haema-

It comes from the Greek words, isch- to restrict and hema or haema meaning blood.

The term "hemorrhoid" comes from the Greek "haema" (blood) and "rhoos" (flowing).

In classical Latin poetry Haemus was drawn into association with the Roman civil wars; although geographically incorrect, it was attractive most likely because it was a homonym with the Greek word for blood (haema) and bloody (haimon), as well as for its connection to the singer Orpheus.
