Miracle Berry (Synsepalumdulcificum), is a plant native to West Africa that has been used for centuries by local tribes to sweeten generally acidic diets (sour foods and drinks). Miracle berries are well known throughout Ghana by various local names including: Asaa or Asawa (Akan); Taami (Ga) and Ledidi (Ewe).
The berry is treasured not for its own taste, but for the fruit's unique effect on the taste buds. By eating the fruit and swirling the pulp around their mouths, they discovered that their taste perceptions were temporarily modified, changing their normally sour foods to taste sweet. Apart from the berrys taste modifying effect on the tongue, the miracle berry fruits and its products are now known to be a natural sweetener, rich in vitamins and antioxidants and have no calories.
