Alopecia areata （AA） is a common hair loss disorder， and the core pathogenesis is the internal gene-ration of turbid toxin caused by

qi

movement disorder in the liver， spleen， and kidney. Turbid toxin serves as both a pivotal etiological trigger and a pathological driver of disease exacerbation. Clinically， AA can be classified into four principal patterns， including liver constraint with spleen deficiency， internal accumulation of damp-heat， liver-kidney depletion， and

qi

-blood depletion. Therapeutic strategies prioritize clearing and resolving turbid toxin while regulating the

qi

movement of the liver， spleen， and kidney. Accordingly， different formulas were applied. Self-formulated
