Psoriasis Vulgaris Clinical Trial
Official title:
Efficacy and Safety Comparison Between Refined and Crude Indigo Naturalis Ointment in the Treatment of Psoriatic Vulgaris
To compare the efficacy and safety of refined indigo naturalis ointment with that of crude ointment in treating psoriasis.
Our previous studies have shown that topical application of indigo naturalis significantly
improves psoriatic symptoms. However, patient compliance is hindered because the preparation
is unsightly and stains clothing.
To improve patient compliance, we have developed a refined formulation in which closer to
natural skin tones and less prone to stain clothing. In this study, we evaluated the
efficacy and safety of this refined form of oil extract ointment and compared the results
with those of the original crude form of indigo naturalis ointment in treating psoriasis.
