Medicinal plants and their importance for the conservation of biocultural knowledge in primary school students of the Paniquita Indigenous Community (Rivera, Huila, Colombia) / Plantas medicinales y su importancia para la conservación del conocimiento biocultural en estudiantes de primaria de la Comunidad Indígena Paniquita (Rivera, Huila, Colombia)

Ethnobotany approached through ethnoeducation allows for the preservation of the cultural heritage of indigenous communities. In this way, the ethnobotanical knowledge of primary school students from the Paniquita Indigenous Community was recognized, regarding the cultural knowledge of medicinal plants and their significance in the conservation of the biocultural heritage. This research had a qualitative, ethnographic approach. The sample consisted of ten students who were part of a focus group, ethnobotanical walks, and participatory workshops with drawings since they stimulate students' creative and dynamic thinking and strengthen interculturality. Twenty-one plants were reported, which are used to relieve sore throats, headaches, and stomach aches, as well as to treat diarrhea and fever, to prevent flu, and as a purgative. All the medicinal plants mentioned grow in the community and are either cultivated or wild, which also shows the students' knowledge of the ir territory. These findings reflect the importance of ethno-education and ethnobotany at school and how historical reconstruction processes are generated from these settings, where indigenous ancestral knowledge is made visible.

La etnobotánica abordada desde la etnoeducación permite mantener el legado cultural de los pueblos originarios. De esta manera, se reconoció el conocimiento etnobotáni co de los estudiantes de primaria de la Comunidad Indígena Paniquita, sobre el conocimiento cultural de las plantas medicinales y su importancia para la conservación del patrimonio biocultural. La investigación tuvo un enfoque cualitativo y etnográfico. La muestra estuvo conformada por diez estudiantes que formaron parte de un grupo focal, caminatas etnobotánicas y talleres participativos con dibujos, ya que estimulan el pensamiento creativo y dinámico de los estudiantes y fortalecen la interculturalidad. Se reportaron 21 plantas que se utilizan para aliviar dolores de garganta, cabeza y estómago, así como para tratar la diarrea y la fiebre, para prevenir la gripe y como purgante. Todas las plantas medicinales mencionadas crecen en la comunidad y son cultivadas o silvestres, lo que también demuestra el conocimiento que los estudiantes tienen de su territorio. Estos hallazgos reflejan la importancia de la etnoeducación y la etnobotánica en la escuela y cómo se generan procesos de reconstrucción histórica desde estos escenarios, donde se visibiliza el conocimiento ancestral indígena.

Ethnobotanical Survey and Agro-Morphological Characterization of Ginger (Zingiber officinale Rosc., Zingiberaceae) Cultivars in South Benin

Ginger (Zingiber officinale Rosc., Zingiberaceae), a cultivated annual herbaceous plant is one of the most important spices consumed in the world with many medicinal properties. It is an income-generating plant for its production. This study aims to document endogenous knowledge on speculation as well as an agro-morphological characterization in order to make it better known and to reveal its potential to the whole world. The ethnobotanical data obtained by a semi-structured survey conducted from a questionnaire in six (06) municipalities in southern Benin made it possible to determine the local taxonomy of Ginger, the cultural practices and the different uses of the species. Ginger has been introduced in Benin for decades and in all the area study. The local names for the species as well as its uses, vary according to locality. As for the agro-morphological characterization, a complete random block device composed of five sub-plots was used. The experimental data allowed us to obtain three classes with all the accessions collected. Ginger cultivation is widespread in the study area with production on a small area. The cultivation techniques adopted do not follow any defined technical itinerary and the production tools are often rudimentary. The cultivation of ginger is therefore limited despite its multiple medicinal and economic potential. The institutions in charge of agriculture do not have data concerning the cultivation of ginger in southern Benin.

Preliminary Pharmacognostic and Phytochemical Screening of Leaves of Cosmostigma racemosum (roxb.) Wight.

