Description: The miracle fruit plant grows as a dense shrub or small tree, usually not more than 5.5 m in height in the wild. The simple leaves are oval and tapering at the base with smooth margins and feature a waxy underside. They grow in spirelike clusters at the ends of small branches. The small white flowers give rise to red drupe fruits that are about 2–3 cm in length. Plants typically begin producing fruit after three or four years and require acidic soil. Use: Synsepalum dulcificum is grown for its mild fruits that make subsequently eaten sour foods taste sweet. Therefore, it is used for diabetes, obesity and taste disturbances. The flavour-altering mechanism of miracle fruit is due to a glycoprotein named miraculin, which was first isolated by Japanese researcher Kenzo Kurihara in 1968. Although miraculin itself is not sweet, it binds to receptors on the taste buds and causes acidic foods to be perceived as sweet. The effect typically lasts from a half hour to two hours, with the intensity declining over time. 42. Scientific name: Andira inermis (W. WRIGHT) KUNTH EX DC.
