Miracle fruit is an evergreen shrub that grows in West Africa. The berry, leaf, and seed oil are used as medicine. People use miracle fruit for diabetes, obesity, taste disturbances in people treated with cancer drugs, and other conditions, but there is no good scientific evidence to support these uses.If you're wondering how to consume the actual miracle fruit, just chew on the pulp of the fruit to experience its taste-modifying properties. Your sour or tart food, fruit, and drink becomes deliciously sweet! Using one miracle berry affects your sense of taste for about 30 minutes to an hour.
