Ethnobotanical survey of medicinal plants at periodic markets of Honghe Prefecture in Yunnan Province, SW China

In China, traditional markets are considered as important places for trading of medicinal plants harvested by rural villagers, which also play a social role of exchanging traditional use of herbal medicine among different cultural and social groups at local level. Market survey is often engaged in ethnobotanical studies for documenting locally used herbal plants and associated traditional knowledge. Information collected from market survey is also useful for plant conservation in the habitat areas. However, information on the market traded medicinal plants is not well documented from traditional markets in Honghe Prefecture, Yunnan. The study aimed to look into medicinal plants that are used by local people for curing various ailments. Ethnobotanical market survey methods, interviews, Participatory Action Research (PAR) and field visits were planned to elicit information on the uses of various medicinal plants. It was found that 216 plant species are commonly used by local people for curing various diseases, of which 173 species (80.1%) are wild plants and 43 species (19.9%) are home garden plants. A total of 278 records of medical uses in 60 herbal recipes for the treatment of 16 types of common diseases were recorded. In most of the recipes recorded, digestion diseases (30.6%) were used. The rest are rheumatological diseases (13.0%), respiratory system diseases (10.4%), infectious diseases (7.9%) and surgery uses (7.9%). The knowledge about the number of medicinal plants available in that area and used by interviewees was positively correlated with the threats on medicinal plants in the wild habitats of the study area, indicating that the diversity of medicinal plants and the associated traditional knowledge trends to disappear in the area.

Plant genetic resources and traditional knowledge on medicinal use of wild shrub and herbaceous plant species in the Etna Regional Park (Eastern Sicily,Italy)

Ethnopharmacological relevance

This paper illustrates the results of a study carried out in the Etna Regional Park (Eastern Sicily, Italy) concerning the traditional knowledge on medicinal use of wild plant species. It contains the results of a quantitative analysis carried out for the first time. A total of 71 wild species are used for medicinal purposes. Two species, Astracantha sicula (Biv.) Greuter and Trifolium phleoides Willd., are little known as medicinal in the Mediterranean area. The main aim of the study was to understand to what extent current knowledge on the medicinal use of plants is still an element of the culture within the elderly population of the Etna Regional Park. A further aim was to identify species not previously reported as medicinal in the Mediterranean area with a potential agricultural interest.

Methodology

The information was obtained using a semi-structured interview format performed on a sample of 196 people over the age of 60 who were considered experts in rural traditions. The plant uses were compared with other medical-ethnobotanical studies carried out in other areas of Sicily, Italy and various other Mediterranean countries. A number of quantitative indices were also used in order to verify the incidence of the species cited in the study within the culture and traditional medicine.

Results

Local communities currently use a total number of 71 wild species (34 families) as remedies for medicinal purposes. Most of the species were used as treatments against metabolic disorders and for general health. The leaves and the aerial parts of plants are the most-used parts of the plant and the most common preparation methods are decoction and direct application of plant parts. Astracantha sicula and Trifolium phleoides have never been documented as a species with medicinal properties in the Mediterranean literature.

Conclusions

Only very few medicinal uses are widely known by all the informants and, on many occasions, a specific medicinal use is cited by only very few people. The quantitative analysis shows that the level of traditional knowledge on medicinal use of plants in the study area is poor, highlighting a considerably advanced state of cultural erosion.     

Nepalese traditional medicine and symptoms related to Parkinson׳s disease and other disorders: Patterns of the usage of plant resources along the Himalayan altitudinal range

Ethnopharmacological relevance

Nepal is a hotspot for cultural and biological diversities. The tremendous diversity of ecosystems and climates and the blend of medicinal practices inherited from Ayurvedic and Traditional Tibetan Medicine are well suited to a study aimed at discovering information about medicinal plants to treat Parkinson’s disease (PD). In addition, this study across Nepal’s altitudinal range is relevant to understanding how cultural and ecological environments influence local traditional medicines. The aim of the study is to document the uses of medicinal plants in three different eco-geographical areas of Nepal (Chitwan–Panchase–Mustang) to treat symptoms related to PD. A second goal is to analyze the impact of culture and environment on the evolution of traditional medicine.

