In Chinese medicine, this point is where the three yin meridians–spleen, liver and kidney–intersect. It is commonly used for urological, pelvic disorders, insomnia, and menstrual cramps.
This point also is used for reproductive disorders (menstrual cycle irregularity, pre-menstrual discomfort, and menstruation pain). So, please be sure not to use it on a pregnant woman for it is also used to induce labor (unless you're quite ready for baby to meet the world!).
Since the point is on the leg, it can be used for pain in the lower leg and ankle.
It is also helpful for digestive problems and pain in lower abdomen and insomnia.
You can find this point on the inside lower leg, four fingers’ width above the ankle bone. Figure the most comfortable way for you to reach the point. You can sit cross-legged and use the thumb of your opposite hand to press on the point. You can sit in a chair and put your leg so that your shin is on the opposite knee and press with the opposite hand. However you do it, be sure your shoulders, arms and legs are relaxed.
Spleen 6 can be a very sensitive point, and may be tender even with just a light touch, especially for women pre- and during menstruation. Just rest your finger on the point, there’s no need to apply pressure. If it’s too tender, release gently.
Some women feel immediate relief from menstrual pain and discomfort when they hold this point. You can start out by holding for 15 to 30 seconds, if that feels comfortable. If you are dealing with a chronic issue, daily holding of this point can be helpful. Hold the point longer every day or so until you work up to one minute. Repeat a couple of times on each leg.
NOTE: If you are pregnant, pressing this point may induce labor so you may not want to use this one.
