We do use points located in the Ear but not exclusively. We use points in the ear as an addition to body acupuncture.
It is perhaps more common for us to suggest that the patient has some ear studs fitted as part of the treatment. These ear studs will be left in place for a few days and can easily be removed by the patient at any time.
There are a few varieties and types of ear studs that are available. We prefer to use tiny gold studs which are affixed to the ear with a small round plaster. These are quite discrete and avoid the shiny glare of the gold metal. They do not pierce the ears and have minimum risk of causing an infection.
