Which of these countries was known as the Pepper, or Grain, Coast by European traders until the 19th century?

Question

In the 19th century in Europe, cubebs, known as Piper cubeba, tailed pepper, or Java pepper, were thought to be possibly a useful medicine in the treatment of what?

Answer 1

Liberia
Pepper was also known as "the grain of paradise". In the 19th century the USA moved to settle free-born blacks and freed slaves in Africa, the "Pepper Coast" being one of the nearest points (and the least expensive to reach), and it acquired the name of Liberia to reflect this.
