Traditional uses and potential of Boscia salicifolia Oliv. in addressing malnutrition in Burkina Faso

Indigenous leafy vegetables have significant potential for alleviating malnutrition in sub-Saharan Africa. However, despite their well-documented nutritional value, their consumption remains limited due to negative perceptions and lack of awareness regarding their health benefits. This study investigated the traditional uses and local perceptions of Boscia salicifolia consumption in Burkina Faso. Data were collected through semi-structured interviews with 137 respondents.

The findings revealed that B. salicifolia is mainly found on hillsides (58%) and is primarily valued for its leaves, which are used both as human food and livestock fodder. In addition,roots and bark are used in traditional medicine. Consumption patterns varied by age: young people reported occasional use (54%), whereas older adults, particularly women (39%), consumed the leaves at least three times per week, reflecting greater awareness of their nutritional benefits. Older respondents emphasized health-promoting effects such as kidney cleansing (53%) and facilitating digestion (44%). In contrast, younger respondents mainly highlighted its role in alleviating hunger (70%) and treating stomach discomfort (41%). These age-related differences reveal a significant decline in traditional knowledge across generations.

This study underscores the nutritional and cultural importance of Boscia salicifolia and the generational shifts that limit its consumption. Addressing stigma, improving awareness among younger individuals, and conducting further research on its nutritional value are essential. Targeted awareness and community-based valorization efforts could promote its dietary integration, contributing to improved nutrition and food security in sub-Saharan Africa.
