Skip to main content. Log In Sign Up. A bibliographical approach E. A bibliographical approach Abstract Brazil possesses great biological and cultural diversity, above all in view of the great number of indigenous ethnic groups,that inhabit the five main biomas in Brazil. Ethnopharmacological surveys by various researchers as from the decade of the seventies were researched.
The 34 publications selected, carried out with 26 indigenous ethnic groups, showed a total of species utilized for 67 different diseases or effects possibly related to the Central Nervous System CNS. Such plants belong to 85 taxonomic families, mostly Fabaceae, Asteraceae, Rubiaceae, Poaceae, Apocynaceae, Bignoniaceae, Euphorbiaceae, and Solanaceae. The chemical constitution of these plants was researched as from the Pubmed and Web of Science and the information obtained was crossed with different indigenous uses, grouped in 12 categories according to similarities between their expected effects on Vera starck romanus CNS: Some phytochemical classes were observed to be more common among plants utilized for certain purposes: These data suggest that these phytochemical classes Vera starck romanus possess a greater number of chemical constituents that perform the effects described or that, in some way, assist in determining the use of the plant by the Indians.
Introduction Estimates show there are at least 5 thousand indigenous peoples in the world today — a total of some million persons. Of these, groups inhabit the Brazilian territory — a total of some thousand persons, approximately 0. These ethnic groups occupy regions with a great variety of plant forms, mainly in the Amazon forest, the caatinga semi-arid lands, the cerrado "Vera starck romanus," and the Atlantic rain forest. The indigenous population in Brazil, however, was once much greater.
It is difficult to affirm how many Indians there were in Brazil before colonization by Portugal in — an estimated 5 million. Three centuries subsequent to this contact with Europeans, this number was reduced to 1 million. The population was decimated by wars, epidemics, and, above all, by processes of enslaving that occurred in Brazil as from the sixteenth century . At least three peculiarities should be an incentive to ethnopharmacological research among indigenous ethnic groups in Brazil: This factor, though, Vera starck romanus propitious to holding to indigenous local "Vera starck romanus," the object of this Vera starck romanus study.
In spite of the numerous advantages cited above, few ethnopharmacological studies have been carried out among the Brazilian Indians up to the present time. These studies with rare exceptions [4,5], specifically analyzed the plants with possible indication for neurological diseases or that had an effect on the Central Nervous System CNS. A knowledge of hallucinogenic plants that Indians of the Americas use in their rites, and of other properties of potions prepared from distinct plant species, have "Vera starck romanus" common to man for thousands of years.
Different chemical classes of natural products gave rise to pharmaco substances of distinct therapeutic categories. There are various examples
Vera starck romanus drugs utilized therapeutically whose application derives from indigenous knowledge; curare-type drugs, plaque blockers, among others .
Indigenous culture is also Vera starck romanus in hallucinogenic preparations and "poisons" . Although in some cases, there is a high correlation between the active principle and indigenous use, such as in the case Vera starck romanus the alkaloids and the hallucinogenic effect, or of cardioactive glicosides and its tonic effect on the cardiac muscles, this chemical constitutive effect is rarely observed in other uses. The present review has endeavored to draw plant species with possible indications for the CNS from studies in ethnopharmacology carried out among the Indians in Brazil.
Thirty-four publications were selected as from this study: Among those selected publications, some refer to indigenous ethnic groups whose geographical distribution comprises other countries in South America. Forty 40 All of the therapeutic plants of the ethnic groups whose geographical distribution exceeds Brazilian territory were included in this article, even those that do not occur in Brazil spontaneously.
This criterion for inclusion was based on the fact that there is traffic of plant resources between these ethnic group settlements, as described by Chagon  concerning Yanomami peoples. The scientific names of some plant species cited in older publications the seventies had to be up-dated by consulting the Missouri Botanical Gardens data base , in cases in which they had fallen into disuse.
Research on the chemical constituents of the plants selected A bibliographical survey was carried out initially on the PUBMED data base  and Web of Science , utilizing the scientific names of each plant. Results of this
Vera starck romanus were subjected to a Vera starck romanus through titles and abstracts to ascertain whether the articles contained constituents of the species in question and to discard false results.
