    climate change - ethnobotany - medicinal plants - sustainability - traditional knowledge - traditional medicine

    The recent publication of a World ScientistsÊ Warning to Humanity highlighted the fact that climate change, absent strenuous mitigation or adaptation efforts, will have profound negative effects for humanity and other species, affecting numerous aspects of life. In this paper, we call attention to one of these aspects, the effects of climate change on medicinal plants. These plants provide many benefits for human health, particularly in communities where Western medicine is unavailable. As for other species, their populations may be threatened by changing temperature and precipitation regimes, disruption of commensal relationships, and increases in pests and pathogens, combined with anthropogenic habitat fragmentation that impedes migration. Additionally, medicinal species are often harvested unsustainably, and this combination of pressures may push many populations to extinction. A second issue is that some species may respond to increased environmental stresses not only with declines in biomass production but with changes in chemical content, potentially affecting quality or even safety of medicinal products. We therefore recommend actions including conservation and local cultivation of valued plants, sustainability training for harvesters and certification of commercial material, preservation of traditional knowledge, and programs to monitor raw material quality in addition to, of course, efforts to mitigate climate change.

    herbals baths - medicinal plants - Suriname - Maroons - Saramaccan - Aucan - traditional knowledge - traditional medicine
    Background Herbal baths play an important role in the traditional health care of Maroons living in the interior of Suriname. However, little is known on the differences in plant ingredients used among and within the Maroon groups. We compared plant use in herbal baths documented for Saramaccan and Aucan Maroons, to see whether similarity in species was related to bath type, ethnic group, or geographical location. We hypothesized that because of their dissimilar cultural background, they used different species for the same type of bath. We assumed, however, that plants used in genital baths were more similar, as certain plant ingredients (e.g., essential oils), are preferred in these baths. Methods We compiled a database from published and unpublished sources on herbal bath ingredients and constructed a presence/absence matrix per bath type and study site. To assess similarity in plant use among and within Saramaccan and Aucan communities, we performed three Detrended Correspondence Analyses on species level and the Jaccard Similarity Index to quantify similarity in bath ingredients. Results We recorded 349 plants used in six commonly used bath types: baby strength, adult strength, skin diseases, respiratory ailments, genital steam baths, and spiritual issues. Our results showed a large variation in plant ingredients among the Saramaccan and Aucans and little similarity between Saramaccans and Aucans, even for the same type of baths. Plant ingredients for baby baths and genital baths shared more species than the others. Even within the Saramaccan community, plant ingredients were stronger associated with location than with bath type. Conclusions Plant use in bathing was strongly influenced by study site and then by ethnicity, but less by bath type. As Maroons escaped from different plantations and developed their ethnomedicinal practices in isolation, there has been little exchange in ethnobotanical knowledge after the seventeenth century between ethnic groups. Care should be taken in extrapolating plant use data collected from one location to a whole ethnic community. Maroon plant use deserves more scientific attention, especially now as there are indications that traditional knowledge is disappearing.

    Summary

    Plants still play an overriding role in African traditional medicine, as large sectors of the continent’s population prefer or considerably rely on herbal treatments as their primary source of health care. Traditional medicine, which is defined as the sum of knowledge, skills, and practices used to prevent and treat diseases, often involves consultation with spiritual healers and diviners, who in turn consult supernatural entities to diagnose their patients. At the same time, these traditions and the rites that are related to their practice are categorised as “obscure” and considered unscientific by academia.

    The overall aim of this thesis was to advance the understanding of the different dimensions of plant use in the context of traditional religions in two western African countries: Benin and Gabon. First, by documenting the use of plants by adepts of Vodoun in Benin and Bwiti in Gabon; and second, by exploring the associated knowledge that sustains these practices. Its purpose was to contribute to an improved plant resource management and, ultimately, the development of culturally appropriate interventions aimed at the conservation of useful plant species and their ecosystems, as well as the improvement of human health in settings similar to those of our countries of study.

    Departing from the disciplinary perspective of ethnobotany, this work included theories and quantitative and qualitative methods of data collection and analysis drawn from botany, anthropology, ethnology, ecology, and pharmacology. Data were collected in a period of more than a year, which was divided in two fieldwork stays, each in Benin and Gabon.

    This thesis was organised into six chapters. In Chapter One, I laid out the conceptual framework and introduced the study sites. Based on an assessment of the relevance of this study, I framed its overall objective and research questions.

    Medicinal plants are not only acknowledged for their importance in satisfying the health needs of people in sub-Saharan Africa, but also for the role their commercialization plays as a source of income for vulnerable groups. In spite of this recognition, little is known about the implications of medicinal plant trade for the sustainability of the plant species involved, especially when data on the volume and diversity of species sold at the markets are not available. In Chapter Two, we addressed this gap by providing an estimation of the volume and economic value of the domestic market in herbal medicine in Benin. We also highlighted local health concerns reflected by the medicinal plant market and found that ritual plants were the largest use category for which vendors catered in the markets of Benin. Additionally, we suggested some species with possible sustainability issues.

