Conception Vessel 15, Ren-15, is the fifteenth acupuncture point on the Conception Vessel, one of the body's 'Extraordinary' channels.

Reasons for the Name of the point?

Its location, at the base of the zyphoid process, looks like the tail of a turtledove, with the bank of ribs on either side resembling the bird's wings. 

However, I think the Chinese may have chosen its name because the tail of the bird suggest that it is ascending, that it has a strong affect on the mind (as it does), with the wings beating downwards to push the bird upwards. Also of course, the back-end of the bird faces the stomach and abdomen, where food goes to power the flight. 

All these images suggest uses for the point.

It is also:

  • The 'luo-Connecting' Point or 'Junction' Point of the Conception Vessel
  • the Source point of the 5 Yin organs (the Heart, Lung, Spleen, Kidney and Liver energy organs)


1 cun down the mid-line from the sternocostal angle, or 7 cun above the centre of the umbilicus. Traditionally this is supposed to be at the tip of the zyphoid process, but in practice it isn't, because the zyphoid process can be so long that it reaches almost to Conception Vessel 14, the next point. So the point can lie above, on or below the tip of the zyphoid process. You just have to feel for it!

Needling Conception Vessel 15

Diagonally downwards, up to 1 cun. If needling below the tip of the ziphoid process, take care not to penetrate too deep, especially in thin people, in case of puncturing the peritoneal cavity. 

If the point is inferior to the tip of the zyphoid process, never needle this point obliquely upwards towards the heart.

Needle Sensation

Locally and upwards, inside the chest.


Up to 5 cones. Some texts forbid moxa here.

ACTIONS of Conception Vessel 15

  • Clears, Calms and Strengthens the Mind and Heart
  • Steadies the 5 Yin 
  • Helps Descend Lung Qi and fullness in the lungs
  • Regulates Digestion, the functions of the Spleen and Stomach

Clears, Calms and Strengthens the Mind and Heart

The point is one example of points for opening the orifices of the Heart, meaning it helps to clear Phlegm from the Heart. That means it helps many situations of unclear mind, including:

  • Fits 
  • Mania
  • Crazy, foolish behaviour, singing and dancing, prancing inappropriately
  • Hatred or disgust for the sound of human voices
  • Manic-depression
  • Mental illness
  • Excessive anxiety

Physically, it helps 

  • Palpitations
  • Angina Pectoris
  • Full, heavy sensation in the chest and heart region

Steadies the 5 Yin

In the above situations Conception Vessel 15 is used to dissipate excess or fullness. However, it can be used to strengthen Yin and Blood, to provide a stronger basis for the personality.

  • As source point for the five Yin organs, it brings to them deep reserves of the body. So this point, when used appropriately, can give you a new lease of life
  • Itching of the skin of the abdomen 

Helps Descend Lung Qi and fullness in the lungs

  • Asthma
  • Difficulty breathing
  • Fullness in the chest
  • Cough and haemoptysis (coughing up blood)
  • Sore throat
  • Swollen throat and inability to swallow
  • Deficient Qi
  • Sighing excessively

Regulates Digestion, the functions of the Spleen and Stomach

  • Gastric or abdominal pain
  • Hiccup
  • Motion sickness
  • Nausea
  • Poor digestion
  • Dysentery and weakness of the digestion
  • As the 'luo-connecting' point of the Conception Vessel, it reaches all over the abdomen so can be used with other treatments for a range of conditions, including infertility and menstrual problems

The point is also used, with Governor 20, for anal prolapse. For example one might moxa Governor 20 and this point. 

However, some people have both manic conditions and anal prolapse in which case probably their condition is more one of excess. In that case one might initially calm or dissipate energy at these or other points. 

Later when yin and yang were more balanced, one might strengthen these points, perhaps with moxa.

Comment on Conception Vessel 15

The point is also listed as being for the results of excessive sex causing exhaustion in youths, perhaps because it helps to tonify yin and Blood via the 5 Yin, at the same time as regulating them mentally to adopt a steadier approach to life.

I don't know why they single out youths (presumably male?), however. I've had patients of other ages also suffering from exhaustion from excessive sex!
