TCM (Traditional Chinese Medicine) is several thousands of years old. It is said to be mentioned in documents as old as 4000 years. The Yellow Emperor's (2698-2596 B.C. ) internal books are considered to be the first written documentation of TCM. Even today, its effectiveness is the subject of many studies.
Its mechanism is based on the electric properties of the human body, namely the connective tissue's information system and the local systemic hormones, endogenous opioids and neurotransmitters that are released during the therapy, and their effect on the autonomic nervous system and the immune system.
