The technique known as Fire Cupping, Body Vacuuming, or Cupping was an ancient Chinese healing practice. The ancient way was to create a vacuum inside a cup made of horn, bamboo, glass, or metal, by burning a combustible (like moxa, or alcohol) inside it, then quickly applying the cup to the skin, allowing the force of the vacuum to draw up the underlying tissue. The body surface extends into the cup, and there is usually a reddening of the area under pressure. Sometimes massage oils or aromatherapy essences were also used. Applied to significant acupuncture points, cupping was respected as a way to stimulate the flow of Chi, similarly to massage, and acupressure.
THE ACTION OF SUCTION CUPS
Suction Cups produce vacuums on the body's surface by manually withdrawing the air through the suction gun, rather than the traditional way of burning up oxygen. If you think of massage in terms of positive pressure (pressing in on body tissues), then you can think of Massage Suction Cupping as a negative pressure, drawing body tissues outward from the body, to stimulate them with a reverse massage.
The skin is pressed up against the magnetic "needles" or points, when they are used. These are supplied in the "Biomagnetic" sets.
