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.

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.

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

O objetivo deste trabalho foi realizar um estudo etnobotânico sobre as plantas medicinais utilizadas pelos moradores de um bairro localizado em um município ribeirinho do interior do estado do Amazonas. Participaram do estudo cem indivíduos, e os dados obtidos pela pesquisa foram compilados por meio de um formulário, contendo 14 questões (objetivas e discursivas). Os resultados demonstraram que 95% dos moradores faziam uso de plantas medicinais. Foram citadas 89 espécies, pertencentes a 48 famílias botânicas, com destaque para a Lamiaceae. As plantas mais citadas foram: Plectranthus barbatus (boldo) ­ 6,1%, Citrus sinensis (laranjeira) ­ 5,8% e Allium sativum (alho) ­ 4,7%. No entanto, quando analisado o índice de concordância (porcentagem de uso principal = CUP), a Citrus sinensis (laranjeira) apresentou um CUP de 80,9%, seguida por Plectranthus barbatus (boldo) e Disphania ambrosioides (mastruz), com 68,1% e 61,5%, respectivamente. Com relação ao modo de preparo, 61,1% citaram infusão, e as principais enfermidades tratadas foram as dores de estômago, com 13,1%. É importante enfatizar a necessidade de mais estudos acerca dos reais benefícios dessas ervas, a fim de que a divulgação de tais informações possa complementar o conhecimento empírico já difundido entre a população local. Dessa forma, será possível ampliar o conhecimento etnobotânico como um todo e, consequentemente, promover saúde e bem-estar.

Despite the evolution of scientific knowledge, the use of medicinal plants is one of the oldest practices still used by men and, especially by the inhabitants of communities and municipalities of the interior of Brazil, mainly in regions with low human development rates. The purpose of this work was to perform an ethnobotanical study on medicinal plants used by residents of a neighborhood located in a riverside city in the interior of the state of Amazonas. A total of 100 individuals participated in the study, with data being obtained through the use of a form containing 14 open and closed-ended questions. The results showed that 95% of the residents used medicinal plants. A total of 89 species, belonging to 48 botanical families were mentioned, with emphasis to Lamiaceae. The plants that were most frequently mentioned were Plectranthus barbatus (locally known as boldo) ­ 6.1%; Citrus sinensis (orange tree) ­ 5.8%; and Allium sativum (garlic) ­ 4.7%. However, when analyzing the agreement index (percentage of main use = CUP), Citrus sinensis (orange tree) presented a CUP of 80.9%, followed by Plectranthus barbatus (boldo) and Disphania ambrosioides (Mexican tea), with 68.1 and 61.5%, respectively. In relation to the method of preparation, 61.1% cited infusion, with the main disorder treated being stomachache, with 13.1%. It is important to emphasize the need for further studies on the actual benefits of these herbs so that the dissemination of the information can complement the already widespread empirical knowledge among the local population.

Background: Coronavirus infectious disease 2019 (COVID-19) caused by the infection with the new coronavirus SARS-CoV-2 has affected the life and health of more than 222 million people. In the absence of any specific pharmacological treatment, the need to find new therapeutic alternatives is clear. Medicinal plants are widely used worldwide to treat different conditions, including COVID-19; however, in most cases, there are no specific studies to evaluate the efficacy of these treatments. Objective: This article evaluates the antiviral effect of six plant extracts used by indigenous and afro Colombian people against SARS-CoV-2 in vitro. Methods: The antiviral effect of six extracts prepared from plants used in Colombian traditional medicine was evaluated against SARS-CoV-2 through a pre-post treatment strategy on the Vero E6 cell line. Once cytotoxicity was established through an MTT assay, the antiviral effect of the extracts was calculated based on the reduction in the viral titer determined by plaque assay. Results:Gliricidia sepium inhibited SARS-CoV-2 in a 75.6%, 56.8%, 62.5% and 40.0% at 10 mg/mL, 8 mg/mL, 6 mg/mL, and 2 mg/mL, respectively, while Piper tuberculatumtreatment reduced viral titer in 33.3% at 6 mg/mL after 48h. Conclusion:G. sepium and P. tuberculatum extracts exhibit antiviral activity against SARS-CoV-2 in vitro

