Fennel seed oil is an essential oil extracted from the seeds of the fennel plant, scientifically known as Foeniculum vulgare. Fennel is a flowering herb belonging to the carrot family (Apiaceae) and is native to the Mediterranean region, although it is now cultivated in many parts of the world for its culinary and medicinal uses.

The oil is obtained through steam distillation of the crushed seeds, resulting in a highly aromatic and concentrated liquid with a sweet, spicy, and slightly licorice-like aroma.

Here are some common uses and benefits of fennel seed oil:
