Interacciones potenciales entre productos herbolarios con fármacos hipoglucemiantes en adultos mayores con diabetes mellitus, en una zona rural mexicana / Potenciais interacções entre produtos à base de plantas e medicamentos hipoglicemiantes em adultos mais velhos com diabetes mellitus no Mexico rural / Potential interactions between herbal products with hypoglycemic drugs in older adults with diabetes mellitus in rural Mexico

Introducción: El 50% de la población mundial usa tratamientos alternativos como productos herbarios. El 20% los consume de manera simultánea con algún tratamiento farmacológico para el control la Diabetes Mellitus tipo 2; enfermedad prevalente en adultos mayores. Es escasa la información acerca de las interacciones medicamentosas que pudieran producirse, siendo responsables de más de 7,000 muertes al año. Objetivo: Identificar los productos herbarios de mayor consumo del Adulto Mayor con Diabetes Mellitus Tipo 2, en Chapulco, Puebla, México y describir las posibles interacciones medicamentosas entre fármaco hipoglucemiante ­ producto herbario reportados en la literatura científica. Metodología: Estudio observacional, prolectivo, transversal, descriptivo, en una población de 35 adultos mayores diabéticos, con edad promedio de 70±7 años. Para la identificación de los productos herbarios de uso común y sus aplicaciones terapéuticas se aplicó el cuestionario U-PLANMED. Resultados: Se identificaron 50 productos herbarios y 18 combinaciones entre estos a la vez. El 40% de los participantes consumen simultáneamente más de dos productos herbarios con uno o dos fármacos hipoglucemiantes. Entre los productos de mayor consumo se encuentran el nopal (Opuntia ficus-indica L.), la manzanilla (Matricaria chamomilla L.) y el zacate de limón (Cymbopogon citratus DC. Stapf.). Las interacciones medicamentosas potenciales identificadas, principalmente en estudios experimentales en animales, sugieren que, existe una acción hipoglucemiante del producto herbario al aumentar la capacidad orgánica sobre la secreción/liberación de insulina endógena. Conclusiones: Se ha evidenciado la presencia de interacciones medicamentosas ante el consumo simultaneo de fármacos prescritos para el control de la diabetes mellitus tipo 2 con productos herbarios. Es necesario que, los profesionales en atención a la salud identifiquen el uso de dichos productos y orienten a los adultos mayores sobre las posibles repercusiones en los niveles de glucosa ante el consumo.

Introduction: 50% of the world's population uses alternative treatments such as herbal products. Twenty percent use them in conjunction with some form of pharmacological treatment to control type 2 diabetes mellitus, a disease prevalent in older adults. There is little information on the drug interactions that may occur, which are responsible for more than 7,000 deaths per year. Objective: To identify the most consumed herbal products among older adults with type 2 diabetes mellitus in Chapulco, Puebla, Mexico, and to describe the possible drug-drug interactions between hypoglycemic drugs and herbal products reported in the scientific literature. Methodology: Observational, prospective, cross-sectional, descriptive study in a population of 35 diabetic older adults with a mean age of 70±7 years. The U-PLANMED questionnaire was used to identify commonly used herbal products and their therapeutic applications. Results: Fifty herbal products and 18 combinations of them were identified. Forty percent of the participants used more than two herbal products simultaneously with one or two hypoglycemic drugs. The most used products included prickly pear cactus (Opuntia ficus-indica L.), chamomile (Matricaria chamomilla L.), and lemon grass (Cymbopogon citratus DC. Stapf.). Potential drug-drug interactions identified mainly in experimental animal studies suggest that there is a hypoglycemic effect of the herbal product by increasing the organic capacity on endogenous insulin secretion/release. Conclusions: The presence of drug-drug interactions has been demonstrated with the simultaneous consumption of drugs prescribed for the control of type 2 diabetes mellitus with herbal products. It is necessary for health care professionals to recognize the use of such products and to inform older adults about the possible repercussions on glucose levels when consuming them.

