Conception Vessel 23, Ren-23 Lianquan, Pure (or Clear) Spring, is the 23rd point on the Conception Vessel, one of the so-called 'Extraordinary' acupuncture channels.

It is right up there under the root of your tongue, but don't worry, you get at it from outside, not inside, your mouth! Good for when you lose your voice.

  • This point also lies on the Yin Wei (Yin Linking) channel.

Location of Conception Vessel 23

On the mid-line, in the angle between the throat and the chin, above the Adam's apple, just superior to and in the depression above the hyoid bone.

Another way of locating it is that it usually lies midway between the tip of the cricoid cartilage and the border of the mandible (ie the chin bone) - but you've still got to locate the cricoid cartilage which is the cartilage inferior to the laryngeal prominence, the Adam's Apple.

Needling and Moxa Ren 23

Point the needle directly upwards towards the vertex. Up to 1 cun. Tell the patient not to talk or swallow as the needle is being inserted, and preferably not while the needle is in place. (Which is easier said than done, and rather like telling somebody not to think of a pink elephant.)

Needle Sensation
Locally and under the tongue. It feels like a needle or fish-bone. Surprisingly many patients hardly feel the actual insertion through the skin, perhaps because of fewer nerves in that area.

Up to 7 cones, though some books forbid it here.

ACTIONS of Pure Spring

  • Eases the throat, tongue and voice
  • Helps to descend qi
  • Yin Wei point

Eases the Throat, tongue and voice

  • Stiffness in the throat or tongue as during a laryngeal or pharyngeal infection, or after a stroke
  • Lost voice, problems speaking
  • Coughing, especially from an itch high in the throat
  • Swelling and pain in the tongue or base of the tongue. (I used Conception Vessel 23, Ren-23 once in a patient whose tongue had swollen after it was stung by a bee he'd inadvertently chewed on.)
  • Difficulty breathing, particularly from swollen throat
  • Benefits fluid production in the mouth, though can also be used for excessive dribbling

Descends Qi

  • Helps energy descend, as during, for example, bronchitis, pharyngitis, tonsillitis, cough

Point of the Yin Wei channel

  • The Yin Wei (Linking) channel runs up through a number of very important points on the leg yin channels, starting in the region of Spleen 6 (though officially commencing at Kidney 9) but this is its first and last point on the Conception Vessel.
  • The Yin Wei channel is said to link all the Yin channels, so is yin promoting. In other words it nourishes, calms and moistens, and descends qi.
  • For these purposes, this point might be used with Kidney 9, or other points like Spleen 6.
  • For swelling under the tongue, Conception Vessel 23 was traditionally used with Pericardium 9 but for calming and grounding someone a more powerful point is Kidney 1.

However, it's all very well to suggest these points, but when you are very anxious and have lost your voice, you may not be very amenable to having this point and Kidney 1 needled.

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.)

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.

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.
