The results of several clinical investigations showed the efficacy and safety of artichoke extracts (Cynara scolymus L.) in the treatment of hepato-biliary dysfunction and digestive complaints, such as sensation of fullness, loss of appetite, nausea and abdominal pain. Moreover earlier findings on a lipidlowering and hepatoprotective effect may be confirmed. In-vitro and in-vivo it has been possible to evaluate the underlying pharmacological mechanisms. Flavonoids and caffeoylquinic acids are mainly responsible for the observed actions.