Materials and methods

The study was conducted in five communities located in three different eco-geographical environments and at altitudes ranging from 300 m to 3700 m. We interviewed a total of 56 participants (local people, folk, Ayurvedic and Amchi healers) across the three research areas. We conducted open-ended interviews to document the uses of medicinal plants to treat PD-related symptoms. Information provided by the interviewees suggested that the medicinal plants are also used to treat symptoms related to other disorders. We determined the informant consensus factor as well as the importance of specific plant species to (i) identify plants that are the best candidates to be analyzed experimentally for their potential to treat PD and (ii) perform a cross-cultural comparison of the three areas of study.

Results

This study reports the local uses of 35 different plant species along the Chitwan–Panchase–Mustang altitudinal range. We identify a total of eight plant species that were used in all three research areas, and more specifically one species used to treat PD-like symptoms. We identify a potential dual protective activity of medicinal plants used to treat PD-related symptoms as recent literature suggests that these plants also have anti-cancer properties. In addition, we document that the presence of Ayurvedic healers could influence local practices and that local practices could influence local Ayurvedic practices.

Conclusions

This study documents the uses of medicinal plants to treat symptoms related to PD and other disorders across the Chitwan–Panchase–Mustang altitudinal range. PD is a neurodegenerative disease affecting a growing number of people worldwide. No cures are available to slow the death of the neurons, and there is a critical need to work towards innovative therapeutic strategies. We identify medicinal plants based on traditional practices to help develop a cure for PD. The three areas of study were chosen for their ecological and cultural diversities, and two of these are included in conservation programs (Panchase Protected Forest and Annapurna Conservation Area). The documentation of community–natural resource relationships is another step in the preservation of traditional practices and local biodiversity and a reflection of communities’ rights in the design of conservation programs.     

Ethnopharmacological survey of medicinal herbs in Jordan, the Ajloun Heights region

The study of local knowledge about natural resources is becoming increasingly important in defining strategies and actions for conservation of medicinal plants. This study therefore sought to collect information from local population concerning the use of Ajloun Heights region medicinal plants; identify the most important species used; determine the relative importance of the species surveyed and calculate the informant consensus factor (ICF) in relation to medicinal plant use. Data collection relied predominantly on qualitative tools to record the interviewee's personal information and topics related to the medicinal use of specific plants. Our results revealed that 46 plant species grown in the study region are still in use in traditional medicine for the treatment of various diseases. Most of the locals interviewed dealt with well-known safe medicinal plants such as Achillea falcata, Matricaria aurea, Majorana syriaca, Allium sativum and Allium cepa. The use of moderately unsafe or toxic plants was noted to be practiced by practitioners and herbalists rather than the locals. These plants include Ecballium elaterium, Euphorbia hierosolymitana, Mandragora autumnalis and Citrullus colocynthis. Kidney problems scored the highest ICF while Crocus hyemalis was the plant of highest use value. Searching the literature evidenced some concordance with the solicited plant uses mentioned by the informants.     

Medico-religious plants used by the Hajong community of Assam,India

Ethnopharmacological relevance

The Hajong people use many medicinal plants in their different rituals. The information generated from the present study regarding the medico-religious plants used by the Hajong tribes need a thorough phytochemical investigation. This could help in creating awareness regarding the need for conservation of such plants and also in the promotion of ethno-medico-botany knowledge within the region besides contributing to the preservation and enrich- ment of the gene bank of such economically important species before they are lost forever. Medico-religious plants so found out in this study should be screened for their efficacy by which new drugs or products could be brought out. There is also need to document this information and compare with that of other tribes in the state and region.

Materials and Methods

The diseases found during the research work among the Hajong community were grouped in 11 categories. The category of diseases includes plants used for both human and animal diseases. The informants having good knowledge on medico-religious plants were chosen for the interview. Kabiraj or Vaidyas were also included among the informants though they were not available in all villages. The informants were asked about the ritual and religious importance and the medicinal properties of the plants used in different cultural practices.

Results

Some 36 plant species including herbs, shrubs and trees are used for curing 51 different diseases with 63 formulations which are recorded during the study. Most of the medicinal plants were collected from their own homestead and rest from the forest. Hajongs make sustainable use of available natural resources that include both medicinal and religious plants. They lead a much disciplined life. They are very much religious and knowledgeable. The survey revealed that not only the Kabiraj but also the elder community member have good knowledge of the medicinal value of some plant usually those species used to treat common diseases like cough, cold, fever, viral fever, headache, stomachache, joint pain, diarrhea, dysentery, minor wounds and cuts etc. Thus 36 plants are found to be used by Hajong in different medico-religious practices. These are regarded as holy plants. These plants are strictly protected by the community. Traditional conservation and management on cultural grounds, therefore, represents a historic contribution to the present day rich biodiversity in the region.

