In general, 8 patent applications were examined, of which 7 are directly associated with the species (and its derivatives) and 1 is related to a device specially designed for harvesting leaves/fruits and removing thorns. The focus of the patents was the use of the species in the food, pharmaceutical and biotechnological areas, with emphasis on the use of the leaves in the extraction of mucilage and proteins. CONCLUSION: This study showed that Pereskia aculeata Mill. is a technologically promising plant, because of its nutritional and medicinal composition, and it is important to encourage innovation and the development of new products with the species.

Nephroprotective effects of Lippia sidoides ethanolic extract against ischemia/reperfusion-induced acute kidney injury

Abstract Ischemia/reperfusion injury (I/R) is commonly related to acute kidney injury (AKI) and oxidative stress. Antioxidant agents are used to treat this condition. Lippia sidoides is a brazillian shrub with anti-inflammatory and anti-oxidative properties. Thus, the aim of this study is to evaluate the effect of Lippia sidoides ethanolic extract (LSEE) on in vivo and in vitro models of AKI induced by I/R. Male Wistar rats were submitted to unilateral nephrectomy and ischemia on contralateral kidney for 60 min via clamping followed by reperfusion for 48 h. They were divided into four groups: Sham, LSEE (sham-operated rats pre-treated with LSEE), I/R (rats submitted to ischemia) and I/R-LSEE (rats treated with LSEE before ischemia). Kidney tissues homogenates were used to determine stress parameters and nephrin expression. Plasma and urine samples were collected for biochemical analysis. I/R in vitro assays were evaluated by 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) and flow cytometry assays in Rhesus Monkey Kidney Epithelial Cells (LLC-MK2). The LSEE treatment prevented biochemical and nephrin expression alterations, as well as oxidative stress parameters. In the in vitro assay, LSEE protected against cell death, reduced the reactive oxygen species and increased mitochondrial transmembrane potential. LSEE showed biotechnological potential for a new phytomedicine as a nephroprotective agent.

Fluoride concentration in teas derived from Camellia Sinensis produced in Argentina.

To evaluate the fluoride concentration and pH of tea derived from Camellia sinensis produced and commercialized in Argentina. Forty-eight varieties of tea (black (n = 16), green (n = 21), red (n = 7), and white (n = 4)) commercialized in the form of leaves or tea bags were acquired. One bag or 2.0 ± 0.05 g of each product was infused for 5 min in 200 mL of distilled boiled water. The F- concentration was determined using an ion-selective electrode and pH was measured using a pH meter. The found fluoride concentrations ranged from 0.1 to 9.7 µg/mL and the pH ranged from 2.7 to 5.1. A higher fluoride concentration was observed in the leaves group (2.75 ± 2.65 µg/mL) compared to tea bags (1.10 ± 0.82 µg/mL) (p < 0.05). Regarding the type of tea, green and black tea were richer in F- than red and white tea. Fluoride and pH appeared not to be correlated (Pearson test). All the studied tea samples presented fluoride concentrations greater than the threshold recommended for drinking water. The pH proved to be low, which could be a risk for erosive tooth wear.

Salivary Fluoride Bioavailability after Brushing with Brazilian Red Propolis Dentifrice: A Clinical Study.

INTRODUCTION: Fluoride plays an important role in the control of dental caries, and currently new dentifrices are being associated with natural products. OBJECTIVE: This study aimed to evaluate the availability of fluoride in saliva samples after using a dentifrice incorporated with Brazilian red propolis (BRP, INPI Patent no. BR1020170110974) and to compare it to a conventional fluoridated dentifrice in healthy participants. METHODS: This study was conducted implementing a double-blind, randomized, controlled, and crossover design. Saliva samples of participants were collected at the following time points: 0 at baseline and 5, 15, 30, 45, and 60 minutes after brushing with each dentifrice. Salivary fluoride concentrations showed no statistically significant difference when comparing the two treatments (p > 0.05). All available fluoride concentrations in saliva decreased after one hour, with no significant difference between BRP and conventional fluoridated dentifrice treatment samples (p > 0.05). RESULTS: The results showed that there was no difference between the analyzed fluoride concentrations 1 hour after brushing with the different dentifrices. CONCLUSIONS: The results of this study suggest that the propolis incorporated in the dentifrice did not interfere with the kinetics and bioavailability of the fluoride ion in saliva samples, enabling its integration with the pharmaceutical formula and thereby promoting its anti-inflammatory and antimicrobial benefits without compromising the anticaries activity of the formulation.

