Prospective Protective Effects of Arthrospira platensis Against Acetaminophen Induced Hepato-Renal Toxicity in Rats / Efectos Protectores Prospectivos de Arthrospira platnesis Contra la Toxicidad Hepatorrenal Inducida por Paracetamol en Ratas

SUMMARY: The toxic effects of acetaminophen appear primarily in the liver and kidney. The protective effect of blue green alga Arthrospira platensis on hepato-renal toxicity caused by acetaminophen was evaluated in male rats. The obtained results showed that subcutaneous injection of acetaminophen at a dose 120 &240 սl acetaminophen/kg by weight resulted in an observed elevation in the enzyme activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and Alkaline phosphatase (ALP), serum total lipids, total cholesterol, creatinine, total bilirubin, urea, nitric oxide (NO), L- malondialdehyde (MDA) and interleukins (IL-2 &IL-6). However, there is a decrease in the serum total protein, albumin and loss in antioxidant enzyme activities in liver including; superoxide dismutase (SOD), catalase (CAT) and glutathione reductase (GSH). This effect was found to be dose and time dependent. In spite of, pre- oral administration of Arthrospira platensis 1000 mg/kg .b. wt. prior acetaminophen injection succeeded to modulate the effect of the observed abnormalities caused by acetaminophen. Moreover, there were no remarkable changes in serum biomarkers of rats received Arthrospira platensis only at a dose of 1000 mg/kg by weight (group 2). The histopathological findings confirm the biochemical results that indicates the safety use of Arthrospira platensis at the selected dose in this study. Therefore, the present results clarified the protective effect of blue green alga Arthrospira platensis on oxidative stress, hepatic and nephrotoxicity induced by acetaminophen in male Wister rats.

Los efectos tóxicos del paracetamol aparecen principalmente en el hígado y el riñón. Se evaluó en ratas macho Wistar el efecto protector del alga verde azulada Arthrospira platensis sobre la toxicidad hepatorrenal causada por paracetamol. Los resultados obtenidos mostraron que la inyección subcutánea de paracetamol a dosis de 120 y 240 µl de paracetamol/kg, resultó en una elevación en las actividades enzimáticas de la aspartato aminotransferasa (AST), alanina aminotransferasa (ALT) y fosfatasa alcalina (ALP), lípidos séricos totales, colesterol total, creatinina, bilirrubina total, urea, óxido nítrico (NO), L- malondialdehído (MDA) e interleucinas (IL-2 e IL-6). Sin embargo, hay una disminución en la proteína sérica total, albúmina y pérdida en las actividades de las enzimas antioxidantes en el hígado, incluyendo; superóxido dismutasa (SOD), catalasa (CAT) y glutatión reductasa (GSH). Se encontró que este efecto era dependiente de la dosis y el tiempo. A pesar de la administración preoral de Arthrospira platensis 1000 mg/kg, la inyección previa de acetaminofeno logró modular el efecto de las anormalidades observadas causadas por el acetaminofeno. Además, no hubo cambios notables en los biomarcadores séricos de ratas que recibieron Arthrospira platensis solo a una dosis de 1000 mg/kg (Grupo 2). Los hallazgos histopatológicos confirman los resultados bioquímicos que indican la seguridad del uso de Arthrospira platensis a la dosis seleccionada en este estudio. Por lo tanto, los presentes resultados aclararon el efecto protector del alga verde azulada Arthrospira platensis sobre el estrés oxidativo, la toxicidad hepática y la nefrotoxicidad inducida por paracetamol en ratas Wistar macho.

Radioprotective Effect of Nigella Sativa Oil on Heart Tissues of Rats Exposed to Irradition

