Although practitioner-prescribed 'western' herbal medicine (phytotherapy) is a popular complementary therapy in the UK, no clinical studies have been reported on patient-orientated outcomes. The objective of this pilot study was to investigate the effects of phytotherapy on symptoms of osteoarthritis of the knee. A previous study of Chinese herbal medicine for the treatment of irritable bowel syndrome, published in the Journal of the American Medical Association,(1) acted as a model in the development of the protocol of this investigation. Twenty adults, previously diagnosed with osteoarthritis of the knee, were recruited from two Inner London GP practices into this randomized, double-blind, placebo-controlled, pilot study carried out in a primary-care setting. All subjects were seen in consultation three times by a herbal practitioner who was blinded to the randomization coding. Each subject was prescribed treatment and given lifestyle advice according to usual practice: continuation of conventional medication where applicable, healthy-eating advice and nutrient supplementation, Individualized herbal medicine was prescribed for each patient, but only dispensed for those randomized to active treatment - the remainder were supplied with a placebo. At baseline and outcome (after ten weeks of treatment), subjects completed a food frequency questionnaire and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) knee health and Measure Yourself Outcome Profile (MYMOP) wellbeing questionnaires. Subjects completing the study per protocol (n = 14) reported an increased intake of wholegrain foods (p = 0.045) and oily fish (p = 0.039) compared to baseline, but no increase in fruit and vegetables and dairy products intakes. There was no difference in the primary outcome measure of knee health assessed as the difference in the mean response (baseline-week 10) in WOMAC score between the two treatment groups. However, there was, compared with baseline, improvement in the active group (n = 9) for the mean WOMAC stiffness sub-score at week 5 (p = 0.035) and week 10 (p = 0.060) but not in the placebo group (n = 5). Furthermore, for the active, but not the placebo group, the mean WOMAC total and sub-scores all showed clinically significant improvement (>= 20%) in knee symptoms at weeks 5 and 10 compared with baseline. Moreover, the mean MYMOP symptom 2 sub-score, mostly relating to osteoarthritis (OA), showed significant improvement at week 5 (p = 0.02) and week 10 (p = 0.008) compared with baseline for the active, but not for the placebo group. This pilot study showed that herbal medicine prescribed for the individual by a herbal practitioner resulted in improvement of symptoms of OA of the knee.

There has been a great advance in the pharmacognosy field, which has increased the use of medicinal plants by health professionals and practitioners of folk medicine. This systematic review explored the history and the present day application of phytotherapeutic medicines. We searched the databases Cochrane Library, Embase, Lilacs, PubMed, Scielo and a specialized bibliography. We concluded that there are many therapeutic potentialities in the use of phytotherapeutic medicines and medicinal plants. We also concluded that despite the increasing number of publications in the field each year, there is still a lack of reviews and meta-analyses that could promote a better integration of the knowledge produced. In addition, research about pharmacological interactions and multidisciplinary studies may promote a quicker and safer process from the workbench up to the clinical trials.

Parasitic diseases constitute one of the main problems affecting livestock; however the use of chemical medicaments provides drug resistance residues in animal and environmental contamination. Changes in production concepts require that food must be produced in hygienic conditions, per healthy animals and that are not eliminating antibiotic residues, pesticides or other drugs. This scenario has favored organic production and the use of medicinal plants. For the control of endoparasites, several studies have published the benefits of Azadirachta indica A. Juss., Punica granatum Linn., Musa sp., Operculina hamiltonii G. DON., propolis, among others. However, despite the existence in- vitro studies that demonstrate the pharmacological properties of phytotherapics, there is still need for clinical trials to determine dosage and its effects in- vivo. Investigations of new bioactive natural substances can be of great value for the control of animal health and food safety, which is particularly important for organic production systems in which the use of chemical drugs is a limiting factor for certification.

Objective: A summary of main aspects from a Health Technology Assessment report on Traditional Chinese Medicine (TCM) in Switzerland concerning effectiveness and safety is given. Materials and Methods: Literature search was performed through 13 databases, by scanning reference lists of articles and by contacting experts. Assessed were quality of documentation, internal and external validity. Results: Effectiveness: 43 articles concerning 'gastrointestinal tract and liver' were assessed. The studies covering 7,436 patients were undertaken in China (35), Japan (3), USA (2) and Australia (3); 33/43 being controlled studies. 34/40 show significantly better results in the TCM-treated group. A comparison of studies on results of treatment based on a diagnosis according to TCM criteria and studies on results of treatment according to Western diagnosis shows that treatment based on TCM diagnosis improves the result. The comparison of treatment by individual medication and standard medication showed a trend in favor of individual medication. Safety: TCM training and practice for physicians in Switzerland are officially regulated. Side effects occur, but no severe effects have been registered up to now in Switzerland. TCM medicinals are imported; admission regulations are being installed. Problems due to production abroad, Internet trade, self-medication or admixtures are possible. Conclusion: The evaluation of the literature search provides evidence for a basic clinical effectiveness of TCM therapy. Severe side effects were not observed in Switzerland. Regulations for trading and use of medicinals prevent treatment risks. Further clinical studies in a Western context are required.