Introdução: 50% da população mundial utiliza tratamentos alternativos como os produtos à base de plantas. Vinte por cento utilizam-nos em conjunto com algum tipo de tratamento farmacológico para controlar a diabetes mellitus tipo 2, uma doença prevalente em adultos mais velhos. Há pouca informação sobre as interacções medicamentosas que podem ocorrer e que são responsáveis por mais de 7.000 mortes por ano. Objetivos: Identificar os produtos fitoterápicos mais consumidos entre os idosos com diabetes mellitus tipo 2 em Chapulco, Puebla, México, e descrever as possíveis interações medicamentosas entre medicamentos hipoglicemiantes e produtos fitoterápicos relatados na literatura científica. Metodologia: Estudo observacional, prospetivo, transversal e descritivo numa população de 35 idosos diabéticos com uma idade média de 70±7 anos. O questionário U-PLANMED foi utilizado para identificar os produtos fitoterápicos mais utilizados e suas aplicações terapêuticas. Resultados: Foram identificados 50 produtos à base de plantas e 18 combinações dos mesmos. Quarenta por cento dos participantes utilizaram mais de dois produtos à base de plantas em simultâneo com um ou dois medicamentos hipoglicemiantes. Os produtos mais utilizados foram o cato de figo da Índia (Opuntia ficus-indica L.), a camomila (Matricaria chamomilla L.) e o capim-limão (Cymbopogon citratus DC. Stapf.). As potenciais interacções medicamentosas identificadas principalmente em estudos experimentais em animais sugerem que existe um efeito hipoglicémico do produto à base de plantas através do aumento da capacidade orgânica na secreção/libertação de insulina endógena. Conclusões: A presença de interacções medicamentosas foi demonstrada com o consumo simultâneo de medicamentos prescritos para o controlo da diabetes mellitus tipo 2 com produtos à base de plantas. É necessário que os profissionais de saúde reconheçam o uso de tais produtos e informem os idosos sobre as possíveis repercussões nos níveis de glicose ao consumi-los.

Seasonal effect on phenolic content and antioxidant activity of young, mature and senescent leaves from Anredera cordifolia (Ten. ) Steenis (Basellaceae) / Efeito sazonal no conteúdo de fenólicos e ação antioxidante de folhas jovens, maduras e senescentes de Anredera cordifolia (Ten. ) Steenis (Basellaceae)

Anredera cordifolia (Ten.) Steenis is a vine species native to Brazil that is considered an unconventional food plant and a medicinal species whose phenolic compounds exert antioxidant activity. Since the production of metabolites is determined by environmental factors and leaf maturity, it is important to track these changes in order to determine the best time to harvest. This study aimed to verify whether leaf phenology and seasonality cause variations in the amount of phenolic compounds and in the antioxidant activity of this species. The leaves were collected in different seasons between September 2018 and April 2019, and separated according to maturity: young, mature, and senescent. Daily atmospheric temperature and rainfall data were used to characterize the collection period. The total phenolic content (TPC), determined by Folin-Ciocalteu method, was significantly higher in the young leaves collected in winter, a season of lower temperatures. These leaves showed 54.4 mg of gallic acid equivalents per 100 g of dry matter (mg GAE 100 g-1DM). Other results averaged 25.6 mg GAE 100 g-1DM. The highest antioxidant activity, assessed via the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, regardless of leaf phenology, was observed in leaves harvested in autumn (73.7%) and winter (71.1%), seasons with lower rainfall. Leaves harvested in summer and spring had lower antioxidant action rates (54.3 e 37.5%, respectively). There was no significant correlation between the total phenolic content and antioxidant activity. Thus, the phenolic composition of A. cordifolia, and consequently its activity on free radicals, varies seasonally in response to temperature and rainfall, and may or may not interact with the age of the leaves.

Anredera cordifolia (Ten.) Steenis é uma trepadeira nativa do Brasil considerada uma planta alimentícia não convencional e uma espécie medicinal, cujos compostos fenólicos exercem ação antioxidante. Como a produção de metabólitos é determinada por fatores ambientais e pela maturidade das folhas, é importante acompanhar essas mudanças a fim de determinar a época de colheita. Neste estudo objetivou-se verificar se a fenologia foliar e a sazonalidade ocasionam variação na quantidade de compostos fenólicos e na ação antioxidante dessa espécie. As folhas foram coletadas em diferentes estações, entre setembro de 2018 e abril de 2019, e separadas conforme a maturidade: jovens, maduras e senescentes. Os dados diários de temperatura atmosférica e pluviosidade foram usados para caracterizar o período de coleta. O conteúdo de fenólicos totais (TPC), determinado pelo método Folin-Ciocalteu, foi significativamente maior nas folhas jovens coletadas no inverno, período caracterizado por temperaturas mais baixas. Estas folhas apresentaram 54,4 mg equivalentes de ácido gálico por 100 g de matéria seca (mg GAE 100 g-1DM) . A média dos outros resultados foi de 25,6 mg GAE 100 g-1DM. A maior ação antioxidante, avaliada pelo método do radical livre 2,2-difenil-1-picrilhidrazil (DPPH), foi observada em folhas colhidas no outono (73,7%) e inverno (71,1%), independentemente da fenologia foliar. Nestes períodos a pluviosidade foi menor. Folhas colhidas no verão e na primavera apresentaram menores percentuais de ação antioxidante (54,3 e 37,5%, respectivamente). Não houve correlação significativa entre o conteúdo de fenólicos totais e a atividade antioxidante. Conclui-se que a composição fenólica de A. cordifolia e, consequentemente, sua ação sobre radicais livres, varia sazonalmente em resposta à temperatura e pluviosidade, podendo ou não interagir com a idade das folhas.

Conclusiones: Las plantas medicinales abordan un amplio espectro de usos y propiedades que necesitan un extenso estudio para su registro y divulgación.

