The National Doctors' Day falls on March 30 ― a day to celebrate medical professionals across the United States and to appreciate their contribution in saving endless lives every day.

From minor cuts and bruises to mental health, the human civilization, especially with the advancement of science and medicine, has learned to rely on doctors for every issue plaguing the body and mind. So it was only a matter of time before the importance of medical professionals was recognized.

The National Doctors' Day was introduced by Eudora Brown Almond, wife of Dr. Charles B. Almond, to mark the first time ether was used to anesthetize a patient. It was later signed into law in 1990 by former President George H. W. Bush, which designated Doctors' Day a national holiday.

To celebrate this occasion, here are a few inspirational quotes about medicine and doctors, collected from Quote Garden and Gold Medal Waters:

"[Being a doctor] offers the most complete and constant union of those three qualities which have the greatest charm for pure and active minds – novelty, utility, and charity." ― Sir James Paget

"In nothing do men more nearly approach the gods than in giving health to men." ― Cicero
