Research looking at components of 2 common TCM herbs, Huang Qi and Dan Shen when combined.
Huang Qi - Dried Astragalus Root
In this research they looked at 2 common TCM herbs (Astragalus root - Huang Qi and Salvia miltiorrhiza - Dan Shen) when combined and what their components are outside and inside of the body. What I like about this research is 2 things. First is that they looked at what happened when they used 2 herbs together. Most TCM herbal formals have between 4 and 12 herbs in them. Second, they looked at what happened in the blood plasma of rats once they ingested these herbs. (better if they used humans of course) Doing research like this is important because it more closely resembles what actually happens in clinic. Imagine doing research on what actually happens to patients when they go into a clinic:)