Camellia sinensis in Dentistry: Technological Prospection and Scientific Evidence.

PURPOSE: This study aimed to evaluate reports of patents for oral care formulations, based on Camellia sinensis (C. sinensis), deposited and granted in intellectual property banks. METHODS: A survey was conducted through collection, treatment, and analysis of extracted information from patent reports selected. The documentary research was conducted in January 2021 on formulations with C. sinensis for dental applications, including since the first patent deposits until the current time. The risk of bias of clinical trials with these formulations was analyzed to verify the scientific evidence. The data extracted represent the distribution of the number of patents by banks, annual evolution of patent deposits, applicant of patents by country, distribution of patents according to International Patent Classification codes, and the types of patented products. RESULTS: Data and information from 20 selected patents were extracted. The United States Patent and Trademark Office (USPTO) and World Intellectual Property Organization (WIPO) were the banks with the largest number of patents for products/formulations with C. sinensis for oral care applications with 7 (35%) and 6 (30%) patent registrations, respectively. Other banks did not provide patents related to the search. Patents of compositions were the largest with 14 filings, and the remainder of formulations are represented specially by mouthwashes and toothpastes. As for clinical application, 18 patents were filed as products with antimicrobial and antibiofilm action, while 2 patents are directed to the treatment of xerostomia. In general, the aspects of the studies of clinical efficacy pointed to a low risk of bias. CONCLUSION: The study pointed out a small number of products protected by patents for Camellia sinensis for oral care indication, highlighting mainly mouthwash compositions and formulations. In the methodological parameters of clinical trials carried out with the formulations, the majority pointed out a low risk of bias.

Antimicrobial Efficacy of Propolis-Containing Varnish in Children: A Randomized and Double-Blind Clinical Trial.

Dental caries is a sugar-dependent condition common in childhood, which causes microbiological imbalance in dental biofilm. The present study evaluated the antimicrobial efficacy of a 2.5% Brazilian Red Propolis (BRP) dental varnish to prevent caries in children. Seventy-five children with high caries risk, aged between 36 and 71 months and with no caries, were assigned to three groups to receive varnish treatment containing 2.5% BRP, 1% chlorhexidine, or 5% fluoride. The varnish was applied to the occlusal surfaces of the deciduous second molars on the first day of treatment (D1), after 90 days (D90), and 180 days of the start of treatment (D180). Saliva was collected to assess S. mutans before each varnish application and 180 days at the end of treatment (D360). Values were expressed in log10 (CFU/mL). Statistics were performed by applying repeated measures of variance analysis, Tukey's multiple comparisons test, and paired t-test. In the first dilution (1 : 10), there was microbial load reduction at the following periods: BRP in D0-D90 (p < 0.05) and D0-D180 (p < 0.01); fluoride in D0-D90 (p < 0.001); and chlorhexidine in D0-D180 (p < 0.05). In the second dilution (1 : 100), there was microbial load reduction in the groups at the following periods: BRP in D0-D90 (p < 0.05) and D0-D180 (p < 0.01); fluoride in D0-D180 (p < 0.05), and chlorhexidine in D0-180 (p < 0.01) and D0-360 (p < 0.05). The 2.5% BRP dental varnish was effective in decreasing S. mutans colonies in saliva when used within 90 days.

Clinical and Antimicrobial Evaluation of Copaifera langsdorffii Desf. Dental Varnish in Children: A Clinical Study.

BACKGROUND: The objective of this study was to evaluate the clinical and microbiological efficacies of (C. langsdorffii) dental varnish in children at high risk of dental caries.. METHODS: This is a longitudinal, randomized, controlled clinical trial. Ninety high-risk caries-free children (ICDAS II = 0) were recruited and randomly divided into three groups: C. langsdorffii, chlorhexidine, or fluoride. The varnishes were applied on the second deciduous molars for three times: baseline (D0), after 90 days (D90), and after 180 days (D180). Saliva was collected on D0, D90, D180, and D360 to evaluate S. mutans reduction. Statistics were carried out by ANOVA, Tukey's test, and the paired t-test. RESULTS: Copaiba varnish demonstrated significant S. mutans reduction: D360 versus D0 (p < 0.0001), D180 versus D0 (p < 0.001), D360 versus D90 (p < 0.001), D180 versus D90 (p < 0.001), and D360 versus D180 (p < 0.05). Chlorhexidine varnish significantly reduced S. mutans at D180 versus D0 (p < 0.05). Fluoride reduced at D180 versus D0 (p < 0.001). CONCLUSIONS: Three annual applications of this varnish showed substantial antimicrobial activity against S. mutans and caries prevention for up to 12 months.