Conclusion

The whole life system and socio-economic as well as religious and cultural activities of Hajongs were totally dependent upon forests. It reflected their high possession of knowledge on medico religious plants which allowed them to apply their indigenous knowledge regarding various aspects of exploitation of such resources. Different types of important species have been disappeared from the study area, which ultimately creates social, economical and religious problem in Hajong community. The information generated from the present study regarding the medico-religious plants used by the Hajong tribes need a thorough phytochemical investigation. This could help in creating awareness regarding the need for conservation of such plants and also in the promotion of ethno-medico-botany knowledge within the region besides contributing to the preservation and enrichment of the gene bank of such economically important species before they are lost forever. Traditional culture in different Hajong populated areas is very fast declining with lot of traditional knowledge under the influence of dominant culture. Cultural diversity conservation is needed urgently.     

Ethnobotanical study of medicinal plants from the Humla district of western Nepal

Aim of the study

The present paper documents the uses of plants in traditional herbal medicine for treatment of human and veterinary ailments in four village development committees in the Humla district of western Nepal. It also determines the homogeneity of informant's knowledge on medicinal plants suitable for different ailment categories and the most preferred plant species used to treat each ailment category in the study areas.

Materials and methods

The ethnobotanical information was collected through semi-structured interviews and key informant discussion. The data were analyzed through informant consensus factor (ICF), fidelity level (FL) and use value (UV).

Results

We documented 161 plant species belonging to 61 families and 106 genera used for treating 73 human and 7 veterinary ailments. We also documented culinary uses and additional uses for 67 and 33 species of medicinal plant species respectively. Most medicines were prepared in the form of powder and used orally. Roots were most frequently used plant parts. The uses of 93 medicinal plants were not mentioned in any previous studies. Gastro-intestinal ailments have the highest ICF (0.40) whereas opthalmological uses have the lowest (zero) ICF. Mentha spicata and Rumex hastatus has the highest FL (100% each) both being used for gastro-intestinal ailments and Delphinium himalayai has the lowest (47.4%) for veterinary uses.

Conclusions

ICF values indicated that there was high agreement in the use of plants in gastro-intestinal ailment category among the users. FL or UV values indicated the most preferred plant species used in study areas. These preferred plant species could be prioritized for conservation and subjected to further studies related to chemical screening for their authenticity. Most of the medicinal plants of the region are collected in the wild and are often harvested for trade. Sustainable harvesting methods and domestication of the highly traded species is thus needed in the study areas.     

An ethnobotanical study of medicinal plants used by the Zay people in Ethiopia

An ethnobotanical survey was carried out to collect information on the use of medicinal plants by the Zay people who live on islands as well as shore areas of Lake Ziway in the Ethiopian Rift Valley. A total of 33 medicinal plants were reported as being used locally for the treatment and/or control of human and livestock ailments. Results of the survey showed that leaf materials form the major component of plant parts harvested. The majority of the remedies are prepared in the form of juice from freshly collected plant parts. Most of the remedies are prepared from a single species, and are mainly taken orally. Most of the medicinal plants are collected from the wild. Of the total claimed medicinal plants, 10 were reported scarce locally. Environmental degradation and intense deforestation have been reported as the main causes for the depletion of medicinal plants in the area. As the Zay people are still partly dependent on medicinal plants, loss of these plants will, to a certain extent, hamper the existing health care system in the area. Measures for conservation of medicinal plants of the Zay people are urgently needed.     

Use of medicinal plants in the South-Eastern area of the Partenio Regional Park (Campania,Southern Italy)

Ethnopharmacological relevance

This study documents the pharmaceutical importance of plant resources in the South-Eastern area of the Partenio Regional Park (PRP), inland Campania, Avellino province. This is reflected in the great diversity of plants used for medicinal purposes as well as in their wide range of medicinal applications.

Materials and methods

In order to collect information on medicinal plants used in the investigated area and to maximize the collection of local knowledge, informants were randomly contacted in the streets, squares and fields. Data were collected through both open and semi-structured interviews with native people between April 2012 and April 2013.

Results

The study recorded 87 plant species belonging to 76 genera and 35 families used as medicine for treating various diseases, both human and veterinary. Herbs represent the majority (56 species), followed by trees (18) and shrubs (13). Among the recorded plants, leaves were the most frequently used and topic use is the most common remedy. Cough is the most treated human disease followed by wounds healing.

