.This thesis deals with the safety of herbal preparations on the Dutch market.  It is a doctoral thesis by MJ Martena submitted tot he University of Wageningen.

An overview is given of the Dutch and European legislation on the subject.  Subsequently, data is presented on the percentage of banned substances found in herbal preparations on the Dutch market.  Among other things, lead, mercury and arsenic content is discussed.

It is concluded that, of course, the term does not necessarily equate to ‘safe’.  However, it is necessary to keep European and Dutch legislation up to date as there are several gaps in the net.  Covering this up should ultimately protect the consumer better.