Development and Innovation on Dental Products in Argentina: A Technological Prospecting Based on Patents.

BACKGROUND: Argentina has progressed with industrialization in comparison to other Latin American countries and this process had a direct impact on the innovative capacity of the national economy. A constant search for market leadership, including the dentistry field and dental materials, stimulates the industries to launch new products daily. Inventions related to health researches are mostly protected by patents as intellectual property. A patent landscape analysis through searches in patent banks is a tool used to identify trends in different areas of innovations. OBJECTIVE: This study aims to identify and evaluate the scenario of research, development and innovation of dental products in Argentina by a technological prospecting based on patents. METHODS: A survey of patent documents was conducted by searching for deposited and granted patents of dental products. The search was carried out during January 2020 in the patent database of the National Institute of Industrial Property of Argentina (INPI-AR). The terms "dentistry", "buccal", "dental" and "oral" were used to select the titles and abstracts of patent application reports. The information extracted from patent reports was organized in tables and Figs using Fig.Pad Prism 6 software to evaluate the applications. RESULTS: A total of 363 patents were published from 1989 to 2016, mainly by international industries, 93.3% as patent invention and 3.0% as utility model applications on dentistry. Only two patents (0.5%) were deposited by universities, as the University of Melbourne (Patent number 20060102378) and Universidad Nacional del Nordeste (Patent number 20140104149), among which only the last one is national. Among the deposits, only 6.6% were granted; mostly were in force, denied or lost. According to the specialties, most patents were related to compositions (64.7%) and personal products (21.7%), also on dentistry/cariology (6.33%) and prostheses/implants (4.68%). CONCLUSION: In general, we find that most patent applications are related to the preventive area, personal products and compositions for formulations. Few dental patents deposits are currently available in Argentina, suggesting that the importation of products into the area remains large, which can make dental products more expensive. It is important to invest in technology-based companies to promote increased economic activity, being a consequence of an investment in knowledge creation and intellectual property to the Dentistry area.

The National Institute of Industrial Property (INPI-Brazil) had the highest number of deposits (5), followed by Espacenet (2) and Free Patents (2). C. Langsdorffii was highlighted as the most widely used species in the products and deposits of vehicles in formulations (3). All the patents in the search are A61K code for medical, dental or hygienic purposes. CONCLUSION: Most of the found patents are related to the area of Microbiology, specifically with application in Cariology. Brazil is represented by the INPI and presented the highest number of patent applications when compared to other intellectual property banks.

Dose-response Evaluation of Propolis Dental Varnish in Children: A Randomized Control Study.

BACKGROUND: Early childhood caries is a sugar-dependent disease with multifactorial modulating factors affecting deciduous dentition. It is defined as the presence of at least one decayed tooth, absence of a tooth due to caries or the existence of a temporary restoration in a tooth in a child between zero and 71 months of age. No BRP varnish was found in intellectual property banks, therefore it was registered and deposited with patent number BR1020160190142. OBJECTIVE: The objective of this study was to evaluate the dose-response concentration of alcoholic extract of Brazilian red propolis (BRP), in the form of dental varnish, against Streptococcus mutans (S. mutans) in children. METHODS: Twenty-four children, aged between 36 and 71 months, of both genders and without caries, were selected to participate in this pilot study and grouped randomly into four groups to receive different concentrations of BRP varnish (1%, 2.5%, 5% and 10%). The varnish was applied to the surface of all second deciduous molars. The antimicrobial activity was observed in saliva, which was collected in two phases: before applying the BRP varnish and after use. RESULTS: There was microbiological reduction of S. mutans in the oral cavity of the children in all the tested concentrations. The highest percentage reduction of S. mutans was observed at the concentration of 2.5% (P = 0.0443). CONCLUSION: The BRP extract in the form of dental varnish has antimicrobial activity against S. mutans and constitutes a possible alternative in the prevention of dental caries.

Dose-response evaluation of a copaiba-containing varnish against streptococcus mutans in vivo.

