WP1-WP7 specialises in quality control, component extraction and chemical analysis, toxicology, in vitro and in vivo pharmacology, clinical studies and regulatory issues in commercial R&D respectively. WP8 is specialised in acupuncture studies and WP9 is dedicated to organising the Final conference of the consortium, at which a new European society will be launched to succeed the mission of the consortium.
