Conception Vessel 7 Ren-7: Yin Jiao

Conception Vessel Points

Conception Vessel 7, Ren-7, is the seventh point along the Conception Vessel, one of the so-called ‘extraordinary’ acupuncture channels.

Location of Ren 7

One cun below the centre of the umbilicus, being one-fifth of the distance between the centre of the umbilicus and the superior edge of the pubic bone.

ACTIONS of Conception Vessel 7

Because Conception Vessel 7 is a meeting point with the Penetrating and Kidney channels, it can be regarded as being on those channels too. Each of the channels contributes its own kind of energy to the point. In remembering what the point does I find it useful to think of those other actions.

COMMENT on Yin Jiao

Although Conception Vessel points 4 and 6 are probably used more often, this is a greater point where indicated. For example, Conception Vessel 4 is a main point for nourishing Yin. But the name of this point, Yin jiao meaning Yin Crossing or Intersection, shows how it harnesses the other two most Yin channels (the Kidney and Penetrating channels).

For example, in menopausal flushes, where there is yin deficiency, this might be the better point.

The point isn’t always taught to beginners in acupuncture, being regarded, I suppose, as less important. But when indicated, it beats the rest.

For self-treatment with acupressure, the point is good when combined with other points above and beside the umbilicus for bowels disorders. But press and massage it gently, not hard.
