Synsepalum dulcificum is a plant in the Sapotaceae family, native to tropical Africa. It is known for its berry that, when eaten, causes sour foods subsequently consumed to taste sweet. This effect is due to miraculin. 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.This so-called “Miracle Fruit” resembles a fresh cranberry and is nearly tasteless to humans. However, if a person chews on the berry and holds it on his/her tongue for a short time, it causes subsequent sour foods to taste sweet. The taste altering effect lasts approximately thirty minutes
