★★★★☆
In reading your post on psoriasis, I thought to mention a product that I have been using.
Although it treats my psoriasis within 6-8 weeks, new spots appear in different areas of my body. Ugh!
The product, which I purchase on Amazon is called Qicaogangmn Caoben Yijun Rugan.
It is a cream. You can look into the ingredients and perhaps find it useful in coming up with your own concoction??
I had my former dermatologist who is Asian look at the ingredients to make certain there were no steriods in it. He concluded there were not.
Good luck
