Through a combination of instinct, observation, taste, and experience, ancient men and women treated illness by using plants, animal parts, and minerals that were not part of their usual diet. Ancient man learned by trial and error to distinguish useful plants with beneficial effects from those that were harmful or not effective, and also which combinations or processing methods had to be used to gain consistent and optimal results. This knowledge of plant-derived remedies developed gradually and was passed on by word of mouth from generation to generation. In the course of time, each community/tribe methodically collected information on medicinal plants and herbs and developed well-defined herbal pharmacopoeias. Indeed, well into the 20th century, much of the pharmacopoeia of conventional medicine was derived from the herbal lore of native peoples and even today many commonly used medicines are of plant origin. Medicinal plants therefore constitute a vital resource that can be harnessed for both health and socioeconomic benefits. Nevertheless, but for the high cost of modern medicines, limited national health budgets and inadequate health facilities, which have compelled many governments to reconsider the advantages of traditional health care systems, the sector has remained largely ignored. Interestingly, with the renewed interest in herbal medicine, there are now growing concerns about their quality, safety and efficacy due to poor methods of preparation, the heavy microbial load characteristic of plants harvested from the wild, non-standardised dosages and limited scientific evidence. In 1978, the World Health Assembly adopted resolution WHA31.33 on Medicinal plants which called upon WHO to coordinate the efforts of Member States to develop and apply scientific criteria and methods for proof of safety and efficacy of medicinal plant products, and develop international standards and specifications for identity, purity and strength, especially galenicals, and manufacturing practices. Resolution WHA41.19 on Traditional medicine and medicinal plants adopted in 1988 emphasised the need for international cooperation and coordination to establish a basis for the conservation of medicinal plants, in order to ensure that adequate quantities are available for the use of future generations. These resolutions formally brought the rational and sustainable use and conservation of medicinal plants into the arena of public health policy. Concerns have also been raised about the unregulated exploitation of Africa’s bio-resources, environmental degradation, deforestation, uncontrolled burning and poor agricultural practices leading to depletion of rare and threatened medicinal plant species. Unfortunately, for many countries in the WHO African Region, the necessary legislation for sustainable local production, conservation and protection of medicinal plant species, is limited and even where available, it is not enforced. For its part, the WHO has provided some tools and guidelines that countries could use to adapt to their specific situations to develop and utilize their indigenous systems of medicine. Of particular relevance here are the WHO Guidelines on Good Agricultural and Collection Practices; Guidelines on the conservation of medicinal plants and WHO Monographs on medicinal plants. Some countries in the African Region have since used these tools, adopted national policies on conservation of medicinal plants or cultivated new medicinal plant varieties and compiled inventories of scientific information on medicinal plants. Saving the African Region's medicinal plant resources vis-à-vis promoting the use of plant medicines for the treatment of diseases needs an effective, sustainable and coordinated strategy. It is against this background that I endorse this herbal pharmacopoeia developed by the West African Health Organisation, a specialized health institution of the Economic Community of West African States (ECOWAS), which summarises and reviews the evidence base for some selected medicinal plants common to the ECOWAS member states and also outlines the quality control criteria needed for ensuring their identity, purity, and quality. WAHO Page iv WEST AFRICAN HERBAL PHARMACOPOEIA WAHP It is my hope that the ECOWAS Herbal Pharmacopoeia will receive the highest level of patronage from all the member states to improve access to quality health care for the people of the sub-region. Dr Luis Gomes Sambo WHO Regional Director for Africa Brazzaville-Congo WAHO Page v WEST AFRICAN HERBAL PHARMACOPOEIA WAHP PREFACE The importance of traditional medicine in providing primary health care (PHC) was recognized by the Alma Ata Declaration adopted by the International Conference on PHC held at Alma Ata, USSR, in September 978. The Alma Ata Declaration called for “health for all by the year 2000”. This conference was followed in 1988 by another in Thailand, at which the Chiang Mai declaration to “save plants that save lives” was made. For economic reasons as well as cultural preferences, many Africans use traditional medicine for their health

  • Cherimoya and Guanabana in the Archaeological Record of Peru
    Journal of Ethnobiology 17(2):235-248 Winter 1997 CHERIMOYA AND GUANABANA IN THE ARCHAEOLOGICAL RECORD OF PERU THOMAS POZORSKI AND SHELIA POZORSKI Department of Psychology and Anthropology University of Texas-Pan American Edinburg, TX 78539 ABSTRACT.-Most researchers commonly assume that both cherimoya (Annona cherimolia) and guanabana (Annona muricata) have long been a part of the prehistoric record of ancient Peru. However, archaeological and ethnohistoric research in the past 25years strongly indicates that cherimoya was not introduced into Peru until ca. A.D. 1630 and that guanabana is only present after ca. A.D. 1000and is mainly associated with sites of the Chimu culture. RESUMEN.-La mayorfa de los investigadores suponen que tanto la chirimoya (Annona cherimola)como la guanabana (Annona muricata) han sido parte del registro prehist6rico del antiguo Peru por largo tiempo . Sin embargo, las in vestigaciones arqueol6gicas y etnohist6ricas de los ultimos veinticinco afios indican fuertemente que la chirimoya no fue introducida al Peru sino hasta 1630 D.C., Y que la guanabana esta presente s610 despues de aproximadamente 1000 D.C., Y esta asociada principalmente con sitios de la cultura chirmi. RESUME.- La plupart des chercheurs supposent couramment qu'une espece de pomme cannelle (Annonacherimolia)et le corossol (Annona muricata) ont faitpartie, pendant une longue periode, de l'inventaire prehistorique du Perou. Toutefois, les recherches archeologiques et ethnohistoriques des vingt-cinq dern ieres annees indiquent fortement que la pomme cannelle A. cherimolia ne fut introduite au Perou qu'aux environs de 1630 apr. J.-c. et la presence du corossol n'est attestee qu'en 1000apr.

