Ceramic jars are made from clay or porcelain clay and are generally divided into three types: large, medium, and small. The ends of the jar are smaller, and the middle protrudes outward, resembling a bamboo jar. In recent years, doctors in Shaanxi have made spherical ceramic jars, which are modeled after glass jars in appearance.
Ceramic jars are mainly used in fire cupping therapy.
Ceramic jars have good sealing properties, do not leak air, and have strong suction power. The downside is that the jars are bulky and prone to breakage if dropped.
