I was part of an NIH published study at UCSF many years ago. The study is published. I now have a flair of my Lichen Planus of mouth, nails, and other areas. I have been taking 8000 mg total with BioPerine of Tumeric taken with meals three times a day since March. It is a challenge but worth it to help avoid Prednisone systemically. I still require some prednisone topically but hope to avoid the problems of systemic prednisone.
