chinese herbal medicine bath + narrowband ultraviolet b

A combination therapy consisting of a Chinese herbal medicine (CHM) bath and narrowband ultraviolet B (NB-UVB) phototherapy. This regimen is primarily used for the treatment of chronic inflammatory skin diseases such as psoriasis and vitiligo. The CHM component typically involves immersion in a water solution containing extracts from various medicinal herbs with purported anti-inflammatory and immunomodulatory effects. NB-UVB phototherapy uses light at 311–312 nm to target skin lesions, reducing inflammation and modulating immune responses locally in the skin. The combination aims to enhance clinical efficacy compared to either modality alone by leveraging both systemic or local effects of herbal compounds and the targeted action of UV light[1][2][4][5]. Clinical studies suggest that this combined approach may improve disease severity scores (such as PASI for psoriasis), quality of life indices, repigmentation rates in vitiligo, and reduce adverse events compared to monotherapies[1][2][4]. However, evidence quality varies due to heterogeneity in study design and composition of herbal baths.
