Maranta arundinacea   Arrowroot   Family: Marantaceae          
Arrowroot flour is now produced commercially mostly in St. Vincent and the Grenadines. Arrowroot was one of the earliest plants to be domesticated for food in northern South America, with evidence of exploitation or cultivation of the plant dating back to 8200 BCE. The name may come from aru-aru (meal of meals) in the language of the Caribbean Arawak people, for whom the plant was a staple. It has also been suggested that the name comes from arrowroot's use in treating poison-arrow wounds, as it draws out the poison when applied to the site of the injury.
Arrowroot is a starch obtained from the rhizomes of several tropical plants, traditionally Maranta arundinacea, but also Florida arrowroot from Zamia integrifolia, and tapioca from cassava, which is often labelled as arrowroot.
PART USED- Rhizome- producing starch
ACTIONS
1. Demulcent.[1]
2. Nutritive especially for infants and convalescence.[1]
PREPARATIONS
Usually prepared by boiling in sufficient water to make a thin gruel, which may be flavoured if required.[1]
CONSTITUENTS: 25-27% neutral starch. The lack of gluten in arrowroot flour makes it useful as a replacement for wheat flour in some baking uses.
   

DESCRIPTION- Arrowroot is a perennial plant growing to a height of 0.3-1.5 m. Its leaves are lanceolate. The edible part of the plant is the rhizome. Twin clusters of small white flowers bloom about 90 days after planting. The plant rarely produces seed and reproduction is typically by planting part of a rhizome with a bud. Rhizomes are ready for harvesting 10–12 months after planting as leaves of the plant begin to wilt and die. The rhizomes are fleshy, cylindical, and grow from 20 centimetres to 45 centimetres long.
