Implementation of safety-related statutory information for herbal products under the pharmaceutical legislation between 1965 and 2021 in Finland: a content analysis of product information

This study is based on a unique archive material covering years 1965-2021 in Finland. It shows successful national implementation of statutory product information for herbal products and how safety-related product information on contraindications (including special warnings and precautions) has improved during the study period, particularly since legislative changes in 2005. Currently, all herbal products under pharmaceutical supervision are medicinal products which are controlled like any other medicinal products for patient safety.
