Water caltrop, scientifically known as Trapa natans, is an aquatic plant species that belongs to the family Trapaceae. It is characterized by its distinctive fruit, which resembles a vigorous, four-horned nut or seed pod.

It can be consumed raw, boiled, or stir-fried, and is a common ingredient in a variety of dishes, such as soups, salads, and desserts.

Additionally, water caltrop has been used medicinally in traditional practices. It is believed to possess anti-inflammatory and antioxidant properties. Various parts of the plant, including the leaves and roots, have been used to treat ailments such as diarrhea, dysentery, and skin infections.
