  • When the price of Ginseng advanced some years ago hundreds engaged in the business who knew little or nothing of farming, plant raising and horticulture. That they largely failed is not to be wondered at. Later many began in a small way and succeeded. Many of these were farmers and gardeners. Others were men who had hunted, trapped and gathered "seng" from boyhood. They therefore knew something of the peculiarities of Ginseng. It is from the experience of these men that this work is largely made up--writings of those who are in the business.

  • This is a book about plant chemistry written by a herbalist with no claims of being a chemist. Having a driving ambition to understand the nature of herbal medicines—in particular what makes them work—I delved head first into the previously alien world of atoms, molecules and bonds. Having learned enough to be engaged to teach the topic to budding herbalists and naturopaths, I set about formalising the teaching notes—the result is the original (1996) edition of this text.

  • Herbs and traditional medicines are being extensively used for healthcare in almost all the countries since times immemorial. Ancient religious texts are replete with references on the use of natural products with medicinal properties. Because of local beliefs and practices and also from cost considerations herbal medicines remain a popular mode of treatment in the developing countries. Even in the industrialised society the rising cost of prescription drugs and ensuing side effects of the treatment make it highly attractive to use the traditional medicine particularly for minor ailments....

  • This is a book about the most fearsome disease of modern times, which will strike every fourth citizen of a developed country sometime during his life: cancer. It is not a book about the prevention of cancer, but rather its treatment with plant-derived chemicals. It is an up-to-date and extensive review of plant genera and species with antitumor and antileukemic properties that have been documented in a strictly scientific sense.

  • When I was invited to write this book, little did I know the odyssey upon which I was about to embark. This is the first book to investigate and synthesize scientific data about psychoactive herbs relevant to the specialty of veterinary behavior. Many of the herbs discussed have impressive proof to substantiate their use; others, less so; some have no proof at all, at least not yet. Let us not forget the many mainstream medicines that are plant derived (e.g.

  • Ethnobotany studies the relationships between people and plants and includes various aspects of how plants are used as food, cosmetics, textiles, in gardening, and as medicine. In contrast, ethnopharmacology studies the pharmacological aspects of a given culture’s medical treatments and their social appeal, concentrating especially on the bio-evaluation of the effectiveness of traditional medicines.

  • Despite its importance in plant metabolism, no sequences of higher plant ATP-dependent phosphofructokinase (EC are annotated in the databases. We have purified the enzyme from spinach leaves 309-fold to electrophoretic homogeneity. The purified enzyme was a homotetramer of 52 kDa subunits with a specific activity of 600 mUÆmg )1 and aKmvalue for ATP of 81 lm.

  • The defensive function of the glucosinolate–myrosinase system in plants of the order Capparales results from the formation of isothiocyanates when glucosinolates are hydrolysed by myrosinases upon tissue damage. In some glucosinolate-containing plant species, as well as in the insect herbivore Pieris rapae, protein factors alter the outcome of myrosinase-catalysed glu-cosinolate hydrolysis, leading to the formation of products other than isothiocyanates.

  • Few members of the general public are fully aware of the extent to which the atomic age affects their everyday lives. For many, bombs and power plants are their only associations with the term. The uses and benefits of radioactive isotopes in medicine, agriculture, industry, and science are widespread, however, allowing us to perform many tasks more accurately, more simply, less expensively, and more quickly than would otherwise be possible. In many cases, biological tracers for example, there is no alternative.

  • In many countries, medicines are provided free to all patients in the public sector. Where this is the case, price data are not reported. In countries where medicines are only provided free to some groups of patients (e.g. children, the elderly), data on the price paid by those who are required to pay for their medicines are collected. In such cases, the price is the full price paid, even if patients themselves only pay part of this price. As indicated in Box 1.1, in WHO/HAI methodology medicine prices are reported as median price ratios or MPRs, which express median local...

  • Nitric oxide (NO) is a signaling molecule that affects a myriad of processes in plants. However, the mechanistic details are limited. NO post-transla-tionally modifies proteins by S-nitrosylation of cysteines. The soluble S-nitrosoproteome of a medicinal, crassulacean acid metabolism (CAM) plant,Kalanchoe pinnata, was purified using the biotin switch technique.

  • In plants, fatty acids (FA) are subjected to various types of oxygenation reactions. Products include hydroxyacids, as well as hydroperoxides, epox-ides, aldehydes, ketones and a,x-diacids. Many of these reactions are cata-lysed by cytochrome P450s (P450s), which represent one of the largest superfamilies of proteins in plants.
