COMMENT: Root used as a tuber like potatoes, but tastes like artichoke.  For some people, the tubers must be soaked for 24 hours with two changes of water before cooking to avoid flatulence due to inulin content.  The tuber develops a pleasant sweetness during the winter, especially if subjected to frosts, and is then reasonably acceptable raw. Otherwise it is generally best cooked. The tubers bruise easily and lose moisture rapidly so are best left in the ground and harvested as required. The inulin from the roots can be converted into fructose, a sweet substance that is safe for diabetics to use. The roasted tubers are a coffee substitute. (1)

 

CAUTION: Inulin can cause flatulence.  Soak for 24 hours with 2 changes of water before cooking to guard against flatulence.

 

NUTRITION/MEDICINAL:  Aperient;  Cholagogue;  Diuretic;  Stomachic;  Tonic. Reported to be aperient, aphrodisiac, cholagogue, diuretic, spermatogenetic, stomachic, and tonic, Jerusalem artichoke is a folk remedy for diabetes and rheumatism. (1)
