RESUMO
A vegetação da Caatinga é rica em uma diversidade de espécies vegetais utilizadas para satisfazer as necessidades humana. Muitas dessas espécies são utilizadas para fins terapêuticos por populações. As formas de uso dessas espécies podem ser registradas e resgatadas através de estudos etnobotânicos, os quais contribuem no levantamento das potencialidades dos recursos vegetais, bem como em planos de recuperação e conservação da vegetação. Assim, com base em uma revisão integrativa, o presente trabalho buscou copilar informações sobre como os trabalhos de etnobotânica das plantas medicinais estão sendo desenvolvidos, assim como a respeito das principais espécies e famílias botânicas de potencial medicinal descritas, em levantamentos realizados em áreas caatinga localizadas na região semiárida do Nordeste. Para isso, foram selecionados artigos publicados entre os anos de 2010 e 2022, que abordassem a temática relacionada. Foram considerados trabalhos publicados no formato de artigos originais, disponíveis de forma online, gratuito e completo, em língua portuguesa e inglesa. Esses artigos foram consultados em diferentes bases de dados. A análise integrativa evidenciou as características das publicações, como a concentração de estudos direcionados aos estados da Bahia, Paraíba e Pernambuco, bem como demonstrou uma rica diversidade de plantas medicinais que são utilizadas pela população no semiárido nordestino, destacando-se, principalmente, os saberes tradicionais sobre as suas formas de uso e propriedades terapêuticas.
The Caatinga vegetation is rich in a diversity of plant species used to satisfy human needs. Many of these species are used for therapeutic purposes by populations. The forms of use of these species can be registered and rescued through ethnobotanical studies, which contribute to the survey of the potential of plant resources, as well as plans for the recovery and conservation of vegetation. Thus, based on an integrative review, the present work sought to compile information on how ethnobotany works on medicinal plants are being developed, as well as on the main species and botanical families with medicinal potential described, in surveys carried out in caatinga areas located in the semi-arid region of the Northeast. For this, articles published between the years 2010 and 2022 that addressed the related theme were selected. Works published in the format of original articles, available online, free and complete, in Portuguese and English, were considered. These articles were consulted in different databases. The integrative analysis showed the characteristics of the publications, such as the concentration of studies directed to the states of Bahia, Paraíba and Pernambuco, as well as demonstrating a rich diversity of medicinal plants that are used by the population in the northeastern semi-arid region, highlighting, mainly, the knowledge traditional practices about their forms of use and therapeutic properties.

ETHNOPHARMACOLOGICAL RELEVANCE: Mayaro virus (MAYV) is an arbovirus endemic to the Amazon region, which comprises the states of the North and Midwest region of Brazil and encompasses the largest tropical forest in the world, the Amazon Forest. The confirmation of its potential transmission by Aedes aegypti and recent cases in Brazil, mainly in large centers in the northern region, led to the classification of Mayaro fever as an emerging disease. Traditional medicine is commonly used to treat various diseases, mainly by local riverside populations. Some species of the genus Maytenus, which have similar morphologies, are popularly used to treat infections and inflammations. In this context, our research group has studied and confirmed the antiviral activity of several plant-derived compounds. However, several species of this same genus have not been studied and therefore deserve attention. AIM OF THE STUDY: This study aimed to demonstrate the effects of ethyl acetate extracts of leaves (LAE) and branches (TAE) of Maytenus quadrangulata against MAYV. MATERIALS AND METHODS: Mammalian cells (Vero cells) were used to evaluate the cytotoxicity of the extracts. After cell infection by MAYV and the treatment with the extracts, we evaluated the selectivity index (SI), the virucidal effect, viral adsorption and internalization, and the effect on viral gene expression. The antiviral action was confirmed by quantifying the viral genome using RT-qPCR and by analyzing the effect on virus yield in infected cells. The treatment was performed based on the effective concentration protective for 50% of the infected cells (EC50). RESULTS: The leaves (LAE; EC50 12.0 µg/mL) and branches (TAE; EC50 101.0 µg/mL) extracts showed significative selectivity against the virus, with SI values of 79.21 and 9.91, respectively, which were considered safe. Phytochemical analysis revealed that the antiviral action was associated with the presence of catechins, mainly in LAE. This extract was chosen for the subsequent studies since it reduced the viral cytopathic effect and virus production, even at high viral loads [MOI (multiplicity of infection) 1 and 5]. The effects of LAE resulted in a marked reduction in viral gene expression. The viral title was drastically reduced when LAE was added to the virus before infection or during replication stages, reducing virus production up to 5-log units compared to infected and untreated cells. CONCLUSION: Through kinetic replication, MAYV was not detected in Vero cells treated with LAE throughout the viral cycle. The virucidal effect of LAE inactivates the viral particle and can intercept the virus at the end of the cycle when it gains the extracellular environment. Therefore, LAE is a promising source of antiviral agents.

