Eugenol but not carvacrol reduces detection of weak tactile stimulus. A. Eugenol. Significant difference in R-index measure of detection of weak (0.08 mN) von Frey stimulus between eugenol- vs. vehicle-treated side of tongue (*: p=0.45, paired t-test, n=30).Eugenol had no effect on detection of the stronger (0.2 mN) von Frey stimulus. B. Carvacrol had no effect on stimulus detection (format as A, n=29).
