I'm not sure why, but I have been under the impression that bergamot—an ingredient I often come across in fragrances—is a spiny flower. Indeed it is, but I did not know that the Italian and Ivory Coast-based plant also produces a pear-shaped yellow citrus fruit. It is not, however, in any way, shape or form, related to the bergamot herb.
The skin of said yellow fruit yields a delicate, yet spicy, essential oil that is found in one-third of all fragrances. It's also used to treat acne, eczema, and seborrhoea. When it's not being used for its aroma, it can be found in Earl Grey tea (it aids digestion), insect repellent, and medications that treat urinary tract infections and depression. Very versatile indeed.
