What is black seed oil and what is its composition?
Black seed oil is a natural extract derived from the seeds of the annual herb Nigella sativa. The oil is produced through cold pressing, a method that preserves the seed’s valuable compounds. This approach helps retain essential fatty acids, vitamins, minerals, and bioactive components that contribute to its health-promoting effects. The oil is used both as a medicinal ingredient and as a flavoring in cooking.
The oil is rich in healthy fats, including unsaturated and saturated fatty acids such as Omega-3, Omega-6, and Omega-9, along with palmitic acid. It also contains trace minerals like zinc, iron, calcium, phosphorus, and copper, as well as vitamin E (tocopherols), and vitamins from groups A, D, and E. Beta-carotene and phytosterols are present too, contributing to its nutrient profile.
Among its key bioactive components, thymoquinone stands out for its antioxidant, anti-inflammatory, and potential anti-cancer properties. The oil also contains sterols that may support heart health by helping to maintain healthy cholesterol levels.

How is black cumin oil used in medicine, cosmetology and cooking?
In medicine
As with many active supplements, regular, long-term use is common to experience its benefits. It influences multiple body systems and has antibacterial, anti-inflammatory, immunostimulating, wound-healing, antipyretic, and antifungal effects.
In medical contexts, black seed oil is considered helpful because it possesses antiseptic properties useful for minor wounds and cuts. It may assist with joint and muscle pain associated with inflammatory conditions.
In cosmetology
In beauty routines, black cumin oil is valued for improving problem skin, supporting collagen production, and helping reduce wrinkles. It is frequently used in creams and face masks. The oil can moisturize and nourish dry skin and may help calm redness and itching from eczema or psoriasis due to its anti-inflammatory and antimicrobial qualities.
Overall, black seed oil is a strong ingredient in hair care as well, supporting hair strength, reducing brittleness, and potentially promoting growth. Its antifungal properties can help combat dandruff, and it is used as a massage oil to ease muscle tension and improve circulation.
In cooking
The oil adds a distinct flavor to dishes in small amounts and blends well with various sauces. It can be incorporated into porridges, soups, and vegetable dishes, and is also used with desserts, baked goods, main courses, and marinades. It pairs nicely with vegetables, grains, legumes, and meats and can be stirred into prepared dishes just before serving.
Moderation is key, as a strong flavor can overwhelm a dish. The oil should be cold-pressed and stored in a dark, cool place. Short shelf life after opening means small containers are best and proper storage is essential. It is not recommended for high-heat cooking like frying or stewing.
