The current scientific understanding of the role the gut flora play in the metabolism and activity of various classes of constituents from medicinal herbs will be reviewed. The little-known microbes involved in these transformations will be discussed as important but largely overlooked members of the gut flora. A discussion of how to promote the health of these microbes will be included. Flavonoids, glycosides, lignans, and saponins will be the main focus of these discussions, involving herbs as diverse as Arctium lappa, Panax ginseng, Arctostaphylos uva-ursi, Arbutus menziesii, Glycine max, Linum usitatissimum, Glycyrrhiza glabra, and Reynoutria cuspidatum. Early indications of serious harm to these vital interactions by drugs, primarily antibiotics but also others such as anastrozole, will be presented.
