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).

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 from the Université de Lomé and Centre de Recherche Biomoléculaire Pietro Annigoni conducted an ethnobotanical survey to document plants used in Togolese traditional medicine to treat asthma in Togo’s southernmost Maritime Region, where the main ethnic groups are the Ewe, Ouatchi, Mina, Fon, and Adja people.

For their study, the team interviewed 121 traditional healers, who use clinical manifestations such as wheezing, coughing, difficulty in speaking, dyspnea, dry cough, sweating, and increased heart rate to diagnose the disease.

Writing in the African Journal of Traditional, Complementary and Alternative Medicines, Gbekley et al. document 98 plant species used in southern Togo to treat asthma, including Carica papaya, Cataranthus roseus, Eucalyptus camaldulensis, Piper guineense, Eucalyptus citriodora, Eucalyptus globules, and Euphorbia hirta. The team conducted a literature review to assess previous relevant ethnobotanical citations related to asthma, toxicity data, and screening reports for immunomodulatory activities.

From the introduction:

“Asthma is a chronic disease characterized by variable airflow limitation and/or airway hyper-reactivity with symptoms causally related to family history, environmental influences, exposure to viruses and allergens as examples. The high economic burden linked with asthma is associated primarily with health care costs, missed work or school days. The treatment of asthma in the modern medicine is based on the use of beta agonists, leukotriene modifiers and inhaled corticosteroids that allowed an acceptable control of the main symptoms. However, this therapy could not suppress all the symptoms although the better understanding of the pathophysiology of the disease. On the other hand, the requirement for daily inhalation with glucocorticoids is often a cause for patient discomfort, limiting the use of glucocorticoids in asthma therapy. In addition, the current therapy is not affordable for the patients in developing countries, who rely on the traditional medicine. Therefore, there is a significant need for new medications for the treatment of asthma that are highly efficacious, with low cost, easily managed and with few adverse effects. In the search for new medications for asthma, plants through the traditional medicine are a credible alternative.”

The authors recommend further laboratory screenings to identify specific bioactive molecules that might be responsible for the reported therapeutic activities of these plant-derived medicines, and to investigate optimal dosages as well as possible side effects.

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).

Researchers at Jiwaji University, University of Freiburg, Forest Research Institute, Karlsruhe Institute of Technology, and Indian Council of Forestry Research and Education conducted a study to document, for the first time, ethnopharmacological preparations of ethnomedicines among the Monpa people in the Zemithang region of Arunachal Pradesh, India. Their study is published in the open-access journal Plants.

From the introduction:

“Before coming to our research objectives, we would like to briefly mention the state of the art of ethnopharmacological research in the Himalayas. There are plenty of research works on the listing of the traditional uses of medicinal plants from the Himalayas. A search with the terms “medicinal plants * Himalayas” yielded 163 peer-reviewed articles listed in ISI Web of Knowledge on 20 February 2017. However, out of those 163 articles, 19 articles were found from the Eastern Himalayas and only two were on the Monpa tribe…. Haridasan et al., in the seminal works produced in 1998 and 1990, comprehensively listed medicinal and edible plants of the Monpa tribe and other tribes of Arunachal Pradesh. Recently, Namsa et al. (2011) listed 50 plant species and recorded their ethnobotanical uses among people of the Monpa tribe at the southern range of their habitation (i.e., Kalaktang circle of West Kameng district of Arunachal Pradesh). These two publications provided general descriptions of the plants, traditional uses of the plants to cure certain diseases, and traditional ways of consumption of these plants or plant parts (e.g., pills, syrups, decoctions, etc.). Nevertheless, no ethnopharmacological studies have yet reported how, and in what proportion, multiple plant parts from different species can be used to prepare specific ethnomedicines for healing of diseases among the Monpa tribes or any other tribes of the Eastern Himalayas as per our literature research as of 20 February 2017. In addition, the traditional knowledges of the people of the Monpa tribe residing at their northern habitation range (i.e., Zemithang circle of Tawang district of Arunachal Pradesh) are still not adequately documented due to the remoteness of the location.”