Abstract Background Various studies are ongoing related to the radioprotective agents. Herbal preparations are currently becoming popular because of their beneficial effects with fewer side effects compared to the synthetic/semi-synthetic medicines, and Nigella sativa oil (NSO) is only one of them. Objective To investigate NSO for its antioxidant effects on the heart tissue of rats exposed to ionizing radiation (IR). Methods Thirty six male albino Wistar rats, divided into four groups, were designated to group I (IR plus NSO group) that received both 5 Gray of gamma IR to total cranium and NSO; group II (IR alone group) that received IR plus saline, group III (control group of NSO) that received saline and did not receive NSO or IR; group IV (control group) that received only sham IR. Alterations in Total antioxidant status (TAS) and Total oxidant status (TOS), Oxidative stres index (OSI), Sulhydryl group (SH), Lipid hydroperoxide (LOOH), Paraoxonase (PON) levels, Arylesterase (ARE) and Ceruloplasmin (CER) activities in homogenized heart tissue of rats were measured by biochemical methods. Results In heart tissue of the rats in the IR alone group (group II) LOOH, TOS and OSI levels were found to be higher, ARE activity and TAS level were found to be lower than all of the other groups (p < 0.01). These results also support that IR increases oxidative stress and NSO's protective effect. Conclusion NSO would reduce the oxidative damage in the irradiated heart tissue in the experimental rat model.

Jugos de fruta y productos herbáceos como perpetradores de interacciones farmacocinéticas mediadas por enzimas metabolizadoras y transportadores de membrana. Relevancia en clínica / Pharmacokinetic interactions of fruit juices and herbal preparations

Drug disposition in the human body is strongly influenced by transporters and metabolizing enzymes expressed in key organs including intestine, liver and kidney. Since drugs and chemicals present in foods such as fruit juices and herb-based products are substrates of the above-mentioned proteins, there is a high probability of pharmacokinetic interactions. Findings from preclinical and clinical studies helped to characterize the mechanisms by which the components of fruit juices and herbs act as perpetrators of pharmacokinetic interactions. The aim of this review is to provide an overview of pharmacokinetic fruit juice- and herb-drug interactions that could be relevant in the clinical setting.

Estratégias terapêuticas e atualizações no tratamento de vitiligo / Therapeutic strategies and updates for treatment of vitiligo

O vitiligo é uma desordem dermatológica complexa, cuja patogênese ainda não é totalmente esclarecida. Apesar de não apresentar complicações funcionais no organismo dos pacientes acometidos, o vitiligo pode resultar em um grande impacto psicossocial. Desse modo, é importante que os médicos saibam como conduzir o tratamento dessa patologia. O objetivo deste estudo foi documentar as terapias disponíveis para o tratamento do vitiligo, assim como apontar pesquisas que relataram a utilização dessas opções terapêuticas e os dados resultantes. As terapias abordadas foram corticoides tópicos e sistêmicos, fototerapia e fotoquimioterapias, antioxidantes, imunomoduladores, fenilalanina, despigmentação, procedimentos cirúrgicos e novas abordagens. A monoterapia parece ser menos eficaz no tratamento do vitiligo. A associação de medicação tópica e/ou sistêmica com o uso da fototerapia ultravioleta B de banda estreita parece ser o padrão-ouro para a repigmentação da pele dos pacientes. Medicamentos novos estão em estudo, porém sua eficácia e o estudo dos possíveis efeitos colaterais, principalmente a longo prazo, têm que ser melhores investigados. É necessário que o médico dermatologista, em conjunto com o paciente, escolha a melhor terapia dentre as disponíveis, de acordo com critérios clínicos e a possibilidade de acesso ao tratamento pelo portador. O acompanhamento e a abordagem por uma equipe multiprofissional também são importantes. (AU)

Vitiligo is a complex dermatological disorder, whose pathogenesis has not yet been fully elucidated. Although it does not present functional complications in the affected patients' body, vitiligo can result in a great psychosocial impact. Therefore, it is important that physicians know how to conduct its treatment. This study aimed at documenting the available therapies for the treatment of vitiligo, as well as pointing out studies reporting the use of these therapeutic options and their resulting data. The therapies addressed were topical and systemic corticosteroids, phototherapy, and photochemotherapies, antioxidants, immunomodulators, phenylalanine, depigmentation, surgical procedures, and new approaches. Monotherapy appears to be less effective in the treatment of vitiligo. The combination of topical and/or systemic medication with the use of narrowband ultraviolet B phototherapy seems to be the gold standard for the patients' skin repigmentation. New drugs are under study, but their effectiveness and study of possible side effects, especially in the long run, have to be better investigated. It is necessary that the dermatologist, together with the patient, choose the best therapy among those available, according to clinical criteria and the possibility of access to treatment by the patient. Monitoring and approach by a multiprofessional team is also important. (AU)

