A diethyl ether extract of Jatropha multifida showed the presence of 16-hydroxyphorbol. . The Naranjo algorithm [176], which consists of 10 questions that address the factors considered to determine the causal relationship in case reports, was used to assess causality. Numerous habitats including rainforest, pine forest, savanna, marsh, and mangrove support nearly 3,500 species of vascular plants. A Prosopis juliflora seedcase added at 70% to the diet of pregnant rats resulted to be teratogenic (13-fold) compared to the untreated group [172]. [189] reported six fatalities in patients who ingested between 1 and 10 seeds of T. peruviana. We documented 104 plant species belonging to 55 families that have been used as immunostimulants. These include the ethanol extract of Phoradendron serotinum leaves tested on peripheral blood mononuclear cells [91], the aqueous extract of Cnidoscolus chayamansa leaves on baby hamster kidney (BHK) cells [92], and the aqueous extract of Enterolobium cyclocarpum bark assayed on 3T3 murine preadipocytes [82]. The guideline 423 of the Organization for Economic Cooperation and Development (OECD) establishes that substances with an LD50 < 5 mg/kg are highly toxic, whereas LD50 values from 5 to 50 mg/kg are very toxic, LD50 values from 50 to 300 mg/kg are toxic, LD50 values from 300 to 2000 mg/kg are dangerous, and LD50 values higher than 2000 mg/kg are not dangerous [104]. and mice (treated with doses ranging 375–3275 mg/kg) received an aqueous extract of Hydrastis canadensis root for 2 years (106 weeks). Belize lies on the Caribbean coast of Central America, bordered by Mexico to the north and Guatemala to the west. Jatropha curcas, Andira inermis, and Canella winterana were the third, the fourth, and the fifth most cited plant species, respectively, associated with cases of toxicity in Cuba from 1998–2007 [36]. in mice, whereas its active compound affinin had an LD50 = 113.13 mg/kg p.o. No deaths were reported. V. Hall-Ramírez, M. Rocha-Palma, and E. Rodriguez-Vega, L. Arteaga Figueroa, L. Barbosa Navarro, M. Patiño Vera, and V. L. Petricevich, “Preliminary studies of the immunomodulator effect of the, E. Rengifo-Salgado, “Contribución de la etnomedicina. Therefore, the discovery of agents which enhance the immune system represents an attractive alternative to the inhibition of tumor growth and the prevention and treatment of some infections. Aristolochia (6 plant species), Euphorbia (6 plant species), Solanum (5 plant species), and Asclepias (5 plant species) are the plant genera most often reported to induce toxicity (Table 1). Retrouvez Peterson Field Guide to Medicinal Plants and Herbs of Eastern and Central North America, Third Edition et des millions de livres en stock sur Amazon.fr. Additional data were acquired from undergraduate and postgraduate theses, as well as published and electronic books. In another case, the prevalence of toxicity by medicinal plants was also reported. The immunostimulatory activity of plant extracts or compounds in combination with a known immunostimulant agent (such as lipopolysaccharide, CD3) was omitted in this review. The Forager's Harvest: A Guide to Identifying, Harvesting, and Preparing Edible Wild Plants Samuel Thayer. In addition, histological examinations of the spleen, kidney, and liver showed no abnormalities. Therefore, the identification of toxic principles in medicinal plants is necessary. Fresh leaves of Prunus serotina, used for the treatment of cough, or Zanthoxylum fagara, an anxiolytic agent, each must be consumed in a maximum quantity of five leaves in 250 ml of water per day. One of my goals is to find legitimate, reputable healers, herbalists, bush doctors, shamen or medicine people to contact, talk to and possibly study with on a future trip. The clinical pattern consists of neuropathy and hyperthyroidism [192]. Answer 1 of 6: My party is going overland from Mexico to Costa Rica next April. Additionally, the ethanol extract of Equisetum hyemale aerial parts evaluated on rabbit corneal fibroblasts (SIRC) [93], the methanol extract of Enterolobium cyclocarpum leaves evaluated on Vero cells (obtained from kidney epithelial cells extracted from the African green monkey (Cercopithecus aethiops) [88], and the diterpene ent‐kaur‐16‐en‐19‐oic acid, obtained from Annona cherimola, tested on rat embryo primary striatal cultures [94]. The aim of this study is to review the medicinal plants used to treat diabetes and its sequelae in seven Central American countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama. The following plant extracts and compounds can be considered very toxic (5–50 mg/kg) [104]: the free alkaloid fraction in hexane and methanol extracts from Erythrina americana seeds (LD50 = 38.54 to 40.37 mg/kg i.p.) y Heliotropium indicum L,”, M.