The current COVID-19 pandemic, characterized by a highly contagious severe acute respiratory syndrome, led us to look for medicinal plants as an alternative to obtain new drugs, especially those with immunomodulatory abilities, capable of acting against the pulmonary infection caused by coronavirus 2 (SARS-CoV-2). Despite medical advances with COVID-19 drugs and vaccines, plant-based compounds could provide an array of suitable candidates to test against this virus, or at the very least, to alleviate some symptoms. Therefore, this review explores some plants widely used in Peru that show immunomodulatory properties or, even more, contain phytoconstituents potentially useful to prevent or alleviate the COVID-19 infection. More interestingly, the present review highlights relevant information from those plants to support the development of new drugs to boost the immune system. We used three criteria to choose nine vegetal species, and a descriptive search was then conducted from 1978 to 2021 on different databases, using keywords focused on the immune system that included information such as pharmacological properties, phytochemical, botanical, ethnobotanical uses, and some clinical trials. From these literature data, our results displayed considerable immunomodulation activity along with anti-inflammatory, antiviral, antioxidant, and antitumoral activities. Noticeably, these pharmacological activities are related with a wide variety of bioactive phytoconstituents (mixtures or isolated compounds) which may be beneficial in modulating the overt inflammatory response in severe COVID-19. Further scientific research on the pharmacological activities and clinical utilization of these potential plants are warranted. Supplementary Information: The online version contains supplementary material available at 10.1007/s43450-023-00367-w.
RESUMO
In southern Brazil, the biodiversity is great and the traditional use of medicinal plants for wound healing has been documented in ethnobotanical studies and pharmacological studies have assessed their wound properties and phytochemistry. Therefore, this study evaluated ethnobotanical surveys regarding medicinal plants used in southern Brazil for wound healing and studies about the healing properties of these plants published between 2000 and 2022. To retrieve articles related to the study, Web of Science, PubMed (NLM), Open Access Journals, Scielo, Lilacs, and Google Scholar, with keywords including medicinal plants, wound healing, and South of Brazil, have been used. As a result, 73 medicinal plants belonging to 39 families were found in ethnobotanical surveys as a traditional resource used for wound healing in southern Brazil, 15 of which were cited more than once. Besides, 14 of these 15 plants were also used as healing agents worldwide. The most cited plant with healing actions in southern Brazil was Symphytum officinale L. (comfrey). From 2000 to date, 44 articles scientifically demonstrated the wound-healing effects of the southern Brazilian plants found in ethnobotanical surveys reviewed. The folk medicine of southern Brazil presents a variety of medicinal plants for wound-healing purposes, and scientific data were found for some of those plants. However, the wound-healing properties of many plants have yet to be investigated, and the current literature still needs more phytochemical information about the plants studied. Aside from this, the future focus should be on the standardization of herbal extracts, and further research is required to investigate the pharmacological mechanisms. Clinical research in this area remains in its infancy and warrants more robust further clinical studies.

