But a few things to note:
1) almost all of these herbal studies use an "extract" that may be much more concentrated than the herb.
2) some are dangerous. the herb mentioned above causes abortions. (the trial you mentioned excludes pregnant women, and requires males to promise to use condoms - so apparently even a small amount in sperm can threaten a pregnancy).
3) this particular trial is very preliminary. It is
open label (subjects know they are getting the herb, and whether they are high or low dose), and there is no control group. The main purpose of this study is to check safety and to see if there is any reason to do more research.