Introducción: La enfermedad infecciosa causada por el coronavirus 2019 (COVID-19) generada por la infección con el nuevo coronavirus SARS-CoV-2 ha afectado la vida y la salud de mas de 222 millones de personas. En ausencia de algún tratamiento farmacológico específico, la necesidad de encontrar nuevas alternativas terapéuticas es clara. Las plantas medicinales son utilizadas en todo el mundo para tratar diferentes condiciones, incluyendo el COVID-19; sin embargo, en la mayoría de los casos no existen estudios específicos que evalúen la eficacia de estos tratamientos. Objetivo: En este artículo, evaluamos el efecto antiviral de seis extractos de plantas usadas por pueblos indígenas y afrocolombianos contra el SARS-CoV-2 in vitro.Metodología: El efecto antiviral de seis extractos preparados a partir de plantas usadas en medicina tradicional colombiana fue evaluado contra SARS-CoV-2 por medio de una estrategia de pre-post tratamiento en células Vero E6. Una vez se estableció la citotoxicidad por un ensayo de MTT, el efecto antiviral de estos extractos fue calculado basado en la reducción del título viral determinado por ensayo de plaqueo. Resultados:G. sepium inhibió SARS-CoV-2 en un 75.6%, 56.8%, 62.5% y 40.0% a 10 mg/mL, 8 mg/mL, 6 mg/mL, and 2 mg/mL, respectivamente. Mientras el extracto de Piper tuberculatum redujo el título viral en un 33.3% a 6 mg/mL luego de 48h de tratamiento

An ethno-botanical study of indigenous medicinal plants and their usage in rural valleys of Swabi and Hazara region of Pakistan / Um estudo etnobotânico de plantas medicinais indígenas e seu uso nos vales rurais da região de Swabi e Hazara, no Paquistão

An ethnobotanical study was conducted to document indigenous medicinal plants and their usage from knowledgeable and elderly persons in Razzar and Gadoon valley of Swabi and Allai and Tanawal valley of Hazara region of Pakistan during 2016-2019. Several systematic field visits and questionnaire surveys were carried out in selected sites of the study area to gather relevant information from the local community. Rapid assessment method was adopted for data collection by interviewing the local people having enough knowledge of medicinal plants use for treatment of different ailments. UV (UV) formula was applied to calculate the relative importance of medicinal plant species in each site of the study area. In the present study, 221 medicinal plants belonging to 105 families have been reported through 580 respondents (385 males, 138 females and 57 local health healer) from the Swabi and Hazara region. The main sources of herbal medicines were leaves (21%) followed by fruits (21%), seeds (17%), whole plants (14%), roots (9%), bark (9%), flowers (7%) and gum (2%). Mentha spicata L. and Berberis lycium Royle were reported with highest UV (UV) i.e. 0.92 and 0.68 in Razzar tehsil and Gadoon valley of Swabi, whereas Mentha longifolia L and Geranium wallichianum D were reported with highest UV i.e. (0.65) and (0.88) in Allai and Tanawal valley of Hazara region, respectively. It was concluded that Swabi and Hazara region is rich in medicinal plants species and associated traditional knowledge. Moreover, ethno-medicines have played significant role in the indigenous healthcare system of the study area. However, uprooting the entire plant for ethno-medicine is a big threat to conservation of medicinal plants diversity in the study area.

Um estudo etnobotânico foi realizado para documentar as plantas medicinais indígenas e seu uso por pessoas experientes e idosas em Razzar e Gadoon, no vale de Swabi e no vale Allai e Tanawal da região de Hazara, no Paquistão, durante 2016 a 2019. Várias visitas sistemáticas de campo e pesquisas por questionário foram realizadas em locais selecionados da área de estudo para coletar informações relevantes da comunidade local. O método de avaliação rápida foi adotado para a coleta de dados por meio de entrevistas com a população local, com conhecimento suficiente do uso de plantas medicinais para o tratamento de diferentes enfermidades. A fórmula UV (UV) foi aplicada para calcular a importância relativa das espécies de plantas medicinais em cada local da área de estudo. No presente estudo, 221 plantas medicinais pertencentes a 105 famílias foram relatadas por 580 entrevistados (385 homens, 138 mulheres e 57 curandeiros locais) da região de Swabi e Hazara. As principais fontes de medicamentos fitoterápicos foram folhas (21%), seguidas de frutas (21%), sementes (17%), plantas inteiras (14%), raízes (9%), cascas (9%), flores (7%) e goma (2%). Mentha spicata L. e Berberis lycium Royle foram relatados com maior UV (UV), ou seja, 0,92 e 0,68 em Razzar tehsil e vale Gadoon de Swabi, enquanto Mentha longifolia L. e Geranium wallichianum D. foram relatados com maior UV, isto é, 0,65 e 0,88 no vale Allai e Tanawal da região de Hazara, respectivamente. Concluiu-se que a região de Swabi e Hazara é rica em espécies de plantas medicinais e conhecimentos tradicionais associados. Além disso, etnomedicamentos têm desempenhado um papel significativo no sistema de saúde indígena da área de estudo. No entanto, arrancar a planta inteira para etnomedicina é uma grande ameaça à conservação da diversidade de plantas medicinais na área de estudo.

