Key Constituents
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.
The fruit's lipid fraction.
Metabolised in the body to salicylic acid - the 'natural aspirin' that gives the analgesic, anti-inflammatory and antipyretic effects.
Pharmacological Actions
Analgesic and anti-inflammatory for low back pain (moderate evidence; dose-dependent, around 240 mg salicin/day) - in an RCT, 240 mg salicin/day left 39% pain-free vs 6% on placebo within 4 weeks
Analgesic and anti-inflammatory for low back pain (moderate evidence; dose-dependent, around 240 mg salicin/day) - in an RCT, 240 mg salicin/day left 39% pain-free vs 6% on placebo within 4 weeks
Antipyretic (reduces fever)

Safety, Cautions & Contraindications
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.
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).
Because it works like aspirin, avoid willow bark if you are allergic to aspirin or salicylates, and do NOT give it to children or teenagers with a viral illness (risk of Reye's syndrome). Use caution in asthma (salicylate sensitivity).
Avoid with anticoagulant/antiplatelet medicines (bleeding risk) and in active peptic ulcer; avoid in pregnancy (especially the third trimester) and breastfeeding.

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.
Large deciduous tree (Salicaceae), 10-25 m tall (occasionally taller), fast-growing with a broad crown. Leaves are narrow and lance-shaped, silvery-white and silky-hairy beneath, giving the tree a shimmering appearance in the wind. Tiny flowers are borne in catkins appearing with the leaves in spring; the species is dioecious. The fruit is a small capsule releasing cottony-tufted seeds.[12]
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.
Native to Europe, western and central Asia and North Africa, growing on damp ground along riverbanks, floodplains and wet meadows; widely planted and naturalised elsewhere.[12]
Harvesting
Fruit ('seed') is harvested in late summer once the umbels have dried and turned brown, then threshed and dried further.
Bark is stripped from young branches (2-3-year-old growth is preferred, as salicin content is highest in younger bark) in spring, when the rising sap makes the bark peel most easily, then dried.[12]
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]
Willow bark has one of the longest documented histories of any medicinal plant, used since antiquity (recorded by Hippocrates) as a remedy for pain and fever. Its salicin content, chemically related to aspirin, gives it official European herbal-monograph recognition for mild joint pain, headache and feverish colds, with modern clinical trials supporting benefit for low back pain.[11, 12]
Preparations
Dosage
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.
Clinical trials for back pain have used around 240 mg salicin/day of standardised extract. Educational reference only, not a prescription; avoid if allergic to aspirin/salicylates, in children/teenagers with a viral illness (Reye's syndrome risk), or alongside anticoagulants.