Aconitum ferox
Aconitum ferox [Source: Wikimedia Commons, Franz Eugen Köhler, Köhler’s Medizinal-Pflanzen]
The team describe 24 ethnomedicines prepared by traditional healers based on 53 plant species, including Aconitum ferox, Bergenia stracheyi, Campanula latifolia, Fragaria nubicola, Gentiana depressa, Hedychium spicatum, Iris clarkei, Leontopodium himalayanam, Meconopsis grandis, Onopordum acanthium, Panax pseudoginseng, Rheum australe, Swertia chirayita, Tanacetum gracile, and Vaccinium nummularia.

In their conclusions, the authors urge further scientific work based on the know-how of Monpa healers, with an eye toward conservation of their traditional ethnopharmacological knowledge:

“We have documented for the first time the vernacular names combined with ethnopharmacological preparations of ethnomedicines among Monpa tribes from the Zemithang region of Arunachal Pradesh, India. Past studies on ethnobotany in the Arunachal Pradesh, Eastern Himalayas, had listed uses of medicinal plants, however, we found that traditional healers use diverse species and plant parts in specific proportions for drug preparations. Our study illustrates the diversity of medicinal drug preparations and traditional knowledge that has passed through generation after generation of Monpa people. The ethnopharmacological documentation presented in this study should motivate researchers to carry out further scientific work on pharmacology, bioprospecting, and the cultivation of medicinal plants for the socioeconomic development in the region. Under ongoing warming of the Himalayas and mass migration of people from the mountain areas to cities, our study also highlights the need to document the traditional knowledge regarding the use of local flora and to develop strategies to conserve them before the traditional knowledges are lost or forgotten.”

PubMed Central: PMC5198176

Researchers from Universidad Politécnica Salesiana and the University of Pavia conducted an ethnobotanical study on the uses of medicinal plants by indigenous people near the Kutukú Scientific Station, which is located on the Kutukú mountain range in the Morona-Santiago province of southeast Ecuador.

About seven indigenous communities live in the study area, all of them members of the Shuar ethnic group:

“The ethnobotanical study performed in this work gave us a real panorama about the natural remedies used by the inhabitants in the territory of the Kutukú Scientific Station of the Morona canton of the province of Morona-Santiago, south of Ecuador. This research was realized with “Shuar” community, which is very different from the “Achuar” community cited in the article by Giovannini, even the geographical location and the altitude are different.”

Acmella ciliata

With guidance from the Shuar, the team identified recorded therapeutic uses of 131 medicinal plants, including Acmella ciliata, Byrsonima arthropoda, Citharexylum poeppigii, Croton lechleri, Ilex guayusa, Siparuna harlingii, Verbena litoralis, and Virola pavonis. Most of the plants are native to the region. Therapeutic uses included aids for wound healing, “mal aire,” diarrhea, nourishment, kidney and bladder affections, fever, and rheumatism.

The authors note the urgency to preserve the cultural patrimony of the Shuar through sustainable research and development:

“In this work we analyzed the ethnobotanical patrimony of Kutukú Scientific Station, located on the Kutukú mountain range in the Morona-Santiago province, Ecuador. By doing that, we intended to safeguard the popular knowledge concerning plants and to produce a database of plant uses and advantages. This data could be used by the citizens themselves and could be the base for future actions in programs of scientific investigations, environmental education, social awareness, and natural resources exploitation, as well as the start point of touristic attraction based on the sustainable development of the territory.”

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.”

Investigators from the Institute of Bioresources and Sustainable Development and Gauhati University conducted surveys at markets throughout the state of Manipur in northeastern India to document wild edible vegetables being used by indigenous communities for nutritive and therapeutic purposes.