Pharmacognostic and phytochemical evaluation are necessary for drug authentication and for prediction and confirmation of pharmacological activities of any plant part. Cosmostigma racemosum (Roxb.) Wight, a traditional and folklore drug in Kerala with many reputed usages, locally called as Vaattuvalli, is a shrubby twiner of Apocynaceae family. Leaves are the most used plant part. As no scientific data regarding its standards were available, preliminary pharmacognostic, physico-chemical and phytochemical evaluation of the leaves were done as per the guidelines of Ayurveda Pharmacopoiea of India and WHO. The study revealed that leaves of Cosmostigma racemosum (Roxb.)Wight are simple, opposite, exstipulate, apex caudate, base cordate and with a characteristic chilly odour. Microscopic examination of leaves revealed the presence of characteristic features such as lacticifers, secreting cells, absence of stomata on the upper epidermis, presence of paracytic stomata on the lower epidermis and presence of calcium oxalate crystals especially druse crystals. The preliminary phytochemical evaluation revealed the presence of tannins, alkaloids, steroids, saponins which indicates the wide range of pharmacological activities of the plant. The 13 peaks in the HPTLC profile indicate a wide pharmacological prospect of the leaves. The ICP-MS analysis confirmed that heavy metals like Cd, Cr, Zn, Cu, Pb and As present in the leaves are within permissible limits. Physicochemical parameters such as moisture content, different ash values, volatile oil content, different extractive values, ph, fibre content, and sugar content were also determined. All these findings can serve as standards for assuring the safety, quality and purity of the drug.

De esta manera, la presente investigación tuvo como objetivo reconocer la flora útil, las categorías etnobotánicas y de estimar si existe una diferencia entre las especies utilizadas, según su origen (silvestre o cultivado), en estudiantes de Grado 5° de la Escuela Rural Mixta El Colorado, del Resguardo Indígena de Cohetando, municipio de Páez, Cauca. El proceso metodológico se realizó bajo un enfoque mixto; lo cualitativo, desde el método etnográfico, haciendo uso de técnicas, como la observación participante, recorridos etnobotánicos y entrevista semiestructuradas; lo cuantitativo, se llevó a cabo a partir de un análisis multivariado, utilizando el índice de Jaccard, para estimar la similitud entre las categorías etnobotánicas; asimismo, se realizó un análisis de varianza (ANOVA), para estimar si existe diferencias significativas entre el origen de las especies. A partir de lo anterior, los estudiantes reportaron 81 especies de plantas útiles, agrupadas en seis categorías etnobotánicas, siendo ornamentación y medicinal y alimenticia, las más relevantes, por número de especies. En cuanto al origen, se encontró una diferencia significativa, en cuanto al mayor número de usos para las especies cultivadas, respecto a las silvestres. Finalmente, se evidencia el alto grado de conocimiento que tienen los estudiantes sobre la flora, así como la importancia para su Resguardo Indígena, como un símbolo de resistencia, que permite salvaguardar la memoria histórica.

ABSTRACT One of the most complex challenges faced in the school is the articulation of cultural knowledge with school curricula. Thus, this research aimed to recognize the useful flora, the ethnobotanical categories, and to estimate if there is a difference between species according to their origin (wild and/or cultivated) according to the knowledge constructed by the 5th grade students of the Mixed Rural School El Colorado, of the Indigenous Resguardo of Cohetando, municipality of Páez, Cauca. The methodological process was carried out under a mixed approach, the qualitative from the ethnographic method, making use of techniques such as participant observation, ethnobotanical tours and semi-structured interviews. The quantitative part was carried out from a multivariate analysis, using Jaccard's index to estimate the similarity between the ethnobotanical categories; likewise, an analysis of variance (ANOVA) was performed to estimate if there are significant differences between the origin of the species and the origin of the species. From the above, students reported 81 useful plants grouped into six ethnobotanical categories, being ornamentation, and medicinal and food the most relevant by number of species. In terms of origin, a significant difference was found for the cultivated category with respect to the wild category. Finally, the high degree of knowledge that the students have about the useful flora is evident, as well as the importance for their Indigenous Reservation as a symbol of resistance that allows safeguarding the historical memory.

Plantas medicinais na Atenção Primária à Saúde: riscos, toxicidade e potencial para interação medicamentosa / Medicinal plants in primary health care: risks, toxicity and potential for drug interaction

Visando contribuir para o fortalecimento do uso adequado de fitoterápicos na Atenção Primária à Saúde (APS), este estudo apresenta resultados de pesquisa exploratório-descritiva que buscou avaliar o risco associado ao uso de plantas medicinais. Foi realizado um levantamento etnobotânico e etnofarmacológico junto à população da área de abrangência de uma Unidade de Saúde da Família (USF) rural localizada em um município da região Sul do Brasil. Em 80,65% dos domicílios visitados, verificou-se que o uso terapêutico de plantas medicinais estava associado a medicamentos de uso contínuo, e 51,61% dos entrevistados relataram não comunicar o uso de plantas medicinais ao profissional de saúde. 58,33% das espécies identificadas apresentaram possíveis riscos, contraindicações ou toxicidade, e 35,83% apresentaram possíveis interações com medicamentos convencionais de acordo com a literatura consultada. Discute-se sobre os riscos associados ao uso dessas plantas nessa população, e apresentam-se sugestões e orientações para minimizar esses riscos.

