ABSTRACT
O mapa apresenta uma visão geral das evidências sobre os efeitos das Plantas Medicinais Brasileiras para desfechos em saúde. A partir de uma ampla busca bibliográfica foram incluídos no mapa 214 estudos de revisão sistemática. Todos os estudos foram avaliados, caracterizados e categorizados por um grupo de pesquisadores de Laboratório de Tecnologia de Produtos Naturais (LTPN) da Faculdade de Farmácia da Universidade Federal Fluminense. Principais Achados: â As revisões avaliaram o efeito de intervenções com 69 tipos de plantas organizadas em 4 categorias: cultivadas, nativas, exóticas e introduzidas no Brasil. â As intervenções foram associadas a 130 desfechos de saúde organizados em 17 grupos: Bem-Estar, Vitalidade e Qualidade de Vida, Câncer, Condições Patológicas, Dermatopatias, Doenças Cardiovasculares, Doenças Nutricionais e Metabólicas, Doenças Respiratórias, Doenças Reumáticas, Doenças Urogenitais, Dor, Fatores Biológicos, Gastroenteropatias e Hepatopatias, Indicadores Psicológicos e Comportamentais, Indicadores Metabólicos e Fisiológicos, Saúde Mental, Saúde Bucal e Saúde Reprodutiva. â No total foram 465 associações entre intervenções (as plantas) e desfechos de saúde, com destaque para as plantas cultivadas (251 associações, 54%). â O grupo dos desfechos "Saúde Mental" foi o que recebeu mais associações (66 associações, 14%), seguido do grupo "Saúde Bucal" (42 associações, 9%). â Quanto aos desfechos, destaque para: Transtornos de Ansiedade (20 associações), Demência (16 associações), Diabetes Mellitus (17 associações) e Distúrbios Menstruais (15 associações). â Dentre as plantas, destaque para: Ginkgo biloba (76 associações), Aloe Vera (50), Zingiber officinale (39), Panax ginseng (28) e Curcuma longa (23).

The map provides an overview of the evidence on the effects of Brazilian Medicinal Plants on health outcomes. Based on an extensive literature search, the map includes 214 systematic review studies. All studies were assessed, characterized, and categorized by a group of researchers from the Laboratory of Natural Product Technology (LTPN) at the Faculty of Pharmacy of the Federal Fluminense University. Key Findings: - The reviews evaluated the effects of interventions using 69 types of plants organized into 4 categories: cultivated, native, exotic, and introduced to Brazil. - The interventions were associated with 130 health outcomes organized into 17 groups: Well-being, Vitality and Quality of Life, Cancer, Pathological Conditions, Dermatopathies, Cardiovascular Diseases, Nutritional and Metabolic Diseases, Respiratory Diseases, Rheumatic Diseases, Urogenital Diseases, Pain, Biological Factors, Gastroenteropathies and Hepatopathies, Psychological and Behavioral Indicators, Metabolic and Physiological Indicators, Mental Health, Oral Health, and Reproductive Health. - In total, there were 465 associations between interventions (plants) and health outcomes, with a significant emphasis on cultivated plants (251 associations, 54%). - The "Mental Health" group received the most associations (66 associations, 14%), followed by the "Oral Health" group (42 associations, 9%). - Notable health outcomes included Anxiety Disorders (20 associations), Dementia (16 associations), Diabetes Mellitus (17 associations), and Menstrual Disorders (15 associations). - Among the plants, notable ones included Ginkgo biloba (76 associations), Aloe Vera (50), Zingiber officinale (39), Panax ginseng (28), and Curcuma longa (23). Implications for Practice and Research: - Considering the effects of interventions on health outcomes, the studies reported a positive or potentially positive effect for the majority (68%) of the associations (181 associations with a positive effect and 137 with a potentially positive effect); - Noteworthy are the positive or potentially positive effects reported for interventions with Ginkgo biloba on the outcomes of Dementia, Alzheimer's Disease, and Cognitive Performance (8, 7, and 7 associations, respectively); - In 87 associations, the intervention was reported to have "no effect" on the outcome (19.7%); - An inconclusive effect was reported for a small portion of the associations (9%), indicating a need for further research. No negative or potentially negative effects were reported. The effect was not reported for 19 associations; - It should be noted that this list is dynamic and may change with the publication of new studies.

The aim of this work was to evaluate the potential of the essential oil (EO) from Ocotea pulchella leaves as an alternative in the control of schistosomiasis. It was tested O. pulchella EO nanoformulation to assess its activity against adult Biomphalaria glabrata, their spawning and Schistossoma mansoni cercariae. Additionally, the EO chemical composition was investigated by gas-chromatography. Nanoemulsion were elaborated by the low energy method. The adult mollusks, their spawning and cercariae were placed in contact with nanoemulsion to calculate lethal concentrations. Myristicin, bicyclogermacrene and α-Pinene were the main substances in the EO. Nanoemulsion caused mortality of adult B. glabrata, its egg embryos and S. mansoni. These results suggest the use of this nanoemulsion as an alternative in the control of the schistosomiasis cycle.

Se probó una nanoformulación de AE de O. pulchellapara evaluar su actividad ante adultos de Biomphalaria glabrata, sus huevos y cercarías de Schistossoma mansoni. La nanoemulsión fue elaborada por el método de baja energía. Los moluscos adultos, sus huevos y cercarías se colocaron en contacto con la nanoemulsión para calcular concentraciones letales. Los compuestos mayoritarios en el AE fueron miristicina, biciclogermacreno y α-pineno. La nanoemulsión causó mortalidad en adultos de B. glabrata, sus huevos y a S. mansoni. Los resultados sugieren el uso de esta nanoemulsión como una alternativa en el control del ciclo de esquistosomiasis.

BACKGROUND This work describes a chemical study of the essential oil from leaves of Xylopia ochrantha, an endemic Annonaceae species from Brazil, and its activity against Biomphalaria species. Considering its poor solubility in aqueous medium, the essential oil was nanoemulsified to evaluate its action on controlling some mollusc species of genus Biomphalaria, snail hosts of Schistosoma mansoni that causes schistosomiasis, which mainly affects tropical and subtropical countries. OBJECTIVES The main aims of this work were to analyse the chemical composition of essential oil from X. ochrantha, and to evaluate the effect of its nanoemulsion on molluscs of genus Biomphalaria and their oviposition. METHODS Chemical analysis was performed by gas chromatography coupled to mass spectrometry. Nanoemulsions were prepared by a low energy method and characterised by particle size and polydispersity index. Biological assays evaluating the mortality of adult species of B. glabrata, B. straminea and B. tenagophila and their ovipositions upon contact with the most stable nanoemulsion during 24 and 48 h were performed. FINDINGS Chemical analysis by mass spectrometry revealed the majority presence of bicyclogermacrene and germacrene D in the essential oil. The formulation with a hydrophilic-lipophilic balance (HLB) of 9.26 was the most suitable for the oil delivery system. This nanoemulsion caused the mortality in B. tenagophila, B. straminea and B. glabarata of different sizes at levels ranging from 50 to 100% in 48 h. Additionally, the formulation could inhibit the development of deposited eggs. CONCLUSION Thus, these results suggest the use of nanoemulsified essential oil from X. ochrantha as a possible alternative in controlling some Biomphalaria species involved in the schistosomiasis cycle.
