It is no time to go for the doctor when the patient is dead.

First of all, do no harm.

If you hear hoof beats, look for horses, not zebras.

Though physician to others, yet himself full of sores.

Don’t live in a town where there are no doctors.

If the doctor cures, the sun sees it; if he kills, the earth hides it.

Physician heal thyself.

In illness the physician is a father; in convalescence a friend; when health is restored, he is a guardian.
