Herb and chemo drug interactions not as common as made out to be

Despite the widely held belief that taking herbal medicines and conventional pharmaceutical drugs together may result in dangerous interactions, there is very little evidence to show that this is widespread.   While some preliminary studies conducted in vitro have raised concerns, when they are conducted in a clinical setting many show no evidence of an effect.  As the evidence-base grows, a reassuring lack of strong interactions in this arena is emerging as a theme.