Introduction: The use of medicinal plants is part of the traditional culture of many populations around the world. Used to prevent diseases and preserve the health of individuals, it is a knowledge that mothers and grandmothers keep for early childhood care. However, there are many gaps in research regarding the use and properties of medicinal plants in infants and the general population. Objective: Analyze and describe the practices and beliefs with the ancestral use of medicinal plants in infants by the Raizal community in San Andrés Island. Materials and methods: It's a qualitative study with a descriptive ethnographic design applied to a convenience sample of 8 grandmothers from the Raizal community of San Andrés Island. We made out a description and analysis of the ideas, social practices, behaviors, beliefs, meanings, and knowledge about the uses of medicinal plants on infants. Results: The ancestral knowledge of medicinal plants use led by the grandmothers still persevered. The use of medicinal plants on infants administers only to the need of health situations. The investigation found 23 specimens of medicinal plants used in infant breastmilk, just a few plants found in this study are registered in the Colombian Vademecum of medicinal plants. Discussion: The findings agree with the results of other studies that show the importance of cultural traditions in the care of infants, the role of the accumulated experience of grandmothers in this knowledge and practices. In addition to corroborating that the use of medicinal plants in infants is governed solely by the need for care in health situations that warrant it. Only two specimens of the medicinal plants classified by the Raizal women in this study are referenced in the Colombian Vademecum of medicinal plants. Conclusion: Medicinal plants address a wide spectrum of uses and properties that need extensive study for their registration and dissemination.

Protective Effect of Mormodica balsamina Leaf Extract on the Gastric Morphology of Experimental Rats Against Ethanol Induced Gastric Ulcers / Efecto Protector de los Extractos de Hojas de Mormodica balsamina en la Morfología Gástrica de Ratas Experimentales Contra Úlceras Gástricas Inducidas por Etanol

SUMMARY: Mormodica balsamina is a valuable medicinal plant that is used to treat wounds and inflammation; its leaves are also used as an antibiotic and in the treatment of stomach pain. This study was conducted to determine the anti-ulcer activity of methanolic leaf extract of Mormodica balsamina on ethanol-induced ulcer in albino rats. A total of 32 rats were used for the study. Groups I and II served as the baseline and negative controls respectively, while groups III-VII served as the test groups. Group I was untreated, while group II received 1ml/kg body weight of the vehicle (2 % DMSO). Three test groups (III - V) received methanol extracts (75 mg, 150 mg, 300 mg/kg body weight respectively) while the other three test groups (VI - VIII) received aqueous extracts (75 mg, 150mg, 300 mg/kg body weight respectively) via oral gavage for seven days prior to ulcer induction. The rats were sacrificed, stomachs excised and ulcers scored. Histological sections were produced and examined. Findings revealed that M. balsamina extracts protected the rats' gastric epithelia from ethanol induced ulceration to varying degree with the high dose (150 and 300 mg/kg) of both extracts offering the best preservation (42 % and 50 % ulcer protective index respectively) when compared to untreated animals. Histological findings correlated with calculated ulcer indices, with treated animals having less severe gastric mucosal lesions. In conclusion, extracts of M. balsamina may possess reasonable antiulcer activities in rats against ethanol induced gastric ulcer.

Mormodica balsamina es una valiosa planta medicinal que se utiliza para tratar heridas e inflamaciones; sus hojas también se utilizan como antibiótico y en el tratamiento del dolor de estómago. Este estudio se realizó para determinar la actividad antiulcerosa del extracto metanólico de hojas de Mormodica balsamina sobre la úlcera inducida por etanol en ratas albinas. Se utilizaron un total de 32 ratas para el estudio. Los grupos I y II sirvieron como referencia y controles negativos respectivamente, mientras que los grupos III-VII sirvieron como grupos de prueba. El grupo I no se trató, mientras que el grupo II recibió 1 ml/kg de peso corporal del vehículo (2% de DMSO). Tres grupos de prueba (III - V) recibieron extractos de metanol (75 mg, 150 mg, 300 mg/ kg de peso corporal respectivamente) mientras que los otros tres grupos de prueba (VI - VIII) recibieron extractos acuosos (75 mg, 150 mg, 300 mg/kg de peso corporal respectivamente) por sonda oral durante siete días antes de la inducción de la úlcera. Se sacrificaron las ratas, se extirparon los estómagos y se puntuaron las úlceras. Se realizaron y examinaron secciones histológicas. Los resultados revelaron que los extractos de M. balsamina protegieron el epitelio gástrico de las ratas de la ulceración inducida por etanol en diversos grados, y la dosis alta (150 y 300 mg/kg) de ambos extractos ofreció la mejor conservación (42 % y 50 % de índice de protección contra úlceras, respectivamente) en comparación con los animales no tratados. Los hallazgos histológicos se correlacionaron con los índices de úlcera calculados, y los animales tratados tenían lesiones de la mucosa gástrica menos graves. En extractos de M. balsamina puede poseer actividades antiulcerosas razonables en ratas contra la úlcera gástrica inducida por etanol.

