Fundamentals of Pharmacognosy and Phytotherapy E-Book: Edition 3

Free sample

Pharmacognosy (the science of biogenic or nature-derived pharmaceuticals and poisons) has been an established basic pharmaceutical science taught in institutions of pharmacy education for over two centuries. Over the past 20 years though it has become increasingly important given the explosion of new drugs, phytomedicines (plant medicines), nutraceuticals and dietary supplements – all of which need to be fully understood, tested and regulated.

From a review of the previous edition:

‘Drawing on their wealth of experience and knowledge in this field, the authors, who are without doubt among the finest minds in pharmacognosy today, provide useful and fascinating insights into the history, botany, chemistry, phytotherapy and importance of medicinal plants in some of today’s healthcare systems. This is a landmark textbook, which carefully brings together relevant data from numerous sources and provides, in an authoritative and exhaustive manner, cutting-edge information that is relevant to pharmacists, pharmacognocists, complementary practitioners, doctors and nurses alike.’ The Pharmaceutical Journal

‘This is an excellent text book which provides fascinating insights into the world of pharmacognosy and the authors masterfully integrated elements of orthodox pharmacognosy and phytotherapy. Both the science student and the non-scientific person interested in phytotherapy will greatly benefit from reading this publication. It is comprehensive, easy to follow and after having read this book, one is so much more aware of the uniqueness of phytomedicines. A must read for any healthcare practitioner.’

This encyclopedic reference work on pharmacognosy covers the study of those natural substances, principally plants, that find a use in medicine. Its popularity and longevity stem from the book's balance between classical (crude and powdered drugs' characterization and examination) and modern (phytochemistry and pharmacology) aspects of this branch of science, as well as the editor's recognition in recent years of the growing importance of complementary medicines, including herbal, homeopathic and aromatherapy.No other book provides such a wealth of detail.A reservoir of knowledge in a field where there is a resurgence of interest - plants as a source of drugs are of growing interest both in complementary medicine fields and in the pharmaceutical industry in their search for new 'lead compounds'.Dr Evans has been associated with the book for over 20 years and is a recognised authority in all parts of the world where pharmacognosy is studied, his knowledge and grasp of the subject matter is unique.Meticulously referenced and kept up to date by the editor, new contributors brought in to cover new areas.New chapter on 'Neuroceuticals'.Addition of many new compounds recently added to British Pharmacopoeia as a result of European harmonisation.Considers development in legal control and standardisation of plant materials previously regarded as 'herbal medicines'.More on the study of safety and efficacy of Chinese and Asian drugs.Quality control issues updated in line with latest guidelines (BP 2007).
Cyclic nucleotides are intimately involved in the consequences of either stimulation or blockade of receptors; therefore, an understanding of the biochemistry of cyclic nucleotides ought to be important for pharmacologists. Pharmacology is a science that among other things investigates chemical compounds that affect the physiology of cells, tissues and organs. Frequently pharmacologists account for the effect of low concentrations of a drug upon a tissue by invoking the presence of a receptor upon the surface of the cell. Traditional pharmacologists excelled at identifying and classifying the properties of receptors. A. J. CLARK'S monograph in the earlier series of the Handbook of Experimental Pharmacology (CLARK 1937) summarized the mathematics underlying the traditional pharmacological approach towards receptors. By its nature, however, classic pharmacology provided little useful information about the intracellular events occurring as a consequence of occupying a receptor; for example, ALQUIST (1948) identified the beta-adrenocep tor, but he did not provide any insight into how stimulation of the receptor produces tissue-specific physiological responses. The discovery of cyclic AMP by RALL and SUTHERLAND (see RALL, Vol. I) led to biochemical investigations of many different receptors (including ALQUIST'S beta-adrenoceptor) that share a cyclic nucleotide as a common factor in the biochemical mechanisms that translate the occupancy of receptors into physiological effects. Ten years ago, in the introduction to their monograph on cyclic nucleotides, ROBISON et al. (1971) commented on the rapid growth of interest in cyclic nucleotides over the preceding years.
Healthcare professionals, including doctors, pharmacists and nurses, are often confronted with patients who use over-the-counter (OTC) herbal medicinal products and food supplements. While taking responsibility for one’s own health and treatment options is encouraged, many patients use these products based on limited (and sometimes inaccurate) information from non-scientific sources, such as the popular press and internet. There is a clear need to offer balanced, well-informed advice to patients, yet a number of studies have shown that, generally, conventionally trained health practitioners consider their knowledge about herbal medicinal products and supplements to be weak.

Phytopharmacy fills this knowledge gap, and is intended for use by the busy pharmacist, nurse, or doctor, as well as the ‘expert patient’ and students of pharmacy and herbal medicine. It presents clear, practical and concise monographs on over a hundred popular herbal medicines and plant-based food supplements. Information provided in each monograph includes:

• Indications
• Summary and appraisal of clinical and pre-clinical evidence
• Potential interactions
• Contraindications
• Possible adverse effects

An overview of the current regulatory framework is also outlined, notably the EU Traditional Herbal Medicinal Products Directive. This stipulates that only licensed products or registered traditional herbal medicinal products (THRs), which have assured quality and safety, can now legally be sold OTC. Monographs are included of most of the major herbal ingredients found in THRs, and also some plant-based
food supplements, which while not strictly medicines, may also have the potential to exert a physiological effect.

Pharmaceutics is one of the most diverse subject areas in all of pharmaceutical science. In brief, it is concerned with the scientific and technological aspects of the design and manufacture of dosage forms or medicines. An understanding of pharmaceutics is therefore vital for all pharmacists and those pharmaceutical scientists who are involved with converting a drug or a potential drug into a medicine that can be delivered safely, effectively and conveniently to the patient.

Now in its fourth edition, this best-selling textbook in pharmaceutics has been brought completely up to date to reflect the rapid advances in delivery methodologies by eye and injection, advances in drug formulations and delivery methods for special groups (such as children and the elderly), nanomedicine, and pharmacognosy. At the same time the editors have striven to maintain the accessibility of the text for students of pharmacy, preserving the balance between being a suitably pitched introductory text and a clear reflection of the state of the art.

This unique book explains in simple terms the commonly occurring chemical constituents of medicinal plants. The major classes of plant constituents such as phenols, terpenes and polysaccharides, are described both in terms of their chemical structures and their pharmacological activities. Identifying specific chemical compounds provides insights into traditional and clinical use of these herbs, as well as potential for adverse reactions.

Features include:

* Over 100 diagrams of chemical structures

* References to original research studies and clinical trials

* References to plants commonly used throughout Europe, North America and Australasia.

Written by an experienced herbal practitioner, The Constituents of Medicinal Plants seriously challenges any suggestion that herbal medicine remains untested and unproven, including as it does hundreds of references to original research studies and trials.

Designed as an undergraduate text, the first edition of this book became an essential desktop reference for health practitioners, lecturers, researchers, producers and anyone with an interest in how medicinal herbs work. This edition has been extensively revised to incorporate up-to-date research and additional sections, including an expanded introduction to plant molecular structures, and is destined to become a classic in the literature of herbal medicine.
