raw materials for medical formulations manufactured for the country’s network of traditional medicine providers:

“[Menjong Sorig Pharmaceuticals (MSP)] manufactures more than 100 different polyingredient medicinal formulations and supplies them to the traditional medicine hospitals and units across the country. The polyingredient medicinal formulations are prepared into different dosage forms as powder, capsules, pills, tablets, ointments and decoctions. The raw materials (mostly medicinal plants) for preparing these formulations are either collected within Bhutan (mostly from Lingzhi region) or imported from India. The medicinal plants, which grow in the higher elevation of alpine mountains (>2000 meters above sea level) including that from Lingzhi region, are known as the High Altitude Medicinal Plants (HAMP) and the others that grow in the temperate and tropical environment are called the Low Altitude Medicinal Plants (LAMP). Due to persistent collections of HAMP from Lingzhi region for more than 48 years, the pressure on medicinal plants has increased significantly over the recent years. Therefore, identifying an alternative medicinal plants collection site for HAMP have been one of the MSP’s top priority.”

Bhutanese g.so-ba-rig-pa medicine is with traditional Tibetan medicine one of the oldest surviving medical traditions and is in wide practice across the world, so this case study is potentially of significance not only for Bhutan but also for the other countries that use these medicinal plants.

The team chose Dagala Gewog to study because it shares several agro-climatic features with Lingzhi Gewog and has never had an ethnobotanical survey (though there were abundant anecdotal claims about medicinal lush plant growth in the region), and because the local people could potentially benefit from a sustainable collection program.

Berberis aristata

Working with a local Byjop guide, the team identified 100 medicinal plant species from Dagala Gewog, 16 of which were abundant in the region and in current use by MSP: Aconitum laciniatum, Berberis aristata, Bistorta macrophylla, Euphorbia wallichii, Gentiana algida, Geranium refractum, Juniperus pseudosabina, Juniperus squamata, Neopicrorhiza scrophulariiflora, Plantago depressa, Potentilla arbuscula, Rheum australe, Rhododendron anthopogon, Rhododendron glaucophyllum, Rhododendron setosum, and Taraxacum officinale.

“These 16 species that are found in abundance have the economic potential since MSP require them in bulk quantities to prepare g.so-ba-rig-pa medicines. Since g.so-ba-rig-pa is also practiced across the globe, these medicinal plants could be in demand by other countries including India, Nepal, Mongolia, Tibet and Switzerland (PADMA company based on Tibetan medicine). However, the first priority would be to focus on meeting the domestic demand of MSP for these medicinal plants. MSP currently engage yak herders for collecting medicinal plants from Lingzhi. As a result of medicinal plants collection program, the Lingzhip (local inhabitants of Lingzhi region) have improved their socio-economic status and contributed significantly to the realization of country’s ‘Gross National Happiness’ (GNH) indices including preservation of traditional medical knowledge, conservation of environment and socio-economic prosperity.”

The team concluded that it was feasible to establish an alternative medicinal-plant collection center in Dagala Gewog:

“Establishing an alternative HAMP collection centre in Dagala Gewog has multi-pronged benefits. The tangible and immediate benefits would include: a) Dagala communities could generate decent income through medicinal plants collection program and elevate their socio-economic status, b) MSP could obtain sustainable supply of HAMP to meet the demand of g.so-ba-rig-pa medicine production, c) training on sustainable collection of HAMP (always provided by MSP as a package of collection program) would educate Dagala Jops on the values, protection and preservation of plants, d) establishing this alternative collection center would ease the pressure on Lingzhi HAMP and could enable MSP to collect the plants on a rotational basis, and e) since Dagala region is known for eco-tourism, having the medicinal plants collection centre and the herb garden would enhance the in-flow of eco-tourists especially the botanists and the herbalists.”