About the study area:

“…Manipur, one of the seven states of Northeast India that forms an integral part of the Indo-Burma biodiversity hotspot… is rich in both cultural and biological diversity, having populated by diverse ethnic, linguistic and religious groups including many indigenous tribes. Racially, Manipuri people are unique and have features similar to Southeast Asian. The state has four major ethnic communities – Meitei (Hindu), Naga and Kuki (Tribal communities) and Pangal (Muslim). The Meiteis are the dominant non-tribal community constituting 92% of the valley area along with the Pangal (minority group), and the five hill districts are inhabited by about 34 ethnic tribes representing 30% of the state population. They practice distinct culture and tradition and have different socio-economic features. Agriculture is the single largest occupation in Manipur and the mainstay of the state’s economy. The trade of wild vegetables provides an alternative source of income and is mainly done by women. Forests account for 67% of the total land area of this state. The tribal communities collect a large variety of edible and other useful plants from the forest and surrounding wasteland. They also sell a large variety of such plants in the local market.

The famous “Ima Keithel” (meaning “Mother’s market”) of Manipur which sells vegetables and other household items are exclusively run and controlled by women signifying their role in the society both socio-cultural and economically.”

Through interviews with indigenous plant collectors and sellers, the team documented 68 wild edible vegetables used for nutritive and therapeutic purposes, which they then assessed regarding proper exploitation, conservation, and sustainable management.

Among the most widely used species were Euryale ferox, Chimonobambusa callosa, Ipomoea aquatica, Oenanthe javanica, Alocasia cucullata, Neptunia oleracea, Houttuynia cordata, Hedychium coronarium, Alpinia nigra, Amomum aromaticum, Eryngium foetidum, Passiflora edulis, Ficus benghalensis, and Zanthoxylum budrunga. Several species were found to be consumed mainly by the tribal communities and rarely known to other communities. These included Z. budrunga, P. edulis, Clerodendrum colebrookianum, Spilanthes paniculata, Cissus javanica, Elatostema lineolatum, Plantago erosa, Litsea cubeba, Zehneria scabra, Cyclanthera pedata, Piper pedicellatum, Solanum nigrum, Eurya acuminate, Solanum betaceum, Allium chinense, Heteropanax sp., Dysoxylum gobara, Diplanzium esculantum, Etlingera linguiformis, Derris wallichii, and Phrynium placentarium.

The authors note:

“Many more such unexplored leafy vegetables are believed to exist. There is a need for exploitation of such unexplored resources given the storehouse of traditional knowledge the tribal possessed. It will provide a way for screening newer and alternative source of nutrition.

“The present finding will be useful in the evaluation of nutritional components of high priority species for their integration into the agricultural system based on nutritive values. Further, assessing their cultivable potential and working towards developing agro-techniques can bring more potential species under domestication for conservation through sustainable use. Moreover, it will also help to understand their role in future food and nutritional security of the state. Therefore, documentation and prioritization would ensure that the highest priority species is preserved for use in crop improvement programs and contribute towards achieving the goal of food and nutritional security.”

This study – the first integrated assessment of wild leafy vegetables to be done in the region – provides a methodology to help select and preserve high-priority species for new alternative sources of nutrition.

“According to the integrated assessment, 57 out of 68 (84%) species have good to high value. These high scoring species exhibit the traits of high-quality vegetables, such as taste, appropriate edible parts, multiple edible parts, availability, abundance, easily cultivable, simple to collect and process, and so on. To increase dietary diversity and livelihood sustenance of local people, complimentary studies and further ethnobotanical studies will be conducted. The traditional knowledge and understanding of wild food plants may serve as baseline data for future research and development activities and further biotechnological intervention. A detailed evaluation of nutritional components of the potential species should be conducted for integration into the agricultural system based on their nutritive values and for the conservation of elite germplasm. Further studies should also be done to assess their cultivable potential and work towards developing propagation and agro-techniques to bring more potential wild species under domestication for sustainable utilization of natural resources. Furthermore, proper value chain development for marketing and value-addition of selected species can facilitate enough income to native communities. Documentation and conservation of highest priority species would ensure they are available for use in genetic improvements of crop species as a contribution towards food and nutritional security. Therefore, communities should engage in sustainable management and preservation of traditional knowledge of these multi-valued resources for the well-being local communities.”

