Description

The present study was designed to investigate the effects of pungent components of ginger on the energy consumption, temperatures at some body parts, pulse rates and blood pressures in 19 young women with chilliness of their hands and feet. Under the conditions of 23∼24°C in temperature and 30∼40% in humidity, subjects took four capsules containing (1)placebo (starch only), (2)ginger extract equivalent to raw ginger 10 g, or (3)ginger extract equivalent to raw ginger 20 g with a sandwich and ad-lib water in different days. Energy consumption, temperatures at the tips of finger and toe, pulse rates, and blood pressures were measured at 1 hour, 2 hours and 3 hours after the intake. Energy consumption was calculated from O2 consumption, CO2 expenditure, and respiration quotient by a metabolic analyzer. As the results, intake of ginger extract equivalent to raw ginger 10 g generated 7.4%, 8.2% and 6.6% increases at 1 hour, 2 hours and 3 hours after the intake as compared with that of the resting (control) condition. And intake of ginger extract equivalent to raw ginger 20 mg generated 10.5%, 11.6% and 8.6% increases in energy expenditure at 1 hour, 2 hours and 3 hours after the intake. In conclusion, this study first elucidated the quantitative effect of pungent components of ginger on energy consumption in humans.