Investigators from Universidad Técnica Particular de Loja, the University of Florida, Universidad Rey Juan Carlos, and Universidad Autónoma de Madrid conducted an ethnobotanical study to catalog medicinal plants sold at traditional markets in southern Ecuador’s Loja Province. The team interviewed 196 vendors at 33 traditional markets in the largest sample of Ecuadorian medicinal-plant market vendors to date.

Writing in the Journal of Ethnobiology and Ethnomedicine, Fani Tinitana and co-authors note the value and limitations of market surveys for ethnobotanical research:

“Current ethnobotanical research at traditional markets across continents, considering Asia, Africa, Oceania, and Latin America, contributes to the understanding of plant diversity through the trade of medicinal plant species and their cultural value. In this way, market surveys can help to understand regional networks of producers, sellers, healers, and consumers by the supply and demand of medicinal plants and their derivative products. The total number of inventoried medicinal plant species at a particular traditional market is important, but they do not necessarily represent all species used in the traditional medicine of a specific human group.”

Matricaria recutita

The study registered 160 medicinal plant species sold to treat a variety of ailments. Two species were particularly important: Matricaria recutita and Gaiadendrum punctatum, used to treat digestive and respiratory systems ailments. Other important species included Ruta graveolens, Melissa officinalis, Equisetum bogotense, Amaranthus hybridus, and Viola tricolor.

In their conclusion, the authors recommend further research on potential therapeutic applications of these medicinal plant species and urge sustainable management of trade as demand is likely to increase:

“For future efforts, it should be important to focus on correlating the values of FL [fidelity level] and FIC [factor of informant consensus] with the incidence of local ailments, as this will be useful to establish public health policies related with the trade of medicinal plant species. This initiative will be effective to support traditional medicine and its therapeutic repertoire. The first step will be to choose the medicinal plant species with widespread and consistent medicinal use in southern Ecuador and to study their therapeutical applications with physicians and scientists, primarily to identify bioactive compounds.

The evidence presented in this study reaffirms the relationship between ancestral wisdom and traditional medicine, particularly in local markets within the Loja province. In fact, it is important to stress how medicinal plant resources are crucial for local people in 13 cities within the Loja province; also, it is important to understand why a high percentage of them practice auto-medication. Reasons for the maintenance of traditional markets include lower cost of plant products, confidence in traditional medicine, and/or sociocultural environment.

This research is the first contribution to understanding from the ethnobotanical point of view the human-plant dynamics of traditional markets within the Loja province, where medicinal plants have a substantial role in the lives of local people. The trade demand of medicinal plants and their derivatives over the next few years could increase, leading to the over-harvesting of wild plant species and could perhaps even endanger natural populations, (e.g., Oreocallis grandiflora). Sustainable management of wild medicinal plants is important for their diversity conservation and in order to avoid their extinction, particularly in the case of highly used species in traditional 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).

Investigators at Bule Hora University and Addis Ababa University conducted an ethnobotanical study of wild edible plants in the Burji woreda of southeastern Ethiopia.

Using guided field walks, semi-structured interviews, and direct field observations, the team documented 46 wild plant species used as food. Two species (Arisaema schimperianum and Amorphophallus gomboczianus) were used to supplement the regular food supply and the remainder were used during food shortages, including seven species consumed during famine (Dovyalis abyssinica, Ehretia cymosa, Euclea divinorum, Ficus sur, Lannea schimperi, Olea europaea, and Rumex abyssinicus).

Noting that wild edible plants are under threat in the district due to anthropogenic pressures and disturbed climatic conditions, the authors make a number of recommendations for collaborative action:

“Ethnobotanical studies are important to promote the conservation and management of the vegetation of a certain area. The loss of indigenous knowledge on wild edible plants may occur if the resources disappear from the landscape. Being a basic source of information about the types of wild edible plants found in the study area and their use, this study would help in maintaining the ecological balance of the area and serve as a wakeup call for other researchers, including ethnobotanists and ecologists, to proceed to more of such studies. It enriches the herbarium and serves as permanent herbarium records and specimens for determination and quick botanical reference in future. In addition to these:

  • Some plants, for example, Ariseama schimperianum could be a very good food source at any time; hence should be given due attention either in maintaining it or improving it through domestication for more intensive usage.
  • Proper consideration should be given in the conservation and keeping of both wild edible plants and associated indigenous knowledge.
  • Expansion of farm lands through clearing forests and woodlands should be stopped by inducing intensive agricultural activities than extensive one through fulfilling different inputs.
  • The local people need awareness raising interventions about the sustainable use of natural resources.”