Baccharis dracunculifolia DC (Lamiaceae) (Asteraceae) is found in South America, mainly in Argentina, Brazil, Bolivia, Paraguay and Uruguay. Folk medicine is used as a sedative, hypotensive, bronchodilator, cardiovascular disorders, anti-flu, and also in skin wounds. Considered the main source of green propolis, which increases the pharmacological interest in this species. It is also known as a "benefactor" plant facilitating the development of other plant species around it, being indicated for the recovery of degraded areas. This species has been studied for decades in order to isolate and identify the active principles present in the aerial parts (leaves and flowers) and roots. The present study consists of a review of the scientific literature addressing the ethnobotanical, ethnomedicinal, phytochemical, pharmacological and potential cytotoxic effects of the B. dracunculifolia species. In this survey, we sought to investigate issues related to the botanical and geographic description of the species, the ethnobotanical uses, as well as the phytochemical studies of the essential oil, extracts and green propolis obtained from the aerial parts and roots of B. dracunculifolia. Using high precision analytical tools, numerous compounds have already been isolated and identified from leaves and flowers such as the flavonoids: naringenin, acacetin, dihydrokaempferol, isosakuranetin and kaempferide; phenolic acids: p-coumaric, dihydrocoumaric, ferulic (E)-cinnamic, hydroxycinnamic, gallic, caffeic, and several caffeoylquinic acids derivatives; phenolic acids prenylated: artepillin C, baccharin, drupanin; the glycosides dracuculifosides and the pentacyclic triterpenoids: Baccharis oxide and friedelanol. The predominant class in the essential oil of leaves and flowers are terpenoids comprising oxygenated monoterpenes and sesquiterpenes, highlighting the compounds nerolidol, spathulenol, germacrene D and bicyclogermacrene. These compounds give the species high antimicrobial, antioxidant, antitumor, analgesic, immunomodulatory and antiparasitic potential, making this species a promising herbal medicine. In vitro toxicity assays with B. dracunculifolia extract showed low or no cytotoxicity. However, in vivo analyses with high doses of the aqueous extract resulted in genotoxic effects, which leads us to conclude that the toxicity of this plant is dose-dependent.
RESUMO
Snakebite envenoming is a potentially fatal disease categorized as a neglected public health issue for not receiving the appropriate attention from national and international health authorities. The most affected people by this problem usually live in poor rural communities, where medical resources are often sparse and, in some instances, there is even a scarcity of serum therapy. The administration of the appropriate antivenom is the only specific treatment available, however it has limited efficacy against venom-induced local effects. In this scenario, various plant species are used as local first aid for the treatment of snakebite accidents in Brazil, and some of them can effectively inhibit lethality, neurotoxicity, hemorrhage, and venom enzymes activities. This review compiles a list of plants used in the treatment of snakebites in Brazil, focusing on the native Brazilian species registered in the databases Pubmed, Scielo, Scopus and Google Scholar. All these searches were limited to peer-reviewed journals written in English, with the exception of a few articles written in Portuguese. The most cited native plant species were Casearia sylvestris Sw., Eclipta prostrata (L.) L., Mikania glomerata Spreng., Schizolobium parahyba (Vell.) S.F.Blake and Dipteryx alata Vogel, all used to decrease the severity of toxic signs, inhibit proteolytic and hemorrhagic activities, thus increasing survival time and neutralizing myotoxicity effects. Different active compounds showing important activity against the snake venoms and their toxins include flavonoids, alkaloids and tannins. Although some limitations to the experimental studies with medicinal plants were observed, including lack of comparison with control drugs and unknown active extracts compounds, species with anti-venom characteristics are effective and considered as candidates for the development of adjuvants in the treatment of snake envenomation. Further studies on the chemistry and pharmacology of traditionally used plant species will help to understand the role that snakebite herbal remedies may display in local medical health systems. It might also contribute to the development of alternative or complementary treatments to reduce the number of severe disabilities and deaths.

