From the 'Kukishinden Zensho' (九鬼神伝全書) by Agō Kiyohiko (吾郷 清彦), 1983. - Chapter 16 - Kukishin Kyū-hō (九鬼神灸法)

"The moxibustion whose objective is the adjustment of the antagonisms (antagonistic functions) of the sympathetic system and vagus nerve , promotes the adjustment of the motor functions of the muscles of the stomach and the endocrine functions of gastric glands and it accelerates the activity of tissue cells."

For this reason, the vital functions related on the stomach return to the normality and it can lead to self-cure of both hyperacidity and acid deficiency.
