MIRACLE FRUIT PLANT

The Pokok Ajaib or Miracle Fruit Plant (Sideroxylon dulcificum/ Synsepalum dulcificum) that I planted about three years ago has finally started to bear fruit - two to be exact.
So why is it called Miracle Fruit or Miracle Berry?

Here is the explanation found in Wikipedia.

The berry is sweet, and 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 bitter and sour foods (such as lemons and limes) consumed later to taste sweet. This effect lasts between thirty minutes and two hours. It is not a sweetener, as its effects depend on what is eaten afterwards, but has been used to cause bitter medicine to taste sweet.
