Abstract:

Zataria multiflora (ZM) is a thyme-like aromatic plant in the Lamiaceae family that grows in central and southern Iran. ZM is extensively used as a flavor ingredient in a wide variety of foods and is used as part of popular traditional folk remedies. In the present study, ZM essential oil (ZMO) was obtained from ZM leaves via hydro-distillation and then analyzed by GC-MS (gas chromatography-mass spectrometry). The anti-inflammatory activity of ZMO was determined via measures of NADH oxidase (NOX), inducible nitric oxide synthase (iNOS), tumor necrosis factor (TNF)-α, and interleukin (IL)-1β mRNA expression in lipopolysaccharide-stimulated murine macrophages using real-time polymerase chain reaction (PCR). GC-MS analysis indicated that the main components in the ZMO were carvacrol (29.4%), thymol (25.7%), p-cymene (11.2%), linalool (9.3%), and γ-terpinene (8.0%). ZMO significantly reduced NOX, iNOS, TNFα, and IL-1β mRNA expression in cells at concentrations of 0.1-1 μg/mL, indicating a capacity for this product to potentially modulate/diminish immune responses. ZMO has anti-oxidant and anti-inflammatory properties and could be potentially used as a safe effective source of natural anti-oxidants in therapy against oxidative damage and a number of inflammatory conditions associated with stress.

Oral Administration of Zataria multiflora Extract Decreases IL-17 Expression in Perennial Allergic Rhinitis

Background: Rhinitis, which occurs most commonly as allergic rhinitis and affects 20% of the world’s population, is a major health care burden causing significant morbidity. Considering the high prevalence of allergic rhinitis and anti-inflammatory effects of thyme, a favorite condiment, we performed a randomized clinical trial to determine whether thyme can relieve allergic rhinitis symp...

Catabolic cytokine expression in degenerate and herniated human intervertebral discs: IL-1β and TNFα expression profile

Low back pain is a common and debilitating disorder. Current evidence implicates intervertebral disc (IVD) degeneration and herniation as major causes, although the pathogenesis is poorly understood. While several cytokines have been implicated in the process of IVD degeneration and herniation, investigations have predominately focused on Interleukin 1 (IL-1) and tumor necrosis factor alpha (TN...