INTRODUCTION: Dental caries is the most prevalent disease in humans and its incidence is particularly high during childhood. The use of medicinal plants is a common practice in Brazil. OBJECTIVE: To evaluate the optimal antimicrobial concentration of Copaifera langsdorffii (copaiba) oil-resin, in the form of dental varnish, against Streptococcus mutans (S. mutans) in children. METHODS: Twenty-four children, caries-free, aged until 6 years old, were selected to participate in this study. The varnish was applied to the occlusal surfaces of all deciduous molars. The antimicrobial activity was analyzed in saliva, whose collection was conducted in two phases: before applying the copaiba varnish and after use to verify the instantaneous effectiveness of Copaifera langsdorffii dental varnish in the reduction of S. mutans. The microbiological analysis was repeated twice, establishing dilutions of 1:10 mL and 1:100 mL. RESULTS: Comparisons between different times within the same dilution were carried out by repeated measures analysis of variance (ANOVA) associated with Tukey's multiple comparisons test. Comparisons of conditions prior to and after treatment were performed using the t test for paired samples and it indicated that the 1% formulation promoted a more significant decrease in the number of S. mutans colonies (p = 0,0026). CONCLUSION: Copaiba oil-resin, in the form of dental varnish, has antimicrobial activity against S. mutans in all the concentrations studied. Further studies to identify the long-term activity and anticaries effect of this varnish are required to establish its use in caries prevention.

Medicinal plants of the Caatinga, northeastern Brazil: Ethnopharmacopeia (1980-1990) of the late professor Francisco José de Abreu Matos.

ETHNOPHARMACOLOGICAL IMPORTANCE: The Caatinga (semi-arid region), is an exclusively Brazilian biome. Considering the scarcity of ethnobotanical and ethnopharmacological studies in this region before the year 2000, this study presents data from ethnobotanical expeditions carried out between 1980 and 1990, by the late professor Francisco José de Abreu Matos (1924-2008). The information revealed in this present work are valuable and remained unpublished until now. MATERIALS AND METHODS: The objective was to organize, systematize and analyze ethnobotanical and ethnopharmacological data using ethnobotanical analytical techniques. The most cited native species in each use category were selected for literature review of the pharmacological studies related to their ethnomedicinal uses. RESULTS: Revision of the botanical nomenclature led to the botanical confirmation of 272 plants, of which 84 (30.9%) were reclassified. These represented 71 families and 220 genera that were cited 1957 times. 153 (56.3%) of these plant species are native to Brazil, of which 36 (23.4%) are endemic to the Caatinga. The use reports (RU) associated with these plants, according to the body systems (ICPC-2) in decreasing order of UR and the ICF values were respiratory system (93 species, 407 UR, ICF 0.77), digestive system (119 species, 373 UR, ICF 0.68), general and nonspecific symptoms (95 species, 219 UR, ICF 0.58), female genital system (60 species, 184 UR, ICF 0.68), skin (71 species, 156 UR, ICF 0.55), cardiovascular (50 species, 99 UR, ICF 0.50), blood and immune system diseases (46 species, 96 UR, ICF 0.53), urological (44 species, 88 UR, ICF 0.51), musculoskeletal (33 species, 80 UR, ICF 0.60), psychological (21 species, 71 UR, ICF 0.60), while others represent less than 10.0% of the UR. The most cited plants in the disease categories were Dysphania ambrosioides (28), Pombalia calceolaria (28) Hymenaea courbaril (26), Myracrodruon urundeuva (50), Brassica juncea subsp. integrifolia (16), Scoparia dulcis (22), Phyllanthus niruri (14), Egletes viscosa (25), Lippia alba (16), Erythroxylum vacciniifolium (9) and Salvia rosmarinus (21). The most prominent clades of the medicinal plants based on cluster analysis were the Lamiids (Euasterids)-497 UR and the Fabids (Eurosids I) - 468 UR. Association between certain phylogenetic clades and use-category were also observed and discussed. CONCLUSION: This study demonstrated a new approach in ethnopharmacology by mapping plant usages to diseases prevalent in a community from old ethnobotanical travel reports. In addition to revealing the therapeutic potential of Caatinga species using cluster analysis.

The molar mass peak was estimated to be 4.0×10(3)Da using gel permeation chromatography (GPC). Polarized light photomicrography of histological sections revealed the presence of inulin in the cortical parenchyma. The chemical composition of inulin was identified by 1D and 2D NMR and FT-IR spectroscopy and the findings were compared with the literature. This is the first time inulin has been identified on FT-IR and NMR for the species Pombalia calceolaria.

