The anti-inflammatory effect of Phlomis viscosa extracts and compounds. The effect of Phlomis viscosa extracts and compounds on the secretion of pro-inflammatory cytokines, IL-6 (a) and IL-8 (b) by human dermal fibroblasts. The concentration of the extracts and compounds was 1 mg/mL. The final ethanol concentration was 0.1%. Untreated cells were used as controls. Cells treated with 0.1% ethanol (Control vehicle) were used to exclude the effect of ethanol on the cells. Data from three independent experiments are shown, (p < 0.001). * p < 0.05.
