Abstract: Datura metel, commonly known as Black Datura, occupies a significant position in traditional botanical literature owing to its striking morphology, potent bioactive profile, and longstanding medicinal associations [1], [2]. Among its various organs, the leaf represents one of the most functionally important structures, serving not only as a primary photosynthetic unit but also as a major reservoir of secondary metabolites such as tropane alkaloids, phenolics, tannins, and related phytoconstituents. Despite the frequent mention of the species in ethnomedicinal discourse, focused academic treatments devoted specifically to leaf structure, composition, and applied significance remain comparatively limited. The present paper offers a concise yet critical study of the leaves of Datura metel through botanical, phytochemical, therapeutic, and toxicological perspectives [3], [4].

    The study aims to examine the taxonomic identity and morphological characteristics of the leaves, evaluate their medicinal relevance in traditional systems, and assess the scientific concerns associated with their toxic nature. Special attention is given to the dual character of the plant: on one hand, its leaves have been historically employed in practices relating to respiratory discomfort, inflammatory conditions, dermal disorders, and analgesic applications; on the other hand, the presence of atropine, scopolamine, and hyoscyamine demands rigorous caution in handling and usage. This paradox between utility and toxicity makes the species an important subject of scholarly investigation.

    Available literature indicates that the leaves possess notable pharmacological potential including antimicrobial, antioxidant, anti-inflammatory, bronchodilatory, and wound-healing tendencies under controlled conditions. However, indiscriminate use, inaccurate identification, and non-standardized dosage may result in severe physiological consequences [5]. Therefore, a balanced scientific approach is necessary.

    The paper concludes that the leaves of Datura metel deserve continued interdisciplinary study in pharmacognosy, medicinal botany, and toxicology. Their traditional relevance may be strengthened through evidence-based validation, standardization protocols, and responsible therapeutic exploration [6].
