European herbalism is the tradition that fed most modern pharmacognosy, so it is the one where trial evidence is least rare: several of these herbs have monographs from the German Commission E or the European Medicines Agency behind them. It is also the tradition most likely to be sold as a standardised extract, which matters because a dose that worked in a trial is a dose of a particular preparation.
