What South Indian spice has been given the name "Queen of Spices"?

Put simply, the queen and king of spices, respectively, are cardamom and black pepper, both of which formed an intrinsic part of the early spice trade and, as such, have been labeled the queen and king of spices. As two of the most widely used spices, and with cardamom also the third most expensive spice in the world, this nickname has stuck and so it isn’t uncommon to see the term ‘queen of spices’ used to refer to cardamom even in the modern-day.
