Nigella arvensis works primarily through thymoquinone, a bioactive compound with potent antioxidant and anti-inflammatory properties. This compound modulates immune responses by inhibiting inflammatory mediators such as prostaglandins and leukotrienes. Additionally, the plant contains saponins and alkaloids which contribute to its anthelmintic activity, helping to expel intestinal parasites. Evidence Level B indicates these mechanisms support its traditional use for respiratory and digestive ailments.
Does Nigella arvensis interact with medications?
Nigella arvensis may interact with anticoagulant and antihypertensive drugs. Thymoquinone can inhibit platelet aggregation, potentially increasing bleeding risks when combined with warfarin or aspirin. It may also lower blood pressure, compounding the effects of antihypertensive medications. Because it affects liver enzymes, it could alter the metabolism of various pharmaceuticals. Patients on medication should seek medical advice before use. Evidence Level C is based on pharmacological properties.
What is the recommended dosage for Nigella arvensis seeds?
The standard adult dosage for Nigella arvensis is 1 to 2 grams of dried seeds daily. The seeds are typically crushed and steeped in hot water to make a tea for digestive or respiratory support. This dosage is derived from Iranian traditional medicine practices. Users should start with the lower end of the range to assess tolerance, as higher doses may cause mild gastrointestinal upset. Evidence Level B supports this traditional dosing.
Is Nigella arvensis safe during pregnancy?
No, Nigella arvensis is considered unsafe during pregnancy. Traditional usage and pharmacological evidence suggest that therapeutic doses can stimulate uterine contractions, posing a risk of miscarriage or premature labor. Pregnant women should strictly avoid large doses of this herb. While small culinary amounts might be tolerated, medicinal use is contraindicated. Evidence Level B supports this safety warning based on uterine stimulant properties.
What is Nigella arvensis used for in traditional medicine?
Nigella arvensis is used in Iranian traditional medicine (Unani-Tibb) primarily for digestive and respiratory conditions. It acts as a carminative to relieve bloating and gas, and as a bronchodilator for coughs and respiratory infections. The herb is also employed topically for skin conditions and internally for worm infestations. Evidence Level B supports these uses based on phytochemical analysis and historical application.

Résumé
Nigella arvensis is a medicinal herb used traditionally as a galactogogue and anti-inflammatory remedy [PMID:30000936, PMID:28553226].
Contexte
Nigella arvensis is a species of the genus Nigella (Family Ranunculaceae) found in regions including the Aegean archipelago, Greece, and Turkey [PMID:37598984, PMID:19459745].
Usages traditionnels
It has been used orally as a galactogogue in India, Türkiye, and the Middle East [PMID:30000936], and is widely used as an anti-inflammatory remedy in the traditional medicine of Northern Africa [PMID:28553226]. In Turkey, it is also used for aphrodisiac effects [PMID:26281312].
Composés actifs
The seeds contain proteins (albumin, globulin, glutein-1, glutein-2, and prolamin) [PMID:28407892], amino acids including L-aspartic acid, L-leucine, L-valine, and L-tyrosine [PMID:39916614], and phytosterols such as β-sitosterol, stigmasterol, and campesterol [PMID:28553226]. Other identified constituents include glaucine, quercetin, kaempferol [PMID:32613127], flavonoids, and phenolic compounds [PMID:28541741].
Mécanisme d'action
β-sitosterol from N. arvensis seed extracts inhibits the expression of the pro-inflammatory neutrophil chemokine Interleukin (IL)-8 in bronchial epithelial cells exposed to Pseudomonas aeruginosa [PMID:28553226]. Seed extracts also stimulate Na+ transport in renal epithelia, an effect caused by adenosine [PMID:12409499].
Preuves cliniques
Preuve DLactation (Galactogogue)
No scientifically valid clinical trials support this use in humans; one study showed a slight increase in serum prolactin compared to placebo, but no evidence of growth promotion in infants [PMID:30000936].
Preuve DBacterial/Yeast Infections
Chloroform extracts of N. arvensis demonstrated potent antimicrobial activity against Gram-positive bacteria and yeast strains in vitro [PMID:19459745].
Sécurité et effets indésirables
Limited information indicates the herb is generally well tolerated, though black seed oil can cause allergic contact dermatitis [PMID:30000936]. In vitro testing of extracts (water, methanol, and chloroform) was conducted for cyto- and genotoxic potentials in rat kidney cells and Salmonella typhimurium [PMID:26281312].
Grossesse et allaitement
Used traditionally as a galactogogue [PMID:30000936]. However, no data exist on the excretion of components into breastmilk or the safety and efficacy of the herb in infants [PMID:30000936].
Synthèse des preuves
The available evidence is primarily based on in vitro studies, phytochemical analyses, and traditional use reports; there is a lack of scientifically valid human clinical trials.
