Subjective Effects of Inhaling Kuromoji Tea Aroma

Area of Science:

• Herbal Medicine
• Food Science
• Physiology

Background:

• Kuromoji tea, made from a Lauraceae family shrub, is traditionally consumed in production areas.
• Despite long-term use, scientific investigation into kuromoji tea's subjective and physiological effects is lacking.

Purpose of the Study:

• To investigate the subjective and physiological effects of kuromoji tea consumption.
• To analyze the aroma's impact on sensory perception and physiological responses.

Main Methods:

• Measurements included heart rate variability, cerebral blood flow, and core body temperature.
• Subjective assessments and olfactory stimulation were employed.
• Chemical analysis identified key aromatic compounds like 1,8-cineole and linalool.

Main Results:

• Sniffing kuromoji tea aroma, particularly from leaves, induced a pleasant subjective feeling.
• The aroma demonstrated potential to stimulate saliva secretion.
• Increased subjective and physiological excitement in the oral cavity was observed.

Conclusions:

• Kuromoji tea aroma positively influences subjective feelings and physiological responses.
• The identified volatile compounds may contribute to these observed effects.
• Further research into the conventional consumption benefits of kuromoji tea is warranted.
