Black seed

Black seed: what was it used for?

A spice and a carminative. Dutt records that the seeds were regarded in Sanskrit medicine as aromatic, carminative, stomachic, and digestive, used in indigestion, loss of appetite, fever, diarrhoea, and the diseases that follow childbirth, and given to newly delivered mothers to increase their milk. Dymock, Warden, and Hooper add that Hindu physicians prescribed it with other aromatics and plumbago root in dyspepsia, and that the Hakeems thought it increased the menstrual flow and the milk and stimulated the womb. Grieve and Dutt both record its use all over India to keep insects out of linen and woollen clothes.

Black seed: what does modern science say?

No European monograph covers it. Recent meta-analyses are favourable on risk factors for heart disease: one of thirty-one trials in people with metabolic disease (2026) found modest falls in weight, blood pressure, fasting blood sugar, and HbA1c, though none in insulin resistance or waist size, and urged caution given the variable quality of the studies; one of sixteen trials in type 2 diabetes (2025) found lower fasting glucose, HbA1c, total cholesterol, and LDL cholesterol; a third, of eighty-two trials (2025), called it “a promising adjunct therapy” for cardiovascular risk factors; and an umbrella review of seven meta-analyses (2025) found lower markers of inflammation and oxidative stress. LiverTox, revised in 2023, takes a cooler view: the effects shown in cells and animals have not been consistently demonstrated in human trials, and the effects on cholesterol, blood sugar, and blood pressure are modest, so that “the overall evidence for clinical benefit of these effects, however, is not very convincing.”

Black seed: what did the older authorities say?

Dioscorides, De materia medica (1st century), book 3

Dioscorides describes melanthion as a little shrub with a poppy-like head full of black, sweet-smelling seed that was sprinkled on loaves. He applied it to the forehead for headache, with vinegar for freckles and hard lumps, and as a mouthwash for toothache; taken for several days, he says, it brings on menstruation, urine, and milk, and he adds the report that it kills if a great deal is drunk. The translators of the modern English version identify it, among other nigellas, as Nigella sativa, and mark it poisonous.

Dymock, Warden, and Hooper, Pharmacographia Indica (1890)

Following Birdwood, they take it to be the black cummin of the Bible, the melanthion of Hippocrates and Dioscorides, and the gith of Pliny, and conclude from its Sanskrit name that it “must have been long known in India.” It was sprinkled, with sesame, on the bread of Muslim bakers.