The use of medicinal plants for the treatment of psoriasis: A systematic review and meta-analysis

Background: Psoriasis is a chronic inflammatory disease that presents as scaly patches on the skin that affects about 3% of the world's population. Adherence to treatment and discrimination against people are common problems, adversely impacts quality of life. Objectives: The aim of this study was to investigate the use of medicinal plants as therapeutic adjuvants in the treatment of plaque psoriasis through a systematic review and meta-analysis. Methods: A systematic review and meta-analysis of randomized controlled trials in patients with plaque psoriasis was carried out, comparing the efficacy of herbal treatments alone or in association with other therapies. The search was performed in the databases of The Cochrane Library, Lilacs, Medline via PubMed and Embase, only including studies published from 2016 to 2020.The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework. A systematic review and meta-analysis of randomized controlled trials (RCT) in patients with plaque psoriasis was carried out, comparing the efficacy of herbal treatments alone or in association with other therapies. We comprehensively searched the MEDLINE, Embase, Lilacs and Cochrane Library databases, only including studies published from 2016 to 2020. The certainty of evidence was assessed using the GRADE approach. Results: Out of 2,268 articles evaluated, only seven RCT were eligible for final analysis. Five of these studies evidenced low risk of bias and a high level of evidence. Limitations: Few RCT of medicinal plants. Conclusion: This meta-analysis indicates that medicinal plants may be used as topical or oral products, either alone or combined with other forms of treatment. These products have the potential to greatly improve the quality of life of the patient

Efecto de Tropaeolum Tuberosum o "Mashua" (tropaeolaceae) sobre la expresión génica relacionada a espermatogénesis en ratón

Introducción: Tropaeolum tuberosum, conocido comomashua, es un tubérculo andino que tiene un valor tanto económico como nutritivo para las poblaciones de pocos recursos. Se cree que afecta la fertilidad masculina, porque los hombres andinos lo relacionan con impotencia y disminución de la capacidad fecundante. Estudios hechos en ratas que se alimentaron con mashua demostraron que hubo un 45% de decrecimiento de la tasa testosterona/dihidrotestosterona. El efecto de esta planta en la reproducción está relacionada a su contenido de isotiocianatos, compuestos que se unen covalentemente a las proteínas, las cuales pueden estar directa o indirectamente involucradas en el proceso espermatogénico. El propósito de esta investigación fue evaluar el efecto del extracto acuoso de la mashua sobre la espermatogénesis y la fisiología reproductiva de ratones. Métodos: Se evaluaron los parámetros morfofuncionales in vivo de espermios de ratones (espermatograma) y se cuantificó la expresión de: Cytochrome P450 17α-hydroxylase/17,20-lyase, proteína reguladora de esteroidogénesis aguda, ciclina y protamina, relacionados a la espermatogénesis. Resultados: A los 7, 14 y 21 días de dosificación, se vio afectado el conteo de espermatozoides, así como su motilidad progresiva (MP); por otra parte, se observó un retardo en la maduración de los mismos. En cuanto a la expresión génica, no se encontró diferencias significativas entre la expresión de los dos genes estudiados (cytochrome P450 17α-hydroxylase/17,20-lyase, ciclina). Conclusión: El efecto de la mashua no se da a nivel de la expresión de los genes involucrados en la espermatogénesis, sino a nivel de sus funciones como proteína.

Introduction: Tropaeolum tuberosum, known as "mashua" is an Andean tuber that holds both economic and nutritional value for low-income populations. It is believed that it affects male fertility because Andean men associate it with impotence and decreased fertility. Studies conducted on rats fed with "mashua" showed that there was a 45% decrease in the testosterone/dihydrotestosterone ratio. The effect of this plant on reproduction is related to its content of isothiocyanates, compounds that covalently bind to proteins, which may be directly or indirectly involved in the spermatogenic process. The purpose of this research was to evaluate the effect of the aqueous extract of "mashua" on spermatogenesis and reproductive physiology of mice. Methods: In vivo morphofunctional parameters of mouse sperm (spermatogram) were evaluated and the expression of Cytochrome P450 17α-hydroxylase/17,20-lyase, acute steroidogenesis regulatory protein, cyclin, and protamine related to spermatogenesis was quantified. Results: The results indicated that at 7, 14 and 21 days of dosing, the sperm count was affected, as well as their progressive motility (PM), on the other hand, a delay in their maturation was observed. Regarding gene expression, no significant differences were found between the expression of the two genes studied (Cytochrome P450 17α-hydroxylase/17,20-lyase, Cyclin). Conclusion: The effect of "mashua" does not occur at the level of gene expression involved in spermatogenesis, but at the level of its functions as a protein.

