The Creole expressions
Born in the first half of the 17th century, the Creole language is a mosaic of extraordinary richness. To the Amerindian legacies were added the dialects of the French colonists, the Blacks of West Africa and, later of the Coolies of India or China. Creole expressions, some of which have existed for centuries, have enriched the language and have fully integrated the local culture, way of life and linguistics.

Tjenbwa
The word tjenbwa comes from the phrase tiens, bois (hold, drink in english) which is said to patients when they are given medication. So from medicine, we went to magic potion and so to tjenbwa (in local Creole).
Note that the word has been francized and you will also hear the term Quimbois.
