Ethnopharmacological Study of Anti-Allergic in the Central Cikarang Region, Bekasi, West Java, Indonesia

Allergies are a problem that greatly affects the population, and hence the use of antiallergic medications is fairly widespread. However, these drugs have many adverse effects. The use of medicinal plants could be an option, but they need to be evaluated. This research aims to document and preserve the use of ethnomedicine to treat allergies by people in the Central Cikarang Region, Bekasi, West Java, Indonesia. Fieldwork was carried out from November to December 2025 using direct interviews, questionnaires and discussions. Plant species are identified based on standard taxonomic methods, flower morphological characteristics, and where possible, using samples for comparison, as well as consultation with experts and the literature. The plant types obtained were grouped into families according to the Cronquist classification system. Plant names were checked against the Plant List (www.plantlist.org) and the International Plant Name Index (www.ipni.org). This study reports that 30 plant species are commonly used by people in the Central Cikarang Region to treat allergies. Among the various plant parts used, leaves (50.0%) are most often used in making medicine, followed by rhizome (13.3%), fruit (13.3%), stem, seeds, and flower (6.7% respectively), and rind (3.3%). Meanwhile, the most frequently used preparation method was decoction (76.7%) and infusion (23.3%). The results of this research confirm that people in the Central Cikarang Region still rely heavily on medicinal plants for their health care system, especially for the treatment of allergies with the most frequently used parts of the leaves and their use in decoctions and infusions.