Conclusion

The investigated area is endowed with a strong tradition of herbal medicine usage for primary healthcare (PHC). The preservation of this knowledge is due to the continued use of plants for PHC by the local community. This is due to the fact that in the study area still exists an oral tradition that allows the persistence of such information. Recovering ancient knowledge is very important for preserving ethno-biodiversity and to discover new entities for a further evaluation of their biological activity.     

Indigenous knowledge of medicinal plants used by the Reang tribe of Tripura state of India

Ethnopharmacological relevance

Traditional remedies used for the treatment of various ailments are considered to be very important in the primary health care of Reang people living in Tripura state of Northeast India. Novel information gathered from the present investigation is important in preserving folk indigenous knowledge of Reang tribe.

Methods

Systematic and exhaustive field surveys were conducted during 2003 to 2004 in Reang inhabited areas of Tripura state of Northeast India covering all the seasons, to gather information on medicinal herbs used by them in the treatment of various ailments. Information was collected from 55 traditional herbalists of different age through structured questionnaires and personal observations made during the field visit. The data obtained was analyzed through informant consensus factor (F_IC) to determine the homogeneity of informant's knowledge on medicinal plants also the fidelity level (FL) to authenticate the uniqueness of a species to treat a particular ailment.

Results

In the present study a total of 125 medicinal plants species belonging to 116 genera and 59 families were presented, used for treating 42 different ailments. The major plant parts used are leaves and most of the remedies are suggested to take orally. The greatest parts of plants used for curing various ailments were found locally. The consensus analysis revealed that the fever and gastro-intestinal diseases have the highest informant consensus factor F_IC of 0.79 followed by the dermatological problems (F_IC 0.78). It is equal (F_IC 0.77) for both general health problems and inflammation and pain while urinogenital problems showed relatively low levels of consensus (F_IC 0.63). The level of informants' consent was high for most ailment categories indicating greater homogeneity among informants. In the present study we analyzed the disease categories to highlight some of the important plant species in terms of Fidelity level. Greater parts of the plant species achieve highest fidelity level, while only 4% acquire lower FL. The species with high citation and informant concurrence value are reasonably significant. Cyathea, a rare tree fern used for major cuts or wounds for immediate blood coagulation. Extensive local application may threaten the species if not judiciously managed.

Conclusion

The traditional pharmacopoeia of the Reang ethnic group incorporates a myriad of diverse flora available locally. Traditional knowledge of the remedies is passed down through oral traditions without any written document. This traditional knowledge is however, currently threatened mainly due to acculturation and deforestation. Therefore, documenting medicinal plants and associated indigenous knowledge can be used as a basis for developing management plans for conservation and sustainable use of medicinal plants of the study area. In addition, findings of this study can be used as an ethnopharmacological basis for selecting plants for future phytochemical and pharmaceutical studies.     

Use patterns and knowledge of medicinal species among two rural communities in Brazil's semi-arid northeastern region

The present work seeks to quantify the knowledge of two rural communities in the semi-arid region of the state of Pernambuco (northeastern Brazil) concerning two species of native medicinal plants: "aroeira do sert?o", Myracrodruon urundeuva (Engl.) Fr. All. (Anacardiaceae) and "angico", Anadenanthera colubrina (Vell.) Brenan (Mimosaceae). Semi-structured interviews were carried out, combined with a checklist/inventory method, which yielded different indexes for quantifying knowledge and use of these species. In addition, the reliability of local knowledge was tested using analytical techniques to determine actual tannin concentrations. Although both communities possess knowledge concerning these two species, one of them stood out in terms of the diversity of information presented (P < 0.05), a difference that may be related to its lower degree of modernization. In general, older people had a greater variety of information about these plants, although both men and women demonstrated similar knowledge. Of the 101 people interviewed in Riach?o, 85% stated that they knew of uses for both species studied; in Ameixas, of the 55 interviewees, 63% responded that they knew of uses for Myracrodruon urundeuva, and 45% knew of uses for Anadenanthera colubrina. A total of 97 different uses were reported by all informants for the two species studied. Of these, 62 were mentioned in only a single community, confirming our hypothesis of differences in knowledge between them. Informants from both communities knew of a great variety of uses for these plants as well as a number of different collection techniques. We expected that knowledge about the two species would differ in relation to both gender and age, but this was only true for one of the communities. Greater concentrations of tannins were expected to be found consistently in the tree bark, but experimental data demonstrated that tannin concentrations can vary among plant parts during the year.     