Resumen Objetivos: El estudio pretende reconocer la existencia de agentes portadores y reproductores de prácticas y saberes populares en salud, sus dominios y dinámica en el espacio social. Georreferenciar sus dinámicas y establecer su relación con el Plan Básico de Ordenamiento Territorial. Metodología: Estudio cualitativo analítico, que conjuga la geografía crítica y la etnografía. Mediante el uso de técnicas de georreferenciación, -localización y espacialización-, con uso del software QGIS versión 3.6 Nossa. Y mediante el uso de técnicas de entrevistas a profundidad y observaciones documentadas, información que se ordenó y sistematizó por categorías, mediante la implementación del programa ATLAS.ti versión 9. Resultados: Se reconocieron más de 60 agentes y se localizaron 48. Se reconocen dos dominios del saber popular: el mágico religioso, expresado en sobanderos con secreto, y el curanderismo expresado en hierbateros, rezanderos y sobanderos. Se legitiman a través de su presencia en espacios sociales, en sus tres dimensiones: material, al portar una identidad y un dominio, que habitan con objetos; mental, el cual cargan de relaciones y simbolismos; y político, donde reproducen una cadena comercial vinculada a la zona de vocación comercial establecida por el PBOT del municipio. Conclusiones: Los agentes, sus prácticas y saberes se determinan y legitiman, a partir de actos de reproducción social, cultural y política en el territorio como espacio social, y en sus dimensiones, a partir de expresiones culturales, simbolismos y rituales, relaciones materiales a partir del intercambio con objetos y servicios, y su asiento político en las zonas de vocación territorial.
Abstract Objectives: The study aims at recognizing the existence of agents carrying and reproducing popular practices and knowledge in health, their domains and dynamics in the social space and at geo-positioning their dynamics and establishing their relationship with the Basic Plan of Territorial Planning. Methodology: qualitative analytical study that combines critical geography through georeferencing techniques, -localization and spatialization-, using the QGIS Version 3.6 Nossa program, and ethnography through the use of in-depth interview techniques and observations, information that was organized and systematized by categories through the implementation of the ATLAS.ti version 9 program. Results: More than 60 agents were recognized and 48 were located. Two domains of popular knowledge were recognized: the Religious Magic, expressed in massage therapists (sobanderos) with secrecy, and folk medicine (Curanderismo) expressed in shamans, rezanderos and sobanderos. They are legitimized through their presence in social spaces in their 3 dimensions: material by carrying an identity and a domain inhabiting objects; mental which is loaded with relationships and symbolism; and political where they reproduce an overlapping and expanded commercial chain, linked to the area of commercial vocation delimited by the PBOT of the municipality. Conclusions: Agents, their practices and knowledge are determined and legitimized based on acts of social, cultural and political reproduction in the territory as a social space, and in their dimensions based on cultural expressions, symbolisms and rituals, material relationships from the exchange with objects and services and settled politically in the areas of territorial vocation.

RESUMO
Introducción. Existen estudios que dan cuenta del uso extendido de la medicina tradicional (MT) en diversos países. La formación del pediatra es escasa en este campo. Objetivo. Describir las características de la MT utilizada por los pacientes de un hospital pediátrico de la Ciudad Autónoma de Buenos Aires. Población y métodos. Diseño cualitativo, basado en la teoría fundada. Entrevista a cuidadores de niños de 0 a 11 años. Resultados. Se entrevistaron 30 personas de diferentes colectividades, la gran mayoría mujeres amas de casa. Casi la totalidad refirió haber utilizado la MT. La fuente de recomendación más utilizada fue la familia. En general, el uso de la MT precede a la consulta a un médico del sistema de salud. Se acude a la MT por entidades definidas por la medicina convencional, pero también por otras propias, como pata de cabra, ojeo y empacho. Las prácticas terapéuticas incluyen la administración de preparados a base de plantas, infusiones, caldos, como también rituales conducidos por curanderos. Todos los usuarios refirieron una valoración positiva de la MT. Una gran parte de los entrevistados consideró importante que el médico conozca y pregunte sobre ella. Todos refirieron que su uso no fue abordado en consultas previas. Conclusiones. La MT se extiende como conocimiento y/o práctica en toda la población estudiada y forma parte de su vida cotidiana. Los métodos utilizados son muy diversos, así como las situaciones para las que se utiliza; las principales causas son de origen gastrointestinal y respiratoria. No es abordada en la consulta pediátrica, pero sus usuarios desearían que lo fuera.
