Ethnobotanical Insights into Lima Bean (Phaseolus lunatus): Exploring Its Traditional uses, Cultural Significance, and Educational Value

Abstract

Phaseolus lunatus, commonly known as the Lima bean, is a highly nutritious legume with significant ethnobotanical importance that extends far beyond its value as a food source. This review consolidates knowledge on its traditional uses, cultural significance, and educational potential. Nutritionally, Lima beans are a robust source of plant-based protein (17-40 g/100g), comparable to meat, and are rich in dietary fiber, vitamins, and minerals, offering health benefits for cardiovascular disease, diabetes, and cancer prevention. Its traditional applications are vast, encompassing ethnopharmacology for treating fever, inflammation, and wounds, and ethnoveterinary medicine as a galactagogue and general tonic for livestock, demonstrating a sophisticated, empirical understanding of its properties and safe preparation to neutralize cyanogenic glycosides. Culturally, the bean holds profound symbolic meaning, particularly in African and African Diaspora traditions, where it is used for spiritual protection in Hoodoo practices, divination, and as a symbol of resilience and cultural identity. Furthermore, the Lima bean serves as an exceptional model organism for interdisciplinary education. Its morphological traits and rapid growth cycle are ideal for teaching botany and plant physiology, while its well-defined composition provides a tangible case study for lessons in nutrition, food science, and food safety. In conclusion, the Lima bean is a vital repository of biocultural heritage, whose full appreciation underscores the deep interconnections between plants, human health, and culture.
