Rats were given a distinctive fluid (milk or grape) during recuperation from an injection of a noxious drug (apomorphine). Single-bottle tests conducted after treatment indicated elevated consumption of the fluid conditionally paired with recuperation. This positive "medicinal" effect is to some degree independent of initial preference, of novelty effects, and of aversive reactions to other substances paired with the onset of illness.
