Wind-dampness blockage in channels

Wind-dampness blockage in channels (TCM: Feng Shi bi) refers to a pathological pattern where wind and dampness combine to obstruct the flow of Qi (“vital energy”) and Blood in the body’s channels/meridians. This leads to migrating joint pain, numbness, and functional impairment. In modern terms, it often parallels syndromes like arthritis or rheumatism, but is distinguished by its cause (environmental wind/damp invasion, weak constitution) and presentation (pain moves between joints, symptoms worsen in damp/windy settings). Herbal and acupuncture therapies aim to restore flow by “dispelling pathogenic factors” and “unblocking channels.” It is not a molecular entity, drug target, or receptor, but a TCM diagnostic concept.
