Treating steroid-dependent psoriasis from the blood-heat syndrome perspective: A case report

This case documents clinical improvement following TCM intervention in steroid-dependent psoriasis. Important limitations include the single-case design, lack of control group, retrospectively estimated psoriasis area and severity index/body surface area scores, and self-reported long-term outcomes. The observed temporal association between intervention and improvement may reflect natural disease variation, placebo effects, or other confounding factors. While this preliminary observation merits further investigation through rigorous prospective studies, the current evidence level remains limited and cautions against causal interpretation.
