Fennel

Fennel’s superpower is its ability to soothe the digestive system, acting as an antispasmodic, carminative, and digestive tonic, while also offering respiratory and hormonal support through its phytoestrogenic properties.

Uses

Fennel has been used since ancient times as both a culinary herb and a medicinal plant. In traditional European herbalism, it was employed to relieve digestive discomfort, such as gas, bloating, and indigestion. Fennel seeds were also chewed after meals to freshen the breath and aid digestion. In Ayurveda and TCM, fennel was used to balance digestion, clear mucus from the lungs, and support milk production in lactating women.

Current Uses:
Today, fennel remains a popular remedy for:

Digestive support, especially for bloating, gas, and indigestion
Acting as an antispasmodic to relieve colic and intestinal cramps
Respiratory health, helping to clear phlegm and soothe coughs
Supporting hormonal balance, particularly for women, due to its mild phytoestrogenic properties
Breast milk production (galactagogue) for nursing mothers

Botanical Description

Growth Habit:
Foeniculum vulgare is a tall, perennial herb that can grow up to 2 meters (6 feet) in height. It has a hollow, grooved stem and produces delicate, feathery leaves that are finely divided.

Leaves:
The leaves are fern-like, feathery, and finely dissected into thread-like segments. The leaves are highly aromatic and can be up to 40 cm long.

Flowers:
Fennel produces umbrella-shaped clusters of small yellow flowers called umbels, which bloom from late summer to early autumn. Each umbel can have up to 50 small flowers that eventually produce seeds.

Fruit/Seeds:
The fruit, commonly referred to as fennel seed, is small, oval, and ribbed. The seeds are green when fresh but turn brown as they dry. They are highly aromatic and are often used in cooking and medicine.

Roots:
The plant has a taproot, though it is the aerial parts (leaves, seeds, and flowers) that are most commonly harvested for medicinal and culinary purposes.

Habitat:
Fennel thrives in Mediterranean climates but has been widely naturalized throughout Europe, North America, and Australia. It prefers well-drained soils and full sun, often found growing wild in coastal areas and along roadsides.

Parts Used

Seed

Harvest

Seeds:
Fennel seeds are the most commonly harvested part of the plant. They are typically harvested in late summer or early autumn when the flower heads begin to dry and the seeds turn from green to brown. The best time to harvest fennel seeds is on a dry, sunny day when the seeds are fully mature but have not yet fallen from the flower head.

Method: Cut the flower heads with a few inches of stem attached. Place them upside down in a paper bag to allow the seeds to fall out as they dry. After drying, the seeds can be separated from the stems by gently rubbing the flower heads.

Leaves:
The leaves can be harvested throughout the growing season, from spring to early summer, while they are still tender and vibrant. They can be used fresh in cooking or dried for later use in teas and infusions.

Method: Use clean scissors or garden shears to clip the leaves, leaving enough growth for the plant to continue thriving.

Bulbs (if growing Florence fennel):
The bulbous base of fennel (often referred to as Florence fennel or Finocchio) is typically harvested in late summer or early fall when it reaches a size of about 8-10 cm in diameter. The bulbs should be firm and plump when harvested for culinary use.

Method: Cut the bulb at the base, just above the root system. The bulbs can be eaten raw, roasted, or added to dishes.

Preparations

Tea/Infusion: Fennel seeds can be steeped in hot water to create a digestive tea for bloating, gas, and indigestion. It can also be used to ease respiratory discomfort and phlegm.

Tincture: Fennel seed tinctures are commonly used for digestive issues and to support hormonal balance.

Essential Oil: Used in aromatherapy for respiratory support, digestive health, and emotional grounding.
