Sidr leaves, commonly found in Morocco, come from the Sidr tree (Ziziphus spina-christi), which is a hardy, drought-resistant shrub or small tree. The leaves are green with a smooth, glossy texture and have a distinctive shape—oval or elliptical, with a pointed tip and often a slight curve. They are relatively small, ranging from 2 to 5 cm in length. These leaves are known for their medicinal properties and are often used in Moroccan traditional medicine for their antibacterial, anti-inflammatory, and antioxidant benefits.

Sidr leaves are commonly used in a variety of ways, such as for infusions or as part of cosmetic treatments. The tree itself is highly valued for its strong wood and its fruit, known for its edible, sweet-tasting qualities, often used in herbal medicine and beauty products.