    Available online at www.worldnewsnaturalsciences.com WNOFNS 20 (2018) 54-61 EISSN 2543-5426 Anatomical assessment of the fibers in the trunk of Alstonia boonei for some derived indexes J. E. Otoide*, P. O. Tedela, O. D. Akerele and D. O. Adetunji Department of Plant Science and Biotechnology, Faculty of Science, Ekiti State University, Ado-Ekiti, Nigeria *E-mail address: [email protected] ABSTRACT Derived anatomical indexes such as Runkel’s ratio, Flexibility coefficient and Felting power / Slenderness ratio of the fibers in the trunk of Alstonia boonei were assessed using standard procedures and formulas. Significant differences (P≤ 0.05) existed in the Runkel’s ratio and Flexibility coefficient of the fibers along the axial position of the trunk, whereas, along the radial position, the differences were not significant (P≤0.05). Conversely, the Felting power/ Slenderness ratio of the fibers along the axial and radial positions of the trunk were not significantly different (P≤0.05) from one another. Totals of 0.65 ± 1.33, 68.32 ± 15.39 and 39.89 ± 15.41 were the Runkel’s ratio, Flexibility coefficient and Felting power/Slenderness ratio of the fibers. In view of the results obtained in the present assessment, assertions confirming the suitability of the trunk of Alstonia boonei as alternative sources of raw material for pulp and paper production were made. Keywords: Fibers, mean, axial and radial positions, Runkel’s ratio, Flexibility coefficient, Felting power / Slenderness ratio, Alstonia boonei 1. INTRODUCTION Burkhill (1985) described Alstonia boonei De Wild. as a tall forest tree, which can reach 45 metres (148ft) in height and 3 metres (9.8ft) in girth, the bole being cylindrical and up to 27 metres (89ft) in height with high, narrow, deep-fluted buttresses.

Accepted 24 March, 2009 This paper presents the results of an assessment of the ethnobotanical uses of some plants recorded in upper Nyong valley forest implemented by the Cameroon wildlife conservation society project (CWCS). Forestry transects in 6 localities, followed by socio-economic study were conducted in 250 local inhabitants. As results, medicinal information on 140 plants species belonging to 60 families were recorded. Local people commonly use plant parts which included leaves, bark, seed, whole plant, stem and flower to cure many diseases. According to these plants, 8% are use to treat malaria while 68% intervenes to cure several others diseases as described on. There is very high demand for medicinal plants due to prevailing economic recession; however their prices are high as a result of prevailing genetic erosion. This report highlighted the need for the improvement of effective management strategies focusing on community forestry programmes and aims to encourage local people participation in the conservation of this forest heritage to achieve a sustainable plant biodiversity and conservation for future posterity.

  • Emmanuel Nicholas Abakah. Hypotheses on the Diachronic
    1 Hypotheses on the Diachronic Development of the Akan Language Group Emmanuel Nicholas Abakah, Department of Akan-Nzema, University of Education, Winneba [email protected] Cell: +233 244 732 172 Abstract Historical linguists have already established the constituent varieties of the Akan language group as well as their relationships with other languages. What remains to be done is to reconstruct the Proto- Akan forms and this is what this paper sets out to accomplish. One remarkable observation about language is that languages change through time. This is not to obscure the fact that it is at least conceivable that language could remain unchanged over time, as is the case with some other human institutions e.g. various taboos in some cultures or the value of smile as a nonverbal signal. Be that as it may, the mutually comprehensible varieties of the codes that constitute the Akan language group have evidently undergone some changes over the course of time. However, they lack adequate written material that can take us far back into the history of the Akan language to enable any diachronic or historical linguist to determine hypotheses on their development. Besides, if empirical data from the sister Kwa languages or from the other daughters of the Niger-Congo parent language were readily available, then the reconstruction of the Proto-Akan forms would be quite straightforward. But, unfortunately, these are also hard to come by, at least, for the moment. Nevertheless, to reconstruct a *proto-language, historical linguists have set up a number of methods, which include the comparative method, internal reconstruction, language universals and linguistic typology among others.