Antiulcerogenic effects of selected African nightshades (Solanum nigrum Linn. ) genotypes on the rat stomach: a morphologic and morphometric study / Efectos antiulcerogénicos de genotipos seleccionados de solanáceas Africanas (Solanum nigrum Linn. m) en el estómago de ratas: un estudio morfológico y morfométrico

Solanum nigrum (SLN), commonly known as African nightshade, is used as a vegetable as well as in the management and treatment of various ailments including gastric ulcers. We analyzed, both grossly and microscopically using H&E, Masson's trichrome and PSA staining methods, the protective effects of aqueous leaf extracts of three Kenyan SLN genotypes namely S. scabrum (SSB), S. sarrachoides (SSR) and S. villosum (SVL) on ethanol-induced gastric lesions in rats. There was evidence of gastro-protection by all the three genotypes with the SSB showing the highest ulcer inhibition score (76.37 %) followed by SSR (72.51 %) and SVL (63.30 %). SLN-pretreated rats showed less areas of gastric mucosal surface erosion. Additionally in the pretreated animals, the depth of the ulcers were markedly reduced, reaching only the gastric pit region except in those treated with SVL where the ulcers penetrated slightly more deeply to affect the gastric glands. Compared with controls, the mean microscopic ulcer index decreased 5.07, 3.55 and 2.37-fold in rats pretreated with SSB, SSR and SVL extracts respectively. Results of this work show extracts of the three SLN genotypes to have antiulcerogenic potential but at varied strengths, thus confirming earlier reports that phytoconstituents and hence the efficacy of a medicinal plant may be influenced by genetic factors.

Solanum nigrum (SLN), comúnmente conocida como la solanácea africana, se usa como vegetal, para el tratamiento de diversas dolencias incluyendo las úlceras gástricas. Analizamos de forma macro y microscópica, de forma macroscópica y microscópica, utilizando para ello tinciones de H&E, tricrómico de Masson y PSA los efectos protectores de extractos acuosos de hojas de tres genotipos SLN de Kenia: S. scabrum (SSB), S. sarrachoides (SSR) and S. villosum (SVL) en lesiones gástricas inducidas por etanol en ratas. Hubo evidencia de gastroprotección por parte de los tres genotipos con el SSB mostrando el puntaje más alto de inhibición de la úlcera (76,37 %) seguido de SSR (72,51 %) y SVL (63,30 %). Las ratas tratadas previamente con SLN mostraron menos áreas de erosión de la superficie de la mucosa gástrica. Además, en los animales pretratados, la profundidad de las úlceras se redujo notablemente, llegando solo a la región del fondo gástrico, excepto en aquellos tratados con SVL donde las úlceras penetraron un poco más profundamente para afectar las glándulas gástricas. En comparación con los controles, el índice medio de úlcera microscópica disminuyó 5,07, 3,55 y 2,37 veces en ratas pretratadas con extractos de SSB, SSR y SVL, respectivamente. Los resultados de este trabajo muestran que los extractos de los tres genotipos de SLN tienen potencial antiulcerogénico en diferentes concentraciones, lo que confirma informes anteriores que los fitoconstituyentes y la eficacia de una planta medicinal pueden estar influenciados por factores genéticos.

Evaluación de la calidad microbiológica de productos naturales procesados de uso medicinal comercializados en Quito, Ecuador / Evaluation of the microbiological quality of natural processed products for medicinal use marketed in Quito, Ecuador