Investigators from Makerere University conducted an ethnobotanical study of medicinal plants in 14 villages adjacent to Mabira Central Forest Reserve in Central Uganda, an area about 20 km north of Lake Victoria shoreline immediately to the west of Victoria Nile.

More about the study area:

“The forest reserve occupies gently undulating landscape characterised by numerous flat-topped hills (relics of the ancient African peneplain), and wide shallow valleys…

“Commercial use of the forest began when some parts were harvested in the early 1900’s and until 1988, intensive coffee/banana agricultural encroachment badly damaged parts of the forest. About 21% and 26% of the reserve have been designated as strict nature reserve and buffer zone respectively and the forest in these areas is recovering following extensive plantings of native tree species.

“The human population living in the forest enclaves was approximately 825,000 with a density of 200–230 people per Km-2. The local people are mainly of the Bantu ethnic group of the following tribes; Baganda, Banyarwanda, Basoga, Bagisu, Bakiga, Banyankole, Bagwere and Batoro.

“The reserve has tea and sugarcane plantations around. Some local people reside in settlements for labourers on the tea and sugarcane estates. The extent of growing cash crops other than tea and sugar cane is limited by scarcity of land. However locals are engaged in cultivation of food crops mainly for subsistence consumption like maize, beans, bananas, ground nuts, sweet potatoes and vegetables. Livestock rearing is limited to a few households.”

The team documented 190 plant species used in the treatment of various health conditions. The ten most important medicinal plant species were Vernonia amygdalina, Mormodica feotida, Warbugia ugandensis, Prunus africana, Piptadeniastrum africana, Erythrina abyssinica, Albizia corriaria, Spathodea campanulata, Mondia whitei, and Alstonia boonei.

Vernonia amygdalina
Vernonia amygdalina [Photo: By Kwameghana (Own work) [CC BY-SA 4.0 (http://creativecommons.org/licenses/by-sa/4.0)], via Wikimedia Commons]
Vernonia amygdalina was found to be an especially important species, with a fidelity level of 100% and ranking highest in the treatment of malaria:

“Its leaf extract has been confirmed for having good anti-malarial effects and through in vitro studies. Vernonia amygdalina contains steroid glycosides, sesquiterpene and lactones which are active against Plasmodium falciparum. This species has also been found to be clinically effective for the treatment of malaria patients. In human trials, extracts of Vernonia amygdalina reduced parastaemia by 32%. Although Vernonia amygdalina is effective for malaria treatment, it can induce labour in pregnant women thus causing miscarriages and therefore should be avoided by them. Species with high fidelity level such as Vernonia amygdalina for malaria and Erythrina abyssinica for vomiting indicates that these species two were considered of great cultural significance. Erythrina abyssinica too has a wide range of use varying from treatment of malaria, syphilis, tuberculosis to amoebiasis in Uganda. In Kenya E. abyssinica is used to treat mumps, respiratory tract infections in Mexico and febrile illness in Ethiopia. Its usage for different ailments is possibly due to a wide range of bioactive compounds.”

In their conclusion, the authors found that “the diversity of medicinal plant species used and the associated indigenous knowledge are of great value to the local community and their conservation and preservation is paramount.”

“The study shows that [Mabira Central Forest Reserve] habours a wide diversity of plant species used as remedies for several ailments. Such plants are very useful especially to people who cannot afford modern medical care and in cases where access to modern heath facilities is not easy. Knowledge and use of herbal medicine for treatment of various ailments among the local people is still part of their life and culture and this calls for preservation of the integrity of the forest and indigenous knowledge of herbal medicine use. The documented plants have potential of being used in drug development.”

