Can Nigella Sativa Help Treat Arthritis?

Nigella sativa, Latin for “black cumin” or “black seed,” is an annual herb with a lifecycle of a year. Called Habbatul barakah (the seed of blessing in Arabic), Nigella has a mighty reputation in various systems of traditional medicine and in different Asian cuisines. The seeds and seed oil of this “miracle herb” even get a mention in the Quran and the Bible. In Ayurveda, too, the seeds of Nigella sativa are used as an astringent, stimulant, diuretic, emmenagogue, and antiparasitic, and to cure jaundice, dyspepsia, intermittent fever, piles, and skin diseases.1

Can This Miracle Herb Cure Arthritis?

Nigella’s therapeutic properties are largely due to the presence of thymoquinone, a major bioactive component of its essential oil.2 Thymoquinone is proven to have

Rheumatoid Arthritis (RA) is one of the most disabling illnesses of today’s time, affecting over a million Americans.4 As physicians and rheumatologists try to expand their understanding of this complex autoimmune disease, researchers are also looking at natural cures. And Nigella sativa, endowed with so many curative properties, seems poised to deliver.

One placebo-controlled study examined the effectiveness of Nigella sativa oil in managing RA. Among the experimental group comprising 40 women, the disease activity score DAS-28, a measure of RA activity, significantly reduced after they were given capsules with black cumin oil for a month. There was also improvement in the number of swollen joints and in the duration of morning stiffness. This study recommended that supplementing Nigella with disease-modifying anti-rheumatic drugs (DMARDs) could be an affordable adjuvant biological therapy.5

How does Nigella work? There is ample evidence that T lymphocytes – a type of white blood cells produced by the thymus gland in the neck – play a major role in RA.6 Studies show that black cumin oil has the potential to treat RA by modulating the action of T lymphocytes.7

While more than one study has shown the effectiveness of black cumin seeds (or its extracts) in treating the symptoms of arthritis,8 more in-depth studies will help prove the complete efficacy of its properties.

Precautions

Be really careful when you take either thymoquinone or the seed extract . Thymoquinone has been found to have cytotoxic effects (leading to cell death) and can cause damage to the DNA in liver cells if not used correctly.9 Based on animal studies, the toxicity for humans has been determined to be approximately 0.28 mg/lb/day for thymoquinone extract10 and 0.023 mL/lb/day for the seed extract.11

Also, due

to its hypoglycemic properties, the seed extract should be used with caution by pregnant women and children.12 Dosage of below 40mg/lb is considered safe in children.13 However, care must be taken to ensure that weight-adapted doses are administered and only after meals.

Diabetic patients are also advised to consult their physicians before taking black cumin seed extract.14
