The YNSA Basic point / Basic zone C

YNSA acupuncture is made up of two categories of points: YNSA Basic points and YNSA Ypsilon points. The Basic points are also referred to as Basic zones, because they actually correspond to an area about 2 cm wide x 4 mm high.

The YNSA Basic zone C is located on either side of the forehead at the hairline. It runs obliquely down along a line that, if continued, would dissect the pupil of the eye. In body acupuncture this corresponds roughly to the line connecting the body acupuncture points stomach 8 and gall bladder 14.

Prior to stimulating the C point or zone, the practitioner will carefully examine the scalp by touch (palpation), to determine whether there are any small hardenings or swellings within the C zone. Such swellings may be experienced as very painful or tender by the patient. If any point within the YNSA C zone tests positive, it is stimulated with a fine acupuncture needle.
