Quantitative Ethnopharmacological Prioritization of Sundanese Medicinal Plants in Cisarua, West Java

Ethnomedicinal knowledge can guide the selection of herbal candidates, but quantitative evidence from West Java is limited. This cross-sectional survey documented medicinal plant use among 31 Sundanese informants in three villages of Cisarua. Semi-structured interviews yielded 224 therapeutic use reports covering 66 taxa from 30 families, from which use-report, citation, fidelity, consensus, family-use, and Jaccard indices were calculated. Knowledge varied widely between informants (median four taxa; range 1–22). Leaves (60.3%), decoction (62.9%), and oral administration (72.8%) predominated. Plantago major L. had the highest use-report count (23), use value (0.742), and relative frequency of citation (0.516), whereas Ageratum conyzoides L. and Musa spp. showed high fidelity for lacerations (80.0% and 81.8%, respectively). Lacerations/cuts formed the largest indication category (39 reports; ICF = 0.789). Taken together, salience, specificity, and report volume identified wound-related taxa as priorities for authentication, standardized extraction, pharmacological validation, and safety assessment.