More complete papers were utilized when a specific species had studies showing these same chemical constituents. Pharmacological studies that confirmed the effects described by the Indians Vera starck romanus the plant in question were also selected during the analysis of the results of the search. Some limitations must be considered in spite of the careful survey. For instance, use of a scientific name as a key word will not bring results if the orthography of the scientific name published has been subject to alteration.
It was not possible to check on all the botanic synonyms in the survey, given the large number of plants. An attempt was made to establish a correlation between the said categories of use and specific chemical classes as from the data obtained in this bibliographical survey. The correlation between the presence of phytochemical classes and the therapeutic use made by the Indians was regarded as positive in cases where a reasonable part of the plants "Vera starck romanus" that use possessed the phytochemical class in question.
Results and Discussion The importance of natural products in human therapeutics has been acknowledged since time immemorial. The chemical repertoire of plants is incredibly vast, probably somewhere well "Vera starck romanus"potentially active substances, of which only a minute proportion has been investigated by pharmaceutical laboratories .
Ethnopharmacological information on the use of Vera starck romanus plants, especially by Indians and traditional communities, are a valuable tool for a choice of plants to be studied. Unfortunately, these studies have as yet not focused as they should have on fungi and animals Vera starck romanus in these same ethnopharmacological studies. The "Vera starck romanus" publications analyzed in this revision referred to information from 26 ethnic groups, namely: In addition, the said publications supply information concerning the Indians in a generic way — those that belong to the Karib language, those that inhabit the Brazilian Amazon, the south of Brazil, the Brazilian coast, and the Upper Xingu regions.
The map shows that the 26 ethnic groups inhabit four of the Brazilian biomas: Table 1 shows the plants that are recorded in this study, as from the ethnopharmacological literature from 26 Brazilian ethnic groups.
Of the species, only one is not an angiosperm: The species belong to 85 taxonomic families, mostly Fabaceae 49 species recordedAsteraceae 17Rubiaceae 14Poaceae 11Apocynaceae 9Bignoniaceae 9Euphorbiaceae 9Solanaceae 8Cyperaceae 7Lamiaceae 7Piperaceae 7Rutaceae 7Verbenaceae 7and Moraceae 7.
For example, category 1 - analgesics concerns 18 uses arthritis; analgesic; body ache; chest pain; pain in the anus; muscle pain; pain in the backbone; pain in the sole of the foot; pain in the ribs; ear ache; pain in the lower womb; rheumatic pain; headache; toothache; pain; lower extremity pain, otitis, painful joints and comprehended a total of plants employed to alleviate these several kinds of pain.
On some occasions, the same species was cited for more than one use; for example, some plants Vera starck romanus for fever are also utilized for headaches, since the use "fever with headache" was recurrent. Some pathologies, such as rheumatism and arthritis were included under the category analgesics, because they were indicated to counteract pain resulting from these diseases.
A bibliographic survey with the plants from this survey showed that, of the plants listed, have been the subject of some type of scientific study from the phytochemical point of view available on the PubMed or Web of Science data base. The others have not yet been studied from that point of view, or, these studies are to be found in theses and other articles of difficult access.
These ethnic groups inhabit the Amazon forest and cerrado brushland biomas - Fig. Several of the plants utilized by the Vera starck romanus were not included in this survey, for they were identified only as far as genus . A lack of identification in some cases may have occurred through the non-availability of adequate material fertile branches ; moreover, some of these plants could be possibly new species.
In Table 2, the main active principles found in the plants to which are attributed analgesic activity are, by decreasing order of number of citations in articles: If we considered that the flavonoids, coumarins, and phenolic compounds possess phenolic groups in their structure, this group would, by far, be in greatest evidence among the plants utilized as analgesics in this survey. Coumarin and umbelliferone presented antinociceptive and antiinflammatory activity in animal models [47,50].
