Potential anti-arthritic and analgesic properties of essential oil and viridiflorol obtained from Allophylus edulis leaves in mice. JOURNAL OF ETHNOPHARMACOLOGY 2023; 301:115785. [PMID: 36223847 DOI: 10.1016/j.jep.2022.115785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Revised: 09/21/2022] [Accepted: 09/29/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Viridiflorol was identified and isolated from the essential oil of Allophylus edulis leaves (EOAE). A. edulis was used as "tereré", which is a drink made by the infusion of herbs in cold water, to treat pain (toothache and headache). All anti-nociceptive (analgesic) and anti-arthritic properties of EOAE and viridiflorol have not been completely scientifically clarified. AIM OF THE STUDY The aim of the present study was to investigate the analgesic (anti-hyperalgesic and anti-nociceptive) and anti-arthritic properties of EOAE and viridiflorol using in vivo models. MATERIALS AND METHODS The oral administration (p.o.) of EOAE (30, 100 and 300 mg/kg), viridiflorol (30, 100 and 200 mg/kg), morphine (1 mg/kg, subcutaneous route (s.c.)) and the intraplantar (local) administration (i.pl.) of viridiflorol (100 μg/paw) were tested using formalin model in Swiss mice. EOAE (100 mg/kg, p.o.), viridiflorol (200 mg/kg, p.o.), and dexamethasone (1 mg/kg, s.c.) were tested by zymosan-articular inflammation and in open-field models. Viridiflorol (0.3, 20 and 200 μg/paw) was also tested in carrageenan model, and viridiflorol (200 μg/paw) was also tested in tumor necrosis factor-α (TNF-α), and dopamine (DOPA) models. RESULTS The oral administration of EOAE (100 and 300 mg/kg, p.o.), viridiflorol (200 mg/kg, p.o.), morphine (1 mg/kg, s.c.) (MOR) and local administration of viridiflorol (100 μg/paw) significantly inhibited edema and nociception in formalin model. Oral treatments with EOAE and viridiflorol (200 mg/kg) did not cause motor impairment in the open field test since they did not reduce locomotor activity. EOAE, viridiflorol and dexamethasone significantly reduced mechanical hyperalgesia, edema, total leukocytes, polymorphonuclear cells, nitric oxide and protein exudation in the zymosan-induced articular inflammation model. The local administration of viridiflorol (200 μg/paw, i.pl.) significantly inhibited mechanical hyperalgesia and edema induced by carrageenan, TNF-α and DOPA. CONCLUSIONS This study confirms the potential anti-arthritic, anti-nocicepttive and anti-hyperalgesic properties of EOAE and viridiflorol. These properties could explain, at least in part, the folk use of A. edulis against including pain (toothache and headache). Viridiflorol could be partially responsible for the EOAE anti-hyperalgesic, anti-nociceptive and anti-arthritic properties and its mechanism of action could involve the inhibition of TNF-α and DOPA pathways.

Kujawska M, Schmeda-Hirschmann G. The use of medicinal plants by Paraguayan migrants in the Atlantic Forest of Misiones, Argentina, is based on Guaraní tradition, colonial and current plant knowledge. JOURNAL OF ETHNOPHARMACOLOGY 2022; 283:114702. [PMID: 34627987 DOI: 10.1016/j.jep.2021.114702] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 09/28/2021] [Accepted: 09/29/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Information on the use of medicinal plants in the daily life by Paraguayan people is scarce in mainstream scientific literature. The study on the Paraguayan diaspora in the Provincia de Misiones, Argentina, gives an insight into Guaraní traditions, colonial legacy and current search for new medicinal plants to address new health challenges. AIM OF THE STUDY To document the use of medicinal plants by Paraguayan mestizo migrants who moved into a new country, yet within the same ecological region. The present and past uses of medicinal plants were compared to understand the continuity and change in the Paraguayan herbal pharmacopoeia. MATERIALS AND METHODS Fieldwork based on ethnographic and ethnobotanical techniques was carried out in the Provincia de Misiones, Argentina, in 2014, 2015, and 2019. Eighty-five Paraguayan migrants and their descendants from eastern Paraguay took part in the study. The list of recorded plants was compared with the information in historical sources from Paraguay, to examine the continuity and changes in Paraguayan herbal medicine, and with the present-day ethnobotanical studies from Paraguay. Ethnopharmacological and phytochemical studies on the medicinal plants with the highest consensus of uses were reviewed. RESULTS Altogether, 204 medicinal plant species were recorded. The most frequently mentioned species represented a combination of plants native to the New and Old World. Nearly 40% of the present-day Paraguayan pharmacopoeia shows continuity from colonial and post-colonial periods. Plants were used for 19 medical categories, of which digestive, circulatory and those belonging to humoral medicine were the most prevalent. The ongoing search of plants to treat new health problems is illustrated by reports of 40 species used for hypertension, 26 for diabetes and 18 to lower cholesterol. There is still little evidence for the effectiveness of these plants in the pharmacological literature. Paraguayan migrants were able to continue their traditional plant medicine in Misiones, Argentina, in a substantial way. CONCLUSION This study was carried out in a geographic area with a long-standing tradition of Guaraní medicine. Paraguayan migrants in Misiones integrate pre-Hispanic Guaraní names and uses of plants and old humoral concepts with current adaptation of plants to meet new health challenges. Several of the uses described in early colonial times are still practiced, giving a solid background for in-depth studies of the local pharmacopoeia.

