Bloodbending could help white blood cells fight whatever's gotten in your blood, or vice-versa. So Bloodbending can heal your cold or do the opposite. Right?
There have been many theories that have speculated that Bloodbending could have positive benefits. It'd likely be used for medical purposes.
However, I doubt any Bloodbender could bend Red or White Blood cells directly. They'd be too small.
What do you think?
