Both essential oils showed activity against grade IV glioma cell lines (IC50 = 400 μg/mL), antimicrobial (MIC and MFC values of 2500 to 125 μg/mL), and anti-inflammatory (decreased level of IL-1β, IL-6, TNF-α, and IFN-γ in LPS-stimulated cells).The essential oils exhibited moderate antioxidant activity in ABTS (EC50 = 98 and 88 μg/mL) assay. The gene discussed is IFNG; the disease is central nervous system cancer.
