Don't have to "补" for stroke patients, what they need is healthy vegetable-rich diet.

Especially for thrombotic stroke, too much nutrients will cause cerebral vessels being obstructed even worse, so try to take some baby asparin daily.

For hemorrhagic stroke, there is really not too much you can do, except for waiting the clots to be absorbed by brain tissue gradually.

Regain of function is possible but very time-consuming.
