However, Turkish bay leaves are the most commonly used type of the ancient tree,  Laurus nobilis.

It seems that various references to the laurel species of this aromatic plant may cause some confusion regarding the true bay leaf, but to be a true bay leaf it must have come from the Laurus nobilis tree. It can also be called bay laurel or sweet bay.

The tree is an evergreen tree of the Lauraceae family, native to the Mediterranean. The baby leaf is delicately fragrant with a bitter taste and contains about 2 percent essential oil.

It is more common to use the dry version of the whole leaf when cooking, then remove the leaf from the plate before serving.

The bay leaf dates back to ancient times when laurel wreaths were made to crown victorious athletes in ancient Greece, which inspired the famous crown for winners of the Boston Marathon and the Olympic Games.


In addition, it was Nike, also known as Victoria, and the origin of the name of the well-known Nike sneaker, who led the way of the laurel wreath to adorn the heads of athletes around the world.

Representing the goddess of strength, speed, victory, glory, and fame, Nike flew across the battlefields rewarding the winners with the now-famous wreath of laurel leaves (laurel leaves).

Due to its menthol-like fragrance, it was called Baywood pepperwood by early European settlers.

The Salinan Indians created a  poultice to help those suffering from seizures by combining bay leaves with cinnamon, nutmeg, and olive oil, and some tribes placed a single leaf in the nostril to cure headaches.

It was even used to attract deer by some hunters. And let’s not forget the fun of the Karok Indian children throwing the leaves into the fire to make a firecracker sound.