An ethnobotanical study of medicinal plants and traditional therapies on Batan Island,the Philippines

Ethnopharmacological relevance

We studied the local knowledge and uses of medicinal plants among the Ivatan people of Batan Island by documenting their traditional practices.

Aim of the study

To identify the types of medicinal plants used in self-care by the indigenous people of Batan Island, the Philippines and to investigate the extent to which the plants are used. Conservation of medicinal plants and natural resources is becoming increasingly important; thus, this research aims to collect information from local people concerning the use of medicinal plants on Batan Island.

Materials and methods

A total of 116 informants were interviewed, allowing for calculated informant consensus factors (ICF), use value (UV), and fidelity levels (FL) for each medicinal plant species used to cure various ailments. This helped to establish a consensus on which species are effective for particular ailments, as well as the species’ relative importance, and enabled us to understand the extent of the potential utilization of each species.

Results

We describe the therapeutic effects of 112 plant species used medicinally against 13 categories of ailments. The highest ICF value (1.00) was cited for diseases of the ear and respiratory system and for use during pregnancy, childbirth and the postnatal period. The maximum FL of 100% was found for Carica papaya, Stachytarpheta jamaicensis, Musa sapientum, and Pedilanthus tithymaloides, used for the treatment of constipation, cuts and wounds, diarrhea, and dislocations and fractures, respectively. The highest UV was for Hibiscus rosa-sinensis (0.67). All plants with high UV were used for exogenous diseases, certain infectious and parasitic diseases, injuries, poisonings and other consequences of external factors, and diseases of the skin and subcutaneous tissues. In addition to its use for endogenous disease and lifestyle-related diseases and illnesses, Moringa oleifera is also used for diseases of the circulatory system, with a UV of 0.57 and Cocos nucifera is used for diseases of the genitourinary system, with a UV of 0.56.

Conclusions

This study demonstrates that many plant species play an important role in local healing practices and that knowledge of traditional medicine is still utilized and plays a significant role on Batan Island. The documentation of this rich traditional ethno-medicinal knowledge has furnished us with novel information that not only will provide recognition of this undocumented knowledge but also could provide new avenues for pharmacological investigations to improve healthcare for a range of ailments.     

Ethnobotanical survey of usage of fresh medicinal plants in Singapore

Ethnopharmacological relevance

The use of medicinal plants in human health has been documented since ancient times and they provide a useful source of new therapeutics. In Singapore, despite the accessibility to modern healthcare, there still exist pockets of the population who choose to use locally grown fresh medicinal plants for health promotion and even therapeutic purposes. However to date, there is no published report of first-hand account of their usage in Singapore. As land is scarce and rapidly used for re-development, such important knowledge may be lost if not properly documented in time. This work safeguards the local folk knowledge, and provides information on common and scarcely reported fresh medicinal plants. The objective of this study is to gather information regarding the usage of fresh medicinal plants in Singapore through face-to-face interviews.

Materials and Methods

Information on demographic data and plant-use methods were collated via face-to-face interviews of 200 fresh medicinal plant users who have used fresh medicinal plants in the last five years. The survey protocol was approved by the National University of Singapore Institutional Review Board and informed consent was obtained from every participant.

Results

A total of 414 plants represented by 104 plant species from 44 families were reportedly used by the 200 participants. The five most commonly used plants were Clinacanthus nutans (34 users), Strobilanthes crispus (31 users), Pereskia bleo (25 users), Aloe vera (18 users) and Zingiber officinale (16 users). Leaves were the most commonly used plant part while preparing a decoction was the most common method of preparation. The majority of interviewees used plants for general health purposes and to treat diseases related to the respiratory system and cancer.

Conclusions

Our survey has successfully documented the rich wealth of traditional usage and knowledge on 414 fresh medicinal plants grown in Singapore through face-to-face interviews with 200 users. This study will serve as a useful resource for identifying promising plants for future drug discovery efforts. Scientific evaluations of these medicinal plants are warranted and should be carried out.

The use of medicinal plants is still widespread especially in the villages and is usually the first treatment utilised. Fifty nine local plant species used for treating various illnesses were collected, identified and deposited in the Fourah Bay College Herbarium. Their medicinal uses and methods of preparing the drug are described.     

