Artichoke extracts are usually made from the leaves. Such an extract is not the same as the edible part of an artichoke or any plant powder. Assessment depends on the plant part, extraction method and information for the specific preparation.
Digestive symptoms and traditional use
The EMA describes certain artichoke leaf preparations for relieving digestive symptoms such as fullness and bloating on the basis of traditional use. This is not confirmation from large, conclusive clinical trials. The assessment concerns defined preparations, not automatically every mixture on the market.
Claims about healing the liver, general ‘detoxification’ or treating raised blood lipids each need their own appropriate evidence. Traditional digestive use does not answer these other questions.
When self-treatment is inappropriate
Do not self-treat with artichoke preparations if you have a bile duct obstruction, gallstones or other liver or biliary disease. Relevant artichoke leaf medicines must not be used by people allergic to the daisy family. Persistent upper abdominal symptoms or abnormal liver blood tests need assessment.
Tolerability and product information
Possible effects include diarrhoea with abdominal cramps, nausea, heartburn and allergic reactions. New symptoms are not desirable cleansing. Follow the product information and age restrictions; discuss pregnancy, breastfeeding, other medicines or existing conditions with a professional beforehand.