RESUMEN Objetivos: Determinar la calidad microbiológica de una muestra de productos naturales procesados de uso medicinal de libre comercio en Quito, Ecuador. Materiales y métodos: 83 productos se sometieron a recuentos de microorganismos aerobios, mohos y levaduras por técnicas convencionales estandarizadas, de acuerdo a la Farmacopea de los Estados Unidos (USP, por sus siglas en inglés). Se identificaron los microorganismos presentes y se determinó su sensibilidad antimicrobiana usando el método de difusión en agar. Resultados: El 17,0% de los jarabes, el 27,0% de los productos tópicos y el 43,0% de los sólidos orales excedieron los límites especificados para el recuento total de microorganismos aerobios, mientras que el 33,0% de los jarabes, el 7,0% de los productos tópicos y el 36,0% de los sólidos orales excedieron el límite para mohos y levaduras. Los productos de uso ocular no pasaron la prueba de esterilidad. El género bacteriano más frecuentemente aislado fue Bacillus, seguido por Escherichia coli, Klebsiella y Enterobacter. Salmonella ni Staphylococcus aureus se encontraron en ningún producto, pero microorganismos potencialmente patógenos como Pseudomonas se aislaron en el 40,0% de los colirios. Enterobacter y Escherichia coli mostraron resistencia a múltiples compuestos y Pseudomonas no fue resistente a ningún antibiótico. Conclusiones: La calidad microbiológica de los productos examinados no fue adecuada. Se aislaron microorganismos potencialmente patógenos y resistentes a antibióticos. Estos productos podrían no ser aptos para su distribución y consumo, aun cuando muchos de ellos cuenten con registro sanitario. El control y regulación por los entes responsables es indispensable.

ABSTRACT Objectives: To determine the microbiological quality of samples from processed natural products used for medicinal purposes and marketed in Quito, Ecuador. Materials and methods: Aerobic microorganisms, molds and yeasts were counted by conventional standardized techniques, according to the United States Pharmacopoeia (USP), in samples from 83 products. The microorganisms found were identified and their antimicrobial sensitivity was determined using the agar diffusion method. Results: The total aerobic microorganism count exceeded the specified limits in 17.0% of syrups, 27.0% of topical products and 43.0% of oral solids; the molds and yeasts count exceeded the limit in 33.0% of syrups, 7.0% of topical products and 36.0% of oral solids. Products for eye use did not pass the sterility test. The most frequently isolated bacterial genus was Bacillus, followed by Escherichia coli, Klebsiella and Enterobacter. Salmonella and Staphylococcus aureus were not found in any product, but potentially pathogenic microorganisms such as Pseudomonas were isolated in 40.0% of the eye drops. Enterobacter and Escherichia coli showed resistance to multiple compounds and Pseudomonas was not resistant to any antibiotic. Conclusions: The microbiological quality of the products examined was not adequate. Potentially pathogenic and antibiotic resistant microorganisms were isolated from the samples. These products may not be suitable for distribution and consumption, even though many of them have sanitary registration. Control and regulation by the corresponding authorities is essential.

Prescription to reduce heart palpitations, a mid-18th century prescription in the New Kingdom of Granada / Formulación para reducir las palpitaciones cardiacas, una receta médica de mediados del siglo xviii en el Nuevo Reino de Granada

Abstract The human being, throughout history, has used plants to prevent and cure diseases. It is important to know that for a long time, the mechanism through which those plants worked was unknown, making herbal medicine a purely empirical science. Medical prescriptions in the 19th century in the Kingdom of Nueva Granada were considered a significant medical advance as a result of knowledge and medical practices in the old continent. Medical literature of the time achieved, despite the lack of studies, the development of new schemes with exact dosages and new therapeutic possibilities. The medical prescription presented in this article was used in the management of heart palpitations, a frequent symptom nowadays, described as thoracic and/or neck beating, underlying various cardiac and non-cardiac diseases. The recipe for the palpitations of the historical archive "Cipriano Rodríguez Santa María" is a mixture of herbal agents that, as reviewed in the medical literature, showed to have anti-inflammatory, anxiolytic, and antioxidant effects, among others, allowing a beneficial effect on cardiac palpitations. Due to the lack of information on the posology, safety in its use, contraindications, and possible adverse effects, its potential use should have been underestimated at that time for the control of palpitations or as phytochemical agents directed to treat diseases causing this symptom.