Se evaluó la capacidad antioxidante del extracto hidroetanólico de sanky (EHES) mediante la capacidad de reducir el 2,2-difenil-1-picrilhidracilo (DPPH) y la capacidad de reducir el ion férrico (FRAP). Se utilizaron 30 ratas adultas inducidas a diabetes con dos dosis de aloxano (80mg/kg), formándose cinco grupos (n=6), recibiendo los tratamientos vía orogástrica durante ocho días, el grupo I (agua), II (metformina 14mg/kg), grupos III-IV-V zumo de sanky a 1,0; 4,0 y 16 mL/kg, respectivamente. La glicemia fue evaluada por el método rápido (glucómetro) (primer y octavo día). Terminado el tratamiento los animales fueron sacrificados y se les extrajo el páncreas, para su estudio histopatológico. Resultados. La capacidad antioxidante del EHES mediante el DPPH, mostró un IC50 de 0,77 mg/mL, y por el método FRAP se observó el TEAC-FRAP de 22,31µg/mg. La glicemia disminuyó en el octavo día de tratamiento, respecto al primer día; también se observó disminución de la glicemia en los grupos III-V, respecto al grupo I. A nivel histológico los grupos I-II presentaron atrofia severa y necrosis moderada de los islotes de Langerhans; los grupos IV-V presentaron hipertrofia y necrosis leve multifocal a nivel del islote. Conclusiones. El extracto de sanky presenta capacidad antioxidante in vitro y el zumo ejerce un efecto hipoglicemiante y protector en páncreas.

Objective. To determine the in vitro antioxidant capacity of Corryocactus brevistylus and its effect on glycemia and the pancreas of alloxan-induced diabetic rats. Materials and methods. The antioxidant capacity of the hydroethanolic extract of sanky (HEES) was evaluated by assessing its ability to reduce 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric ion (FRAP). We used thirty adult rats, which were induced to diabetes with two doses of alloxan (80mg/kg). Rats were distributed into 5 groups (n=6), all groups received treatment by orogastric route for eight days. Group I received water, group II received metformin 14mg/kg and groups III, IV and V received sanky juice at 1.0; 4.0 and 16 mL/kg, respectively. Glycemia was evaluated by the rapid method (glucometer) (first and eighth day). After treatment, the animals were sacrificed and the pancreas was removed for histopathological study. Results. The antioxidant capacity of HEES by DPPH showed an IC50 of 0.77 mg/mL; the FRAP method showed a TEAC-FRAP of 22.31µg/mg. Glycemia decreased on the eighth day of treatment, with respect to the first day; a decrease in glycemia was also found in groups III-V, when compared to group I. Histologically, groups I-II presented severe atrophy and moderate necrosis of the islets of Langerhans; groups IV-V presented hypertrophy and mild multifocal necrosis at the islet level. Conclusions. The extract of sanky showed antioxidant capacity in vitro and the juice exerts a hypoglycemic and protective effect on the pancreas.

Phytochemical, Antioxidant and Anti-diabetic Potentials of the Ethanol Leave Extracts of four Medicinal Plants

For many years, medicinal plants have been a resource for healing in several local communities around the world and the phytochemicals in them such as flavonoids, alkaloids, phenolic, tannins, and terpenoids are attributed to their many medicinal values. Vernonia amydalina, Senna alata, Jatropha curcas, and Grewia pubescens are important plants with immense value. In this study, phytochemical screening, antioxidant analysis and the potential anti-hyperglycemic properties of the plants was investigated in-vitro. The ethanol leave extracts of the plants were subjected to qualitative phytochemical screening and tannin, flavonoids and phenol quantification. Ferric reducing antioxidant power and DPPH radical inhibition of the extracts was done by spectrophotometric method while the anti-diabetic potential was analyzed through the in-vitro ?-amylase and ?-glucosidase inhibition. Phytochemicals detected in the ethanol leave extracts of the four plants are tannins, flavonoids, phenolics, terpenoids, steroids, alkaloids, cardiac glycosides, and saponins. Flavonoids, phenols, and tannin content were highest in Senna alata (0.27±0.0.002 mg: mg of rutin per g of extract, 10.63±0.0.017 mg: mg of gallic acid per g of extract, and 6.72±0.06 mg/g respectively) followed by V. amygdalina (0.20±00.002 mg: mg of rutin per g of extract, 8.27±0.0.017 mg: mg of gallic acid per g of extract, and 7.98±0.03 mg/g respectively). While the least content of all was found in the extracts of Jatropha curcas. Concentration dependent and statistically significant difference was observed in both the FRAP and DPPH radical inhibition of all the extracts. Senna alata showed the strongest reducing power followed by the V. amygdalina. Both Senna alata and V. amygdalina showed DPPH radical inhibition that is not significantly (p>0.05) different from that of trolox. ?-amylase and ?-glucosidase inhibition was also demonstrated in a concentration dependent manner. In both the ?-amylase and ?-glucosidase inhibition, V. amygdalina and S. alata exhibited the most significant inhibitory properties among the plant extracts. The overall result in this study suggested that V. amygdalina, S. alata with the highest content of the phytochemicals, and antioxidant activities are potential source of antioxidant constituents and might be useful for the management of diseases such as diabetes.

