The wise man should consider that health is the greatest of human blessings. Let food be your medicine.

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

In all abundance there is lack.

The natural force within each of us is that greatest healer of all.

To really know is science; to merely believe you know is ignorance.

That which is used - develops. That which is not used wastes away.

The body of man has in itself blood, phlegm, yellow bile and black bile; these make up the nature of this body, and through these he feels pain or enjoys health. Now he enjoys the most perfect health when these elements are duly proportioned to one another in respect of compounding, power and bulk, and when they are perfectly mingled.
