The clove actually isn’t a stick or piece of wood, but actually a dried and unopened flower. These flowers are originally native to the Moluccas, a chain of volcanic islands near Indonesia. Few people ever see the delicate red flowers due to the spice’s popularity.
The clove also has a history of medical use. Their essential oils have the ability to assist digestion by increasing stomach acid, relax muscles in the body, and whole cloves work as oral painkillers (pop one in your mouth next to a sore tooth).
