Selection Points by Earth Meridian Ebb-Flowing Rule :Considering the earth meridians is also called considering the earth branches. By this method, a dye (24 hours ) is divided into 12 hour period. Each is represented by a Chinese character called earth branch which, in turn , corresponds with Zany-Fu organ respectively. Then according to different hour periods, the Qi and blood flow ebbs or flows in considering the symptoms at the same time to choose the points to strengthen the mother and reduce the son. In application, when the affected Zang (or Fu ) organ is in excess of Qi-blood flow reduce the son point. When the organs are deficient, strengthen the mother point at the next hour-period when the Qi-blood flow begins to wane. If time for reinforcing or reducing has passed, the excess and deficiency syndromes don't appear obviously, select the Yuan-Primary point of the affected meridian or the affected meridian for treatment. Even reinforcing and reducing can be employed.
