“…Our resuits and those of others (Farnsworth, 1984a(Farnsworth, , 1984bSchultes, 1986;Cox et al, 1989;Balick, 1990), show that screening of the ethnobotanical lore of indigenous people provides a rapid and effective means of examining a flora for bioactive compounds. We found that more than 70% of the plant species used by the Garifuna of eastern Nicaragua as medicinals contained alkaloids or glycosides.…”

“…Schultes (1986) suggests that the most important drugs of the past 50 years or so were first isolated from plants used ethnomedically. In fact, 74% of the 119 biologically active plantderived compounds at present used worldwide were discovered as a result of research on species first identified in ethnobotanical surveys (Farnsworth and Soejarto, 1985;Farnsworth, 1988).…”

As part of a larger study of the plants used by the Garifuna of eastern Nicaragua, the 229 species representing 177 genera and 72 families used for medicinal purposes were assayed for the presence of bioactive compounds. A review of the literature for alkaloids and glycosides showed that 113 species contained at least one of these bioactive compounds. The remaining 116 species not previously cited were tested for alkaloids with Dragendorff's reagent; 51 contained alkaloids. The combined results show that 72% of the species the Garifuna use medicinally have at least one alkaloid or glycoside. Tests to explore pharmacological activity of compounds from selected species represent the next step to determining efficacy and application of these medicinals.

“…A long and intimate association with their floras has enabled indigenous peoples, through trial and error, to create systems of effective traditional medicine. With the advent of modern education and cultural Westernization, this empirically acquired knowledge is being lost, especially amongst the younger generations (Schultes, 1986(Schultes, , 1989. Since it is generally the older generation that holds much of the traditional knowledge, which is passed on orally, it is at risk of disappearing in the near future.…”

The study reported in this paper examined the use of plants as medicines by people on the island of SBo Tome (Gulf of Guinea). A description of the uses and preparation of the 53 most commonly used plants was noted, the collected plant material was subsequently identified at the Royal Botanic Gardens, Kew. The source of the majority of plants was domestic gardens and to a lesser extent disturbed forest close to settlements. The low human use of natural resources within the primary and advanced secondary forest areas has positive implications for the proposed conservation policies, since the protection of these areas would create little conflict with human use of the natural resources within these vegetation types. Several recommendations are made on how the modern medical system in Sao Tome might be improved by integrating into it traditional medicine.

“…The ethnopharmacology was originally defined as a science that sought to understand the universe of natural resources (plants, animals and minerals) as drugs used in the view of human groups (Schultes, 1988). However, over time this discipline has evolved and is defined by the INTERNATIONAL SOCIETY FOR ETHNOPHARMACOLOGY as: 481 (Voeks, 2009); from Africa to Brazil (Carney & Voeks, 2003); from Suriname to the Netherlands (van Andel & Westers, 2010); from Colombia to London (Ceuterick et al, 2008); from Germany to eastern Italy (Pieroni et al, 2004); from Albania to southern Italy (Pieroni et al, 2002a(Pieroni et al, , 2002b; and from Europe and Africa to eastern Cuba (Cano & Volpato, 2004;.…”
