Miracle Fruit

Miracle Fruit is native to tropical West Africa. This shrub grows up to six-meters tall, and has brown flowers with small red fruit or berries.  They are the miracle fruit or miracle berry. The locals have long used it to add sweetness to palm wine or beer that's gone sour, or to make stale acidified maize bread more palatable. The effect lasts for a few hours.
