Pimpinella anisum
Pronounced Anise = AN-iss; Pimpinella anisum = pim-pih-NEL-ah an-EYE-sum
Warm, dry, and sweetly aromatic: a moving, relaxing carminative and warm expectorant that breaks up trapped wind, eases colicky spasm, and loosens a cold, congested chest.
Culinary and food amounts are recognized as safe (anise is GRAS in the United States). Concentrated medicinal doses and the essential oil are best avoided in pregnancy: anise seed carries traditional emmenagogue and abortifacient use, its anethole and dimeric phytoestrogens (dianethole, photoanethole) are mildly estrogenic, and the essential oil contains estragole, which is genotoxic and carcinogenic in rodents at high exposure. Adequate human safety data at therapeutic strength are lacking.

Anise has a long tradition as a galactagogue, and anethole is thought to raise prolactin by competitively antagonizing dopamine; a meta-analysis found a small increase in milk volume versus no treatment. Moderate, occasional culinary and tea use is generally considered compatible with breastfeeding. However, excessive maternal intake of an anise-containing herbal tea was linked to toxicity in two breastfed newborns consistent with anethole, and high-dose trans-anethole can both reduce milk output and cause neurotoxicity (seizures) in the mother. Avoid the concentrated essential oil and do not consume large medicinal quantities while nursing. Source: LactMed (NIH Drugs and Lactation Database), Anise monograph.
The seed as a mild tea or a dilute, sweetened syrup has a long history of use for infant and childhood colic, wind, and cough, and small culinary amounts are safe. Do not give the neat, concentrated essential oil internally to infants or young children owing to the risk of gut and mucous-membrane irritation and the potency of trans-anethole. Critically, avoid star-anise preparations in infants: products sold as star anise for colic have caused neurological toxicity and seizures in babies because Japanese star anise (Illicium anisatum), which is neurotoxic, is difficult to distinguish from and has adulterated Chinese star anise. Reserve essential-oil dosing for adults or qualified pediatric guidance. Source: LactMed; NCCIH; German Commission E (aniseed for dyspeptic complaints and respiratory catarrh); AAP/FDA case reports on star-anise neonatal toxicity.
Generally very well tolerated at culinary and normal medicinal seed doses. Anise essential oil is potent and rich in trans-anethole: high or undiluted oral doses can irritate the gut and, rarely, cause nausea; neat oil can irritate skin and mucous membranes and provoke allergic contact reactions (anethole is a recognized sensitizer). The seed and oil carry mild estrogenic activity, so use is cautious in estrogen-sensitive conditions. The oil contains a small amount of estragole (methyl chavicol), a compound genotoxic and carcinogenic in rodents at high exposure, so do not exceed recommended essential-oil doses or use the concentrated oil long term. Its warming, drying quality can aggravate hot, hyperacid, or acutely inflamed digestion and a dry, irritable cough. Do not confuse true anise (Pimpinella anisum) with star anise: Chinese star anise (Illicium verum) is a distinct but food-safe substitute, whereas Japanese star anise (Illicium anisatum) is neurotoxic and has caused seizures in infants given contaminated star-anise teas.
Avoid concentrated, therapeutic-strength preparations and the essential oil in pregnancy (culinary food amounts are recognized as safe). Avoid the neat essential oil internally in infants and young children. Use cautiously in known estrogen-sensitive conditions (estrogen-receptor-positive breast, uterine, or ovarian cancer, endometriosis, uterine fibroids) given the seed's mild estrogenic action. Use cautiously in hot, hyperacid, or acutely inflamed digestion and in dry, irritable, unproductive cough. Discontinue if an allergic or contact-sensitivity reaction occurs; cross-reactivity is possible in people allergic to other Apiaceae (fennel, caraway, dill, celery, coriander) or to anethole.
A widely cultivated culinary and commercial crop (the Mediterranean basin, the Middle East, Egypt, Turkey, Spain, and India); not threatened and not on the United Plant Savers at-risk list, which tracks native North American medicinals. Prefer organically grown seed to limit pesticide load. No wild-harvest conservation concern.
Not securely named in the canonical biblical texts. The King James Version of Matthew 23:23 reads that the Pharisees tithed 'mint and anise and cumin,' but the Greek word rendered 'anise' is anethon (Strong's Greek 432), which is dill (Anethum graveolens), not true anise; modern translations (NIV, ESV, NASB, RSV) correctly read 'dill.' True anise (Pimpinella anisum) is instead documented across the classical Mediterranean corpus: Dioscorides describes it in De Materia Medica (1st century CE), Pliny the Elder praises it highly in his Natural History as a breath-sweetener, digestive, and sleep aid, and the Romans baked the spiced 'mustaceum' wedding cake with it. Native to the eastern Mediterranean and western Asia and cultivated from ancient Egypt and Greece onward.
