In Vitro Studies on the Immunomodulatory Effects of Pulicaria crispa Extract on Human THP-1 Monocytes

Figure 1

The effect of P. crispa extract on proliferation of THP-1 cells. The -axis shows absorbance at 490 nm after incubation of cells treated with DMSO alone, 50 μg/ml or 100 μg/ml of P. crispa extract relative to untreated cells (control). value < 0.01 (treatment vs. control). Values represent the mean of three different experiments done in for each time point tested. Statistical analysis was performed using the test.
