Ethnobotanical characterization of edible Jatropha curcas L.

Objective. To characterize the traditional knowledge about edible Jatropha curcas L. in the municipality of Coetzala, Veracruz, Mexico. Design/ Methodology/ Approach. This research was conducted with a descriptive cross-sectional approach, through a non-probabilistic sampling for convenience. A semi-structured survey consisting of 22 questions was applied to 31 owners of family home gardens with the presence of J. curcas. The questionnaire included sociodemographic data, plant characteristics, technological aspects and traditional uses. Data were managed and stored in Microsoft™ Excel®, then analyzed using absolute and relative frequencies. Results. The J. curcas trees had an average age of 9.9 years, 2.9 m in height and 3.7 trees per home garden. Of the interviewees, 93.5% indicated these trees show resistance to pests and diseases. The main form of propagation recorded was by seed (77.4%), while vegetative propagation accounted for the other 22.6%. Gastronomic use was reported by 100% of the participants, mainly the consumption of seeds in the form of pipian and in other traditional dishes. Fruits were the most widely used plant organs, and seeds are mainly stored in nylon or paper bags. Limitations/ Implications of the study. The findings correspond to the surveyed households and describe the local knowledge in the conditions of Coetzala. Findings/ Conclusions. This edible J. curcas variety is a food and biocultural resource associated with home gardens, traditional cuisine and in situ conservation. The design of public policies for Xuta conservation, revaluation, and sustainable use is recommended.
