Ethnobotanical Uses of Pandanaceae Species in Selected Rural Communities in the Philippines

Abstract

Pandanaceae is recognized for its diverse traditional uses in many tropical countries. In the Philippines, little has been documented regarding its use and significance in rural communities. This study explores the ethnobotanical uses of Pandanaceae species in five target areas to perceive the transfer and dispersal of traditional plant knowledge within the communities. Results suggest a good transfer and dispersal of traditional knowledge within the members of its respective communities, with females and elder informants generally displaying extensive plant knowledge. Different localities exhibit specialized uses of Pandanaceae plants. Eight species are documented, of which six are endemic species. Highest use-values (UV ≥ 1) come from Pandanus tectorius, P. luzonensis, and P. radicans, owing to their diverse ethnobotanical uses. Most medicinal Pandanaceae are used to treat genitourinary diseases, primarily urinary tract infection. Pandanus amaryllifolius, P. radicans, and Sararanga philippinensis serve as food, commonly used as rice flavoring and as different viands. The leaves of all species, except P. amaryllifolius, are sources of material for woven-products and crafts. Despite the communities’ heavy reliance on Pandanaceae species, good management and harvesting practices are being observed, allowing these economically important plants to thrive abundantly in their area.