Uso tradicional de plantas medicinales en adultos mayores del municipio de Arauca / Traditional use of medicinal plants in older adults in the municipality of Arauca

Introducción: La pérdida del conocimiento tradicional, trae consigo, entre otros, detrimento de identidad cultural y disminución de la biodiversidad. Objetivos: Identificar los conocimientos tradicionales sobre plantas medicinales con base en los saberes de los adultos mayores del municipio de Arauca. Materiales y métodos: Se aplicó una encuesta adaptada de TRAMIL, en una muestra por conveniencia, de 96 adultos mayores sabedores. Con los datos, se determinó el Índice de Valor de Uso (IVU) y el Nivel de Uso Significativo TRAMIL (UST) de las plantas medicinales que, tradicionalmente emplea esta comunidad. Resultados: Se reconocieron 109 especies con uso medicinal, de las cuales 38 (35%) se encuentran aprobadas por el INVIMA; de ellas, presentaron mayor IVU dentro de la comunidad araucana, sábila (Aloe vera) (27%), hierba buena (Mentha spicata) (14%), limón mandarino (Citrus limonia) (13%) y, manzanilla (Matricaria chamomilla) (11%). Las especies con mayor UST, correspondieron a sábila (A. vera), 50%, pericón (Capraria biflora) (45%), limonaria (Cymbopogon citratus) (28%), hierba buena (M. spicata) (27%) y hierba mora (Solanum americanum) (22%). Discusión: Si bien el adulto mayor de Arauca presenta conocimientos importantes sobre el empleo de plantas medicinales que contribuyen a mejorar la calidad de salud en la comunidad araucana, se hace necesario la validación farmacológica, fitoquímica y toxicológica de las especies vegetales utilizadas, debido a que la mayoría no están aprobadas por el INVIMA y en las aprobadas, su forma de empleo no coincide apropiadamente con el aval del instituto de vigilancia.

Introduction: The loss of traditional knowledge brings with it, among other things, a loss of cultural identity and a decrease in biodiversity. Objectives: To identify traditional knowledge about medicinal plants based on the knowledge of older adults in the municipality of Arauca. Materials and methods: A survey adapted from TRAMIL was applied to a convenience sample of 96 knowledgeable older adults. With the data, the Use Value Index (IVU) and the TRAMIL Significant Use Level (UST) of the medicinal plants traditionally used by this community were determined. Results: A total of 109 species with medicinal use were recognized, of which 38 (35%) are approved by the INVIMA; of these, the following had the highest IVU within the Araucanian community: Aloe (Aloe vera) (27%), peppermint (Mentha spicata) (14%), lemon mandarin (Citrus limonia) (13%), and chamomile (Matricaria chamomilla) (11%). The species with the highest UST corresponded to aloe (A. vera), with 50%, pericón (Capraria biflora) (45%), lemon grass (Cymbopogon citratus) (28%), hierba buena (M. spicata) (27%) and hierba mora (Solanum americanum) (22%). Discussion: Although the elderly of Arauca have important knowledge about the use of medicinal plants that contribute to improve the quality of health in the Araucanian community, it is necessary to validate the pharmacological, phytochemical and toxicological properties of the plant species used, since most of them have not been approved by INVIMA and in the approved ones, their use does not coincide appropriately with the endorsement of the surveillance institute.