Resumen A lo largo de la historia, el ser humano ha utilizado plantas para prevenir, aliviar y curar enfermedades. Cabe destacar que durante mucho tiempo se desconoció el mecanismo por el cual su uso era beneficioso, lo que hacía de la fitoterapia una ciencia netamente empírica. Las recetas médicas eran consideradas un avance médico significativo, resultado de conocimientos y prácticas traídas desde el viejo continente. Pese a la carencia de estudios locales, la literatura médica de la época permitió utilizar la biodiversidad de América para el desarrollo, investigación y uso de nuevos esquemas fitoterapéuticos con dosificaciones establecidas e indicaciones de uso, incluso un lugar específico de dispensación, ampliando aún más las posibilidades terapéuticas. La receta médica que se expone en este artículo era empleada en el manejo de las palpitaciones cardiacas, síntoma frecuente aún en la actualidad, descrito como golpes en tórax y/o cuello, subyacente en diversas enfermedades cardiacas y no cardiacas. La receta para las palpitaciones del archivo histórico Cipriano Rodríguez Santa María es una mezcla de agentes herbarios que, al realizar una revisión en la literatura médica, evidencian efectos antiinflamatorios, ansiolíticos y antioxidantes entre otros, sustentando un posible efecto beneficioso en las palpitaciones cardiacas. Debido a la ausencia de información sobre la posología, seguridad en su uso, contraindicaciones y posibles efectos adversos, es subestimado su potencial uso en aquel entonces para el control de las palpitaciones o como unos agentes fitoquímicos dirigidos para tratar enfermedades causantes de dicho síntoma.

Objetivo Avaliar a eficácia da Baccharis dracunculifolia (alecrim-do-campo) no tratamento da colite de exclusão em ratos. Método Utilizou-se 18 ratos Wistar, os quais foram anestesiados e submetidos à colostomia; em seguida distribuídos em 2 grupos: Grupo Controle, recebendo infusão intrarretal de solução salina (n = 8) e Grupo BD, recebendo infusão intrarretal de extrato de Baccharis dracunculifolia (n = 10); após 21 dias de tratamento foram submetidos a eutanásia, o segmento intesinal excluso de trânsito intestinal foi ressecado e submetido a estudo histopatológico classificando-se o grau de inflamação e grau de congestão vascular de 0 a 3. Resultados Verificou-se média de inflamação 2,7 no Grupo Controle vs. 2,1 no Grupo BD (p = 0,049), enquanto as médias de congestão vascular foram 2,3 e 2, respectivamente, nos grupos controle e BD (p = 0,1642). Conclusão A infusão intrarretal do extrato de Baccharis dracunculifolia minimizou significantemente o processo inflamatório na colite de exclusão de ratos submetidos à colostomia, sem alterar o grau de congestão vascular.

Effectiveness of the Aloe Vera extract in the treatment of fistula-in-ano / Eficácia do extrato de Aloe Vera no tratamento da fístula anal

Abstract Rationale: Considering that anal fistulae are still challenging regarding their treatment due to the risk of fecal incontinence in the most complex cases and the increasing use of phytotherapeutic drugs such as Aloe Vera in medicine, even with proven healing effectiveness, there is interest in researching this drug in the treatment of anal fistulae. Objective: To evaluate the efficacy of Aloe Vera extract in the treatment of anal fistulae in rats. Method: Thirty male Wistar rats weighing 250-300 g were submitted to anal fistula and after 30 days were divided into three groups: Control Group (GCo) (n = 5), Carbopol Group (GCa) (n = 5), and Aloe Vera Group (GAV) (n = 10). In the GCo no treatment was performed, while in the others a daily infusion of 0.3 mL of solution (Carbopol only in GCa and Carbopol plus Aloe Vera extract in the GAV) was performed through the external orifice of the fistula for 30 days. Afterwards, euthanasia was performed and specimens were removed for histological study. It was evaluated the closure of the fistulous tract, the area of the remaining tract, the inflammatory infiltrate and the degree of vascular congestion. The results were submitted to statistical treatment by Kruskall-Wallis test, considering p<0.05. Results: There was no complete closure of the fistulous tract in any of the animals. The mean area of the remaining tract was 847.2 µm in the GCo, 565.6 µm in the GCa and 377.8 µm in the GAV (p<0.05). The mean of the inflammatory infiltrate score was 2.4 in the GCo, 2.4 in the GCa and 2.3 in the GAV (p<0.05), while in the evaluation of vascular congestion, we observed a mean of 1.6 in the GCo, 1.4 in GCa and 1.1 in GAV (p<0.05). Conclusion: The extract of Aloe vera was able to reduce the lumen of the fistulous tract and reduce the degree of vascular congestion; however, it did not allow the complete closure of the fistulous tract nor diminished the inflammatory process.