Introduction. Several studies have reported on the widespread use of traditional medicine (TM) in different countries. Pediatricians receive scarce training in this field. Objective. To describe the characteristics of TM used by patients attending a children's hospital in the City of Buenos Aires. Population and methods. Qualitative design based on grounded theory. Interview with caregivers of children aged 0-11 years. Results. Thirty people from different communities were interviewed, mostly homemakers. Almost all referred having used TM. The most common source of recommendation was the family. In general, TM use precedes the visit to a physician in the health system. TM is used to manage conditions defined by conventional medicine, but also to treat folk illnesses such as Simeon's disease, evil eye, and indigestion. Therapeutic practices include plant-based preparations, infusions, broths, as well as other rituals performed by folk healers. All users had a positive opinion about TM. Most interviewees considered that physicians should know and ask about TM. All participants referred that its use had not been addressed in prior visits. Conclusions. TM spreads as knowledge and/ or practice across the studied population and is part of everyday life. TM methods vary greatly, as well as the conditions for which it is used; the main reasons for use included gastrointestinal and respiratory conditions. It is not addressed in pediatric visits, but users wish it was.

The native flora of Brazil covers a large biodiversity of plants, some of which have important pharmacological properties. Ethnobotanical studies have established that the folk use of plants for hepatobiliary disorders is very common in Brazil. This review aimed to compile, describe and discuss the main native Brazilian medicinal plants used as hepatoprotective agents listed on 25 books by authors from various regions in the country. Based on the 153 species found, a comprehensive analysis of the most relevant scientific studies is presented, including Piper umbellatum, Echinodorus macrophyllus, Fevillea trilobata and Achyrocline satureioides. Some medicinal plants share both a large number of citations and scientific evidence to corroborate their hepatoprotective effects, including Solanum paniculatum, Baccharis crispa and Phyllanthus niruri, which could be of interest to develop new phytomedicines. Additionally, some active ingredients are indicated as being responsible for the liver protective effects described, particularly phenolic compounds (flavonoids, coumestans and lignans).

The aim of this research is to make a survey of the socio-environmental characteristics and the ethnobotanical study of medicinal plants used in a traditional community in the Brazilian Northeast, Alagoas. The study was made based on visits with the application of a questionnaire with questions related to the socio-economic element and on the diversity of plants used in herbal medicine. The research was made from March/2019 to February/2020, where families and interviewed plant exhibitors were interviewed for botanical identification. The studied community, which were 24 interviewees, was compiled by residents of the Quilombola community from Pau D'arco in Arapiraca city - Alagoas. Residents interviewed, 15 (62.5%) attended between 56 to 80 years, 11 interviewees about 46% were born in the community and 13 (54%) had a fundamentally incomplete nature. At the end, there were mentioned 30 plant species used for phytotherapeutic purposes, from which presents bigger usage as plants against arterial hypertension (Salvia rosmarinus Schleid), diabetes Mellitos (Croton heliotropiifolius Kunth), pain and inflammation (Alternanthera tenella Colla), present the biggest number of species in the community. The species cited are related to numerous medicinal uses, among which there will be predominant associations associated with cardiovascular and inflammatory processes. The tea is the main way of preparing plants. It is perceived that medicinal plants are only widely used by this Quilombola community of and growth of the crops in the backyard are considered a tradition.