OBJECTIVES: Herbal medicine (phytotherapy) is widely used, but the evidence for its effectiveness is a matter of ongoing debate. We compared the quality and results of trials of Western phytotherapy and conventional medicine. STUDY DESIGN AND SETTING: A random sample of placebo-controlled trials of Western phytotherapy was identified in a comprehensive literature search (19 electronic databases). Conventional medicine trials matched for condition and type of outcome were selected from the Cochrane Central Controlled Trials Register (issue 1, 2003). Data were extracted in duplicate. Trials described as double-blind, with adequate generation of allocation sequence and adequate concealment of allocation were assumed to be of higher methodological quality. RESULTS: Eighty-nine herbal medicine and 89 matched conventional medicine trials were analyzed. Studies of Western herbalism were smaller, less likely to be published in English, and less likely to be indexed in MEDLINE than their counterparts from conventional medicine. Nineteen (21%) herbal and four (5%) conventional medicine trials were of higher quality. In both groups, smaller trials showed more beneficial treatment effects than larger trials. CONCLUSIONS: Our findings challenge the widely held belief that the quality of the evidence on the effectiveness of herbal medicine is generally inferior to the evidence available for conventional medicine.

Many alternative therapies are used as first aid treatment for burns, despite limited evidence supporting their use. In this study, Aloe vera, saliva and a tea tree oil impregnated dressing (Burnaid) were applied as first aid to a porcine deep dermal contact burn, compared to a control of nothing. After burn creation, the treatments were applied for 20 min and the wounds observed at weekly dressing changes for 6 weeks. Results showed that the alternative treatments did significantly decrease subdermal temperature within the skin during the treatment period. However, they did not decrease the microflora or improve re-epithelialisation, scar strength, scar depth or cosmetic appearance of the scar and cannot be recommended for the first aid treatment of partial thickness burns.

Throughout history there have been many different and sometimes bizarre treatments prescribed for burns. Unfortunately many of these treatments still persist today, although they often do not have sufficient evidence to support their use. This paper reviews common first aid and pre-hospital treatments for burns (water--cold or warm, ice, oils, powders and natural plant therapies), possible mechanisms whereby they might work and the literature which supports their use. From the published work to date, the current recommendations for the first aid treatment of burn injuries should be to use cold running tap water (between 2 and 15 degrees C) on the burn, not ice or alternative plant therapies.

Measurements were made of the intake of a WHO/UNICEF glucose-based and a rice cereal-based oral rehydration solution (ORS) by children with diarrhoea. Twenty children who presented to the Children's Outpatient Department at Port Moresby General Hospital with acute diarrhoea and mild dehydration were randomly assigned to an ORS and measurements were taken over the following 3 hours. For data analysis, the patients were paired by weight. Testing the means of the paired samples by t test showed that there was no significant difference between the amount of rice ORS and the amount of glucose ORS taken over 3 hours. The discovery of oral rehydration solution (ORS) for the treatment of diarrheal disease has been heralded as the most important medical discovery of the century. Cereal-based ORS is able to decrease stool output and the duration of diarrheal illness more than the standard glucose-based ORS, through the increased absorption provided by oligosaccharides without the imposition of a greater osmotic penalty. Moreover, the peptides in cereals enhance amino acid and water absorption, while providing nutritional benefits. UNICEF's glucose-based ORS is becoming more widely used in Papua New Guinea (PNG). 20 children aged 6-37 months (mean age, 15 months) who presented to the Children's Outpatient Department at Port Moresby General Hospital during September-October 1993 with acute diarrhea and mild dehydration were randomly assigned to receive either a rice-based ORS or standard glucose ORS, and measurements were taken over the following 3 hours. The patients were paired by weight for analysis. No statistically significant difference was found between the amount of rice ORS and the amount of glucose ORS taken over 3 hours.

