Kidney 4, Dazhong, Great Bell, is the fourth point on the Kidney acupuncture channel. In Chinese medicine it is the Kidney's luo-connecting (or 'junction') point. It supports the Kidney function in a number of ways.
To locate this point you need to know where Kidney 3, Taixi and Kidney 5, Shiquan are located. Kidney 4 lies midway between them but about 0.5 cun posterior ie towards the achilles tendon.
There is an alternative location, 0.5 cun distal to the point described above, which puts the point 0.5 cun posterior to Kidney 5.
As with locating any point, the description of where it is here or in books is a starting point. Palpation alone will locate the point exactly. Sometimes even palpation doesn't solve the problem: only by needling will you discover the exact location.
Direct the needle anteriorly, almost as if towards the tip of the lateral malleolus bone. Up to 0.25 cun.
Local or downwards along the inside of the heel.
Moxibustion: up to 3x.
Strengthens the functions of the Kidney Zang
Steadies the Shen by nourishing the Yin of the Spirit
Nourishes the Heart
By strengthening the Kidney function it assists the Lungs
Specific indications for Kidney 4 as Luo-Connecting point
Because this is the Luo-connecting point of the Kidneys it has an effect not so much on Kidney Yin or Kidney Yang as on the direct relationship between the actions of the Kidneys and of both the Lungs and the Heart.
Lungs and Heart are in the upper 'burning' space, ie the chest.
The Kidneys are in the lower 'burning space', ie below the umbilicus. (In actual fact, their physical location is a bit higher than this, but in Chinese medicine they are perceived as acting in and on the lower abdomen.)
Chinese medicine sees the Kidneys as providing a stable anchor for the Heart and Lungs. (In turn, the Lungs and Heart can lift the Kidneys and provide inspiration and direction in life.)
Taking the Lungs and the Kidney first, when you breathe, the Qi you inhale is directed downwards.
As the 'Qi' is directed downwards, in a healthy person the Kidneys are said to 'grab' or anchor it. When the Kidneys fail to do this, you can't catch your breath, or you find yourself trying to take ever deeper breaths.
This can be quite alarming! This is the situation with asthma sufferers with Kidney deficiency. At one time, this was thought to have contributed to what became known as a 'barrel chest'.
This can also be the situation with coughs and wheezing, shortness of breath from Kidney deficiency.
You may also get this in a lesser form when, perhaps tired, you find yourself sighing or yawning repeatedly. However, sighing from emotional strain is something else, usually described by Qi Stagnation - see my book, below.
A more extreme form of this imbalance between Kidney and Lungs occurs when the Kidney Yin cannot nourish the Lungs properly because the Kidneys cannot send up a fine moisturising spray.
Then you get dryness in the throat and mouth, a dry cough, and sensitivity to dry or hot air. This may eventually lead to Heat in the Lungs, causing coughing up of blood.
NB There are other kinds of asthma, when the Kidneys are not deficient but, for example, the Lungs are said to be 'full or in excess'. Kidney 4 also helps this.
All the luo-connecting points do more than just reach to the related organ, in this case the kidneys. They also affect the emotions.
The emotion associated with the Kidneys is fear.
We are not talking about worry and anxiety here, unless extreme and prolonged. Worry and anxiety tend to affect the Spleen and Stomach first, although as they continue they affect also the Heart and eventually the Kidneys.
Without healthy Kidneys, there is a lack of confidence at the core of the individual. (But read Gallbladder for another aspect of this subject.) The individual quakes at his centre: he is a fearful person. Such a person fears to face the world, hence the desire to 'close the door and stay at home'.
The Kidneys are also strongly associated with the spinal chord and the brain. Indeed, the chord and brain are seen as being an extension of the Kidneys. So when the Kidneys are deficient, there may be mental weakness or nervous system problems.
As age or continued infirmity dissipate the body's resources, its Mingmen depletes, and problems may appear such as
Kidney 4 is often chosen as a main or strongly supporting point for syndromes causing these conditions.

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'.
Published 1986 and, amazingly, still selling. Was apparently used back then by at least one acupuncture college to help students understand Chinese medicine!
Four Reviews so far. (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!