Abstract Objetive: To determinate the prevalence of fasting hyperglycemia and the use of drugs and medicinal plants in patients trated at the HECA LAB clinical analysis laboratory in Ciudad Ixtepec, Oaxaca. Materials and Methods: A descriptive, cross-sectional study was carried out during the fourth quarter of 2021. A non-probabilistic sampling was carried out, for convenience, incluiding a total of 205 patients. Data collection was carried out by applying a structured questionnaire containing sociodemographic information such as age and sex. Patients with hyperglycemia were questioned about the consumption of medicines and medicinal plants. Glucose levels were determined using the Mindray semi-automatic clinical chemistry analyzer, model BA-88A. A glucose value greater than or equal to 126 mg/dl according to the WHO criteria was considered diabetic. Prevalence was calculated by formula, according to Aschengrau & Seage. Results: Of the 205 patients, 29% had diabetes. 8% were classified as prediabetic with a predominance of females. The most frequent age range was 54-65 years with 32%. 82% reported taking pharmacological treatment and 63% of those surveyed reported consuming medicinal plantas for the treatment of diabetes. Conclusions: The prevalence of diabetes in the studied patients was 29%. Oral monotherapy with metformin was the most frequent treatment, followed by the use of subcutaneous insulin. Eleven medicinal plants were referred, being moringa (Moringa oleifera), the most used. 18% did not receive pharmacological treatment. For this reason, it is necessary to establish timely health education interventions on lifestyle changes and adherence to pharmacological treatment of patients with diabetes mellitus; to achieve adequate management of the disease and avoid complications.

Perfil do uso de medicamentos sintéticos e fitoterápicos por gestantes atendidas em uma Unidade Básica de Saúde localizada na região norte do Ceará / Profile of synthetic drugs and herbal medicines used by pregnant women seen in basic health unit in northern Ceará State, Brazil / Perfil de utilización de medicamentos sintéticos y fitoterápicos por mujeres embarazadas atendidas en Unidad Básica de Salud ubicada en la región norte de Ceará

Introdução: Há escassez de dados clínicos sobre os medicamentos em pacientes gestantes. Para auxiliar na conduta da farmacoterapia nessas pacientes, a Food and Drug Administration (FDA) criou, em 1979, normas de classificação de risco gestacional para os medicamentos. Além disso, no Brasil, há o uso de fitoterapia pela população, atrelada a fatores socioculturais e econômicos, por vezes sem que se saiba quais os riscos que as plantas medicinais possam trazer aos pacientes, sobretudo em gestantes. Objetivo: Descrever o uso de medicamentos sintéticos e fitoterápicos por gestantes atendidas em uma Unidade Básica de Saúde, relatando o perfil socioeconômico e histórico de paridade das entrevistadas e classificando o risco gestacional dos insumos utilizados. Métodos: Trata-se de uma pesquisa exploratória, descritiva, com abordagem qualitativa, em uma Unidade Básica de Saúde localizada no interior do Ceará. Foram incluídas no estudo as gestantes que realizavam acompanhamento pré-natal na unidade, em qualquer trimestre gestacional, sendo excluídas aquelas menores de idade. Os dados foram coletados por meio de um formulário estruturado, após as participantes assinarem o Termo de Consentimento Livre e Esclarecido. Os dados foram tabulados utilizando o Microsoft Excel 365. A classificação de risco dos medicamentos foi realizada utilizando os critérios do FDA, e as plantas medicinais foram classificadas de acordo com os resultados obtidos na literatura em "Indicadas", "Indicadas com ressalvas" ou "Contraindicadas". Estudo aprovado pelo Comitê de Ética em Pesquisa, com número do parecer 3.569.328. Resultados: Participaram um total de 43 gestantes, das quais 15 (34,88%) apresentaram algum tipo de comorbidade, sendo diabetes gestacional, rinite alérgica e hipertensão as mais prevalentes. 41 participantes (95,35%) utilizaram algum medicamento durante a gestação, com destaque de medicamentos de risco B e C (84,44% do total). Em relação ao uso de fitoterapia, 13 gestantes (30,23%) fizeram uso de alguma planta medicinal, onde somente uma das espécies utilizadas apresentou ser indicada com ressalvas durante a gestação. Conclusões: Observou-se que um dos fatores associados com o uso de medicamentos na gestação é o início do pré-natal. Apesar de as gestantes evitarem o uso de medicamentos sintéticos sem indicação, o mesmo não ocorre em relação ao uso fitoterapia, que é realizado de forma indiscriminada. Ademais, ressalta-se a falta de estudos dos riscos de medicamentos durante o período gestacional e a falta do farmacêutico no acompanhamento pré-natal, profissional capaz de promover Uso Racional de Medicamentos, podendo melhorar o perfil de uso de medicamentos por essas pacientes.

