Components

血 xuè

blood

A pictograph of a sacrificial vessel 皿 with a single drop above it - the drop of blood being offered. Oracle-bone forms show the drop clearly inside the bowl. 血 is itself a Kangxi radical and indexes a small family of blood-related characters such as 衅 (to smear with blood) and 衄 (nosebleed).

Radical

Blood Kangxi #143

A small ritual radical: 血 indexes a handful of blood-and-rift characters (衅, 衄, 衊). The graph shows a drop above a sacrificial vessel 皿 - originally depicting blood smeared on ritual implements during sacrifice. Low productivity in modern Chinese; most blood-related vocabulary builds on 血 itself rather than chars filed under this radical.
