Various texts on acupuncture report thirteen different categories of potent acupoints. Among the categories are primary points (sometimes referred to as source points), tonification points, sedation points and alarm points, etc. Hisako Koizumi, MD, of Ohio State University Medical School, who has studied in China and Japan, reports that special emphasis is often given to the primary points.
Dr. Yoshio Nakatani, who developed the Ryodoraku method (1951), used the primary points as test points and would treat with either the tonification point or the sedation point.
My review of five different sources showed some disagreement as to which points were considered the primary point for each meridian. There are also some discrepancies among texts with regard to tonification or sedation points. The points that I work with are the ones that are the mostly agreed upon by various sources. Where there were disagreements I have chosen to utilize the point of greatest agreement or I use more than one point. For example, three texts listed three different points as the primary point for the Kidney meridian (K 3, K 4, & K 5). Since these points are in very close proximity, I utilize them all. Using acupressure, all three points can be easily worked with simultaneously. I also use two points each for the Large Intestine meridian (LI 2 & LI 3) and Kidney meridian (K 1 & K 2) sedation point locations. In a few cases the primary point will also be the same as either the sedation point (B 64, H 7 & P 7—see the examples below) or the tonification point (Lu 9). I found no primary, tonification or sedation points for the Governing or Central Vessels but only for the 12 bilateral meridians.
This collection of potent points may be useful in the practice of acupressure for emotional healing. Rather than using a point at the beginning or end of the meridian or the alarm points to test a meridian, you might consider experimenting with the primary points.
In treating the meridians you might consider an algorithm of primary points, tonification points or sedation points instead of a beginning or end point algorithm. Numerous possibilities present themselves.
Below I have listed examples from the Bladder and Pericardium meridians of the primary, tonification and sedation points.
