Cnidoscolus is a genus of flowering plants in the Euphorbiaceae family, commonly known as the cnidoscolus or spurge nettle. This genus comprises approximately 45 species of perennial herbaceous plants native to tropical and subtropical regions of the Americas. The name "cnidoscolus" is derived from the Greek words "knídos," meaning nettle, and "skólos," meaning thorn, referring to the plant's thorny nature.
Cnidoscolus species typically possess erect or creeping stems that can vary in height, shape, and texture depending on the specific species. They are characterized by their alternate, lobed or palmately compound leaves, which often have toothed or serrated margins. Some species exhibit the presence of stinging hairs or trichomes that can cause irritation or a burning sensation upon contact with the skin, reminiscent of nettle plants.
These plants produce small, inconspicuous flowers typically arranged in inflorescences, most commonly in clusters or spikes. The flowers are usually unisexual, but some species may be bisexual, while others have separate male and female plants. Fruits are usually three-lobed capsules containing one seed. Cnidoscolus species are often found in diverse habitats, including dry forests, woodland areas, or disturbed sites.
Some species within the cnidoscolus genus have cultural importance and are used in traditional medicine. Leaves, stems, or roots of certain species are utilized to treat various ailments such as skin conditions, wounds, or gastrointestinal disorders. Additionally, certain Cnidoscolus species have edible leaves that are used as a vegetable in local cuisine, especially in Mexico and other Latin American countries.