To contribute to the strengthening of the appropriate use of herbal medicines in primary health care, this study presents the results of exploratory and descriptive research which sought to assess the risk associated with the use of medicinal plants. It was realized an ethnobotanical and ethnopharmacological survey, carried out with the population of the areacovered by a rural Family Health Care Unit located in a county in the South region of Brazil. In 80.65% of the households visited, it was found that the therapeutic use of medicinal plants was associated with continuous-use medications, and 51.61% of the interviewees reported not communicating the use of medicinal plants to the health professional. 58.33% of the identified species presented possible risks, contraindications, or toxicity, and 35.83% presented possible interactions with conventional drugs according to the literature consulted. It discusses the risks associated with the use of these plants in this population and offers suggestions and guidelines to minimize these risks.

Actividad antioxidante y cuantificación de fenoles y flavonoides de plantas colombianas empleadas en infecciones urinarias / Antioxidant activity and quantification of phenols and flavonoids of Colombian plants used in urinary tract infections

RESUMEN Las plantas medicinales son de interés farmacéutico, debido a que tienen diferentes propiedades biológicas, entre las que se destaca, la actividad antioxidante y, de la cual, se conoce que existe una relación con la concentración de los compuestos fenólicos, por su capacidad de reducir los radicales libres. Es así, que se propuso evaluar la actividad antioxidante y la cuantificación de fenoles y flavonoides totales, de 11 extractos etanólicos de plantas, empleadas en la medicina tradicional, para el tratamiento de infecciones urinarias (IU). Se evaluó la actividad antioxidante, por los métodos de DPPH y FRAP y se cuantificó el contenido fenólico y de flavonoides, por el método Folin-Ciocalteu y tricloruro de aluminio, respectivamente. Se encontró que, de los 11 extractos evaluados, los que presentaron el mayor contenido de estos metabolitos y de potencial antioxidante fueron: Uncaria tomentosa, Sedum praealtum y Kohleria hirsuta. Este trabajo permitió contribuir al conocimiento fitoquímico y antioxidante de plantas, usadas para tratar IU y se sugiere que U. tomentosa, S. praealtum y K. hirsuta sean objeto de futuros estudios biodirigidos, así como la evaluación de otras actividades biológicas.

ABSTRACT Medicinal plants are of pharmaceutical interest because they possess different biological properties, among which their antioxidant activity stands out, and therefore it is known that there is a relationship with the concentration of phenolic compounds due to their ability to reduce free radicals. Therefore, it was proposed to evaluate the antioxidant activity and the quantification of phenols and flavonoids of 11 ethanolic extracts of plants used in traditional medicine for the treatment of urinary infections (UI). The antioxidant activity was evaluated by the DPPH and FRAP methods and the phenolic and flavonoid content was quantified by the Folin-Ciocalteu and aluminum trichloride method, respectively. It was found that of the 11 extracts evaluated, those with the highest content of these metabolites and antioxidant potential were three: Uncaria tomentosa, Sedum praealtum and Kohleria hirsuta. This work made it possible to contribute to the phytochemical and antioxidant knowledge of the plants used for the treatment of UI and it is suggested that U. tomentosa, S. praealtum and K. hirsuta be the object of future bio-directed studies, as well as the evaluation of other activities biological.

Review on the Ethnobotany, Phytochemical and Pharmacological Profile of Senna occidentalis L. (Fabaceae): Potential Application as Remedy in the Treatment of Dysmenorrhea

Senna occidentalis L. has been used in several traditional medicines against various diseases and this is based on its botanical, ethnopharmacology, and phytochemistry profiles. This powerful herb is recognized for its antibacterial, antifungal, antidiabetic, anticancer, antimutagenic, protective, and inflammatory hepatic activity. Multiple chemical compounds, including achrosine, aloe-emodin, emodin, anthraquinones, etc., have been isolated from this plant. The results of this bibliographic research thus presented in this review have demonstrated the ability of certain extracts from S. occidentalis L. to lower the lipid peroxide content, the activity of gamma-glutamyl transpeptidase and phospholipase A2 in exudates of the granuloma of cotton pellets, thus resulting in a reduced availability of arachidonic acid, an important precursor in the biosynthesis of prostaglandins, which are the only likely source and/or cause of dysmenorrhea. Thus, based on its phytochemical profile and its pharmacological properties, it is therefore suggested that S. occidentalis would be a potential and effective remedy in the treatment of dysmenorrhea
