  • Into the heart of Black Seed

    Black seed, also known as “Habbatul Barakah”, is a remedy for all ailments according to common Islamic and Arabic belief. Nigella Sativa is mentioned in the bible, and was also described by Ancient Greek physicians such as Hippocrates, Pliny the Elder and Dioscorides.

    Traditionally in regions across the Middle East, black seed is recommended for conditions largely related to the respiratory system like bronchitis, coughs, asthma and chest congestion. It is also recommended for dysmenorrhea, obesity, hypertension and gastrointestinal problems. It can also be used externally for eczema and swollen joints. Now over 150 studies have been conducted to investigate the pharmacological properties of black seeds.

  • Traditional uses

    The traditional systems of medicine that feature black seed include Traditional Chinese, Islamic, Arabic, Malay, Unani, and African medicine, and Ayurveda.

    Black seed has been found in ancient archaeological sites in Turkey and Africa, most notably in the tomb of Tutankhamun, which is a testimony to how long humans have valued the plant.

    Both Dioscorides and Ibn-Sinna (Avicenna) valued black seed. Dioscorides mentions its use as a food, and also recommends it as a medicine for a variety of ailments including headaches, catarrh, respiratory issues, toothache, intestinal worms, leprosy, and skin eruptions to name a few! Ibn-Sinna valued it for treatment of arthritis.

    Black seed is also mentioned in several religious texts. It features in the Mishna, the Talmud, and the Bible.

    In India, black seed has used to treat fevers, to promote breast milk production, relieve digestive disturbance. They were also used as purgatives and for promoting uterine contraction to stimulate the afterbirth.

  • What practioners say

    Digestive system: As black cumin is a culinary herb, it has similar properties for the digestive system as other spices. This makes it helpful for easing wind or digestive spasm, bloating, and associated colicky pains. It can be added to cooking for these actions.

    It also has a reputation for assisting the treatment of intestinal worms. For this, it is advised to see a qualified herbalist.

    Reproductive system: In India, Nigella is frequently used to promote the production of breast milk. It is also considered an emmenagogue, which means that it may promote menstruation. Any herb with this action should not be used in pregnancy.

    Respiratory system: Traditionally the seed has been used as an expectorant and may help to reduce catarrh. The antibacterial, antitussive and bronchodilators effects of black seed are helpful in respiratory infections and asthma.

    Integumentary system (skin): Black seed oil is a well known product that can be used topically to aid in inflammatory skin conditions, such as eczema and psoriasis. It is a common addition to skin care routines, and may be added to an oil mix depending on what is needed.

  • Research

    There has been a good deal of study into Nigella sativa’s medicinal value, as it is has been considered a panacea for such a long period of time.

    Studies exploring the antimicrobial properties of the oil have found that black seed is antibacterial, antifungal and antiviral. The extract has been studied against antibiotic resistant Staphylococcus aureus and Pseudomonas aeruginosa with success. The extract was also found to be antifungal against Candida albicans. In another study, participants with hepatitis C were given black seed capsules for three months. The study found that the viral load decreased.

    Black seed has been investigated in asthmatic conditions with favourable results. It has demonstrated anti-inflammatory activity, a key aspect of the pathogenesis of asthma. It also improved expiratory flow. Bronchodilation and an improvement in pulmonary function in asthmatics was observed after a dose of Nigella.

    Nigella has been the subject of exciting studies investigating COVID-19 prevention and treatment. As inflammation of respiratory tissue is also included in the pathogenesis of Covid, Nigella’s benefits in patients with asthma also apply here. Nigella may also block the binding of SARS-COV-2 to ACE2 receptors. These properties are largely due to its secondary metabolites

    Nigella sativa’s potential as a cardioprotective agent has been studied. In a study containing 108 participants with mild hypertension, Nigella supplementation reduced both systolic and diastolic blood pressure. An animal study suggests that thymoquinone may improve lipid profiles.

    Black seed is highly antioxidant, due to the constituents found in the volatile oil. This has far-riding benefits for a number of pathologies, such as diabetes, asthma, and cancer.

    The use of black seed as an anthelmintic has been studied in children with cestode infections. The study found that the seed was beneficial at a dose of 40 mg/kg with no adverse effects.

    A small randomised control study observing participants with rheumatoid arthritis were treated with Nigella sativa oil for eight weeks. The study found that inflammatory cytokines and oxidative stress was significantly reduced in the treatment group.

  • Did you know?

    Cuneiform tablets in ancient Assyria have been found to explain the process of making a preparation for fumigation that included black seed. This preparation was used to dispel “ghost possession”.
