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

  • also a meeting point on the Conception Vessel with the Kidney and Penetrating channels.

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 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 no overall Qi deficiency or 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.

Jonathan Clogstoun-Willmott Books

All the books in the 'Chinese Medicine in English' series should be fully accessible on Kindles and Kindle apps. (Or you can buy the softback print editions, of course.)

('Western Astrology and Chinese Medicine' published 1986, was never available in a Kindle version.)

Request! Please!

If, having read one of my books you can write a review - preferably positive - that would help others decide whether to read it.

You can put your review on Amazon or, on this site, here.

And if you think it was terrible?

Well, let me know so I can improve it for the next person. (Ideally let me know before cursing it in public!)

Here are some of the books I (Jonathan) have written.

Subscribers to Kindle Unlimited can borrow the first four for 'free'.

Qi Stagnation - Signs of Stress

Yin Deficiency - Burnout and Exhaustion

Yang Deficiency - Get Your Fire Burning Again!

Yuck! Phlegm! How to Clear Your Phlegm ...

Western Astrology and Chinese Medicine

Published 1986 and, amazingly, still selling. Western Astrology and Chinese Medicine was apparently used back then by at least one acupuncture college to help students understand Chinese medicine! See Reviews.

Seven Reviews so far for Yuck Phlegm. (Despite the lurid cover, it explains the five main types of phlegm and what works best for each type. I hope it's easy to read and will be much more useful than all the websites on the subject.)

3000 years of Chinese being stressed, and at last, here's a book showing how all that experience can help you!

By the author of this website, it explains in simple English how to use stress to improve and enhance your life.
