I just say that acupuncture is the manipulation of the electromagnetic field's flow through the human body. Getting a treatment is merely unblocking the rivers of energy flow. The earth emits an electromagnetic field. The people that discovered how the channels worked lived by nature. They woke up when the sun rose, and went to sleep when the sun set. The only reason why the channels are mapped the way they are is because they all came up with the same routes through trial and error. However the problem with herbal medicine is that our TCM materia medicas only have the qi movement resulting from plants native to east asia.
The schuman resonance effect, the electromagetic field, and gravity all play a part in how acupuncture works. The biggest conflict most of us come across is if the universe does the work after the needles go in, or does the pracitioncer transmit his/her own energy to the patient.
Then again is the energetic field that is being played with our very own energies? souls? we know it leaves the human body at death. Numerous glows above DU-20 have been witnessed from bedside at hosiptals.
