Nigella sativa (N. sativa) in the family of Ranunculaceae, has been traditionally used as food additive and spice. N. sativa showed protective effects on respiratory system including; trachea responsiveness and lung inflammation in various animals models studies. The possible therapeutic effects of N. sativa on asthma were investigated in this systematic review study.

All unrelated articles such as duplicates, animal, and review studies as well as clinical studies without control group were excluded from obtained studied. Then 9 articles were considered for further evaluation.

After analyzing 9 articles including 434 participants, these following results were achieved: N. sativa improved the asthma control test (ACT), and pulmonary function tests (PFTs) values, while reduced respiratory symptoms including, cough and wheeze. Furthermore, N. sativa, reduced eosinophils count and serum levels of pro-inflammatory mediators such as IL-4 and immunoglobulin E (IgE), while increased production of anti-inflammatory mediator such as IFN-γ in the serum.
