The Ying-Spring points
The Ying-Spring points: the coolers of the meridian system
The Ying-Spring points — the second of the five Shu Antique points on each meridian — lie one step farther from the nails, on the fingers or toes. The character "Ying" refers to a small spring or brook that has just begun to flow — Qi has started moving, but remains close to its origin. Therapeutically, the Ying-Spring points are particularly suited to clearing Heat: they are the coolers of the meridian system.
Location and element
The Ying-Spring points lie on the fingers and toes, just beyond the nails but still on the distal phalanx. On the Yin meridians, the Ying-Spring point is the Fire element; on the Yang meridians, it is the Water element. The Fire points on the Yin meridians are particularly effective for clearing Heat — the Fire element on a Yin meridian has a direct regulating effect on Heat complaints in the corresponding organ.
Clearing Heat and warmth
The primary and most characteristic function of the Ying-Spring points is to clear Heat and warmth from the body. They are the first choice for acute Heat complaints: fever, inflammation, redness, hot flushes and mania — all Yang-Heat patterns that the Ying-Spring points can effectively cool and regulate. In particular, the Fire points on the Yin meridians are especially powerful for this cooling action.
In clinical practice, this is seen in infectious fever, acute inflammation of organs, excessive Heart-Fire with palpitations and agitation, or Liver-Fire with red eyes and headache. The Ying-Spring points of the involved meridians can provide rapid relief in such acute Heat situations.
Disturbances in the Yang meridian pathways
The second application of the Ying-Spring points is for disturbances in the Yang meridian pathways — when the Yang meridian as a trajectory is affected, for example by external pathogenic factors that have entered through the surface. In the six-layer theory of TCM (Shang Han Lun), the Ying-Spring layer corresponds to an early stage of external pathogen invasion in which Heat is the dominant presentation.
Distal treatment
Like the Jing-Well points, the Ying-Spring points also have the ability to treat complaints at the opposite end of the meridian. Through the distal principle, they reach disorders situated far from the point itself but lying along the same meridian pathway. This makes them versatile — not only for local Heat complaints but also for distal applications along the course of the meridian.
