Background
In TCM, shī rè describes the simultaneous presence of dampness (heaviness, stickiness, sluggishness) and heat (redness, burning, yellow discharges). It is the pattern of "muggy tropical weather, but inside the body" — a feeling of being simultaneously weighed down and inflamed, often showing up as yellow, sticky, or malodorous discharges and a general sense of "something hot and wet is stuck." Longdan Xiegan Wan targets damp-heat in the liver and gallbladder channel — the "heat" manifests as irritability and bitter taste, the "damp" as genital discharge or lower-body heaviness. Bazheng Pian targets damp-heat in the bladder — the "heat" shows as burning urination, the "damp" as urgency and frequency. Same tag, different anatomical terrain.
