Cupping is the use of glass cups on the skin to improve blood circulation to the area. A flame is used to create a slight vacuum in the cups, then the cup is placed on the skin.  Cupping helps loosen up tight muscles as well as hasten the process of healing by increasing blood flow to the area.  Also cupping is used on the upper back for conditions such as common cold, coughs and flu to draw out any infection in the body.
