Work hypothesis
  To look for magnetite crystals at the acupuncture points seems therefore to be the logical approach.
The aim is no longer to investigate the metallic concentrations allowing orientation in time and space as for the animals. For the human being, the acupuncture point would be a natural source of energy, a sort of battery rechargeable from the outside through the acupuncture needle lodged in the point. The stimulation of the point by the needle would act as if it were charging an accumulator or an electrical condensor. This needle is itself a small energy source, in the sense that it channels the earth magnetic field and the copper thread surrounding the handle can be considered as a Solenoid. The needle is therefore a reception aerial for the surrounding electromagnetic waves. This theory can explain why it sometimes takes weeks between the actual treatment and the recovery.
  The theory about the presence of magnetozomes at the acupuncture point
 

The magnetozomes or magnetite crystals (Fe3O4) represent a system similar to an electrical condensor and/or in a parallel way a metallic coenzyme reserve necessary to any enzymic reaction (for instance: Zn for the insulin). They are naturally present in every individual.

The role of the needle is to stimulate electro-magnetically the “magnetozomes” which are present in great quantities at the acupuncture point. They are repositioned in one direction or its opposite way according to the theories of Toning or Dispersing. Once the needle has been removed, the point gradually releases in due course the energy which has been stored during the acupuncture session.
The heart electrical wave QRST (70/mn) supplies enough energy for the gradual “unloading” of the point to act beneficially on a pathology. A few acupuncture sessions will be therefore often necessary in order to “recharge” the point.
The heart electrical wave QRST becomes an electromagnetic wave : charged in an electromagnetic manner in contact with the “magnetozomes” at the acupuncture level.
  1/ Hypothesis
The QRST wave remaining constant one can assume that the pattern of the transmitted wave will vary according to each acupuncture point and will be unique to each point. The hypothesis could be tested if more samples were to be taken at the acupuncture points, as long as metals varying in quantity or quality are found via a microprobe study (for instance : Fe, Zn, Cu).

Each point will therefore have its own “Spike” or signal, different from the next acupuncture point.
All the acupuncture points along the meridians will be of the Hertzian relay type because of the spreading of the transmitted electromagnetic wave from one point to the next.
The meridians in acupuncture thus remain a virtual entity from a scientific point of view. In this theory, they represent the preferential course taken by the electromagnetic wave transmitted from the acupuncture point under heart control.
For each meridian, the pattern of the wave length which has been sent would be different according to the stimulated point. The stimulation system of the acupuncture points is submitted to a double checking :
. a natural and internal electrical system found in all living creatures : the heart.
. an external system represented by the acupuncture needle and the penetration of the acupuncture point (either by manual stimulation or by the acupuncture stimulators).

Conclusion

1/ The meridian is a virtual entity, which is not tangible nor visible and would be the preferential course of an electromagnetic wave transmitted from the acupuncture point.

2/ Each acupuncture point of a same meridian would act as a Hertzian relay.

3/ Each acupuncture point would transmit from its own spike, its own electromagnetic wave, i.e each point would have an electromagnetic wave pattern, different from the next point.
