Every effective drug provokes in the human body a sort of disease of its own, and the stronger the drug, the more characteristic, and the more marked and more violent the disease. We should imitate nature, which sometimes cures a chronic affliction with another supervening disease, and prescribe for the illness we wish to cure, especially if chronic, a drug with power to provoke another, artificial disease, as similar as possible, and the former disease will be cured: fight like with like.

I do not know if I am mistaken, but it seems that one can obtain more truths, important to Humanity, from Chemistry than from any other Science.

The highest ideal of cure is the speedy, gentle, and enduring restoration of health by the most trustworthy and least harmful way.

Only freedom from prejudice and tireless zeal avail for the most holy of the endeavours of mankind, the practice of the true art of healing.

There must be some limit to the thing. It cannot go on to infinity.

One might say, for example, that a patient has a kind of St Vitus's dance; a kind of dropsy; a kind of nerve fever; a kind of ague. One would never say, however (to end once and for all the confusion of these names) He has St. Vitus's dance, He has nerve fever, He has dropsy, He has ague, since there simply are not any fixed, unchanging diseases to be known by such names.

The highest ideal of cure is the rapid, gentle and permanent restoration of health; that is, the lifting and annihilation of the disease in its entire extent in the shortest, most reliable, and least disadvantageous way, according to clearly realizable principles.
