Scotch Bonnet Pepper
The first main ingredient of jerk seasoning is Scotch bonnet chile pepper, a variety of the habanero, so named for the shape of the pepper which resembles a Scotch tam or hat. This pepper ranges in color from green to yellow to red, often mixed depending on the ripeness of the pepper. The purpose of the pepper was originally found out by the many pirates that use to plunder many of the Caribbean islands. The found that after a heavy spicy meal, that when they bit into this pepper (and I don't know how they did that), that it actually helped indigestion.