Abstract
Diabetes mellitus (DM) is a metabolic disease that can affect the central nervous system and behavioral traits in animals. Streptozotocin-induced diabetes is considered an autoimmune disease. The aim of the current study was to determine whether supplementation with the alcoholic extract of Avicennia marina leaves could improve diabetes-associated pathological changes. The animals were divided into four groups: a control group (A), an A. marina receiving nondiabetic group (B), a diabetic group (C), and a DM group orally supplemented with A. marina alcoholic leaf extract (D). The DM group of animals receiving the alcoholic extract of A. marina leaves had reduced blood glucose levels, improved blood picture, and organ functions. This group also showed improvement in locomotory behavior. The results of this study showed that supplementation with the alcoholic extract of A. marina leaves reduced oxidative stress and blood sugar levels, protected the liver, and improved the neurobehavioral changes associated with diabetes in mice. Introducing alcoholic leaf extract of A. marina to diabetic mice decreased inflammatory cells aggregation, vacuolation, and hemorrhage. Additionally, a positive effect of the alcoholic leaf extract on the histopathological changes was observed in the testicular tissue of treated mice.

Ladio AH, Acosta M. Urban medicinal plant use: Do migrant and non-migrant populations have similar hybridisation processes? JOURNAL OF ETHNOPHARMACOLOGY 2019; 234:290-305.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Urban migrant herbal medicine is an important topic on a global scale. Through bibliographical analysis of published studies we can get an overview of the different hybridisation processes at work in cities around the world, the main medicinal plants used and the principal ailments treated. We analysed the differential characteristics of urban ethnobotanical studies involving transnational migrant and non-migrant populations, in order to contribute useful information for the design of public health policies. MATERIALS AND METHODS A systematic and integrative revision was conducted, leading to a final selection of 66 primary sources, including studies with and without immigrants. In both cases, richness (S), considered as the sum of all species cited in the work, botanical families and reported ailments were recorded. Based on the work of Ladio and Albuquerque (2014) the main hybridisation processes identifiable in the literature were assessed. These were: fusion, relocation, re-combination of different species, their restructuring as medicinal targets, spatial segregation in usage, innovations found in the circulation and consumption of the plants, and the presence of simultaneous coexistence of different symbolic universes in plant medical practices. DATA ANALYSIS This was qualitative and quantitative, including both in-depth interpretative content analysis of the studies and frequency analysis of numerical data, such as species richness, botanical families, ailments and the hybridisation processes detected. A multinomial logistic regression model was used to analyse whether the probability of medicinal plant hybridisation processes occurring was the same in literature with and without migrants. RESULTS A total of 522 medicinal species formed part of the main urban ethnobotany worldwide; the majority were cosmopolitan in distribution and belonged to the Asteriaceae and Lamiaceae families. Only 21% of these species appeared in both migrant and non-migrant studies. Most were used for gastrointestinal and hepatic ailments. Surprisingly, culture-related illnesses were not frequently mentioned, probably due to lack of recognition and re-interpretation by authors. Logistic analysis showed that in the studies with migrants, relocation and restructuring of plant use were the most frequently identified processes, while in the studies involving only non-migrants fusion was 4 times more likely to be found than in studies with migrants. CONCLUSIONS Our research on hybridisation processes shows that cities constitute an environment that fosters a rapid exchange of practices and knowledge about the available species. Studies with migrants have shown that they reproduce traditional models in their use of plants, and so relocation and restructuring of their herbal medicine are the principal processes. Health risks in this case are related to the difficulties faced by these groups in obtaining their plants and reproducing their practices. In the case of fusion processes observed in non-migrants, who do not normally have a long history or much experience of plant use, errors or poisoning may result from misuse. This information highlights the importance of considering these processes in health policies, particularly when there are no significant quality controls of these resources.

JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2018; 14:72. [PMID: 30466463 PMCID: PMC6249753 DOI: 10.1186/s13002-018-0270-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/25/2018] [Accepted: 11/02/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND Ethnopharmacological studies about migrants reveal a dynamic process of knowledge and use of medicinal plants. In this study, we sought to elucidate quantitative and qualitatively the main factors influencing the use of medicinal plants by migrants from rural areas to an urban region in Brazil with traces of remnant natural vegetation. METHODS Seven Northeastern individuals who migrated to the Southeastern Region of Brazil (Bororé Peninsula, in the city of São Paulo) were selected to participate in semi-structured interviews regarding the use of medicinal plants throughout their lives, and indicated an inhabitant in their hometown that would be able to accompany the field collections in each area. Socioeconomic, educational, family structure, and use of Western medicine data were provided during interviews with the individuals from their hometowns. Plant samples cited by the interviewees were collected both at the current place of residence and in their hometowns. RESULTS The participants cited 131 plants and 315 recipes, being the main indications related to the gastrointestinal system, respiratory problems, and pain and inflammatory processes. We observed that most plant uses were maintained after migration. Higher percentages of maintenances and incorporations in plant uses occurred to exotic species, while replacements happen mainly to native plants. The introduction of new species into the migrants' therapeutics occurred mainly by observations of organoleptic similarities between the substituted plant and the incorporated species, conversations with neighbors, and contact with the television and print media. In addition, the public health system allowed the interviewees access to prophylactic drugs, leading to the discontinuation of certain recipes used in endemic diseases. CONCLUSION Migrants were exposed to information about new plants and their uses, new diseases, and socioeconomic and cultural differences that impacted their use of medicinal plants. Although migration to a more developed city facilitated access to public health and education, on the other hand, it made access to fresh medicinal plants difficult, causing some medicinal plants to be replaced or ceased to be used.

Abstract
Although disparities in the burden of disease and illness experienced across major racial and ethnic groups in the USA is well known, little is known about subgroups, including the Hmong population. This review sought to determine the current state of health disparities related to health promotion and disease prevention among Hmong adults from 1975 to 2015. Seventy-one descriptive (qualitative, mixed methods, and quantitative) studies were reviewed. Most focused on two areas: (1) health status (mainly breast and cervical cancers) and (2) health-related behaviors. This literature review confirms the existence of health disparities related to health promotion and disease prevention in the Hmong adult population. Effective intervention relies on identifying these disparities. A possible explanation for these disparities is the lack of health data collected on subgroup populations, which include the Hmong adult population. More research and more comprehensive health policies at the organizational level are needed to allow data to be collected on subgroup populations in order to better understand the social determinants that place the Hmong people at risk.

ECONOMIC BOTANY 2018; 72:150-165. [PMID: 30369624 PMCID: PMC6182649 DOI: 10.1007/s12231-018-9417-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2017] [Accepted: 05/02/2018] [Indexed: 05/02/2023]
Abstract
Our research involves of how Paraguayan migrants who are living in Misiones, Argentina, manage medicinal plants in home gardens, and how this practice can be related to the landscape. We examine the relationship between the richness of home garden medicinal plants and landscape variables (e.g., distance to the forest) by applying PLS analysis, which combines principal component analysis with linear regression. We surveyed 60 home gardens localized in a rural area, and we characterized the surrounding landscape with geospatial tools. Paraguayans' home gardens are extremely diverse sites (total of 136 medicinal species), where both native (82) and introduced species (50) are managed. People who live close to the native forest or mixed use areas (e.g., farms, secondary vegetation) tend to possess less native plants in their gardens because they are available nearby. While gardeners, who live in proximity to tree crops (e.g., pine plantations), have reduced access to wild medicinal resources; therefore, their effort is concentrated on maintaining native plants. These results reflect a relationship between accessibility to medicinal plants in the landscape and the management practices in the home gardens, a neglected driver in explaining the richness and composition of the medicinal plants in home gardens so far. Thus, we contributed evidence in support of the environmental scarcity compensation hypothesis. Finally, our study supports the idea that home gardens appear to function as a springboard for plant domestication.

