Conception Vessel 1, the first point - Ren-1 - on the Conception Vessel acupuncture channel, is where three of the most powerful yin acupuncture channels emerge from the body.

These are the Conception Vessel (this one), the Governing and the Penetrating channels.

This location is between two of the most yin entrance/exit places - the anus and urethra/sexual organs.

It has particular and special qualities but because of its location is not much used.

Other points share some of its qualities, such as Conception Vessel 2 and Kidney 1, so there are rarely overwhelming reasons for using this point.


Location of Conception Vessel 1

On the perineum, on the mid-line, midway between anus and labia or anus and scrotum. In practice, that's very imprecise. They speak of it as being midway between the anus (anterior end) and the labia (posterior end) which is all very well in women.

In men it is said to lie midway between the anus and the scrotum, but where the posterior of the scrotum ends and the perineum begins isn't clear, unless the man is having an erection, when its junction with the perineum is more obvious. (However, many might question whether acupuncture during an erection was appropriate.)

So, failing that, needle it about about half to one inch, or between 1.5 cm to 2.5 cm in front of the anus. Insert vertically to the skin.

Needling Conception Vessel 1

Caution!
If you are of different gender to the patient and there is any possibility of a misunderstanding, however, remote, I advise you to get a chaperone of the same gender as the patient. Indeed, this is good advice whenever using Conception Vessel 1 even if you share the same gender as the patient.

If circumstances preclude the presence of a chaperone or if, even with a chaperone there is any possibility of misunderstanding, and you are still sure that this is the appropriate point for treatment, it may be as well to get written permission signed from the patient before using the point. Get the chaperone to countersign it, if possible.

Depth of Needling

Textbooks suggest half to one cun but in practice about half an inch, unless the patient is drowning, when up to an inch may be used.


(However, if the patient is drowning, do you have his or her permission to use acupuncture, especially at this point? Different cultures deal with this matter in different ways, so be sure you understand the local mores.)

Although I've never needled deeper than that, I've seen a man needled there to a depth of nearly 3 inches (8 centimetres) - and he insisted it was very beneficial, at one time returning weekly for a 'top up' session.

Patient's Position during use of this point
The best way to needle the point is to ask the patient to lie on one side in a foetal position.

If a male patient insists on lying supine, you must ask him to hold his scrotum and penis out of the way while you locate and needle the point.

Needle Sensation at Huiyin

Extends throughout the external sexual organs in men, and the labial and vaginal region for women. For this reason, not everyone wants treatment at this point.

Moxa at Ren-1

Use up to 3 moxa cones. Be aware that this area is more than usually sensitive for many people, that it has many sexual connotations and that heat here can be quite disturbing for some patients.

So before using moxa, explain why you need to use it and what you'll be doing.

Make sure you have their understanding and permission - preferably in writing!

ACTIONS of Conception Vessel 1 - Huiyin - Meeting of Yin

Indications
Because Conception Vessel 1 has a number of different functions, it can be an important and powerful point. I have listed examples of conditions that might arise under each of its actions.

For example, I list headaches under Regulates Yin, but this point can also help headaches due to deficient Yang, although perhaps less effectively than headaches arising from deficient Yin.

  • For yin deficient headaches
  • Cold penis - a condition usually but not always associated with a lack of sexual desire
  • Amenorrhoea and irregular menses
  • Heat in the chest
  • Pain in skin of the body, especially of abdomen and perineum
  • Impotence, infertility and sterility, possibly frigidity
  • Calms the Mind: used for mania but can be used in less extreme conditions


Do please realise that this point is only very seldom the first point to think of when trying to regulate Yin. Many other acupuncture treatments regulate Yin, and lack the sexual connotations connected with Huiyin. Using this point on a whim could, if its use were misconstrued, adversely affect your right to practise acupuncture.

Regulates the genito-urinary area

  • Inability to urinate or defecate
  • Hernia
  • Anal and vaginal problems (see also below)
  • Pain in the urethra, the penis, anus, labia, vulva or vagina

Drains Damp and Damp-Heat

  • Pruritis vulvae - intense itching of the vulvae
  • Swelling in the vulva and vagina
  • Anal itching
  • Constant erections
  • Swollen testes
  • Chronic piles
  • Prostatitis and swelling of the prostate

Resuscitation

  • In coma or after shock
  • After drowning. Some sources say that acupuncture here to a depth of 1 inch (2.5cms) which is more than recommended for normal treatment, will produce urination and defecation if the patient is alive. If otherwise, not.

Regulates Yang

  • Prolapse of anus, vagina or uterus
  • Enuresis (involuntary urination)
  • Involuntary Seminal emissions
  • Sweating of the genitals

Comments on Conception Vessel 1

Conception Vessel 1 - Ren-1 - lies at the lowest point on the body  - the trunk, (excluding the extremities), opposite both

  • Dazhui Governor Vessel 14, a very yang point lying between the seventh cervical vertebra and the first dorsal vertebrae at the top of the dorsal spine, and 
  • Baihui (Governor Vessel 20), at the vertex, the highest point in the body, and therefore (from the point of view of Chinese medicine) also a very yang point.

Apart from conditions of Damp and Damp-heat, and pain, I don't like to drain this point too much, but treatment here does bring energy down from above, hence its use in mania and for promoting urination and defecation.

Its main use is to strengthen Yin which tonifies, if that is the word, yin energy within the body. Yin is nourishing, hence its use in cases of impotence and amenorrhoea.

Being such a dynamic yin-strengthening point, this point strongly supports treatments requiring yin tonification for other reasons, such as in yin deficiency insomnia or anxiety. However, I've never seen it listed for this purpose in combinations of points, almost certainly because those problems can be treated by many other points on the body and the use of this point might be invasive.

Once Again ...

In those countries where personal invasion is treated seriously, the use of this point for resuscitation purposes is probably confined to hospitals and situations where the patient has given prior approval for treatment with acupuncture.


I think even people who understood the benefits of acupuncture might be willing to have acupuncture at almost any other point in an emergency but without prior approval would be very unamused to find this point being used to bring them back to consciousness.

Because of where it is, use of Conception Vessel 1 needs to be carefully explained beforehand and the patient's agreement obtained. A chaperone may be necessary.

When the properties of this point are needed but the patient is unhappy about its use, there are other points that do something similar, such as Conception Vessel 2, just above the pubic bone on the abdomen.
