Key Constituents

Essential oil (trans-anethole)[3, 10]

Trans-anethole typically makes up the great majority of the volatile oil and gives anise its characteristic liquorice aroma and much of its digestive and antimicrobial activity.

Safety, Cautions & Contraindications

Safety note[11, 12, 13, 14, 15]Caution

Generally safe when consumed in food amounts. Doses up to 20g daily considered safe for adults. May cause allergic reactions in some people. Caution advised during pregnancy and breastfeeding - stick to food amounts. Anethole can be toxic at high concentrations, particularly to the nervous system. Not enough safety data for medicinal use in children.

Safety note[11, 12, 13, 14, 15, 16]Info

Duke (2002) provides clinical evidence (score 2) for anise as an antibacterial, antiseptic, antispasmodic, and expectorant. It has demonstrated estrogenic activity and is used as a clinically supported lactagogue to promote milk production. Commission E and WHO have both approved its use for catarrh and gastrointestinal spasms. Typical dosages are 0.5–1 g crushed seed three times per day in tea, or 0.05–0.2 ml of the fruit essential oil (Duke, 2002).

Safety note[11]Caution

Traditional use only; clinical evidence is limited, so a persistent cough or digestive complaint needs medical assessment. Safety in pregnancy and breastfeeding is not established.

Safety note[2, 8]Info

Buy from a reputable source: Veronica officinalis is frequently adulterated with the related Veronica chamaedrys.

Botanical Description

Annual herb (Apiaceae), 30-60 cm tall, with an erect, downy stem. Lower leaves are rounded and toothed or shallowly lobed, while upper leaves are finely feathery and pinnately divided. Small white flowers are borne in compound umbels, followed by small, ridged, downy fruit ('aniseed') with a strong, sweet, liquorice scent.

Height: 30-60 cm
Habit: Erect, downy annual herb
Leaves: Lower leaves rounded/toothed; upper leaves finely feathery, pinnately divided
Flowers: Small, white, in compound umbels
Stem: Erect, downy
Root: Slender taproot
Fruit: Small, ridged, downy, sweetly liquorice-scented fruit ("aniseed")
Flowering Period: July-August

Low, creeping, mat-forming perennial herb with softly hairy, oval, finely toothed leaves along trailing stems that root as they spread. Small, pale lilac-blue flowers with darker veining are borne in slender upright spikes rising from the leaf axils.[8]

Height: 5-40 cm (upright flowering spikes; creeping stems low)
Habit: Low, creeping, mat-forming perennial herb
Leaves: Softly hairy, oval, finely toothed, opposite
Flowers: Small, pale lilac-blue with darker veining, in slender upright axillary spikes
Stem: Trailing, softly hairy, rooting as it spreads
Root: Fine roots along the creeping stem
Fruit: Small, flattened, heart-shaped capsule
Flowering Period: May-August

Habitat

Native to the eastern Mediterranean and south-west Asia, widely cultivated as a spice and medicinal crop in warm-temperate regions worldwide, needing a long, warm growing season and well-drained soil.

Grows on dry heath, moorland, open woodland, grassland and banks on acidic, well-drained soils; native to Europe and naturalised in North America.[8]

Harvesting

Fruit ('seed') is harvested in late summer once the umbels have dried and turned brown, then threshed and dried further.

Parts: Fruit, Seed
Season: Late summer, once umbels have dried

The flowering aerial parts are cut in summer while in flower and dried in a warm, shaded, airy place; the closely related Veronica chamaedrys is a frequent adulterant, so careful identification (or a reputable source) is important.[8]

Parts: Aerial parts (flowering herb)
Season: Summer, at flowering

Traditional Uses

Anise has a long Mediterranean and Middle Eastern tradition as a carminative digestive remedy for bloating and indigestion, an expectorant for coughs and catarrh, and a traditional galactagogue (milk-promoting) herb for nursing mothers. Commission E and WHO both approve its traditional use for catarrh of the upper respiratory tract and gastrointestinal spasms.[11, 12, 13, 14, 15]

Speedwell has a long European folk history as a mild digestive tonic and traditional expectorant for cough and respiratory complaints, and has also been used topically as a soothing wash for irritated skin; modern research on its iridoid glycosides supports a molecular basis for the traditional respiratory use.

Preparations

Crushed seed infusion (tea)[11, 12, 13, 14, 15]

The classic carminative preparation: crushed seed steeped in hot water.

Essential oil[11, 12, 13, 14, 15]

Concentrated aromatic fruit oil, used in small measured amounts in traditional formulations.

Not documented

Dosage

Crushed seed / essential oil[11, 12, 13, 14, 15]

Duke (2002): about 0.5-1 g crushed seed three times daily in tea, or 0.05-0.2 mL of the fruit essential oil. Food amounts up to about 20 g/day are generally considered safe for adults. Avoid medicinal doses in pregnancy and in children given limited safety data. Educational reference only, not a prescription.

Dangerous Lookalikes

Safety note[17, 18, 19]Fatal
Dangerous Plant: conium-maculatum
Confused Part: The plant's foliage - lower leaves broad and parsley-like, upper leaves fine and lace-like - and the umbels of small white flowers, plus the aromatic seeds, which resemble poison hemlock; and hemlock seedlings volunteering among planted anise.
Confusion Context: Anise (Pimpinella anisum) is a parsley-family herb that poison hemlock (Conium maculatum) is documented to resemble. King County (Washington) lists anise among the edible parsley-family plants poison hemlock can be confused with, and the North Carolina Extension Gardener Plant Toolbox lists Pimpinella anisum among the plants commonly confused with poison hemlock. Conium contains coniine and kills by ascending paralysis and respiratory failure - a few leaves or seeds can be fatal. Documented anise-specific poisonings are sparse, so the value of this record is the rock-solid tests below rather than a claim that this exact swap is common.
Distinguishing Features: SMELL (decisive): crushed anise foliage and seed smell sweet and strongly of licorice/aniseed. Poison hemlock smells rank, musty and mouse-like, with no sweet licorice note., Stem: poison hemlock has a hairless, hollow stem conspicuously blotched and streaked with red-purple, especially near the base. Anise stems are plain green and never carry purple blotches., Stature: poison hemlock is a tall (often 1.5-3 m) branching biennial; cultivated anise is a small annual usually under 0.6 m. A large fern-leaved umbellifer with a purple-blotched stem is not anise.
Key Test: Crush a leaf or seed and smell it, and look at the stem. A sweet licorice/aniseed scent with a plain green stem = anise. A musty/mousy smell and/or a hairless stem with red-purple blotches = poison hemlock - do not eat. If either warning sign is present, discard it.
