The effect of compound and minor prescriptions of Radix Aconiti Lateralis Preparata, Rhizoma Zingiberis and Cortex Cinnamomi on sympathetic nervous system, adrenal gland, TSH and LH of rats was studied. Results showed that both prescriptions made the heart rate quicken, estrous cycle shorten, improved the adrenal cortex hormone and promote TSH and LH synthesis and secretion. The two Heat-nature products (Radix Aconiti Praeparata and Rhizoma Zingiberis) may be used instead of all the three products to make a Heat Syndrome animal model.
