It is commonly known as rattlebox or sun hemp and includes over 500 species of annual or perennial herbs, shrubs, or even small trees. The name "crotalaria" is derived from the Greek words for "rattle," in reference to the sound produced when the seeds of some species shake inside their pods.
Crotalaria plants are native to various regions across the globe, including tropical and subtropical areas of Africa, America, Asia, and Australia. They are characterized by simple alternate leaves and showy flowers that range in color from yellow or orange to purplish-blue. The flowers are typically pea-shaped, and their petals may be fused or separated.

This makes them valuable for crop rotation and as green manure to enrich the soil. Their seeds are often toxic and contain pyrrolizidine alkaloids, which can be harmful to livestock if consumed in large amounts.
In the realm of medicine, certain species of Crotalaria have been used in traditional remedies to treat various ailments, although caution should be exercised due to their potential toxicity. Additionally, Crotalaria species have been studied for their potential as a source of secondary metabolites with pharmacological properties.
