a Percentage inhibition of Cav3.2 currents by 10 µM concentrations of terpenes (n = 3). Error bars reflect standard error. b Structures of alpha-bisabolol (left) and camphene (right). c Percentage inhibition of transiently expressed Cav3.1, Cav3.3 and Cav2.2 calcium channels by 10 µM concentrations of alpha-bisabolol and camphene (n = 3). d. Effects of 10 μM alpha-bisabolol and camphene on native T-type currents recorded from cultured mouse DRG neurons (n = 3)
