Enquête ethnobotanique et étude botanique de bunium pachypodum p.w.ball, apiaceae تالغود))

Abstract

This thesis explores the medicinal plant Bunium pachypodum P.W. Ball., commonly known as Talghouda, whose tubers are traditionally used in Algerian folk medicine, particularly for treating thyroid disorders. This plant, belonging to the Apiaceae family, grows in Algeria and shows significant potential for phytotherapeutic applications. The study combines an ethnobotanical survey conducted with 45 herbalists in the cities of Sétif and El Eulma, and a botanical investigation performed in the pharmacognosy laboratory of Sétif. The survey revealed that the tubers, mostly used in powdered form, are primarily employed in the treatment of goiter. The botanical analysis described the general morphology of the plant, characterized by its variable height (35 to 70 cm), starch-rich tubers (1 to 6 cm in diameter), compound leaves, and umbellate inflorescences with 8 to 14 rays. Some morphological variability was observed, likely due to ecological and genetic factors. The histo-anatomical study of the tubers—conducted for the first time on this species— highlighted key structural features: a well-developed cortical zone, numerous secretory canals, parenchyma rich in starch, and a complete vascular system (xylem, phloem, and cambium). These findings contribute to a more accurate botanical identification and enhance our understanding of the plant’s biological properties. This research contributes to the preservation of traditional knowledge associated with Talghouda and provides a foundation for future pharmacological and clinical studies aiming to scientifically validate its therapeutic uses.
