Abstract
The aim of this study was to investigate the effects of consuming 3.0 g of ginger powder containing 6-shogaol and 6-gingerol on skin temperature.
Subjects were 10 males. Subjects drank 3.0 g of powdered ginger that contained 60% 6-shogaol and 95% 6-gingerol dissolved in 200 ml of water. Skin temperature was measured using an infrared thermometer before consumption and at 15 min intervals over a course of 90 min after consumption. Measurements were taken on the cheeks, neck, and dorsa of the hands and feet. For statistical analysis, two-way repeated measures ANOVA. When interactions were detected in the abovementioned statistical analysis, multiple comparisons were performed using the Bonferroni method. A significant level was set at p<0.05.
After the consumption of the 6-shogaol drink, significant increases in skin temperature were observed in the cheeks and neck after 15 to 90 min; dorsa of the hands and feet after 15 to 45 and 90 min. After the consumption of the 6-gingerol drink, significant increases in skin temperature were observed in the cheeks after 90 min ; neck after 15 to 60 min ; dorsa of the hands and feet after 15 to 30 min. After the consumption of the 6-gingerol drink, significant decreases in skin temperature were observed in dorsa of the hands after 90 min, dorsa of the feet after 60 to 90 min.