Resumo Racional: Considerando que o tratamento das fístulas anais tem risco de incontinência fecal e o crescente uso do Aloe Vera na medicina, há interesse em se pesquisar este fármaco. Objetivo: Avaliar a eficácia do extrato de Aloe vera no tratamento das fístulas anais em ratos. Método: Utilizou-se 30 ratos Wistar, os quais foram submetidos à criação de fístula anal e após 30 dias distribuídos em três grupos: Controle (GCo), Carbopol (GCa) e Aloe Vera (GAV). No GCo nenhum tratamento foi realizado, enquanto nos outros realizou-se infusão diária de 0,3 mL de Carbopol GCa e Carbopol mais extrato de Aloe Vera no GAV por 30 dias. Foram retirados os espécimes para estudo histológico, avaliou-se o fechamento do trajeto fistuloso, a área do trajeto remanescente, o infiltrado inflamatório e o grau de congestão vascular. Resultados: Não houve fechamento completo do trajeto fistuloso em nenhum dos animais. A média da área do trajeto remanescente foi 847,2 µm no GCo; 565,6 µm no GCa e 377,8 µm no GAV (p<0,05). A média do escore de infiltrado inflamatório foi 2,4 no GCo; 2,4 no GCa e 2,3 no GAV (p<0.05), enquanto na avaliação da congestão vascular observou-se média 1,6 no GCo; 1,4 no GCa e 1,1 no GAV (p<0,05). Conclusão: O extrato de Aloe Vera foi capaz de diminuir o lumen dos trajetos fistulosos e reduzir o grau de congestão vascular, porém, não permitiu o fechamento completo dos trajetos fistulosos nem diminuiu o processo inflamatório.

Abstract Objective: To assess the antibacterial and smear layer removal ability of Trigonella foenum, Syzygium cumini, Terminalia chebula seed extracts against E. faecalis dentinal biofilm. Material and Methods: Agar well diffusion, micro broth dilution assay and time-kill curve assay were performed to determine the antibacterial activity. The ability of the herbal extracts to remove the smear layer on the root canal surface was assessed by scanning electron microscopy. Results: Antibacterial activity was observed for the extracts of S. cumini and T. chebula on E. faecalis dentinal biofilm and its planktonic counterparts. The smear layer was efficiently removed by the seed extracts of T. chebula alone. Seed extracts of T. foenum neither possessed antibacterial effect nor smear layer removal ability. Conclusion: The extracts of T. chebula seeds may replace conventional irrigant due to its antibacterial properties and smear layer removing the ability. The extracts of S. cumini may be used as an intracanal medicament as it exhibited a bactericidal effect against the E. faecalis dentinal biofilm following 18 hours of incubation.

Evaluation of wound healing effect of alginate film containing Aloe vera gel and cross-linked with zinc chloride

Abstract Purpose To develop a new wound dressing composed of alginate and Aloe vera gel and cross-linked with zinc ions. Methods The aloe-alginate film was characterized using scanning electron microscopy (SEM), swelling profile, mechanical properties, polysaccharide content and X-ray diffraction (XRD). Thirty Wistar rats were divided in two groups a) treated with aloe-alginate film and b) control (treated with sterile gauze). Wound contraction measurements and hystological analysis were performed on 7th, 14th and 21st days after wound surgery. Results The aloe-alginate film presented adequated mechanical resistance and malleability for application as wound dressing. There was no statistical difference in wound contraction between two groups. Histological assay demonstrated that aloe-alginate film presented anti-inflammatory activity, stimulated angiogenesis on proliferative phase and a more significant increased in collagen type I fibers and decreased type III fibers which promoted a mature scar formation when compared to control. Conclusions The aloe-alginate film showed adequate physicochemical characteristics for wound dressing applications. The in vivo assay demonstrated that aloe-alginate film enhanced the healing process of incisional skin wounds.

