Fennel Seeds
Foeniculum vulgare, or as it's commonly called Fennel, is a medicinal and culinary plant from the Apiaceae family. This medicinal spice originated in the Mediterranean; however, it is now cultivated around the world. The fennel plant thrives in tropical and temperate regions, growing up to 2 metres in height. This medicinal spice can survive in a variety of soil types, such as sandy, loam and clay, as long as there is proper drainage.


The fennel plant is drought-tolerant thanks to its long, deep taproot. It has feathery, dissected leaves with yellow flowers. Fennel seeds are small, oblong-shaped and pale grey-green in colour. They are highly aromatic and offer a slightly spicy, warm and sweet flavour. 




How Fennel Seeds are Used in Traditional Medicine
Now, let's take a look at how fennel seeds are used in traditional medicine. Chewing dry-roasted fennel seeds after a meal stimulates salivary flow, helps prevent bloating and freshens breath.

Besides that, consuming fennel seeds can help flush out toxins from the body. In addition, consuming fennel seeds can ease menstrual cramps and pain associated with hernias. Furthermore, this medicinal spice can also help promote the production of breast milk in nursing mothers.
