Fennel, an aromatic plant native to Europe and Asia, is in the same plant family as carrots. The uses for this yellow, flowering plant range from flavoring food to repelling insects, specifically fleas. The herb may help promote lactation for breast-feeding women and may help ease digestive discomfort. While the stalk of the fennel plant is traditionally eaten as a vegetable, the seeds are crushed and used for medicinal purposes. People often make a tea or chew the seeds to help relieve gastrointestinal distress such as flatulence and infantile colic.

Younger, greener seeds from the fennel plant are better options for chewing, while older, yellow seeds are best for cooking.