Introduction: There is a shortage of clinical data on drugs in pregnant patients. To assist in the management of pharmacotherapy in these patients, the Food and Drug Administration (FDA) created, in 1979, rules for classification of pregnancy risk for drugs. In addition, in Brazil, there is use of phytotherapics by the population, linked to socio-cultural and economical factors, at times without knowing what risks medicinal plants can bring to patients, especially in pregnant women. Objective: To describe the use of synthetic drugs and herbal medicines by pregnant women seen at a Basic Health Unit, reporting the socioeconomic profile and historical parity of the interviewees and classifying the gestational risk of the medicines used. Methods: This is an exploratory, descriptive research, with a qualitative approach, in a Basic Health Unit located in a provincial city of Ceará. Pregnant women who underwent prenatal care at the unit in any gestational trimester were included in the study, and those underage were excluded. Data was collected using a structured form, after the participants signed the Free and Informed Consent Form and charted using Microsoft Excel 365. The risk classification of drugs was carried out using the FDA criteria and medicinal plants were classified according to the results obtained in the literature under "Indicated", "Indicated with reservations" or "Admonished". Study approved by the Research Ethics Committee, under the file 3,569,328. Results: A total of 43 pregnant women participated, of which 15 (34.88%) had some type of comorbidity, with gestational diabetes, allergic rhinitis and hypertension being the most prevalent. 41 participants (95.35%) used some medication during pregnancy, with emphasis on medications with risks on B and C (84.44% of the total). Regarding the use of phytotherapy, 13 pregnant women (30.23%) used some medicinal plant, where only one of the species described was Indicated with reservations during pregnancy. Conclusions: It was observed that one of the factors associated with use of medications during pregnancy is the beginning of prenatal care. Although pregnant women avoid the use of synthetic medicines without indication, the same does not happen on the use of phytotherapy, which is carried out indiscriminately. In addition, the lack of studies on the risks of medications during pregnancy and the absence of pharmacists in prenatal care, a professional capable of promoting rational use of medications who could improve the profile of medication used by these patients.

Introducción: Los datos clínicos sobre medicamentos en mujeres embarazadas son escasos. Para ayudar en la realización de la farmacoterapia en estos pacientes, la Administración de Alimentos y Medicamentos (FDA) creó, en 1979, reglas para la clasificación del riesgo gestacional de los medicamentos. Además, en Brasil, la fitoterapia es utilizada por la población, vinculada a factores socioculturales y económicos, a veces sin conocer los riesgos que las plantas medicinales pueden traer a los pacientes, especialmente a las mujeres embarazadas. Objetivo: Describir el uso de medicamentos sintéticos y herbales por gestantes atendidas en una Unidad Básica de Salud, reportando el perfil socioeconómico y paridad histórica de las entrevistadas y clasificando el riesgo gestacional de los insumos utilizados. Métodos: Se trata de una investigación exploratoria, descriptiva, con enfoque cualitativo, en una Unidad Básica de Salud ubicada en el interior de Ceará. Se incluyeron en el estudio las mujeres embarazadas que se sometieron a atención prenatal en la unidad en cualquier trimestre de gestación y se excluyeron las menores de edad. Los datos fueron recolectados a través de un formulario estructurado, luego de que los participantes firmaran el Formulario de Consentimiento Libre e Informado. Los datos se tabularon mediante Microsoft Excel 365. La clasificación de riesgo de los fármacos se realizó según los criterios de la FDA y las plantas medicinales se clasificaron según los resultados obtenidos en la literatura en "Indicados", "Indicados con reservas" o "Contraindicados". Estudio aprobado por el Comité de Ética en Investigación, con dictamen número 3.569.328. Resultados: Participaron un total de 43 gestantes, de las cuales 15 (34,88%) presentaban algún tipo de comorbilidad, siendo la diabetes gestacional, rinitis alérgica e hipertensión las más prevalentes. 41 participantes (95,35%) utilizaron algún medicamento durante el embarazo, destinado a medicamentos de riesgo B y C (84,44% del total). En cuanto al uso de fitoterapia, 13 gestantes (30,23%) utilizaron alguna planta medicinal, donde solo una de las especies utilizadas se indicó con reservas durante la gestación. Conclusiones: Se observó que uno de los factores asociados al uso de medicamentos durante el embarazo es el inicio de la atención prenatal. Si bien las mujeres embarazadas evitan el uso de medicamentos sintéticos sin indicación, no ocurre lo mismo con relación al uso de fitoterápicos, que se realiza de forma indiscriminada. Además, la falta de estudios sobre los riesgos de los medicamentos durante el embarazo y la falta de farmacéuticos en la atención prenatal, un profesional capaz de promover el Uso Racional de los Medicamentos, puede mejorar el perfil de uso de medicamentos por parte de estas pacientes.