Abstract
Numerous studies highlight the importance of phytotherapy for indigenous and non-indigenous people in different parts of the world. In this work we analyze the richness (number of species), diversity (plant identity and the number of illnesses for which it is used) and similarity of plant species and illnesses treated with them, in order to contribute new data and insight into the importance of plant medicines to the local medical systems of people living in Misiones province, in the subtropics of Argentina. Three sympatric groups were compared: Guarani Indians, Criollos (mestizos) and Polish migrants. Quantitative scrutiny was focused on both primary and secondary sources. The similarity and diversity of medicinal plants and uses between groups was calculated by applying the Sørensen quantitative coefficient and the Shannon-Wiener index, respectively. In order to identify the characteristic plant species used by each group, the Cultural Importance and Prevalence Value (CIPV) was calculated based on the species Indicator Value (IndVal), which combines a species relative abundance with its relative frequency of occurrence in the various groups, and modified according to the type of the analyzed data. The important finding is a great variation in the number of species used by the study groups. Altogether, 509 botanical species were registered: Guarani (397), Criollos (243) and Polish migrants (137). For all groups, the use of native medicinal plants prevailed. The Guarani appear to be the local experts in use of medicinal plants. There is the significant difference in the number of treated illnesses by each taxon among three groups. Criollos and Polish migrants exhibit the greatest similarity in illnesses treated with medicinal plants. These groups share a corpus of knowledge related to illness nosology, and have a symptomatic approach to illness treatment. The Guarani have an etiological approach to illness diagnosis and healing, which may be viewed as a barrier to the exchange of knowledge about home medicine with other ethnic groups of Misiones.

Abstract
Context Worldwide ethnobotanical research has shown the importance of home gardens as sources of medicinal plants. These resources are worthy of further study in the Argentinean Atlantic Forest due to the richness of medicinal flora and their importance for local people. Objective We studied richness, composition, cultural importance and medicinal uses of plants in home gardens of rural, semirural and urban areas in the Iguazú Department (Misiones, Argentina). Our hypothesis claims that people living in different environments have a similar array of medicinal plants in their gardens and they use them in a similar way. Materials and methods The analysis was based on 76 interviews and plant inventories of home gardens. During guided walks in gardens, voucher specimens were collected. To analyse composition, Simpson similarity index was applied and a new index was proposed to measure culturally salient species. Results All the environments had similar species composition with species differing in less than 30% of them. The most culturally salient taxa were Mentha spicata L. (Lamiaceae), in rural, Artemisia absinthium L. (Asteraceae), in semirural, and Aloe maculata All. (Xanthorrhoeaceae), in urban areas. The body systems treated with medicinal plants were similar across study sites. Discussion The results suggest a "core repertoire" of medicinal plants and a widespread exchange of plants among local population. The cultural importance index informs us about plant adaptability, based on the efficacy and the versatility of medicinal resources. Conclusion In this changing context where mobility and migrations constitute everyday life, medicinal plants in home gardens are part of local healthcare sovereignty.

Abstract
Research has documented the influence of cultural values, beliefs, and traditional health practices on immigrants' health care utilization in their host countries. We describe our findings of how Hmong immigrants to the United States make decisions about whether and when to use traditional and/or Western health services. We conducted semi-structured interviews with 11 Hmong adults. We found their decisions depended on whether they classified the illness as spiritual or not and how they evaluated the effectiveness of different treatment options for their illness. Hmong participants' expectations for effective treatment in traditional or Western health care encounters combined with physical evidence of an illness influenced their decisions and often led them to shift from one type of care to the other. Understanding cultural differences in perceptions of the causes of illnesses and the link between perceived cause and treatment is important to improving care for the Hmong population.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Considerable medicinal plant research in Brazil has focused on indigenous and mixed-race (caboclo and caiçara) communities, but relatively few studies have examined the medicinal plants and associated healing traditions of the descendants of enslaved Africans. This study surveyed the medicinal plants employed by a relatively isolated maroon community of Afro-Brazilians in the Atlantic coastal rainforests of Bahia, Brazil, a global biodiversity hotspot. The studied community is exceptional in that the residents were defacto slaves until several years ago, with no access to western medicine. We examined the following questions: 1) What medicinal plants are used in this community? 2) What are the principal taxonomic groups, life forms, source habitats, and geographical origins? 3) What species stand out as measured by use value and frequency indices? and 4) Is the community's geographical isolation and African ancestry reflected in their medicinal uses of the local flora? MATERIALS AND METHODS The study was carried out in the Quilombo Salamina Putumuju maroon community in Bahia, Brazil. Data were collected from May to October 2014 from 74 individuals (37 men and 37 women) by means of semi-structured interviews, walk in the woods, and vouchering of identified species. We used the Cultural Value Index (CV), the Relative Frequency Index (RF), and the Use Value Index (UV) to determine the importance of medicinal plant resources. Continuity of African medicinal plant uses and traditions was determined through self-reporting and comparison with previously published works. RESULTS We recorded 118 medicinal plant species distributed in 100 genera and 51 families. The best represented families were: Asteraceae, Fabaceae, Lamiaceae and Myrtaceae. Most plant medicines were used to treat respiratory, digestive systems, genitourinary, and skin problems. The most common medicinal life form was herbs (44%), followed by trees (28%) and shrubs (18%). Native species (55%) were used somewhat more than exotic species (45%), and non-cultivated species (51%) were slightly more numerous than cultivated species (49%). In spite of abundant nearby old-growth forests, trails and gardens were the most common collection sites. A mean of 13.2 medicinal plant species were cited per participant. The highest CV was recorded for Cymbopogon citratus (0.20) followed by Lippia alba (0.19) and Stryphnodendron cf. adstringens (0.17). The highest RF included C. citratus (0.69), L. alba (0.59), and Eugenia uniflora (0.55). The highest UV figures were recorded for S. cf. adstringens (1.68), followed by Sida cf. cordifolia (0.97) and C. citratus (0.93).Fifteen species (13%) of this maroon medicinal flora trace their ancestry to Africa or African-derived healing traditions. CONCLUSION The Salamina maroon community maintains considerable knowledge of the medicinal value of the local flora. However, little of this knowledge is derived from the surrounding old-growth tropical forests. Their pharmacopoeia is a hybrid mix of wild and cultivated species, natives and exotics. Among those species representing the community's isolation and African ancestry, most are associated with spiritual and magical medicine.

