Conservation And Utilization Of Threatened Medicinal Plants

Medicinal plants are globally valuable sources of herbal products. Plant-based remedies have been used for centuries and have had no alternative in the western medicine repertoire, while others and their bioactive derivatives are in high demand and have been the central focus of biomedical research. As Medicinal plants move from fringe to mainstream with a greater number of individuals seeking treatments free of side effects, considerable attention has been paid to utilize plant-based products for the prevention and cure of human diseases. An unintended consequence of this increased demand, however, is that the existence of many medicinal plants is now threatened, due to their small population size, narrow distribution area, habitat specificity, and destructive mode of harvesting. In addition, climate change, habitat loss and genetic drift have further endangered these unique species. Although extensive research has been carried out on medicinal and aromatic plants, there is relatively little information available on their global distribution patterns, conservation and the associated laws prevailing. This book reviews the current status of threatened medicinal plants in light of increased surge in the demand for herbal medicine. It brings together chapters on both wild (non-cultivated) and domestic (cultivated) species having therapeutic values. Thematically, conventional and contemporary approaches to conservation of such threatened medicinal plants with commercial feasibility are presented. The topics of interest include, but not limited to, biotechnology, sustainable development, in situ and ex situ conservation, and even the relevance of IPR on threatened medicinal plants. We believe this book is useful to horticulturists, botanists, policy makers, conservationists, NGOs and researchers in the academia and the industry sectors.

A detailed discussion of the need to conserve medicinal plants and their environments.

This contributed volume provides a comprehensive, in-depth and subject-based reviews on the current status of active ingredients, sustainable use, biodiversity and conservation of certain endangered medicinal plants. The book also explores conventional and non-conventional biotechnological interventions for their biodiversity conservation. Medicinal plants have been used in worldwide as a major source of raw material for the traditional herbal healthcare practices as well as for drug discovery and development in pharmaceutical industry. The cumulative consequences of various human activities and environmental factors cause decline in the biodiversity of medicinal plants at an unprecedented rate worldwide. Thus, the overall understanding of ecology, species and genetic diversity along with assessment of the status of different threats and their impact on medicinal plants is crucial to sustain existing biodiversity, its utilization and conservation. All the latest advancements in the biotechnological approaches for the conservation research of endangered medicinal plants and the future perspectives have been described. This book provides comprehensive reviews spreading over about 25 chapters divided in three sections. The chapters of this book are written by recognized scientists in their respective fields which are useful to students, academicians, researchers, botanists, biotechnologists, policy makers, conservationists and industries interested in biodiversity conservation and medicinal plant research for the production of secondary metabolites.

Sustainable Uses and Prospects of Medicinal Plants presents information on less known and underexplored medicinal plant species in various regions of the world. The book investigates current advances in medicinal plant science and includes detailed information on the use of green nanotechnology, characterization of plants, conservation, revitalization, propagation, and pharmacological activities of selected plants. A volume in the Exploring Medicinal Plants series, it collects information on less known medicinal plant species in various regions of the world for documentation profiling their ethnobotany, developments in their phytochemistry, and pharmacological activities and provides an in-depth look at some specific herbal medicines of importance, threatened and less known species and addresses sustainable utilization and conservation of medicinal plants to ensure existence and use. Appropriate for plant and biodiversity conservation organisations, community leaders, academicians, researchers, and pharmaceutical industry personnel, the book comprises innovative works with information of what is expected to address sustainability in the future.

Medicinal and Aromatic Plants (MAPs) are among the group of plants that are threatened in Nigeria. The demand for the plant parts is increasing and majority of the medicinal plant products for sale in the markets come from the wild collections. The medicinal usefulness of these plants cut across their use in treating all forms of human diseases and deficiencies. The therapeutic uses of over fifty (50)medicinal plants described were described in this book, in addition to the listing and explanation on close to thirty (30) threatened medicinal plants in Nigeria. In addition, the advantages and disadvantages of cultivating medicinal plants were highlighted. This publication concludes by recommending the cultivation of highly demanded medicinal plants, among many other recommendations necessary for the sustainability of the nation's diversity and wealth of medicinal plants.

This volume brings together a collection of papers by some experts in medicinal plants. It is presented as a contribution to clarifying the many policy and technical issues associated with the conservation, use, production and trade of medicinal plants. This publication draws attention to the huge contribution of medicinal plants to traditional and modern health care systems, but also alert the readers on the many problems and challenges facing their sustainable development, such as: assessment and management of the medicinal plant resource base; best harvesting and processing practices; trade issues and aspects dealing with the intellectual property rights on traditional medicine by indigenous peoples. The use of this document will help raise the awareness on medicinal plants as an important forest resource, and will help ensure that medicinal plants are adequately included in forest conservation and utilization programmes.

Catalogues the 150 species of medicinal plants most commonly used in traditional Chinese medicine. The book, which was compiled in collaboration with the Institute of Chinese Materia Medica, was produced in an effort to communicate knowledge about herbal medicine that has accumulated over thousands of years, has been confirmed through both empirical experience and scientific evaluation, and yet has rarely been published outside the Chinese literature. The book also responds to increasing respect for the value of medicinal plants as a source of efficacious and inexpensive new drugs that offer an important alternative to chemically synthesized medicines. Each plant species is first documented by a full colour photograph taken under natural conditions during the flowering or fruiting season. Where relevant, a second photograph illustrates the plant parts from which the crude drug is extracted. Explanatory notes for each species cover botanical name and synonyms, Chinese name, English name, parts used, description of the plant, its habitat, and geographical distribution, and clinical indications and dosage. Some of the syndromes and clinical signs are described in traditional Chinese medical terminology. Information on indications and dosage is in keeping with theories for the prescription of medicinal plants taken from traditional Chinese pharmacology. To facilitate retrieval of information, plant species are indexed according to botanical names, English names, names in Chinese phonetic alphabet, and Chinese (Han) characters. The book, which was compiled for reference and educational purposes, includes a note advising readers of the dangers of self-treatment.
