Commentary

The kidney meridian is connected to the Bladder, it’s main functions are to store essence and to dominate the reproductive system. also it gives essence to the water metabolic system and reception of Qi. There are 27 needle points in this meridian from Yong Quan to Shu fu. The kidney meridian is a yin organ and its element is water so it’s energy flow is in an upwards direction. This point is used for healing headaches, blurring vision, sore throat, dryness of the tongue, loss of voice, dysuria, infantile convulsion, the sensation of fever, sensations of pain in the sole and loss of consciousness. The location of Yun Chuan is on the sole of the foot in the depression in the plantar flexion, approximately at the junction of the anterior third and the posterior two thirds of the sole between the second and third metatarsal bones.

Some believe that Yong Quan is in the center of the foot, but that’s not so. Yun Chuan point is very rarely seen on any martial arts charts. I have only found it on one chart myself. Some say the reason is that it was to hard to strike. I found that the technique used to strike Yun Chuan had been lost to time and its masters did not let the techniques go out of the province of China. Whatever the reason may be there are very few masters who use it and it is even more rare to find a master who might teach it.

But when I think about it, Yun Chuan point is very easy to use. The first time I tried to use Yun Chuan in a kermite was w hen my opponent tried a front kick. I stepped out to the side (of course he tried to reach me anyways) and I scoop blocked the kick and hit Yun Chuan with a one knuckle fist (firmly but lightly) as I stretched his leg out. It should be done in one flowing motion. The first result was the opponent losing control of his other leg and lost balance. After that he complained of an ill feeling in the leg. It was also a little disorientating later in his body as well so he couldn’t continue for a time. This strike was not a direct hit as the strike hit the center of the foot. The true target is a quarter inch higher. Later I found it quit easy to apply the strike to other types of kicking techniques as well. It can virtually be used with almost any kick. It also may be applied with a toe (type) kick, but it would be dangerous to do so. I have unveiled this point because there is no explanation anywhere that I know of.

Yun Chuan can be combined with other pressure points as well. Almost any pressure point after K#1 is hit. But a secondary strike to the heart, peri or triple warmer meridians will exacerbate the damage. A singular strike to K #1, will for the most part, stop the attacker from continuing the attack causing him to be unable to stand any longer. Yan Chuan may be activated with pressure as well. Pressing a thumb into the point will cause the victim to retract his leg quickly, so it may be use to repel a leg lock.

Yun Chuan is an excellent revival point to bring back someone who has been out ( k.o.) too long.
Use it when all else fails. Rubbing in a circular motion ( clock wise) on both feet. This point can also be used in the practice of QI Gung for general health, rubbing each sole fifty time per day. This exercise will balance the water-fire elements in the body.

Yun Chuan can become deadly if hit correctly or (if you wish) incorrectly. Being the first point of the Kidney meridian and being a grounding point to the earth can disrupt earth energy Qi. For this reason, mental imbalance is a first sign of more disturbing problems to come and may possible lead to death. If you see these signs seek Acupuncture. There is no cure for these problems in western medicine.
