Origin and Background

The concept of dampness in TCM is rooted in the ancient belief that the body is subject to the influence of six external factors, one of which is dampness. Dampness is characterized by a sticky, heavy, and cold nature and can lead to various health issues when it accumulates in the body. Banxia Decoction was first recorded in the Shang Han Za Bing Lun, an influential medical text compiled by Zhang Zhongjing in the 3rd century AD. Since then, it has been widely used and modified to suit various dampness-related conditions.
