Smilax is a genus of climbing plants commonly known as greenbriar or catbriar. These plants are characterized by their thorny stems, heart-shaped leaves, and small, often fragrant flowers. They can be found in various habitats, including forests, wetlands, and disturbed areas, primarily in North America and tropical regions. The roots of some Smilax species are edible and have been used in traditional medicine for their anti-inflammatory and diuretic properties. Additionally, the young shoots and leaves can be consumed as vegetables. However, caution is advised, as some species may have toxic properties or cause allergic reactions.
