Clinical observation on the correlation between moxibustion sensation and distance of moxa stick

Objective To explore the correlation between moxibustion sensation and distance of moxa stick and provide reference for clinical practice. Methods A total of 16 healthy volunteers aged 18-35 years old in college were recruited and given mild moxibustion at Shousanli (LI 10), Zusanli (ST 36), Shenshu (BL 23) and Tianshu (ST 25) with moxa stick, and the occurrence and frequency of moxibustion sensation were recorded at distances of 5 cm, 4 cm, 3 cm and 2 cm. Mild moxibustion scale was used to count the score. Results Warm was the main moxibustion sensation, burning pain and soreness decreased with the rise of distance; for the same acupoint, score of mild moxibustion scale increased with the decrease of distance; score ranged between 5.5 and 6.5 at distance 3 cm, which was the most comfortable distance for volunteers. Conclusion The distance of 3 cm is the most comfortable distance in mild moxibustion
