1. Type of Jars
There are a great variety of jars, but the commonly used clinically varieties are as follows:

1) Bamboo jar: Cut down a section of bamboo 3-7cm in diameter and 8-10cm in length, forming a cylinder shaped as a drum. One end is used as the bottom, and the other as the opening. The rim of the jar is light, economical, easy to make and available in many places.

2) Glass cup: Since the glass cup is transparent, the local congestion at the site for moxibustion can be seen so as to control the treatment.

2. Indications
The cupping method has the function of warming and promoting the free flow of qi and blood in the meridians, dispelling cold dampness, diminishing swellings and pains.

In clinics, the cupping method is mainly used to treat Bi syndrome caused by wind dampness, such as pain of the low back, shoulder, and leg, gastrointestinal disorders such as stomachache, vomiting, and diarrhea, and lung diseases such as cough and asthma.

The cupping method combined with bloodletting is suitable to treat acute sprains accompanied by blood stasis.

The animal horn was used to dispel pus. Along with continual development in clinical practice, the materials for making jars and the methods have been greatly improved. The range of indications has been expanded, since this method is simple and the therapeutic effect is good. This therapy was attracted with great attention and applied in a large scale by the broad masses, and also used as an auxiliary method of acupuncture and moxibustion.
