A partial vacuum is created in glass cups and these are placed on the body. The cups are left in place or moved over the skin. Where the cups are move, oils will be massaged into the skin. Cupping has a number of effects that help in localised healing. It draws stagnation and toxins closer to the surface, increasing blood supply to the area so the small blood and lymph vessels can carry away debris and bring in nutrients. The vacuum also helps to separate muscle fibres that may be twisted or bound, making it possible for muscles, tendons and ligaments to glide smoothly, easing movement and decreasing pain.