Percepção dos profissionais quanto à pertinência dos indicadores de saúde bucal em uma metrópole do Nordeste brasileiro / Perception by professionals on the relevance of the oral health indicators in a metropolis of the Brazilian northeastern

Estudo exploratório-descritivo, com abordagem quali-quantitativa, que buscou analisar a percepção dos profissionais quanto à pertinência dos indicadores de saúde bucal do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB) em Fortaleza, Ceará. A desmotivação, a descontinuidade no fornecimento de insumos odontológicos, o abandono do tratamento por parte do paciente, a cultura popular de que a gestante não pode realizar tratamento odontológico e a insegurança do profissional no manejo clínico relacionado à prótese dentária, ao atendimento à gestante, ao atendimento à urgência odontológica e ao diagnóstico de alteração da mucosa oral dos usuários foram problemas identificados na operacionalização desses indicadores e mencionados como interferência para o cumprimento de suas metas.

Exploratory-descriptive study, with qualitative and quantitative approach, which aims to analyze the perception by professionals on the relevance of oral health indicators of the National Program for Access and Quality Improvement of Primary Care (PMAQ-AB) in Fortaleza, Ceará. The demotivation, the discontinuity in providing dental inputs, the abandonment of treatment by the patient, the popular culture in which the pregnant cannot carry out the dental treatment and the insecurity of the professional in the clinical handling related to dental prosthesis, to the attendance of the pregnant, to the attendance of dental urgency and to the diagnosis of user's oral mucosa alteration were problems identified in the operationalization of these indicators and mentioned as interference for the fulfillment of their goals.

Phytochemical study guided by the myorelaxant activity of the crude extract, fractions and constituent from stem bark of Hymenaea courbaril L.

ETHNOPHARMACOLOGICAL RELEVANCE: Hymenaea courbaril L. (Caesalpinoideae) is used in Brazilian folk medicine to treat anemia, kidney problems, sore throat and other dysfunctions of the respiratory system, such as bronchitis and asthma, although such properties are yet to be scientifically validated. AIM OF THE STUDY: In order to give a scientific basis to support the traditional use of Hymenaea courbaril, this study was designed to evaluate antioxidant, myorelaxant and anti-inflammatory properties of the ethanol extract from stem bark and its fractions. The myorelaxant effect of astilbin, a flavonoid isolated from the bioactive ethyl acetate fraction (EAF), has also been evaluated. MATERIAL AND METHODS: In the present study ethanol extract from stem bark (EEHC) and fractions were analyzed using bioassay-guided fractionation. The following activities were investigated: antioxidant by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, myorelaxant on rat tracheal smooth muscle, and anti-inflammatory using ovalbumin-induced leukocytosis and airway hyperresponsiveness in rats. RESULTS: The results of the present investigation show that the whole extract of Hymenaea courbaril and some of its fractions strongly scavenged DPPH radical. The extract showed myorelaxant activity on rat trachea, being EAF its highest efficient fraction. Bio-guided study allowed the isolation of astilbin, a well-known flavonoid. The activity induced by this compound indicates that it may be partly responsible for the myorelaxant effect of EAF. EAF reduced contractions that depended on divalent cation inflow through voltage-operated Ca(2+) channels (VOCCs) or receptor-operated Ca(2+) channels (ROCCs), but it was more potent to inhibit VOCC- than ROCC-dependent contraction induced by Ca(2+) addition in ACh-enriched Ca(2+)-free medium. Oral pretreatment of antigen-challenged animals with EAF prevented airway hyperresponsiveness on KCl-induced contraction and reduced the number of total white cells, particularly eosinophils and neutrophils in bronchoalveolar lavage. CONCLUSIONS: This study provided scientific basis that Hymenaea courbaril presents potential antioxidant, myorelaxant and anti-inflammatory actions, which support its use in folk medicine to treat inflammatory airway diseases.

Diagnosis of public programs focused on herbal medicines in Brazil / Diagnóstico de los programas de fitoterapia, inscrita en el sistema de salud pública en Brasil

The present study is aimed to diagnose the current public programs focused on herbal medicine in Brazil where the following results can be observed. The main purpose of implementation of these programs was the demand of the users of medicinal plants and herbal medicines. The initiative of the implementation of these programs was related to the managers (58 percent). The difficulties in this implementation were due to lack of funding (90 percent) of the programs. In 80 percent of the programs, the physicians did not adhere to herbal medicine services due to lack of knowledge in the subject. Training courses were proposed (70 percent) to increase the adhesion of prescribers to the system. Some municipalities use information obtained from patients to assess the therapeutic efficiency of medicinal plants and herbal medicines. Of the programs underway, cultivation of medicinal plants was observed in 50 percent, and 67 percent of the programs adopted quality control. In most programs, this control is not performed in accordance with the legal requirements.

