Sweet Licorice-Scented Green Herb
The herb fennel (Foeniculum vulgare) grows as a perennial plant with feathery green leaves and hollow stems, typically reaching heights of 3-5 feet. Its distinct anise-like aroma comes from anethole, a primary aromatic compound found in the plant.
Fennel has been documented in Mediterranean cooking since Roman times, where both its bulb and seeds are used in various dishes. The plant contains essential oils including fenchone, estragole, and limonene. Multiple clinical studies have shown fennel extracts can help reduce digestive discomfort and bloating due to their antispasmodic properties.
