Translation: "Like things are cured by likes"; or, "Similar ailments are treated successfully by similar remedies."

"Fight fire with fire." An example of this philosophy may be seen in the doctrine of homeopathy which advocates treatment of a disease by giving the sick person small amounts of substances that would produce symptoms of the same disease if they were given to a healthy person.

An opposite belief may be seen in Contraria contrariis curantur, or "Opposites are cured by opposites."
