There are multiple pericardium-6 acupuncture points that you can use for disc placement.
Acupuncture points are anatomically defined areas on the skin relative to certain landmarks on the body. Traditional Chinese medicine explains acupuncture as a technique for balancing the flow of energy or life force — known as chi — believed to flow through pathways (meridians) in your body. By inserting needles into specific points along these meridians, acupuncture practitioners believe that your energy flow will re-balance.
In contrast, many Western practitioners view acupuncture points as places to stimulate nerves, muscles, and connective tissue. Some believe that this stimulation boosts your body's natural painkillers.
There are multiple acupuncture points for each of the 12 meridians (or pathways) in the body. If you would like to try an alternative pericardium-6 acupuncture point that you can utilize for biosignal processing disc placement, you can place the disc on the left shoulder blade or the underside of the left foot.
