To further uncover the scientific significance and molecular mechanism of the Chinese herbs with pungent hot or warm natures, endogenous and exogenous expression systems were established by isolation of dorsal root ganglion (DRG) neurons and transfection of HEK293 cells with TRPV1 channel gene separately. On this basis, the regulation action of capsaicin, one main ingredient from chili pepper, on TRPV1 channel was further explored by using confocal microscope. Besides, the three-sites one-unit technique and method were constructed based on the brown adipose tissue (BAT), anal and tail skin temperatures. Then the effect of capsaicin on mouse energy metabolism was evaluated. Both endogenous and exogenous TRPV1 channel could be activated and this action could be specifically blocked by the TRPV1 channel inhibitor capsazepine. Simultaneously, the mice's core body temperature and BAT temperature fall down and then go up, accompanied by the increase of temperature of the mice's tail skin. Promotion of the energy metabolism by activation of TRPV1 channel might be the common way for the pungent-hot (warm) herbs to demonstrate their natures.