Ethnobotany of the Balti community, Tormik valley, Karakorum range, Baltistan, Pakistan

Abbas Z, Khan SM, Abbasi AM, et al
J Ethnobiol Ethnomed. 2016 Sep 9;12(1):38
PubMed Central: PMC5018187

Investigators at Hazara University, Quaid-i-Azam University, COMSATS Institute of Information Technology, South China University of Technology, University of Gastronomic Sciences, and University of Swat conducted a study “to document the ethnobotanical knowledge of the local peoples in the Tormik Valley, especially in the medical and food domains.”

The Tormik Valley is home to the Balti ethnic group:

“Overall in the Baltistan region (province), Mongol, Mon, Hor, Brokpa and Kashmiris are the prominent ethnic groups with the local languages being Balti and Shina (Broq-skat); however, the studied valley hosts a single ethnic group: the Balti. This ethnic group is comprised of thirty-one lineage groups known as qoum and speaks Balti as their local language. The population of the valley is approximately 5,000 inhabitants comprising 706 households. The people of this region migrated to the study area from other parts of Baltistan, as well as other regions, before the birth of the founder of Buddhism, Guatama Budha (563 BC).”

The team gathered ethnobotanical data using semi-structured interviews and group conversation with 69 participants during field trips in 14 different villages, and documented 63 plant species with detailed folk uses, including 43% used to treat various diseases, 21% consumed as wild fruits and vegetables, and 53% with multipurpose applications.

This is the first in-depth ethnomedicinal survey of the Tormik valley:

“In mountainous ecosystems such as the Karakorum range, often inadequate nutrition remains a major problem resulting in various diseases. The local inhabitants in these areas have developed traditional methods of curing such common health problems, which in turn can provide important data for devising public health policies. The Karakorum mountain range, situated at the junction of western and central Asiatic regions of Tethyan flora, is one of the most diverse habitats in the world. The Baltistan province of Pakistan is home to more than a dozen geographically isolated and botanically unexplored valleys in the Karakorum Range. Although a number of previous ethnobotanical investigations have been conducted in surrounding areas, many of these studies did not use quantitative methods. Moreover, Tormik Valley repeatedly went unnoticed, perhaps due to its high altitude, harsh and hostile climate, inaccessibility and prevailing poverty. A large proportion of its inhabitants depend on herbal remedies. They are known as the trustees of cultural knowledge whether related to plants, animals, fungi, lichens, or stones.”

Twenty-six medicinal plant species were used to treat human ailments, including gastrointestinal diseases, dermatitis, jaundice, hepatitis, cancer, pneumonia, tonic, asthma, urinary disorders, joint pain, and eye pain. Thymus linearis, Hippophae rhamnoides, and Convolvulus arvensis were the most used medicinal plant species.

The authors note several implications for public health and environmental policies:

“…[I]t is clear that stomach related health problems (ulcers, constipation, GIT infections, jaundice), and skin diseases (dermatitis) are the most prevalent health problems in the area. Stomach disorders are likely due to malnutrition and unhygienic food utilization. Skin problems can be attributed to the high altitude of the study area, where radiation from the sun tends to be more intense and potentially mutagenic. People traditionally treat such diseases with food-medicines, which in many cases are quite effective. Hence, the present findings provide very important insights for public-health officials, to formulate health policies taking into account the common health issues and Traditional Medicine practiced by the local people as part of their primary healthcare.
“…The present study revealed that the valleys in the Karakorum Mountains in Northern Pakistan support a notable Traditional Knowledge on the local plants. Wild food plants have represented the milestone of the traditional food systems and could still represent a pillar of the local food sovereignty, while medicinal plants play a vital role, which need to be reconsidered and carefully re-evaluated by ethnopharmacologists and public health actors. The collected data may be also of interest to initiatives aimed at fostering sustainable rural development in an area that faces serious economic problems, widespread illiteracy, and isolation. The findings of this paper advocate the need for comprehensive trans-disciplinary researches aimed to ensure the dynamic conservation of invaluable local knowledge systems, as well as plant diversity in Pakistani mountain regions.”

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.”
