This study evaluates the ability of corn silk (Zea mays L.) extract to function as a natural anti-inflammatory and anti-atopic therapeutic agent. The anti-inflammatory effects of corn silk were evaluated by measuring the inhibitory activities of nitric oxide (NO) and production of tumor necrosis factor-alpha (TNF-alpha). Anti-atopic effects were assessed by measuring the repression of thymus and activation-regulated chemokine (TARC). These results indicated that NICS-1 (corn silk ethanol extract) and NICS-3 (high maysin corn silk ethanol extract) functioned as anti-inflammatory agents by downregulating LPS-induced NO and TNF-alpha. Additionally, two extracts showed weak repression of TARC expression levels in tumor necrosis factor TNF-alpha plus IFN-γ induced HaCaT cells, respectively. These results suggest that corn silk extracts have anti-inflammatory and anti-atopic activities, and thus have the potential to reduce and alleviate the symptoms associated with atopic dermatitis.
