Blood - Sanguine, (ad-Dam in Arabic)

One of the four temperaments, someone whose primary temperament is sanguinous (hot and moist) is enthusiastic, active and social.

One of the two extrovert personalities, “the talker”. 

It combines with a secondary temperament to produce variations on the theme. The secondary temperament of phlegmatic tempers the sanguine nature to produce happy, carefree people who like to help others.  Visitors rather than workers.

The Ibn Sina Institute has an excellent resources page giving information about which foods are best for those who are sanguinous.  Cherries, for example.