We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. Nevertheless, there were effects in the lungs and testis [120]. Li, R. K. Devappa, J.-X. The interaction of herbal extracts and drugs remains to be studied. In: VandebroekI JB, Calewaert S, De jonckheere SS; Lucio S, Van Damme P, Van Puyvelde L, De Kimpe N: Use of medicinal plants and pharmaceuticals by … Locklear T.D. Therefore, the common names were given in Spanish (Table 1). This was confirmed, for many plant species, by consulting our previous work [94]. For instance, Xanthium strumarium is considered a toxic plant. Organization for Economic Cooperation and Development, A. S. Awaad, N. A. Al-Jaber, G. A.

Among the in vivo studies, an ethanol extract from Phoradendron serotinum leaves, tested from 1 to 10 mg/kg i.p., showed immunostimulatory effects, in a dose-dependent manner, by increasing the levels of IFN-γ, IL-2, and IL-6 in serum from C57BL/6 mice bearing TC-1 tumor [41]. Capsaicin (5–100 mg/kg p.o.) Ethanol extract of Phoradendron serotinum leaves had an LD50 = 125 mg/kg i.p. This method evaluates the temporal relationship between the consumption of a substance (drug or natural remedy) and the appearance of hepatic damage, the absence or presence of risk factors, the exclusion of alternative causes of liver injury, among others. Medicinal plants are increasingly well regarded as supplements and sometimes as alternatives for prescription drugs. A methanol extract of Indigofera suffruticosa aerial parts (1.25–7.5 mg/plate) showed mutagenic activity in a Salmonella microsome assay [97]. . did not affect organ body weight or hematological parameters but decreased the levels of ALT in rats after 7 days of treatment at all doses [126]. Dr. Nicole Apelian, finally managed to collect all remedies and medicinal plants of North America and included them in one Book. 2-3, pp. A methanol extract of Rauvolfia tetraphylla leaves did not affect hematological parameters. Interferon gamma (IFN-γ), mainly produced by NK cells, exerts antitumor and antiviral effects, increases antigen presentation and lysosomal activity of macrophages, and promotes the cytotoxic effect of NK cells [10]. [171] reported that an aqueous extract of Hydrastis canadensis (1.86 g/kg p.o.) Academic information from the last five decades that describes the ethnobotanical, pharmacological, and chemical characterization of medicinal plants used as immunostimulants was gathered. Scientific studies reporting the combination of plant extracts were excluded. Explore free edible plants in your backyard and beyond. A methanol extract of R. tetraphylla leaves (1000 mg/kg p.o.) A total of 12 compounds isolated from medicinal plants used as immunostimulants have been tested using in vitro (11 compounds) and in vivo (2 compounds) assays. The same pattern was also shown in methanol extracts of leaves of Amaranthus spinosus [129], and Rauvolfia tetraphylla [130], chloroform-methanol extract of Cnidoscolus chayamansa leaves [131], aqueous extract of R. humilis fruits [132], a chloroform fraction from an ethanol extract of Tagetes erecta flowers [133], aqueous extract of Karwinskia humboldtiana seeds [134], and hydroalcoholic extract of Senna occidentalis aerial parts [135], as well as lutein and lutein ester, obtained from Tagetes erecta [136], and ethanol extract of Jatropha gossypiifolia aerial parts [137], and aqueous extract of Caladium bicolor [138]. Sanguinarine, an alkaloid isolated from Sanguinaria canadensis, was toxic at 29 mg/kg i.v. In addition, in most of the cases, the plants are not taxonomically identified [36]. This might be due to (a) the lack of established methodologies for their quantitation, (b) the quantity of the obtained compound being not enough to carry out a pharmacokinetic study, and (c) many plants extracts not being chemically characterized, and there is no main metabolite for its quantification using HPLC. Medicinal Plants from Mexico, Central America, and the Caribbean Used as Immunostimulants. Activated macrophages defend the host by phagocytosis, releasing the enzyme lysosomal acid phosphatase, and through the synthesis and release of nitrous oxide (NO) and hydrogen peroxide (H2O2) [5, 6]. Download for offline reading, highlight, bookmark or take notes while you read Medicinal Plants of North America… Some of the in vitro and in vivo tests used to evaluate the immunostimulatory effects of plant extracts and compounds include the following: (a) proliferation of splenocytes, macrophages, and lymphocytes, (b) phagocytosis, (c) pinocytosis, (d) production of NO and/or H2O2, (e) NK cell activity, (f) release of IFN-γ, IL-2, IL-6, and other interleukins, and (g) lysosomal enzyme activity. For instance, the clinical picture of intoxication with Karwinskia humboldtiana might be confused with poliomyelitis [190]. . Some medicinal plants might trigger undesirable side effects for human health because of (a) pharmacodynamic interaction with prescribed drugs, (b) intrinsic effects, (c) pharmacokinetic interaction with prescribed drugs, and (d) the presence of contaminants and/or pathogenic microorganisms. This information will be useful for developing preclinical and clinical studies with the plants cited in this review. 4.7 out of 5 stars 1,839.

Some aspects that influence the toxicity of medicinal plants reported in this study are: (a) time of exposure, (b) misidentification of medicinal plants, and (c) adulteration of medicinal plants. In a recent study we aimed to determine which herbal remedies are traditionally and currently used to manage diabetes in Central America, and to what extent scientific evidence supports their local use. Medicinal plants native to the flora of Central America. The results showed that children accounted for 93.3% of cases of exposure, which were accidental (98.9% of cases) and by ingestion (94.5% of cases). In addition, many medicinal plants require scientific evidence for their medicinal use, particularly those that are sold as food supplements. Innate immunity consists of cells such as lymphocytes, macrophages, and natural killer (NK) cells, which are the first line of host defence [2, 3]. Results of the IVDK,”, J. G. Marks Jr., D. V.

The leaves of a variety of medicinal plants can stop the growth of breast, cervical, colon, leukemia, liver, ovarian, and uterine cancer, a new study shows. An aqueous extract of Larrea divaricata aerial parts (0.5–200 mg/kg i.p.) Medicinal plants with pharmacological studies of their immunostimulatory properties were subclassified into four groups: (a) plant extracts that have been evaluated for in vitro effects, (b) plant extracts with documented in vivo effects, (c) active compounds tested using in vitro studies, and (d) active compounds that have been assayed in animal models. Treatment with plant extracts in short-term studies have effects on biochemical and hematological parameters, as well as the levels of the hepatic enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP). Medicinal plants used as immunostimulants are also used for the treatment of diarrhea (23%), cough (18%), and inflammation (18%). the Caribbean Used as Immunostimulants. It is found only in the central sierra of Peru at Medicinal herbs of Latin America D. Turner-Lloveras 4 an elevation above 13000 feet. Ohio is an incredible repository of medicinal plants and living history museums. This clearly indicates that the consumption of medicinal plants is a current topic of interest. The ethyl acetate fraction of Solanum nigrescens aerial parts [77], the ethanol extract of Ambrosia peruviana whole plant [78], the aqueous extract of Jatropha gossypifolia aerial parts [79], the methanol extract of Jatropha dioica leaves [80], the aqueous extract of Cnidoscolus urens whole plant [79], the ethanol extract of Crescentia cujete fruits [81], the aqueous extract of Enterolobium cyclocarpum bark [82], and the ethanol extract of Cordia dentata leaves and their fractions [83]. https://openknowledge.worldbank.org/handle/10986/10730?show=full [179] gathered information about Euphorbia pulcherrima exposure during an 8-year period in the United States of America. Before modern medicine developed laboratory drugs, our ancestors all over the world used herbs and weeds for health. in mice, [143], whereas capsaicin, the main active principle of Capsicum annum, had an LD50 = 190 mg/kg p.o.
