It is worthy to mention that Arisarum vulgare, Arum palestinum and Arum
hygrophillum belong to the same family Araceae and are used to prepare one of
the famous national foods in Jordan (jahjeel) and are also used in folks medicine
as anticancer. The reported active (cytotoxic) plants in this study are worth of
further pharmacological and phytochemical studies in order to define what kind of
antitumor activity they have (if any) and to isolate the natural active constituents,
which are responsible for the activity.
