Fennel is a perennial and pleasant-smelling herb with yellow flowers. It is native to the Mediterranean region but is now found throughout the world. Dried fennel seeds are often used in cooking as an anise-flavored spice. Fennel’s dried ripe seeds and oil are often used to make medicine.
Fennel is believed to relieve headaches, calm the body, promote digestion, relax intestinal muscles, fight against brain fatigue, and ail cough.
