Based on the wide variations previously found in the level of effective ingredients in certain herbal supplements, it wouldn't be surprising if the old black cohosh was more pharmacologically active than some current product.

Heres a picture of what it looks like.Its a North American native so Im not sure what it would be called in Chinese.

To update the picture on black cohosh: this herb gained acceptance in recent years as an alternative medication to treat menopausal symptoms (picking up an endorsement from a major gynecology organization). Then a large clinical trial found that the herb did not provide benefits greater than placebo. Recent studies remain mixed, with this new report (involving a relatively small trial) showing that black cohosh didn't even do as well as placebo in relieving hot flashes and night sweats. On the plus side: testing for measures of brain function found no negative effects of black cohosh (by some measures of mental acuity, supplemental hormones can have detrimental effects). And while there are few reports of liver toxicity with black cohosh, it overall appears to a have a good safety profile.