Ethnopharmacological notes about ancient uses of medicinal plants in Trás-os-Montes (northern of Portugal)

Aim of the study

In order to preserve the ancestral knowledge, an ethnopharmacological study has been carried out in two councils belonging to Trás-os-Montes region a small area located in the northern of Portugal. In that area, medicinal plants, most of the species wild, are still in use among farmers, shepherds and other people who live far from villages and built-up areas.

Materials and methods

Among the 46 people that were interviewed (mean age of 66 years old), 88 species belonging to 42 families of vascular plants were identified for treatment of various human ailments. An ethnopharmacological report is made consisting of species names, vernacular names, popular uses of the plants and their pharmacological properties.

Results and conclusion

The most dominant family is Lamiaceae (18%) and the most frequently part of the plant used for the treatment of diseases are leaves (37.9%). The largest number of taxa is used to treat gastrointestinal disorders (73.9%).     

Traditional use of the native medicinal plant resource of Mt. Rtanj (Eastern Serbia): Ethnobotanical evaluation and comparison

Ethnopharmacological relevance

This study reports on the uses of medicinal plants and ethnobotanical significance of Mt. Rtanj, Eastern Serbia. The aim of the study was collecting information on plant utilization and creating the list of medicinal plants collected by local community in the region of Rtanj Mt. in Serbia.

Methodology

A group of generally elderly people from the region were interviewed, asked to identify a certain number of plant taxa used against various human ailments. A quantitative ethnobotanical comparison has been performed in relation to other studies concerning the central Balkan Peninsula.

Results

There is an inventory of 45 plant species recorded. At the family level, the most common in traditional usage were species of Labiatae (22%), Rosaceae (20%) and Compositae (13%). The results of the survey suggested that Hypericum perforatum was the most popular medicinal plant. Among the 7 different recorded types of preparation, the aerial parts of plants were the most popular (47.3%). The most frequently reported medicinal uses of herbal drugs include remedies for immune system (22.97%), respiratory system (15.77%) and digestive system disorders (15.32%). However, a comparatively small number of available plant species was used for medicinal purposes while the level of ethnobotanical diversity was lower when compared to adjacent regions.

Conclusions

Ethnobotanical knowledge in this area is decreasing due to high emigration rates during the last period. The historically developed ethnobotanical heritage should be preserved and promoted on the larger level, getting the special position in the future management plans for this area.     

Traditional antimalarial phytotherapy remedies used by the Kwale community of the Kenyan Coast

In Kenya, most people especially in rural areas use traditional medicine and medicinal plants to treat many diseases including malaria. Malaria is of national concern in Kenya, in view of development of resistant strains of Plasmodium falciparum to drugs especially chloroquine, which had been effective and affordable. There is need for alternative and affordable therapy. Many antimalarial drugs have been derived from medicinal plants and this is evident from the reported antiplasmodial activity. The aim of the study was to document medicinal plants traditionally used to treat malaria by the Digo community of Kwale district. Traditional health practitioners were interviewed with standardized questionnaires in order to obtain information on medicinal plants traditionally used for management of malaria. Twenty-five species in 21 genera and 16 families were encountered during the study. Celestraceae, Leguminosae and Rubiaceae families represented the species most commonly cited. Three plant species, namely; Maytenus putterlickioides, Warburgia stuhlmannii and Pentas bussei are documented for the first time for the treatment of malaria.     

Medicinal plant use in the practice of midwifery in rural Honduras

Midwives in rural communities across the globe play an important role as primary health care providers, but few studies have documented the medicinal plants employed in this age-old practice. Semi-structured interviews were conducted with 23 midwives in seven rural communities near La Ceiba, Honduras, regarding the plants they employ during the birthing process as well as their associated beliefs. Seventy-nine different plant species used to treat 15 conditions occurring during the pregnancy, birth and postpartum stages were recorded. Most plants and uses were reported by only one or two midwives, reflecting the fact that most midwives in this region had immigrated from different parts of the country. Almost all the midwives used or knew of plant remedies for treatment of miscarriages, postpartum abdominal pain and hemorrhages, retained placenta, and for speeding up contractions during labor. The most frequently cited plants as well as those for which there was greatest consensus tended to be widespread cultivated or weedy species. Although use of medicinal plants by midwives has decreased as a result of retraining programs by government health centers, midwives' knowledge of medicinal plants may provide an important resource for improving maternal-infant health in Honduras and elsewhere. Suggestions for future ethnobotanical and ethnopharmacological studies on this topic are provided.
