Yes. Miracle berries have been used for thousands of years in their native country without any reports of negative effects. More recently, miracle fruit have been eaten by many people in several countries without any adverse reactions or allergic effects.
Although the berry itself is not sweet, it 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 changes in taste - in particular, bitter and sour foods (such as lemons) taste sweet.
The miracle fruit's effect lasts up to two hours but the duration depends on the amount consumed.
The Miracle Fruit plant, sometimes known as the Miracule Berry, (Synsepalum dulcificum) is a plant first documented by an explorer named Des Marchais during a 1725 excursion to its native tropical West Africa. Our miracle fruit are grown and picked in Ghana before we freeze dry them to preserve the miraculin.
The plant has deep green, elongated leaves which grow in a spire-like habit. Its flowers are small and white and the fruit are ellisoidal. They are about 2-3cm long, deep red and contain a single seed.
