Changes in salivary secretion rates induced by capsaicin and five basic taste stimulations. A: Mean salivary secretion rate during each stimulation. Capsaicin, NaCl and CA significantly increased salivary secretion rates compared with DW, and the enhancing effect of capsaicin was remarkably higher than other stimuli. B: Salivary secretion rate right after each stimulation. Salivary flow after capsaicin was significantly higher than any other stimulus. Error bar indicates standard error of the mean. *P < 0.05, **P < 0.001. CA = citric acid; DW = deionized water; MSG = monosodium glutamate; QHCl = quinine hydrochloride.