Este trabajo tiene como objetivo diagnosticar los programas de fitoterapia en actividad en Brasil, donde se pudo verificar los siguientes resultados. El motivo principal para la implantación de los programas fue la demanda de los usuarios de plantas medicinales y fitoterápicos. La iniciativa de la implantación de los programas está relacionada a los gestores (58 por ciento). Las dificultades en la implantación o están relacionadas a la falta de recursos financieros (90 por ciento) de los programas. En 80 por ciento de los programas, los médicos no adhirieron a los servicios de fitoterapia por falta de conocimiento del asunto. Cursos de capacitación fueron propuestos (70 por ciento) para aumentar la concordancia de los prescriptores al sistema. Parte de los municipios utiliza informaciones de los pacientes para la evaluación de la eficiencia terapéutica de las plantas medicinales y fitoterápicos. De los programas en actividad, 50 por ciento cultivan plantas medicinales y 67 por ciento realizan control de calidad. En la mayoría de los programas ese control no atiende a la legislación vigente.

Diagnosis of public programs focused on herbal medicines in Brazil.

The present study is aimed to diagnose the current public programs focused on herbal medicines in Brazil by means of in loco visits to 10 programs selected by means of questionnaires sent to 124 municipalities that count on herbal medicine services. The main purpose of the implementation of program programs is related to the development of medicinal herbs. 70% of them are intended for the production of herbal medicines and 50% are aimed to ensure the access of the population to medicinal plants and or herbal medicines. The initiative of the implementation of these programs was related to the managers (60%). The difficulties in this implementation were due to the lack of funding (100%) of the programs. In 60% of the programs, the physicians did not adhere to herbal medicine services due to the lack of knowledge of the subject. Training courses were proposed (80%) to increase the adhesion of prescribers to the system. Some municipalities use information obtained from patients to assess the therapeutic efficiency of medicinal plants and herbal medicines. Of the programs underway, cultivation of medicinal plants was observed in 90% and 78% of them adopt quality control. In most programs, this control is not performed in accordance with the legal requirements. The programs focused on medicinal plants and herbal medicines implemented in Brazil face some chronic problems of infrastructure, management, operational capacity and self-sustainability, which can be directly related to the absence of a national policy on medicinal plants and herbal medicines.

Farmacovigilância e reações adversas às plantas medicinais e fitoterápicos: uma realidade / Pharmacovigilance and adverse reactions to the medicinal plants and herbal drugs: a reality

Os fitoterápicos são utilizados por automedicação ou por prescrição médica e a maior parte não tem o seu perfil tóxico bem conhecido. Atualmente estão incorporados aos vários Programas de Fitoterapia como opção terapêutica eficaz e pouco custosa. A importância da inclusão dos fitoterápicos nos programas de farmacovigilância vem sendo reconhecida nos últimos anos por vários países da Europa, como Reino Unido e Alemanha, onde várias plantas foram submetidas à farmacovigilância e muitas delas foram retiradas do mercado devido a importantes efeitos tóxicos e risco para uso humano. O aumento no número de reações adversas reportado é possivelmente justificado pelo aumento do interesse populacional pelas terapias naturais observado nas últimas décadas. A farmacovigilância de plantas medicinais e fitoterápicos é uma preocupação emergente e através do sistema internacional será possível identificar os efeitos indesejáveis desconhecidos, quantificar os riscos e identificar os fatores de riscos e mecanismos, padronizar termos, divulgar experiências, entre outros, permitindo seu uso seguro e eficaz.

The herbal drugs are used by self-medication or by medical prescription and most of them do not have their toxic profile well know. Currently they are incorporate to the Phytotherapy Programs as an effective and little expensive therapeutic option. The importance of the inclusion of the herbal drugs in the pharmacovigilance programs has been recognized in the last years by several countries from Europe, like United Kingdom and Germany, where several plants were submitted to pharmacovigilance and many of them were removed from the market due to important toxic effects and risk for human use. The pharmacovigilance of medicinal plants and herbal drugs is an emergent concern and through the international system it will be possible to identify the ignored undesirable effects, to quantify the risks and to identify the risks factors and mechanisms, to standardize terms, to publish experiences, etc., allowing their safe and effective use.
