Medicinal Plants Used by Traditional Healers in the Treatment of Gastrointestinal Disorders in Oued Souf Region (southeast of Algeria)

Abstract

This study aims to analyze indigenous knowledge of medicinal plants used by traditional healers to treat gastrointestinal disorders in the Oued Souf region. Data were collected through open-ended, semi-structured interviews. Various statistical indices, such as UV and ICF, were employed to evaluate quantitative data. The findings reveal that traditional healers utilize 47 medicinal plant species from 22 families for treating gastrointestinal disorders. Lamiaceae and Asteraceae emerge as the most dominant families, with 9 and 7 species, respectively. The most frequently used plant parts were leaves (35%), and the predominant method of preparation was infusion (55%). Among the most popular plants used by local healers were Artemisia herba alba Asso (UV = 0.85) and Juniperus communis (UV = 0.75). The study highlights the significant number and variety of medicinal plants employed by traditional healers to address digestive disorders. Consequently, this research can aid scientists in identifying plants with medicinal properties that may contribute to the development of new medications.
