Hippocrates

All excesses are inimical to Nature.  It is safer to proceed a little at a time, especially when changing from one regimen to another.

Let your food be your medicine, and your medicine be your food.

There are in fact two things, science and opinion; the former begets knowledge, the latter ignorance.

Cure sometimes
Treat often
Comfort always

Primum non nocere. (First, do no harm.)

Nature itself is the best physician.

If you are not your own doctor, you are a fool.

Life is short, the art long, opportunity fleeting, experience treacherous, judgment difficult.

To do nothing is sometimes a good remedy.

Male and female have the power to fuse into one solid, both because both are nourished in both and because soul is the same thing in all living creatures, although the body of each is different.
