On 10 February 1995, a regulation of the Health Ministry was published describing the requirements for the registration dossier for herbal medicines . This new regulation replaced the previous one published in 1989 . According to this regulation, a simplified registration procedure for herbal medicines may be used if reference is made to the plants listed in Lists I - XIX. A list of indications for which the different groups of plants are traditionally used is also available. However, since the new regulation became effective, the indications are no longer introduced by the term "traditionally used in...." as was done previously. Combination products are not accepted if they contain more than three plants of one list or if the plants belong to different lists .
