Black cumin, also known as Nigella sativa, is an herb with a long history of use for an impressively wide range of health conditions. Black cumin has been used as crushed seed, oil, and as a water extract. One of the identified active ingredients in black cumin is thymoquinone, a compound that is known to have anti-inflammatory and antioxidant effects. Black cumin oil also contains plant sterols, as well as 25% oleic acid, 55% linoleic acid, and volatile oils including thymol, limonene, and carvacrol.
In humans, black cumin has been shown to have antidiabetic, blood-pressure-, and cholesterol-lowering effects. It also has activity against specific types of infection, possesses antiallergic effects, and improves rheumatoid arthritis as well as pediatric seizures.

Human Trials of Black Cumin Seed Oil


Metabolic Syndrome

n = 88 subjects with TC > 200 mg/dL
2 g crushed black cumin seeds or placebo (in 500 mg caps) × 4 weeksSignificant decreases in TC (4.78%), LDL (7.6%), TG (16.65%).
No change in fasting glucose or HDL.
Type 2 diabetesRCT of 3 black cumin doses, no placebo; n = 94 patients on medication with insufficiently controlled glucoseBlack cumin seeds at 1, 2, or 3 g daily × 3 monthsThe 2 g‑dose group had significant reductions in fasting glucose, 2 h postprandial glucose, and HbA1c, without significant change in body weight.
The 1 g‑dose group showed nonsignificant trends toward improvement, while the 3 g‑dose group had no advantage over 2 g.
Metabolic syndromeRDBPCT;
n = 40 obese men with no more than stage I hypertension and normal or impaired glucose
1.5 g black cumin seed or placebo × 3 monthsBody weight, waist circumference, and systolic blood pressure decreased in the black cumin group only (p < 0.05 for all compared to baseline), while these increased in the placebo group:
· body weight 77 kg → 72 kg at 3 months;
· waist circumference 101 → 99.8 cm;
· and systolic BP 130 → 121.
Metabolic syndrome componentsRDBPCT;
n = 123 patients
Black cumin seed (dose not reported), or placebo“Favorable impact of powdered N. sativa (Kalonji) seed in capsule was noted on almost all variables [body-mass index, waist-hip ratio, blood pressure, fasting blood sugar, lipids, ALT, and creatinine], but results were not statistically significant because of small sample size.”
n not reported; patients with “mild hypertension”
100 or 200 mg black cumin extract twice daily × 8 weeks, or placeboThere was a reduction in systolic and diastolic blood pressure in both black cumin groups, in a dose-dependent manner, that was significant compared to placebo (p < 0.05 for all). In addition, there was a significant reduction in TC and LDL compared to baseline in the black cumin group (p value not reported).


Allergic rhinitisDBPCT;
n = 66 patients
Black cumin oil × 30 days (dose not reported), or placeboBlack cumin reduced the presence of the nasal mucosal congestion, nasal itching, runny nose, sneezing attacks, turbinate hypertrophy, and mucosal pallor within the first 2 weeks of treatment.
n = 29 asthma patients
15 mL/kg of 0.1 g% boiled aqueous extract daily × 3 months, or placebo solutionIn the black cumin group the following symptoms improved significantly 3 months compared with baseline and with placebo: asthma symptoms, frequency of asthma symptoms per week, chest wheezing, and pulmonary function tests.
Requirements for medications decreased in the black cumin but not in the placebo group.
AllergyReport of 4 trials;
n = 152 patients with allergic diseases (allergic rhinitis, bronchial asthma, atopic eczema)
Black cumin oil: 40–80 mg/kg/dSubjective report of symptoms severity improved with black cumin treatment.


Helicobacter pylori and dyspepsiaRCT;
n = 88 patients with dyspepsia and positive H. pylori breath test
4 groups: i) triple therapy or ii) 1, 2, or 3 g black cumin in addition to omeprazole × 4 weeks; black cumin as ground seed.H. pylori eradication was 82.6, 47.6, 66.7 and 47.8% with triple therapy, and 1 g, 2 g, and 3 g Nigella, respectively. Eradication rates with 2 g black cumin + omeprazole and triple therapy were not statistically different.
Dyspepsia symptoms improved in all groups to a similar extent.

Combination of black cumin 360 mg and Phyllanthus niruri 50 mg extract 3×/d × 7 days, or placeboThe black cumin extract led to relief of the pain and difficulty of swallowing within a few hours after the first dose.
