What is Fennel Tea?

Discovered thousands of years ago, fennel has marked its importance as a medicinal herb in Asian, European, Middle Eastern and Western sub-continents.

Fennel Tea health benefits

Besides its use in cooking, fennel also aids in a host of medical conditions like bloating, acidity, and flatulence.

Fennel tea is prepared from ground mature or crushed fennel seeds. These seeds are loaded with essential oil compounds like estragole, fenchone, and anethole.

These compounds are excellent in antibacterial, antispasmodic and anti-inflammatory properties. Just by boiling the fennel seeds in water, the oils blend well, and you get a clear broth that is extremely beneficial for your body.
