7 Science-Based Health Benefits of Fennel Seeds

Fennel seeds have become popular in recent years because of their nutritional properties and health benefits. Fennel is a sweet-smelling herb, originally from the Mediterranean, which people have used for centuries for various natural benefits and remedies.

Although we add it to salads, sauces, and baked products, the most common way to ingest it is as a tea. This drink is also characterized by a strong aroma and a light licorice flavor. It’s relaxing and gives the body a significant amount of antioxidants.

Health Benefits of Fennel Seeds

Fennel seeds have a slightly sweet taste, similar to aniseed or licorice. They’re collected from fennel plants (Foeniculum vulgare), which grow up to around 50 inches, have feathery leaves and yellow flowers.