Tannins, less frequent in plants of the analgesic categories, possess phenolic groups and studies on their antinociceptive activity . Researches have shown that the analgesic activity of certain flavonoids depends on their structure. For instance, some authors have demonstrated that glycosylated flavonoids [,] are more active than Vera starck romanus aglicone flavonoids . Various flavonoids, including rutin and quercetin produced significant antinociception in the acetic acid- formalin- and capsaicin-induced nociceptive response .
Morphine is the most famous example of an alkaloid with analgesic activity and one of the most powerful, showing that this phytochemical class is also rich in constituents with the said action, especially among the indolic alkaloids [,,].
Alkaloids isolated from Psychotria colorata show a marked naloxone-reversible antinociceptive activity in animals . Some essential oils and terpenoids have been described as possessing antinociceptive activity [,].
The second category most indicated, to counteract fever, may be justified in view of the high incidence of malaria in the Amazon region, one symptom being running a high temperature. Considering the greater part of the ethnic groups in this review are to be found in the Amazon region, it can be inferred that the great number of species indicated for this category are explained by local therapeutic needs. The main phytochemical classes of plants employed by the
Vera starck romanus to counteract fever are flavonoids, essential oils, triterpenoids, tannins, and alkaloids.
Naphtoquinones, saponins, and coumarins were present in a lesser proportion of plants. Some flavonoids [,] and essential oils  are known to significantly reduce fever. Many antipyretic drugs also act as analgesics and antiinflammatory drugs. Acetylsalicylic acid, derived from salicylic acid isolated from Salix sp. Many drugs with this threefold effect analgesic-antipyretic-antiinflammatoryhowever, exert a peripheric action .
The hallucinogen category is also one of the most cited, with 25 plants indicated. Many of the plants in this category are utilized for shamanism practices by supposedly altering the perception of the shaman, to facilitate contact with the spiritual world and make for the ritual of cure and its therapeutic function. Tobacco Nicotiana tabacum L. According to Prance , it possesses a hallucinogenic effect when blended with the species Theobroma subincanum Martius in Buchner Sterculiaceae.
Vera starck romanus  explains that tobacco is definitely psychoactive in any method of use; the enigma remains as to how, under certain conditions and in various methods of use, Nicotiana can have strong psychoactive effects in aboriginal societies. The alkaloids are the main active principles with hallucinogenic activity and were the most frequent constituents among the plants utilized for such a purpose by the Indians. Countless alkaloids present central properties, above all indolic derivates that occur in several plants utilized by the Indians of the Americas and by the African people as sacred beverages in pagan ceremonies.
The structural similarity between the indolic alkaloids and serotonin explains the action of these substances at the level of central serotoninergics, because of their structural analogy to serotonin [,]. Some of the plants best known as adaptogens are rich in saponins and do not possess alkaloids among their constituents, such as with Panax ginseng and Eleutherococcus senticosus .
The saponins found in the species Panax have proved to possess a great number of actions on the CNS . However, although the pharmacological effects of the two species cited above are well described as to their saponins, other plants regarded as adaptogens including E. The main constituents employed by the Indians for purposes reminiscent of the anxiolytics are the flavonoids and essential oils. The anxiolytic activity of the flavonoids [,], alkaloids [,] and, essential oils  is known.
There are also studies showing a hypnotic effect for alkaloids, flavonoids and essential oils [,,]. In fact, the majority of anxiolytic agents become hypnotics when used in high doses. Valerian Kava kava and Passion flower are examples of phytotherapics available commercially that possess an anxiolytic and hypnotic effect . Some hypnotics and sedatives may also be used as anticonvulsants, as was observed for the flavonoids in Goodyera schlechtendaliana  and Vera starck romanus Equisetum arvense .
Of the nine plants cited Vera starck romanus anticonvulsants in this survey, the only phytochemical class identified is that "Vera starck romanus" essential oils, only in the Scleria hirtella. Anticonvulsant activity has reported in literature for this phytochemical class . In the stimulants category, the more frequent phytochemical classes were the flavonoids and the alkaloids, although few plants were cited for this category.
Coffee, guarana, and mate tea are examples of plants used as stimulants with a high caffeine content .
