EXEGESIS
Zanjabīl is the Arabic term for the spice ginger. It is delicious, prevents certain ailments, and enhances flavour. Arabs were reputed for loving the flavour of zanjabīl. In fact, just as they would use kāfūr flavoured drinks to relax, they would use the zanjabīl flavoured drink to energise themselves.
