Black Seed Oil

Black Seed Oil (Nigella Sativa)

By Hwaa Irfan

Known also as fennel/Nutmeg flower, Love-Lies-Bleeding, Black Cumin/Caraway, or Roman coriander in English, the spice from which black seed oil is derived is native to Syria. Spreading from the Middle East to Africa, India, and Europe it is not to be confused with cumin, i.e. Cuminum cyminun/odorum the seed is used a popular spice in Middle Eastern cuisine, traditional and alternative medicine, and is often used to replace pepper in French cuisine. In India, the seeds may be placed amongst the linen to keep away insects, traditional Indian herbal medicine apply it as a carminative, for gastro-intestinal disorders, diabetes, inflammations, chest infections, and for fevers. In South East Morocco the seeds are used for hypertension, and diabetes.

Records reveal that it has been used for over 3, 000 years – seeds were found in the tomb of Tutankh-amun. Prophet Muhammed (SAW) said:

Use this black seed regularly, because it has a cure for every disease except death.” (Al Bukhari)

Known as faux cumin in French, schwarzkummel (German), tikur azmud (Amharic), habbet el-barakat (Arabic), kalo jira (Bengali), Sanuj (Catalan), hak jung chou (Cantonese), siah daneh (Farsi), kalanji (Hindi), chernushka in Portuguese, and jintan hitam (Malay), black seed belongs to the buttercup family, Ranunculaceae in the plant kingdom. The firm stems bear grayish-green leaves, and white – grayish-blue flowers. The seeds have a curious three corner shape, with two flat sides, and one convex with a brown-black exterior, and a white interior. Sown in the spring, the seeds ripen around the middle of summer carrying bearing a strong, pungent aroma..Once harvested the seeds must be kept in a cool dry place.

As the use of Black seed oil has become widespread, more names have popped up including black cumin oil, nigella seed oil, and black oil. It is obtained from the seeds through cold press extraction. The oil is thick in consistency, and has a deep-dark amber color with a strong pungent aroma. It should be bought in an amber bottle which prevents light from deteriorating the therapeutic value, and has a shelf life of 6 months if kept in a stable environment, but refrigeration is recommended.

When buying the oil, make sure that it is labeled cold pressed, and solvent free because it has been known to be extracted using a petroleum-based process.

Thymoquinone protects against nephrotoxicity and hepatotoxicity (pertaining to the liver) induced by either disease or chemicals. The oil has demonstrated strong anti-inflammatory qualities against encephalomyelitis, colitis, peritonitis, edema, and arthritis by suppressing prostaglandins and leukotriens which lead to inflammation.

The African Journal of Traditional, Complementary, and Alternative Medicine published findings that black seed extract cured an HIV patient in August 2013. A complete recovery was experienced experienced with no detectable HIV virus or antibodies against HIV in their blood serum, both during and long after the therapy ended.

This oil is a powerful antioxidant preventing the deterioration of cells. As an emmenagogue it stimulates menstruation in cases of suppressed menses, and as a galactagogue it stimulates lactate ion in nursing mothers. It is a tonic to the immune system by increasing antibodies, a tonic to the liver by strengthening the function of the nephrons, and detoxifying the liver. Its qualities as an anthelmintic means that it destroys and expels worms, as an analgesic it relieves pain whether taken orally or applied externally, and as an antipyretic it reduces fever. As a carminative the oil promotes the discharge and flow of bile from the gall bladder into the small intestines by disinfecting the bowels.


  • Digestive problems, constipation
  • Congestion of the liver
  • Diabetes
  • Sluggish lymphatic, vascular system
  • Delayed menses
  • High blood pressure
  • Exhaustion, anxiety, depression
  • Skin infections, acne
  • Colds, flu
  • Hair loss
  • Allergies(especially ears, nose and throat)
  • Chest infections
  • Nursing mothers


There is low adverse reaction to black seed oil, but allergic dermatitis is possible for those with sensitive skin in its concentrated (absolute) form. It should not be used in conjunction with antibiotics, and anti-inflammatories. Ingestion can cause gripe, and the estragole content makes it unsuitable for pregnant women, and its anti-oxytocic qualities also makes it unsuitable for pregnant women, by preventing contractions. It is also unsuitable for those who suffer from low blood pressure.


Can be taken orally for the treatment of allergies, arthritis, anxiety, bruises, cold symptoms, diarrhea, headaches, high blood pressure, flu, sore muscles, rheumatism, and stomach problems.

It can be applied directly to the scalp for hair loss

It can be applied directly to non-sensitive skin for the treatment of fungal infections (I have recently used it successfully in the treatment of psoriasis of the skin)

It can be rubbed on the back for treatment of asthma, and chest infections

It can be massaged on the stomach for colic

Dripped into the ear for infections of the ear

It can be rubbed on the forehead for headaches.

Applied in vapour therapy (though the smell maybe disliked by some) for acne, asthma, coughs, and allergies.

    Dr.Abu rendered to me, I am here to give my testimony about Dr.Abu
    who helped me in my life. I was infected with HIV 4 years ago, i went

    someone said Dr.Abu cured a woman who also had HIV infection and then i
    saw yet again another woman saying Dr.Abu cured her of Herpes and that he could cure any illness.
    so i decided to give it a try and contacted Dr.Abu, I told him i was HIV positive for 4

    • If you have had psoriasis for 33 years, there is an underlying disturbance meaning the psoriasis is a symptom not the cause. It is the cause that needs to be addressed which is best done through homeopathy (a reputable practitioner. This takes time, but is 100% effective overall.
      In the case of Black Seed Oil, I would strongly recommend through inhalation. By this I mean a tiny drop in boiling hot water with a towel over your head, and inhale for as long as you can. The oil has a strong smell, but if you allow yourself to adjust to it, it gets easier. Do this thrice a week.
      In the meantime, eliminate dairy products from your diet, and increase fruits which will helps to cleanse and detoxify your blood
      Wishing you the best.
