Cupping is an accessory technique which has attracted a lot of attention this year as it has been used by such people as Madonna and Gwyneth Paltrow. This technique involves attaching a jar onto the skin by way of a vacuum. This therapy is warming and causes a local increase in the flow of Qi and blood in the meridians. Although jars made of horn and bamboo were used in the past today the material most commonly used in the West is glass.
