Allspice takes its name from its aroma, which smells like a combination of spices, especially cinnamon, cloves, ginger and nutmeg. In much of the world, allspice is called pimento because the Spanish mistook the fruit for black pepper, which the Spanish called pimienta. Allspice is the only spice that is grown exclusively in the Western Hemisphere. There are plantations in Mexico and parts of Central America but the finest allspice comes from Jamaica where the climate and soil are best suited to producing the aromatic berries. It is a digestive and carminative. The oil is classed as rubefacient, meaning that it irritates the skin and expands the blood vessels, increasing the flow of blood to make the skin feel warmer. The tannins in allspice provide a mild anesthetic that, with its warming effect, make it a popular home remedy for arthritis and sore muscles, used either as a poultice or in hot baths.
