Medicinal plant knowledge and its erosion among the Mien (Yao) in northern Thailand

Ethnopharmacological field studies: a critical assessment of their conceptual basis and methods.

Ethnopharmacological notes about ancient uses of medicinal plants in Trás-os-Montes (northern of Portugal)

In this chapter the reader will have the opportunity of a brief explanation of the terms most commonly used by ethnobiologist and ethnoecologist as well as access to information about procedures for contact with the informant, theoretical and practical to check the validity and reliability of information obtained, and which the main measures to be adopted in resolving the problem of sampling.

Methods and Techniques in Ethnobiology and Ethnoecology

Ethnobotanical study of medicinal plants from the Humla district of western Nepal.

An ethnobotany study in collaboration with Q'eqchi' Maya healers of Southern Belize led to a collection of 169 medicinal plant species, belonging to 67 different families. The data show the use of a majority of species from primary or secondary semi-evergreen rainforests of Southern Belize, rather than weedy species. The medicinal uses of the plants were grouped into 17 usage categories. The frequency of use for each plant and the informant consensus factor for each usage category reveals a consensus among the healers on the use of plant species as well as on the diseases treated. These results suggest a well-defined medicinal tradition.

A consensus ethnobotany of the Q’eqchi’ Maya of Southern Belize

Ethnopharmacology of Q'eqchi' Maya antiepileptic and anxiolytic plants: effects on the GABAergic system.

Plant Use by the Q’eqchi’ Maya of Belize in Ethnopsychiatry and Neurological Pathology. Economic Botany 59(4):326–336, 2005. Neurological and mental health disorders are extremely debilitating, and sufferers in developing countries often rely on traditional practitioners for these medical needs. Few studies have focused on botanical remedies used in this context, although these offer interesting treatment alternatives. The present study investigated plant use for the treatment of neurological and mental health disorders by Q'eqchi' Maya healers of southern Belize. We found that these healers generally recognize and treat epilepsy/seizures, headache, madness, fright (susto), depression, numbness, insomnia, and stress with herbal remedies. Quantitative analyses showed that there is selection for the use of certain species and botanical families, namely for species of the Pteridophyta division and for plants from the Piperaceae family. This study denotes the importance and selectivity of plant use by Q'eqchi' healers of southern Belize for the treatment of neurological and mental conditions and points to a possible underrepresentation of these disorders in the ethnobotanical literature.

Plant Use by the Q'eqchi' Maya of Belize in Ethnopsychiatry and Neurological Pathology

Ethnopharmacological investigation of plants used to treat susto, a folk illness.

A previous study provided a general quantitative analysis of 169 collected medicinal plants used by the Q'eqchi' Maya healers of southern Belize. This paper is focused on a statistical analysis of this ethnobotanical information using the method developed by Moerman (1991). The residual values obtained from the regression analysis of the Q'eqchi' medicinal plant species versus the species listed in the checklist of the vascular plants of Belize (Balick, Nee, and Atha, 2001) placed the Piperaceae, the Rubiaceae, and the Asteraceae in the first three ranks, and the Poaceae, the Cyperaceae, and the Orchidaceae in the last three ranks. The results were compared with three northern temperate regions (Kashmir, Korea, and North America) and three southern neotropical regions (Chiapas, Ecuador, and Veracruz). The coefficients of correlation between the checklist of vascular plants of Belize and the other six floras showed, as expected, high values for regions with similar climatic type. Thus, high correl...