Investigators at the National University of Sciences and Technology, University of Sargodha, Islamia University of Bahawalpur, and American University of Ras Al Khaimah conducted an ethnobotanical study to compare and document therapeutic flora, their use, and traditional knowledge of residents of the Cholistan Desert and Pothwar (Potohar) Plateau of  Pakistan.

In their introduction, the authors note both the paucity of published ethnobotanical research and the risk of loss of indigenous knowledge from these regions:

“Data regarding ethnobotanical or ethnopharmacologically characteristics of the plants of Cholistan desert and Pothwar is almost non-existent except very few reports. The main objective of present study is to explore the relationship between local culture of folk people and plants in the pursuit of drug development and medical breakthroughs. The herbal treatments in respective regions are favored over the allopathic ones for their low cost and less side effects. The most important objective of this study is the preservation of local plant knowledge. Loss of the indigenous knowledge is a threat to the poor rural economies based on traditional livestock farming as that in the deserts like Cholistan or semi-arid area like Pothwar. It was, therefore, deemed imperative to document the ethnobotany knowledge possessed by the people of respective areas. In addition to this, present study will be a yardstick to probe standardization and systematic exploration of traditional herbs.”

The team documented 67 plant species used in the traditional treatment of human diseases in the Cholistan Desert, and 86 species used in the treatment human diseases in the Pothwar Plateau. Medicinal plants used in both regions (10.5% of the total) included Acacia nilotica, Boerhavia procumbens, Calotropis procera, Citrullus colocynthis, Cyperus rotundus, Peganum harmala, Solanum surattense, Withania somnifera, and Ziziphus nummularia.

The findings from the Cholistan Desert are of particular interest (for example, roughly half of all plant species endemic to the region are used for medicinal purposes):

“Cholistan Desert is uniquely located in wild land with dearth of endemic flora counting only 128 species belonging to 32 families. During the present study people including local elders (Siana), herbal and homoeopathic practitioners and spiritual healers were interviewed. They play an imperative role in primary healthcare of the local inhabitants as the majority of their clients come from poor families who cannot meet the expense of the modern healthcare services. As said by traditional healers, the local people are still dependent on wild plants for prime healthcare owing to the widespread faith in its efficiency. According to the current survey, local people for curing various diseases, commonly use 67 plant species belonging to 29 families. The diseases cured vary from simple stomachache to more complicated such as male and female urino-genital disorders…. 14 plant species are being used for the treatment of gastrointestinal tract disorders. Moreover, it is observed that 16 plant species are consumed as antibacterial and cure for skin diseases. 10 of the plant species are particularly utilized for respiratory tract problems, whereas, for musculoskeletal and joint disorders 10 plant species are used. There are 5 species being consumed for the male sexual disorders, and 10 species for the female sexual disorders. For urinary tract infections 5 plant species have been exploited, and 10 plant species are being consumed as anti-diabetics. In addition to this, traditional healers are using 14 plant species to cure fever, 7 plant species to cure liver diseases, 9 plant species to treat jaundice and renal stones are being cured with 6 plant species. Five plants including Heliotropium strigosum, Withania somnifera, Mukia maderaspatana, Cymbopogon jwarancusa, and Peganum harmala are commonly used for the treatment of CNS disorders, like dementia.”

The authors recommend further documentation and preservation of this rich and unique traditional knowledge, which is in imminent danger of loss, as well as conservation of the medicinal plant species themselves and research on their pharmacological activity.
