Zataria multiflora Boiss (Z. multiflora) belongs to the Lamiaceae family, is used traditionally for culinary and medicinal purposes. Different pharmacological effects have been described for the plant including; bronchodilation, vasodilation and effect on lung inflammation. The plant is also used as a remedy against cough in the traditional medicine. In this article, "pharmacological effects of Z. multiflora and its constituents focusing on their anti-inflammatory, antioxidant and immunomodulatory properties were reviewed" by searching various databases until "June" 2016. The anti-inflammatory effects of the plant such as decreased total white blood cell (WBC), neutrophils and eosinophils counts were demonstrated. The protective effects of Z. multiflora on serum levels of phospholipase A2 (PLA2) and total protein were showed. In addition, constituents of the plant, such as flavonoids and carvacrol also showed anti-inflammatory effects. Z. multiflora also reduced oxidative stress by scavenging free radicals and can be used in the therapy of oxidative damage. Decreased level of malondialdehyde (MDA) and protective effects of Z. multiflora on serum levels of nitric oxide (NO) were also shown. Improvement of the serum levels of IgE, reduction of pro-inflammatory cytokine (IL-4, TGF-β and IL-17), and increased anti-inflammatory cytokines (IFN-γ and FOXP3), were shown for Z. multiflora and its constituents, carvacrol and thymol. These results indicated that carvacrol and thymol could be used for treatment of inflammatory diseases as new anti-inflammatory agents. Therefore, Z. multiflora showed anti-inflammatory, anti-oxidant and immunomodulatory effects which could be used for treatment of inflammatory and immune-dysregulation diseases or disorders associated with increased oxidative stress.
