Unknown – the treatment is part of TCM.
When patients are treated with chemotherapy, they receive drugs regarded by TCM as energetically cold. Cancer is regarded in TCM as the result of too much heat in the body. The stomach, however, reacts to the “cold” with nausea and vomiting. In TCM the nausea and vomiting is due to qi flowing 'backwards' (rebelling). The treatment is aimed at opening the pathways so qi can move in the right direction (downwards). The biological expression facilitating the antiemetic effect seems to be induced by an increase in “slow waves” or “period dominant power” with regard to gastric myoelectric activity and tachyarrhythmia.1-2 These effects seem to be mediated via the opioid pathway,3 but it is not known how the acupoint stimulation induces this opioid signal. The main acupuncture point used is Pericardium 6 (P6); the point is located approximately two inches up from the wrist between the two distinct tendons).
Stimulation of the Neiguan (P6) point relieves chemotherapy-induced nausea and vomiting (NV).
Acupuncture: An acupuncture needle is applied to the Neiguan (P6) point for up to three twenty-minute periods daily during on-going nausea/vomiting. The needle can be stimulated by either heat (moxa) or electric current (electroacupuncture).
Acupressure: The Neiguan (P6) point is stimulated by a wristband with a protruding knob or by finger pressure. The wristband can be worn continually, while the finger pressure is applied as needed, or at least three times a day for 20 minutes.
The treatment can be given by any trained acupuncturist, or by a specially trained doctor, nurse or physiotherapist. Acupressure is suitable for self-treatment.
The exact extent of use is unknown.
In some countries the practice of acupuncture is restricted to health professionals or registered/authorized/licensed acupuncturists.
The cost of an acupuncture treatment session will vary from country to country. A session could typically cost between €30 and €80, depending on whether it is the first or follow-up session. Acupuncture/acupressure treatment for chemotherapy-induced nausea/vomiting is largely given in conjunction with oncological treatment.
