Quick question- how and why would their blood heal them?

I know a lot of semblances seem very unrealistic, but at least they follow pseudoscience. I'm over here wondering about why people want Shikamaru's shadow jutsu to be in RWBY and how blood healing works.

A more support oriented application of blood control (without the hardening and stuff) is blood doping. But it will not work if used for long periods of time.
