A compound or substance containing or derived from blood; sometimes used as a historical medical term (archaic).
From Greek 'haima' (blood) + '-man' or '-en' (suffix). An older, direct formation combining blood with a suffix to create a noun.
Most of these simple 'hema-' terms like 'heman' barely show up in modern texts—they're like fossils of medical language from when doctors were first trying to systematically name blood-related things!
