Luteolin reduces LPS-stimulated IL-6 production in plasma. Mice fed luteolin (0, 1, 2.5, or 5 mg/ml) for 21 days were injected with LPS (0.33 μg/g BW). At 4 h postinjection, mice were killed, and plasma was collected for IL-6 measurement. Bars represent the mean ± SEM (n = 9). Means with different letters are different (P < 0.05).
