Kudzu is a leafy vine. Its scientific name is Pueraria montana. It was introduced in the U.S. from Japan and China in the decade of 1930 to prevent soil erosion. As it doesn't have predators, it grows and spreads easily in the country. It is woody and it has approximately 60 feet, growing in each season. Its leaves are large and has three broad leaflets, with hairy margins. The flowers are purple and the seed pots are flat and hairy. Kudzu has been studied to understand its many possible benefits to human health, as it is traditionaly used in its place of origin to treat menopausal symptoms, alcoholism, diabetes, fever, among other conditions. It became an invasive species due to the lack of predator, causing harm to many environments where it has spreaded.
