Footnote 11:

Cf. Plato Timaeus 89b-d (Jowett tr.): “Diseases unless they are very dangerous should not be irritated by medicines . . . if anyone regardless of the appointed time tries to subdue them by medicine, he only aggravates and multiplies them. Wherefore we ought always to manage them by regimen, as far as a man can spare the time, and not provoke a disagreeable enemy by medicines.”
