Does the Lazurus pit cure mental illness?

This question came to mind since the Lazurus pit can resurrect a person from the dead and heal sickness and diseases and other medical condition. But can it cure mental illness?

Pretty sure Ra's is insane, so no.

Didn't the Lazarus Pit make Ra insane?

No the Pit actually causes it.

Exact opposite. People who are resurrected from the pit usually go crazy.

it causes it.

Doesn't it make people mental?