Abstract
ETHNOBOTANICAL RELEVANCE Medicinal and food plants in the Basque Country are an integral part of a fast changing culture. With a distinct tradition and language, this region of Europe provides an important example demonstrating the changing role of local and traditional knowledge in industrial countries. As other Mediterranean regions it preserves a rich heritage of using plants as medicine and food, offering a unique opportunity for studying the medicine food interface in an ethnopharmacological context. Therefore, the key goal of this study has been to contribute to an understanding of local and traditional plant usage, to evaluate their uses as food and medicine as well as to critically assess the role of these plants in the south of the Basque Country contributing to an understanding of how foods and medicines are used. METHODS A mixed methods approach, including participant observation; open and semi structured interviews was used. Ethnobotanical field work included 183 people, ages ranged from 24 to 98 years old with a majority being between 70 and 80 years old (mean age 71) from 31 towns of three different regions. The basic interview was a one-to-one meeting, which often included field walking and collection of samples as directed by the informants. 700 voucher specimens (most of them with duplicates) were collected for the data obtained. Using SPSS version 20 the gathered information was processed and the replies of the different informants were subsequently organised in variables like medicine and food plants, part of the plants used, forms of preparations, zones preferred for collecting these plants. The data were analysed based on the frequency of records. This type of approach allows us to understand the way the informant's categorize the species, and how these categories are distributed along the sample. In order to analyse the data three main categories of use were distinguished: Medicine (M), Food (F) and an intermediate Health-Food (H-F). The three categories were divided in 27 subcategories (common uses). RESULTS AND DISCUSSION The informants recognise and use a total of 184 species from 49 families. During interviews, 5658 individual use-reports were collected relating to three use-categories - as medicines, food and health-food. The two main groups with almost the same number of species each are health-food (75 species) and (locally gathered) food only (73), with medicinal uses only (36) being the smallest group. This highlights the important overlap between food and medicines. Overall, three core families were identified (based on the number of use reports and in the number of species): Asteraceae (25 species), Lamiaceae and Rosaceae (24 each). The most frequently reported species are Jasonia glutinosa, Chamaemelum nobile, Prunus spinosa and Quercus ilex subsp. ballota. The most important general use-subcategories are as raw vegetables (27.43% of the use-reports and including 81 species), infusions (14.74%/42) and gastrointestinal (12.53%/42). Conceptually foods and medicines are clearly distinguished but the intermediate group of health foods is more ambiguous. CONCLUSION Food and medicinal uses of plants are culturally closely linked. A wide range of plants are known and many still used. The analysis shows that the Basques use a wide range of species which are typical for Western European cultures. In comparison to other studies in the Mediterranean countries there are many similarities in the uses of different families, species of plants and their use and preparations. Some of these plants are key Mediterranean species, often used for a multitude of uses as food and medicine.
