Mosquitoes and ectoparasites, such as ticks, fleas, lice, mites transmit a variety of diseases. Conventional medicine recommends synthetic pesticides and repellents as a means of protection. Many of the synthetic products are highly effective anti-parasitics, but they often contain neurotoxins. Side effects are very rare and often less dangerous than “damage” caused by the diseases that they can help avoid. Nevertheless, many users fear side effects and prefer organic substances that can be obtained from plant products. Black Seed, Nigella Sativa, also known as black caraway or black cumin is such a natural product, more precisely the oil obtained from the seed.

What is Black Seed Oil

Black Seed, Nigella sativa is an annual flowering plant that is native to North Africa and southwestern Asia. The seeds and the oil from the seeds have been used for medicinal and culinary purposes for centuries. It is used as an excellent spice worldwide and gives amazing flavors to cuisines. Its medicinal uses are so diverse that it has been used for various ailments in humans as well as animals ranging from mere toothache to fighting cancer and it has been boosting the immune system for centuries.


Extraction of Black seed oil

The oil is obtained from the seeds of Nigella sativa plant. After flowering, the annual plant forms fruit capsules in which the seeds are. When the plant has died, the fruit capsules are harvested and dried. The seeds are extracted from the fruit capsule and are freed from impurities. The seeds are then mechanically cold-pressed to obtain high- quality black cumin oil. The black cumin oil obtained in this way is characterized by a strong, pleasant smell and taste.

Active ingredient

Nigella Sativa oil (Black seed oil) mainly consists of unsaturated fatty acids, essential oils, a variety of vitamins and other trace elements.

The substances that give Nigella oil its insect and tick-repellent properties are the naturally occurring terpenes Carvacrol and Thymol found in many plants that act as a deterrent to insects.