RESUMO
The aim of this research is to make a survey of the socio-environmental characteristics and the ethnobotanical study of medicinal plants used in a traditional community in the Brazilian Northeast, Alagoas. The study was made based on visits with the application of a questionnaire with questions related to the socio-economic element and on the diversity of plants used in herbal medicine. The research was made from March/2019 to February/2020, where families and interviewed plant exhibitors were interviewed for botanical identification. The studied community, which were 24 interviewees, was compiled by residents of the Quilombola community from Pau D'arco in Arapiraca city - Alagoas. Residents interviewed, 15 (62.5%) attended between 56 to 80 years, 11 interviewees about 46% were born in the community and 13 (54%) had a fundamentally incomplete nature. At the end, there were mentioned 30 plant species used for phytotherapeutic purposes, from which presents bigger usage as plants against arterial hypertension (Salvia rosmarinus Schleid), diabetes Mellitos (Croton heliotropiifolius Kunth), pain and inflammation (Alternanthera tenella Colla), present the biggest number of species in the community. The species cited are related to numerous medicinal uses, among which there will be predominant associations associated with cardiovascular and inflammatory processes. The tea is the main way of preparing plants. It is perceived that medicinal plants are only widely used by this Quilombola community of and growth of the crops in the backyard are considered a tradition.

The medicinal uses of Calotropis procera are diverse, yet some of them are based on effects that still lack scientific support. Control of diabetes is one of them. Recently, latex proteins from C. procera latex (LP) have been shown to promote in vivo glycemic control by the inhibition of hepatic glucose production via AMP-activated protein kinase (AMPK). Glycemic control has been attributed to an isolated fraction of LP (CpPII), which is composed of cysteine peptidases (95%) and osmotin (5%) isoforms. Those proteins are extensively characterized in terms of chemistry, biochemistry and structural aspects. Furthermore, we evaluated some aspects of the mitochondrial function and cellular mechanisms involved in CpPII activity. The effect of CpPII on glycemic control was evaluated in fasting mice by glycemic curve and glucose and pyruvate tolerance tests. HepG2 cells was treated with CpPII, and cell viability, oxygen consumption, PPAR activity, production of lactate and reactive oxygen species, mitochondrial density and protein and gene expression were analyzed. CpPII reduced fasting glycemia, improved glucose tolerance and inhibited hepatic glucose production in control animals. Additionally, CpPII increased the consumption of ATP-linked oxygen and mitochondrial uncoupling, reduced lactate concentration, increased protein expression of mitochondrial complexes I, III and V, and activity of peroxisome-proliferator-responsive elements (PPRE), reduced the presence of reactive oxygen species (ROS) and increased mitochondrial density in HepG2 cells by activation of AMPK/PPAR. Our findings strongly support the medicinal use of the plant and suggest that CpPII is a potential therapy for prevention and/or treatment of type-2 diabetes. A common epitope sequence shared among the proteases and osmotin is possibly the responsible for the beneficial effects of CpPII.
RESUMO
Early plants began colonizing earth about 450 million years ago. During the process of coevolution, their metabolic cellular pathways produced a myriad of natural chemicals, many of which remain uncharacterized biologically. Popular preparations containing some of these molecules have been used medicinally for thousands of years. In Brazilian folk medicine, plant extracts from the bamboo plant Guadua paniculata Munro have been used for the treatment of infections and pain. However, the chemical basis of these therapeutic effects has not yet been identified. Here, we performed protein biochemistry and downstream pharmacological assays to determine the mechanisms underlying the anti-inflammatory and antinociceptive effects of an aqueous extract of the G. paniculata rhizome, which we termed AqGP. The anti-inflammatory and antinociceptive effects of AqGP were assessed in mice. We identified and purified a protein (AgGP), with an amino acid sequence similar to that of thaumatins (~20 kDa), capable of repressing inflammation through downregulation of neutrophil recruitment and of decreasing hyperalgesia in mice. In conclusion, we have identified the molecule and the molecular mechanism responsible for the anti-inflammatory and antinociceptive properties of a plant commonly used in Brazilian folk medicine.

