Abstract: Nigella sativa is a herb that has been used for centuries to treat various ailments, including infectious diseases. The aim of this work was to show in laboratory conditions the influence of different temperature regimes and methods of storage of Nigella Sativa oils on their physicochemical properties and microbiological stability. Analyzes have established that the temperature and method of storage have a significant influence on the change in the quality of the oil, especially when it comes to the total acidity of the oil and the peroxide value, where the values increased with the time of storage. The lowest obtained value for the peroxide number was at the first measurement, Pb = 9.99, which meets the prescribed standards for safe use, then the highest obtained value was 34.47 for the sample that was constantly exposed to the sun in a bright bottle. Also, the values of the iodine number increased with time, where the lowest value obtained was 14.56, and the highest was 102.48. Therefore, it is extremely important that the oil is stored in suitable packaging in dark glass bottles, and that it is protected from direct sunlight and high temperatures.