The guardians of children brought to the Port Moresby General Hospital's Children's Outpatient Department with a chief complaint of diarrhoeal disease were questioned regarding their preference of glucose-based vs rice-based oral rehydration solution (ORS) in order to determine the acceptability of a rice-based ORS. Of the 93 guardians interviewed, greater than 60% preferred the glucose-based solution in its mixability, appearance and taste, and 65% initially reported that their children preferred the taste of the glucose solution. However, after a 30-minute trial, only 58% of children still preferred the glucose solution. In a country where diarrhoeal disease is a leading cause of child death and guardians are the primary health care providers, the acceptability of an ORS is critical to the morbidity and mortality of Papua New Guinea's children. Killing an estimated 2.9 million children annually, diarrheal disease is the second leading cause of child mortality worldwide. Diarrheal disease is also the second leading cause of child mortality in Papua New Guinea (PNG), killing an average 193 inpatient children per year over the period 1984-90. However, despite the high level of diarrhea-related mortality and the proven efficacy of oral rehydration therapy (ORT) in managing diarrhea-related dehydration, standardized ORT has been underutilized in PNG. The current glucose-based oral rehydration solution (ORS) does not reduce the frequency or volume of a child's diarrhea, the most immediate concern of caregivers during episodes of illness. Cereal-based ORS, made from cereals which are commonly available as food staples in most countries, better address the short-term concerns of caregivers while offering a superior nutritional profile. A sample of guardians of children brought to the Port Moresby General Hospital's Children's Outpatient Department complaining of child diarrhea were asked about their preferences on glucose-based versus rice-based ORS in order to determine the acceptability of a rice-based ORS. More than 60% of the 93 guardians interviewed preferred the glucose-based solution for its mixability, appearance, and taste. 65% initially reported that their children preferred the taste of the glucose solution. However, after a 30-minute trial, only 58% of children still preferred the glucose solution.

A fitoterapia e o uso de plantas medicinais fazem parte da prática da medicina popular, que diminuiu frente ao processo de industrialização nas décadas de 1940 e 1950, aumentando a busca, pela população, por terapias menos agressivas destinadas ao atendimento primário à saúde. Essa complementa o tratamento usualmente empregado para a população de menor renda. O objetivo deste trabalho foi analisar o conhecimento dos gestores e profissionais de saúde que atuam na atenção primária, sobre fitoterapia e uso de plantas medicinais, nos municípios de Cascavel e Foz do Iguaçu - Paraná. Para tanto, no período de fevereiro a julho de 2009, foi realizado estudo exploratório, descritivo, qualitativo, empregando como instrumentos de pesquisa entrevistas semiestruturadas e um questionário estruturado, auto aplicado, com perguntas fechadas, a fim de contemplar os seguintes aspectos: perfil dos profissionais; aceitabilidade quanto à implantação da fitoterapia na atenção básica; confiança nos tratamentos com fitoterápicos; capacitação e formação profissional relacionadas à fitoterapia, entre outros itens. Um dos gestores considerou recente o programa de fitoterapia. Indicadores de satisfação da população quanto ao uso dos fitoterápicos ou plantas medicinais ainda não existem. O gestor do município de Cascavel relatou interesse na implantação do programa. Os demais profissionais entrevistados, de maneira geral, relataram não haver recebido formação sobre o tema durante a graduação, nem mesmo dentro das UBS onde trabalham. Entre os profissionais entrevistados seis (60%) relataram o acesso às informações sobre fitoterapia através do conhecimento popular, uma (10%) formação na UBS, dois (20%) através de periódicos, quatro (40%) através de meio de comunicação, sendo que quatro citaram mais que uma das opções. Em Foz do Iguaçu, nas UBS onde a terapêutica está implantada, os profissionais relataram não terem sido consultados antes de sua implantação, e a avaliação das plantas utilizadas pelos pacientes atendidos ocorre somente através de avaliação objetiva e subjetiva do tratamento Para implantação da fitoterapia nas UBS desses dois municípios, é necessário capacitar os profissionais quanto ao tema, desde o cultivo até a prescrição, melhorando o uso racional desses medicamentos.

Crude polysaccharide extracts were obtained from aqueous extracts of the microalgae Chlorella stigmatophora and Phaeodactylum tricornutum. The crude extracts were fractionated by ion-exchange chromatography on DEAE-cellulose columns. The molecular weights of the polysaccharides in each fraction were estimated by gel filtration on Sephacryl columns. The crude polysaccharide extracts of both microalgae showed anti-inflammatory activity in the carrageenan-induced paw edema test. In assays of effects on the delayed hyper-sensitivity response, and on phagocytic activity assayed in vivo and in vitro, the C. stigmatophora extract showed immunosuppressant effects, while the P. tricornutum extract showed immunostimulatory effects.