Ethnobotanical Survey, Physiochemical Composition and Preliminary Cytotoxic Evaluation of some Medicinal Plants with Anticancer Potential from Certain Areas in South-West Nigeria

Aims: Medicinal plants used by traditional medical practitioners (TMP) to treat cancers are considered safe when used alone or combined with conventional therapy to ensure their effectiveness and eliminate the toxic effects of orthodox medicines. Using cytotoxic and antioxidant studies, the study attempted to assess some of the commonly used medicinal plants used to cure cancer among Yoruba people in Ogun, Oyo, Osun, and Lagos (South-West, Nigeria). Study Design: Samples of commonly utilized anticancer plants obtained from the chosen areas using physical and virtual oral seminars were studied for physiochemical composition and a possible antioxidant and cytotoxic potential to validate the basis for the use of the selected anticancer plants. Methodology: Online academic literature searches were done on the cited plants to identify the already-exploited anticancer plants. The ethanolic extracts of the plant were examined for the presence of bioactive components and their total flavonoid content, with focusing on quercetin detection using thin layer bioautography (TLB) and brine shrimp lethality assay (BSLA) for cytotoxicity. In comparison to quercetin and ascorbic acid, the scavenging of superoxide radical (SOR), hydrogen peroxide, and 2, 2-Diphenyl-2-picrylhydrazyl (DPPH) radical activity by a model (most biologically active) of the anticancer plant was also evaluated. Results: There were only twelve anticancer species that were not used in related studies: Lannea egregia, Ficus exasperate, Croton zambesicus, Tetrapleurai tetraptera, Terminalia catappa, Zanthoxylum zanthoxyloides, Plumbago zelanica, Hilleria latifolia, Bryophyllum pinntum, Chromolena odorata, Brysocarpus coccineus and Spondias mombin. The anticancer plants contained bioactive and mineral substances like saponins, protein, lipids, magnesium, calcium, iron, zinc, and a decreased Na/K concentration. The plants had a fair amount of flavonoids and variable levels of cytotoxicity. L. egeregia was regarded as the prototype of the anticancer species due to its profound flavonoid concentration (85.40 µg/mL) and cytotoxicity (9.46 µg/mL) compared to other extracts. The TLB also demonstrated the presence of quercetin, with a dose-dependent antioxidant property. The anticancer model's overall antioxidant activity (34.72 µg/mL) was slightly lower than quercetin (30.44 µg/mL) but higher than ascorbic acid (41.68 µg/mL). Conclusion: The results support the traditional use of anticancer species as nutritional and dietary supplements, whose bioactive compounds are relevant in managing cancer patients. The plant’s bioactive principles need to be characterized in future research.

Commentators View on Medicinal Plants of Sushrutokta Salsaradi Gana Regarding their Controversial Botanical Identity: A Review

A família Asteraceae foi observada como a família dominante entre todas as famílias com 10 espécies, a folha foi a parte mais utilizada e a decocção 36% foi o tipo de preparação mais preferido. A erva foi a forma de vida predominante (67%). O UV máximo (0,92) foi demonstrado pelas espécies de J. adhatoda L., enquanto A. sativum L. mostra RFC máximo (0,58), o maior valor de ICF representado por diarreia e dermatite 0,92, e alto valor de FL é registrado 100%. De acordo com nossas coleções, as espécies selvagens foram 45%, as espécies invasoras 38% e as cultivadas 17% registradas, as espécies dicotiledôneas foram registradas mais 81%. Sete espécies medicinais estão sendo economicamente importantes e exportadas para o mercado local e internacional do mundo, enquanto as espécies de P. integrima L. foram as espécies mais exportadas de acordo com os comerciantes locais. A área investigada é rural e a população local depende das plantas da área para suas necessidades de saúde e outros usos como vegetal, lenha, forragem etc. O resultado atual de RFC, UV, ICF, FL e JI mostra que a flora medicinal precisa ser investigada farmacológica e fitoquimicamente para comprovar sua eficácia. A documentação do conhecimento medicinal é importante para preservar esse precioso conhecimento antigo antes que se perca para sempre, devido às mudanças tecnológicas e ambientais do mundo.

Analysis and comparison of major plant databases in China and ASEAN countries / 国际中医中药杂志

At present, countries around the world are paying greater attention to the protection of medicinal plants and traditional medicinal knowledge resources, and are looking for various ways to protect medicinal plants. Many countries have established their own databases to save the medicinal plant information resources. This paper focuses on the introduction of medicinal plant databases in six countries including Malaysia, Philippines, and Singapore, and compares their basic information. It is difficult to achieve integration and sharing among these databases. It brings certain difficulties to the use of researchers in related fields. It is suggested that the construction of a multinational common medicinal plant database should be included in the "Belt and Road Initiative" to systematically organize massive information, enhance exchanges between countries on traditional medicinal plants, and achieve medicinal plant information sharing, and the establishment of a shared database will reduce optimization and maintenance to a certain extent or renewal work, laying the foundation for the protection, development and sustainable use of traditional medicinal plant resources.
