Today, most acupuncturists use cups made of thick glass or plastic, although bamboo, iron and pottery cups are still used in other countries. Glass cups are the preferred method of delivery, because they do not break as easily as pottery or deteriorate like bamboo, and they allow the acupuncturist to see the skin and evaluate the effects of treatment. 

What does cupping treat?
Cupping is used primarily to treat respiratory conditions such as bronchitis, asthma, and congestion; arthritis; gastrointestinal disorders; and certain types of pain. Some practitioners also use cupping to treat depression and reduce swelling. Fleshy sites on the body, such as the back and stomach (and, to a lesser extent, the arms and legs), are the preferred sites for treatment.
