EFT is based on the idea that all negative or unwanted emotions are the result of a disruption in the body’s meridian system. Through tapping on a series of acupuncture points whilst focusing on a specific issue, the EFT protocol allows the meridian system to clear the blockages that are causing the issue, leading to an immediate shift for the client. Research shows that tapping induces a mini-REM state in the brain which helps the brain re-organise the way it stores and processes information. Tapping has also been shown to reduce cortisol levels which helps with stress-regulation and improves heart rate variability.
EFT can be used on a wide range of emotional and physical issues and been proven to be particularly effective with phobias, trauma and anxieties though can be used to shift and process any unwanted emotional state. EFT can be practiced on the client by the therapist and once learnt can also be used by the client on themselves to provide immediate relief when distressed.
Whilst EFT does not replace the client-therapist relationship I have found it to combine exceptionally well with psychosynthesis therapy and believe it could well have been one of the tools Assagioli would have included in the psychosynthesis toolkit had it been discovered within his lifetime.
