[Comparative effects of decreasing viscosity in different preparations of Chinese angelica root and ginseng]
Objective:
To compare the effects of different preparations of Chinese angilica root and ginseng on decreasing whole blood viscosity and plasma viscosity in rats.
Method:
The hemorheological method was used in vivo or in vitro and a Decreasing Viscosity Index (DIV) was defined as a comparative scalar.
Results:
In the effect of the groups of Chinese angilica root on decreasing viscosity, the effect of whole root group was the best and the effect of main root group was better than that of the tributary root group. Meanwhile the same effect of transplant wild ginseng group was greater than that of dried raw ginseng group.
Conclusion:
This work provided some fundamental evidences for clinical application and pharmacological data for the quality evaluation.
