The miracle fruit plant (Synsepalum dulcificum) is a plant first documented in 1725 during an excursion to its native West Africa. To enhance the flavor of their food in general, local tribes picked the berry from shrubs and chewed it before meals.

The berry contains an active glycoprotein called Miraculin. Miraculin gently binds to the tongue's taste buds, causing bitter and sour foods (such as lemons and limes) consumed afterwards to taste sweet. This effect lasts between ten minutes and two hours. It is not an artificial sweetener. Miracle fruit is 100% natural and has no known adverse side effects (beyond its temporary flavor-altering properties).

Miracle fruit is also called Miracle Berry, Synsepalum dulcificum, Richardella dulcifica, Frutto dei miracoli, Frutto Miracoloso, Fruta maravillosa, Fruto milagro, Fruta de milagro, Frutamilagrosa, Cudowny owoc, Sideroxylon dulcificum, Mirakelfrukten, Mirakelfrukt, Mirakelbær, Mirakelbaer, Wunderbeere and Mirakelbes.

Miracle fruit tablets are extremely simple to use: just dissolve one tablet on your tongue (as slowly as possible) and the effect will last from 10 minutes to 2 hours. You can try different sour foods or use a sugar free recipe to prepare your favorite dessert (suitable for diabetics).

Additional information from Wiki

The miracle fruit plant ( Synsepalum dulcificum ) produces berries that, when eaten, cause sour foods (such as lemons and limes ) consumed later to taste sweet. The berry, also known as miracle, magic, miraculous or flavor berry, was first documented by explorer Chevalier des Marchais who searched for many different fruits during a 1725 excursion to its native West Africa. Marchais noticed that local tribes picked the berry from shrubs and chewed it before meals. The plant grows in bushes up to 20 feet (6.1 m) high in its native habitat, but does not usually grow higher than ten feet in cultivation, and it produces two crops per year, after the end of the rainy season. It is an evergreen plant that produces small red berries, with flowers that are white and which are produced for many months of the year. The seeds are about the size of coffee beans.

The berry contains an active glycoprotein molecule, with some trailing carbohydrate chains, called miraculin. When the fleshy part of the fruit is eaten, this molecule binds to the tongue's taste buds, causing sour foods to taste sweet. While the exact cause for this change is unknown, one hypothesis is that the effect may be caused if miraculin works by distorting the shape of sweetness receptors "so that they become responsive to acids, instead of sugar and other sweet things". This effect lasts 15-30 minutes.
