The act or process of performing acupuncture; the specific technique of inserting needles into precise body points.
From Latin 'acus' (needle) + 'punctuatio' (from 'pungere,' to pierce) + English '-tion' suffix. This formal noun was created to discuss acupuncture treatment as a process or concept. The '-tion' suffix allows the action to be treated as an abstract noun.
This is basically the fancy way of saying 'the practice of sticking needles in specific spots,' but in medical and academic contexts, having a formal word makes it easier to discuss the technique seriously and precisely.
