Conception Vessel 17, Shanzhong, Middle of the Chest, nowadays often referred to as Ren-17, is the 17th point along the Conception Vessel acupuncture channel, and 

Location of Shanzhong

On the sternum midline, in the depression level with the 4th intercostal space.

On men Ren-17 usually lies at the level of the nipple when the man is supine. However, sometimes in people with very long chests, the point is slightly higher than you think it should be.

On women with heavy breasts, even when lying supine, the level of the nipples may not be an adequate reference point.

The best way I've found is to find the second rib, which is usually more protuberant than the others. Under the second rib is the second intercostal space. Count down to the second intercostal space below this, ie between the fourth and fifth ribs. Usually the point is level with where the medial end of this the 4th intercostal space adjoins the sternum. (But even then, it isn't always exactly there!)

Once you've located roughly where it should be, gentle palpate the area just above and below it to discover if there is any tenderness over a slight depression. If so, that's usually the point.

Needling Conception Vessel 17

Needle transversely, ie diagonally, under the skin either upwards, downwards or towards where the discomfort is felt. Depth under the skin up to 1 cun.

In very thin patients, the skin is almost sitting on the underlying bone, so it's impossible, or very difficult, to find Deqi easily. But you can still moxa it with great results - see below.

Some texts forbid needling Conception Vessel 17. I don't know why, although it is an important energy point, lying close to the underlying heart so perhaps the ancients feared the needle might enter the heart.

Nowadays we realise that unless, very unusually, someone has a hole in their sternum here, the sternum itself is a firm barrier between outside and the heart.

More likely is that some people have a very powerful response to this point. So needle it cautiously. If someone's qi is weak, don't manipulate the needle to strongly. Just get deqi and leave it at that. Perhaps consider moxa instead. However, the point can be very sensitive.

Neeedling sensation

Gripping, or a sensation pervading locally and within the chest. Sometimes although I've been sure I've got the point's deqi, the patient doesn't seem to notice much happening.

However, later on, it's clear the treatment worked. Correctly done, the needle sensation spreads to where you direct it.

Moxa is often excellent here. It can have a wonderfully enlivening effect, as if the patient has had a double dose of oxygen, or taken an enormous breath. Use up to 7 cones: not so many if the patient hasn't had it before.

If using a moxa stick, do so with caution as the skin is often thin here and the patient, especially if elderly, may not notice warmth before burning occurs.

However, where there is heat or damp-heat in the chest, I wouldn't use moxa. I'd needle instead, together with some points on the Stomach or Kidney channels, with other distal points to clear Phlegm or Heat. Only later, when these had cleared, would I consider moxa.

ACTIONS of Conception Vessel 17

  • Sea of Qi point
  • Mu-Alarm point of the Conception Vessel

Abundant, free-flowing Qi makes people positive, hopeful and want to get on with life. The point is usually tender in people who are downhearted, depressed, or sad, and its tenderness often suggests lowered spirits. Because of where it is, or because it's sometimes difficult to get deqi here, it's often used only to confirm a diagnosis.

However, Conception Vessel 17 can have a fantastically invigorating effect, boosting Qi circulation, which itself strengthens Blood and raising Spirits.

So, people's voices become stronger, tiredness evaporates, and they seem to resist coughs and colds better.

Moxa here makes chest mucus transform and descend.

However, as noted above, I'm cautious of using it where there is excess damp-heat or damp-phlegm in the chest. Where the mucus is white, clear and because of deficiency, this point is great.

It also regulates and suppresses rebellious Qi, such as Stomach Qi rebelling as in Oesophageal spasm, vomiting, regurgitation, belchings, acid risings and so on.

  • Subdues fullness of the chest.
  • Clears the Lungs: great for dyspnoea, coughing (particularly from deficient Qi)
  • Pain in the chest, arising from Lung or Heart imbalance, including coronary disease.
  • Asthma, emphysema
  • Resolves Phlegm (but see above)
  • Benefits the breasts (mammae): for pain in the breasts, mastitis, abscess or uncomfortable distension.
  • For deficient lactation, use moxa here and on Small Intestine 11.
  • Also useful for intercostal neuralgia.

In fact, Conception Vessel 17 can be used for almost anything occurring within the chest cavity!

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.