Análise dos programas de plantas medicinais e fitoterápicos no Sistema Único de Saúde (SUS) sob a perspectiva territorial / Analysis of medicinal plant and herbal medicine programs in the Unified Health System (SUS) from the territorial perspective

Resumo É expressivo o crescimento do número de programas de fitoterapia no SUS desde 2006, quando lançada a Política Nacional de Plantas Medicinais e Fitoterápicos. Como esses programas se distribuem no território e como expressam diversidades regionais? A pesquisa analisou como os usos do território condicionam a existência desses programas e como estes promovem maior sinergia técnica (saber local e saber universalizado) e política (estratégias e atores) na produção, circulação, distribuição e dispensação de plantas medicinais e fitoterápicos no sistema público de saúde. A análise envolveu referencial teórico da geografia crítica e saúde coletiva, revisão bibliográfica conceitual e temática, análise documental, levantamento de dados primários e secundários, destacando-se extenso trabalho de campo. Os resultados apontam que o crescimento dos programas foi acompanhado pela opção por fitoterápicos industrializados, concentrando-se espacialmente no Sul e Sudeste. Foram identificadas duas fases nesse processo: 1980-2008, caracterizada por ações mais horizontais ligadas a diversidades regionais; e 2008-atual, caracterizada por ações mais verticalizadas na escala nacional. Conclui-se: a Política Nacional possibilitou aumento do número de programas, mas pouco fomentou suas expressões regionais.

Abstract There has been significant growth in the number of municipal phytotherapy programs in the Unified Health System since the launch of the National Policy of Medicinal Plants in 2006. The aim of the research was to analyze how these programs are distributed throughout Brazil, how they express regional diversity and how land use can influence these programs and promote broad technical synergy (local knowledge and universal knowledge) and policy (strategy and actors) in the production, circulation, distribution and dispe sation of medicinal plants in the public health system. The analysis involved a theoretical framework of critical geography and public health, conceptual and thematic literature review, document analysis, survey of primary and secondary data along with extensive fieldwork. The results show that the growth of programs was accompanied by the choice of industrialized herbal medicines, spatially concentrated in the South and Southeast. Two phases were identified in this process: 1980-2008 characterized by horizontal actions linked to regional diversities; 2008 to the present characterized by verticalized actions on a national scale. The National Policy made it possible to increase the number of programs but did little to promote greater regional diversity.

O uso da fitoterapia durante a gestação: um panorama global / The use of phytotherapy during pregnancy: a global overview

Resumo Este artigo tem como objetivo realizar uma revisão integrativa da literatura sobre a prevalência do uso da fitoterapia durante a gestação. Foi realizado um levantamento nas bases de dados SciELO, Medline e Science Direct com os descritores "herbal and pregnancy", "plant and gestation" e seus correspondentes em português: "planta e gestação"; "erva e gravidez". Dentre os artigos publicados entre 2000 e 2015, 46 estudos clínicos preencheram os critérios de inclusão e exclusão e foram selecionados para esta revisão. Destes, 11 foram realizados na Europa, 10 na Ásia, 5 na África, 3 na Oceania, 16 na América e, apenas um, foi de caráter multinacional. Na maioria dos estudos (67,39%) o método utilizado foi o de entrevista. A prevalência do uso da fitoterapia descrita nas publicações foi muito variável. Ademais, a camomila, o gengibre, o alho, a menta e a equinácea foram as espécies mais utilizadas pelas gestantes. Os dados mostram que o uso da fitoterapia durante a gestação é uma prática disseminada entre mulheres de todo o mundo, independentemente das variáveis socioeconômicas e étnico-culturais que eventualmente possam distingui-las.

Abstract The scope of this study is to present an integrative review of the prevalence of the use of phytotherapy during pregnancy. A review of the topic was made by research in the Scielo, Medline and Science Direct databases using the following key words: "herbs and pregnancy," "plant and gestation," with their respective terms in Portuguese. Forty-six articles published between 2000 and 2015 met the study's inclusion and exclusion criteria and were included in this review. Of these, 11 were carried out in Europe, 10 in Asia, 5 in Africa, 3 in Oceania, 16 in America and only one of which was a multinational study. In most of these (67.39%), the interview method was used. A substantial variability in the prevalence of phytotherapy use was reported in the articles. In addition, camomile, ginger, garlic, mint and echinacea were the species most used by pregnant women. Despite the socioeconomic and ethnic-cultural variables among women worldwide, phytotherapy use during gestation is a widespread practice.
