A cotton ball is soaked in alcohol and held by tweezers and lit on fire. It is then placed inside of the glass cup and removed quickly while the cup is placed on the skin. A suction is produced. This is used to move stuck energy by creating a bruise on the tissue. The bruise allows blood to appear and re oxygenate the area. This creates a healing process. This can also be used to eliminate stuck energy and alleviate pain. Cupping is used primarily in diseases such as the common cold and bronchitis.
