Substances Co-ordination Status page

Next steps in EMA Substances coordination

Notes: At least two countries have extracts for potential promotion, and the use case isn't clear as to how specific the concept needs to be.  Must the part of the plant be specified (root, seed, flower, bark, etc.)?  It is specified in drug/SPC labels.  However, of the 93 extract substances in the international edition, it's often not specified (neither is it specified in the country's potential promotions).  Must the extraction method (e.g., alcohol, water, CO2) be specified?  What about the form (powder, dry or soft extract, tincture, etc.)?  Consider the substances' use in allergy reporting.
