💬In plain words
What the trial is, and whether it could suit you
The goal of this clinical trial is to learn if a botanical Total Coumarin topical cream (TC Cream) works to treat psoriasis in adults. It will also learn about the safety of the topical TC Cream. The main questions it aims to answer are:
* Does TC Cream improve the psoriasis disease symptoms?
* What medical problems do participants have when applying TC Cream?
* Does TC Cream improve the quality of life of psoriasis patients? Researchers will compare TC Cream to a placebo cream (a look-alike cream that contains no active drug) to see if TC Cream works to treat psoriasis.
Participants will:
* Topically apply the TC Cream or a placebo cream twice daily every day to affected skin for 8 weeks
* Visit the clinic once every 2 weeks for checkups and tests
* Keep a diary of their symptoms and their diseased skin conditions during the application of the topical cream
