Figure 6: Effects of Danshen on NO production in liver and spleen homogenates. In addition to test cytokine production, the tissue homogenates were measured for NO production. Data for 0% Danshen ( of 14 separate experiments), 0.5% Danshen ( of 8 separate experiments), 1% Danshen ( of 10 separate experiments), and 2% Danshen ( of 9 separate experiments) are shown as mean ± SD; *indicates statistically significant difference compared to the 0% Danshen group.
