Such a system would not only help to exclude preparations from herbs with known toxicity, but would also provide a valuable tool to improve HMP quality, particularly since health problems arising from use of HMPs are often due to contaminants rather than the declared ingredients (WHO, 2000; Mukherjee, 2002b).

Even in developed countries, clever wording and innuendoes can raise expectations of what using a product will achieve. In extreme cases, the incorrect species or part of the plant is used, but more often the material consists of the correct plant material with low amounts of the compounds considered to be responsible for the biological activity. triazole beta carboline derivatives as antidiabetic compounds formulations of active principles incorporated in slns "herbal formulation for the treatment of Therefore, the development of standardisation proce- dures for quality control through biological assays is significant but difficult (Bauer, 1998; Mukherjee, 2003b). Recent developments in quanti- fying and demonstrating synergism mathematically (Berenbaum, 1989) are likely to stimulate more research and for synergism in herbal extracts to be taken more seriously. Antidiabetic herbal formulation principles values Antidiabetic herbal formulation principles values Current status of Indian medicinal plants with WHO has developed a series of technical guide- lines relating to the quality control of herbal medi- cinal plants grown in commercial plantations.

Moreover, the administration form also differs based on the application pattern, e.g. Pharmacol Rev 41: 93-141. In traditional herbal medicines in the Indian subcontinent, the quality control aspect has been considered from inception by the religious experts or the medicine men using the herb for diseases, and later by the physicians known as vaidyas and hakims. Dora Akunyili: scourge of Nigerian drug counterfeiters. Focus Altern Complement Ther 12: 88-90. The WHO 2002 guidelines emphasise that opera- tions on different products should not be carried out simultaneously or consecutively in the same room unless there is no risk of cross-contamination and when dry materials are used in production, special precaution should be taken to prevent the generation and dissemination of dust. Much has been written in the past two decades on ‘biopiracy' in the context of traditional medicines and is discussed comprehensively in three special issues of Journal of Ethnopharmacology (volume 51, issues 1-3, 1996) and updated more recently (Soejarto et al, 2005). The methods followed for standardisation should be documented and the blending process should be adequately controlled and documented and should be tested for conformity to the established specification.

Newswire (2006). Conclusions Herbal medicinal products occupy a significant place in consumer consciousness in the developed world and are important in healthcare in most developing countries. The biomarkers may act in combination with other chemical entities, via poorly understood mechanisms of synergy or antagonism, to be respon- sible for the efficacy of the standardised extracts for any particular therapeutic area or disease (Mills and Kerry, 2000). In these situations, it is unlikely that the recommended dose of plant material will have sufficient amounts present for any clinical effect and, in some cases, it might be possible that resistance or immunity builds up.

These differences in regulatory status are caused by differences in tradi- tional use, in cultural and historical background, in scientific substantiation and in enforcement of current legislation (Bast et al, 2002). SCE drugs in mind and required studies in adsorption, metabolism and excretion are difficult to apply to HMPs.
Adverse event (AE) An AE is any untoward medical occurrence in a patient or clinical investigation subject who has been administered a pharmaceutical product but which does not necessarily have a causal relationship with this treatment.

Auditing notebooks for the interpretation of the tech- nical requirements of GAP to the specific situation of each farm are very important and these do not involve much investment and financial constraints as organisational burdens for farmers, especially those regarding the management of information. Documentation on traditional use may include: • proper identification of the botanical used • determination of parts used • preparation process of the botanical ingredients • formulation of the traditional product • mode (route, schedule, and dose) of administration of the preparation • indications of use of the botanical/preparation • traditional geographical areas and populations in which such use occurred • time span and extent of use of the botanical product • contraindications and adverse effects that have been associated with use in humans and animals. Any one specification batch should not be blended with other batches for the purpose of meeting specifications, except for standardisation of the content of the constituents with known pharmaceutical therapeutic effect. Medicinal claims are allowed in many developed countries for products licensed as medi- cines only but, in less-controlled environments, extravagant claims are made.

As evidence for the efficacy of extracts increases, the debate has intensified between viewing extracts of plants in their own right as medicines or of using them as sources for active compounds for develop- ment into more conventional single chemical entity (SCE) pharmaceuticals (Mills and Canter, 2007). Although these hazards have been denounced for more than two decades now, they continue to pose an occasional threat to public health (Gertmner et al, 1995; Shaw et al, 1995). Although long-standing experience may tell much about striking and predictable acute toxicity, it is a less reliable tool for the detection of reactions that occur uncommonly, develop very gradually or need a prolonged latency period, or that are inconspicuous (De Smet, 1995). Apart from these observations, the other important factors in establishing a history of safe use are the results of animal studies and obser- vations from human exposure (Walker, 2004).