    In Chapter Three, we explored the potential link between two different social mechanisms that regulate the use of plant resources (taboos and sacrifices) and the scarcity of ritual plants in Benin and Gabon. The scholarly discussion around the origin and necessity of taboos has found these to exist either as a means to avoid potential diseases or to control the use of natural resources. Moreover, empirical data has shown that taboos reflect resource abundance. These studies, however, have primarily focussed on the use of wild animals as food. By providing quantitative data based on questionnaires with local informants, we found evidence that restrictions (such as taboos and sacrifices) were an indication of resource scarcity of ritual plants, thus advancing new explanations to the existence of these social mechanisms.

    In Chapter Four, we revised two of the notions that are central to our study: ‘religion’ and ‘traditional religion’, this time as defined by the people who profess these faiths in Benin and Gabon. Plant use in the context of traditional religions has been commonly described from an outsider’s perspective. The same is true for religion and traditional religions. In this chapter, we learnt that plants played a central role in the religious traditions of Benin and Gabon, both for adepts and non-adepts of Vodoun and Bwiti.

    In Western science, the effects of ritual plants on human health have been proposed to be a matter of belief. In Chapter Five, we discussed the potential pharmacological effect of culturally salient and economically important ritual plants on their users. We did that by contrasting their mode of application to proven pharmacological properties gathered from the literature. Additionally, we described folk categories of illness related to supernatural agents (e.g. evil spirits, ancestors, and sorcerers), as well as diseases recognised by biomedicine but that are attributed supernatural causes by people in Benin and Gabon. We discovered that in both countries an important proportion of the ritual applications of plants suggest a pharmacological effect on their users.

    Finally, in Chapter Six, I addressed the research questions formulated in Chapter One and discussed our work’s methodological issues as well as its implications to other scientific disciplines. I also highlighted the possible applications of the research results in informing nature conservation and human development interventions, as well as some possibilities for future research. Moreover, I reached five conclusions about Bwiti and Vodoun in our countries of study: (1) Plants and other elements of the natural world play a central role in the religious traditions of Benin and Gabon, both for adepts and non-adepts of these traditions. (2) Social mechanisms such as taboos and sacrifices are a form of adaptive management of plant resources that respond to perceived scarcity of ritual plants by their users. (3) Ritual applications of plants used in our countries of study suggest a pharmacological effect on their users, as opposed to the previous assumption that their effectiveness is a matter of belief. (4) By being the backbone of the medinal plant trade in Benin and Gabon, ritual plants represent an important source of income for a substancial sector of the population of these two countries. (5) The Western notion of ‘ritual’ in the context of western African plant use is an important mechanism for the preservation and transmission of ecological, historical, and medicinal knowledge. These conclusions point to the need to question the assumptions upon which the study of plant use in the western African context has been typically approached. Finally, I concluded that as long as the exercise of agency by supernatural entities is acknowledged, considering these practices as ‘religious’ is justified from an etic perspective.

    In the period April - October 2011 Sibilla Laldi (MSc-student WUR) carried out the research project ‘Herbs in grasslands and health of the dairy herd’, a project of the Louis Bolk Institute. In this project the relation between pastures herbs and health of dairy cattle was studied on 22 dairy farms. An indicator was developed which combines the presence of individual herbs expressed as a percentage of pasture dry matter and the potential medicinal value of a herb. The results indicate that pasture herbs do contribute to animal health.

    In de periode april t/m oktober 2011 heeft Sibilla Laldi (MSc-studente WUR) voor het Louis Bolk Instituut het onderzoek ‘Kruidenrijk grasland en de gezondheid van melkvee’ uitgevoerd. In dit project is de relatie tussen een kruidenrijke weide en diergezondheid van melkvee onderzocht op 22 melkveebedrijven. Uit de resultaten blijkt dat kruiden een positieve bijdrage aan diergezondheid kunnen leveren wanneer ze in een bepaalde mate deel uit maken van het rantsoen. Er is een indicator ontwikkeld die het aandeel kruiden, op basis van droge stof, combineert met de potentiële medicinale werking. Er bleek een relatie te bestaan tussen deze nieuwe indicator en het antibioticagebruik op bedrijfsniveau (gemeten in dagdoseringen per dierjaar). Dit biedt perspectief om het aandeel kruiden in de weiden te bevorderen en hiermee o.a. het antibioticagebruik te reduceren. Het lijkt zinvol verder te onderzoeken welke kruiden onder Nederlandse omstandigheden een effectieve bijdrage aan de gezondheid melkvee leveren. De resultaten van dit project worden najaar 2012 wetenschappelijk gepubliceerd.
