Characterization of the Physiological Response following In Vivo Administration of Astragalus membranaceus

Figure 3

AM effect on circulating platelets. Subjects 1, 2, or 3 (indicated by blue, red, and green lines, resp.) were administered vehicle or varying concentrations of AM extract (0.25, 0.75, and 1.5 mL extract/kg body weight). Blood draws were performed 0, 4, 8, 12, and 24 hours after administration to measure total platelet cell numbers. Peak fold changes relative to baseline ( hours) are indicated. Normal physiological ranges of the different cell populations are indicated by black bars.