Barriers to health care access faced by Mexican immigrants in the United States have been well-documented, including lack of insurance, fear of deportation, and language barriers. However, little is known about this population's care-seeking experiences before migration. In this article, I use a life-course approach to explore binational isolation from health care and the ways in which early-life experiences pattern Mexicans' care-seeking practices in the United States. This ethnographic research project took place in Tucson, Arizona, between 2013 and 2014 and used semistructured interviews with service providers and first-generation Mexican immigrants. The majority of participants faced significant barriers to medical care in Mexico, which resulted in low rates of care utilization and heavy reliance on lay modalities. Immigrants faced an even broader array of barriers to care in the United States, and their lack of prior health care access further discouraged care utilization and compromised their medical care experiences after migration.

BACKGROUND: Solanum lycocarpum is a medicinal plant used in Brazil with hypoglycemic activity by its fruits use. However, the fruits production is restricted in some periods of the year, differently of leaves. OBJECTIVE: To evaluate the effects of hydroalcoholic extracts of S. lycocarpum leaves in alloxan-induced diabetic mice. METHODS: Hydroalcoholic extract of S. lycocarpum was characterized by phytochemical and GCMS analysis. The Antidiabetic activity was assessed following treatment for 22 days with S. lycocarpum extract at 125, 250, and 500 mg/kg. Bodyweight, water, and food intake, glycemia, biochemical parameters, anatomy-histopathology of the pancreas, liver and kidney, and expression of target genes were analyzed. In addition, oral acute toxicity was evaluated. RESULTS: Animals treated showed a significant reduction (p < 0.05) in glycemia following a dose of 125 mg/kg. Food intake remained similar for all groups. Decreased polydipsia symptoms were observed after treatment with 250 (p < 0.001) and 500 mg/kg (p < 0.01) compared with diabetic control, although normal rates were observed when 125 mg/kg was administered. A protective effect was also observed in the pancreas, liver, and kidneys, through the regeneration of the islets. Hypoglycemic activity can be attributed to myo-inositol, which stimulates insulin secretion, associated with α-tocopherol, which prevents damage from oxidative stress and apoptosis of ß-pancreatic cells by an increased Catalase (CAT) and Glutathione peroxidase 4 (GPX4) mRNA expression. The toxicological test demonstrated safe oral use of the extract under the present conditions. CONCLUSION: Hydroalcoholic extract of S. lycocarpum promotes the regulation of diabetes in the case of moderate glycemic levels, by decreasing glycemia and exerting protective effects on the islets.

Aniba canelilla (Kunth) Mez, popularly known as "casca preciosa" (precious bark), falsa canela (cinnamon-scented) Casca-do-maranhão (bark of maranhão), and Folha-preciosa (precious leaf), is an aromatic species of the Lauraceae family, widely distributed in the Amazon region. In traditional medicine, it is indicated for the treatment of a great diversity of diseases, including digestive, respiratory, inflam]matory, painful, and central nervous system disorders, it is administered mainly in the form of tea or decoction orally. Its essential oil is referred to as a natural antioxidant for food preservation and disease control, showing great potential for use in the cosmetics, perfumery, and pharmaceutical products sector. The present review aimed to discuss critically and comprehensively the ethnobotanical characteristics, phytochemical constitution, and scientifically tested biological properties of A. canelilla, systematizing the knowledge about the species and proposing new perspectives for research and development. The chemical composition of A. canelilla includes 1-nitro-2-phenylethane, metyleugenol, eugenol, safrol, anabasin, anbin, tannin, α-pinene, b-pinene, b-felandren, b-caryophyllene, b-sesquifelandren, p-cymene, linalool, α-copaene, and spatulenol. Researches with ethanolic extracts, essential oils, and major constituents (1-nitro-2-phenylethane and metyleugenol) have revealed antioxidant, antinociceptive, anti-inflammatory, cardio-modulating, hypotensive (vasorelaxant), hypnotic, anxiolytic, anticholinesterase, and antibiotic properties (trypanomicidal, leishmanicidal, and antifungal). Some of these effects are potentially beneficial for aging-related diseases treatment, such as cardio and cerebrovascular, chronic inflammatory, neurological, and degenerative diseases. However, it is necessary to advance in the research of its clinical use and development of therapeutic products.
