Book Review:

Natural Toxins - Natural Medicines The meaning of 'Pharmacognosy' is not widely known as the subject of this book, but it describes an area of great public interest and increasing scientific attention. The author describes pharmacognosy as the study of certain natural substances that find application in medicine, especially in plants. In this case, the Paracelsus dictum that 'only the dosage decides that a drug is not a poison' is especially important. Toxicologists will know many
For the plants and compounds listed here as natural products played, and continue to play, a significant role in both toxicology and medicine. While this work is mainly conceived as a textbook for undergraduates, it is a powerful and insightful source of knowledge for scientists at all stages of their careers. There are a number of main sources, far more than in the typical textbook, which will encourage researchers not to know the
Topic area for 'moving into' a wide variety of clinical subjects, from illicit treatments to alternative therapies. I believe that the section on flavonoids and phytoestrogens should be stronger in view of their considerable current interest as dietary components, but otherwise, coverage of other natural products is very important

Aside from revisions and additions to just a few chapters, a new edition of a textbook is often very similar to the previous one. This does not apply in this case, as those familiar with previous editions will notice that the book structure has changed and several new chapters have been included. The remainder of the text contains a detailed analysis of pharmacists' key natural ingredients, also referred to as 'crude.'

Drugs, ordered by their 'working' constituents' chemistry. Anyone who wants to learn more about such essential toxic substances as alkaloids and glycosides will find in these parts sufficient detail. It is taken not only by the chemistry of synthetic medicines but also by facets of culture, agriculture,
Manufacture, detection and mode of biological operation, offering a lot of interesting content for personal enjoyment and fodder for creating trivia quizzes! The connection between toxins and medicines is repeatedly mentioned in examples of the roles played by arrow poisons, such as Curare, providing muscle relaxants used in surgery and the development of ophthalmic drug physostigmine from the Calabar bean ordeal poison.

However, other chapters classify materials according to their taxonomy, biological activity or mode of use, and toxicologists have particular relevance to some of these chapters. Examples include valuable natural chemical foods, misuse drugs and toxic plants. Another chapter deals with natural compounds for cancer treatment. This form an important part of the medicinal armory to combat this disease corpus, and are a perfect example of how toxicity is harnessed for medical purposes. A series of chapters deal with the complementary and racial substances

Health medicine. Given the current concern regarding the possible toxic effects of such materials, the information given is likely to be of particular interest. Other sections of the book may be less of a concern to toxicologists and is Concerning quality management, cultivation of plant tissue and genetic elements of medicinal plants. The book has a lot of drawings but it's full of accurate facts too. The norm for typography is very high and I consider it quite good. 

Few mistakes. The chemical structures appeared a bit blurred in some places but were legible in every case. I consider this to be exceptional value at £ 40 for a hardback book with over 600 pages. It should be part of any one's reference sources library of bioactive natural substances.
