Psoralenoside is primarily utilized in the field of dermatology for its photochemotherapeutic properties. It is often incorporated into treatments for skin conditions such as psoriasis, vitiligo, and eczema. When combined with ultraviolet A (UVA) light therapy, it helps to repigment the skin by stimulating melanocyte activity, making it effective for managing vitiligo. Additionally, its ability to inhibit abnormal skin cell proliferation makes it beneficial in controlling psoriasis symptoms. Beyond dermatological applications, it is also being studied for its potential anti-cancer properties, particularly in enhancing the efficacy of photodynamic therapy. Its role in traditional medicine for treating various ailments further underscores its therapeutic versatility.
