Botanical Overview
Sunhemp (Crotalaria juncea) belongs to the Fabaceae family. Limited but reliable traditional records indicate this plant has recognized medicinal applications in one or more healing traditions. The legume family (Fabaceae) includes trees, shrubs, and herbs that produce pods (legumes) and form nitrogen-fixing root nodules through symbiosis with bacteria. The flowers are typically pea-shaped with five petals. This large family provides food staples, timber, and numerous medicinal species.
General Description
It is generally considered to have originated in India. It is now widely grown in the Indian subcontinent and Brazil for its fiber, which makes it especially useful in the manufacturing of twine, rug yarn and fish nets. This plant is also used as forage for cattle and goats as they have a significant percentage of protein (34. 6%). Additionally, according to new research from the Agricultural Research Service (ARS), Sunn hemp is being looked at as a possible bio-fuel. After being put under experimental research the Sunn hemp was found to have produced 82. 4 gigajoules of energy per acre, equivalent to 620 gallons of gas. Although it is a useful plant it can be an invasive weed and has been listed as a noxious weed in some jurisdictions.
