The canavalia plants typically have large, lush foliage and produce beautiful flowers that range in color from white to purple. These flowers give way to elongated pods that contain bean-like seeds. The seeds are often large, flat, and have a glossy, dark brown coat. They are rich in proteins, starch, and various minerals, making them a valuable source of food for both humans and animals.
In addition to their nutrient-rich seeds, canavalia plants also offer other benefits.

Because of this, they are often grown as cover crops or green manure to improve the soil quality in agricultural practices.
Canavalia plants have also found use in traditional medicine and herbal remedies. Their seeds have been used in traditional Ayurvedic medicine to treat various ailments, including liver disorders and cardiovascular diseases.
Overall, canavalia is a diverse genus of tropical plants that provide food, environmental benefits, and medicinal properties.
The word "canavalia" is derived from the genus name Canavalia, which is a group of flowering plants in the legume family, Fabaceae. The origin of the word Canavalia can be traced back to the ancient Greek language. It is believed to have been derived from the Greek word "kanabalis", which means "hemp-like" or "resembling hemp". This is likely because some species of the Canavalia plants bear similar physical characteristics to hemp plants.
