Effect of Hypnotic and Nonhypnotic Suggestions on Parotid Gland Response to Gustatory Stimuli

Abstract
The parotid gland response to water was enhanced by the suggestion that the water was sour (citric acid), whereas the response to citric acid was depressed by the suggestion that the acid was tasteless (water). The suggestions were effective in altering salivary secretions when they were given with and also without a preceding hypnotic-inducing procedure.
