Since following and investing in IPX over the past almost years I've not heard anything about Brilacidin causing liver or enzyme issues.
I believe there may have been some other minor issues during the Polymedix days that were resolved when Menon tweaked the drug.
P.S. If you are or decide to use a Neti pot use distilled water. A woman in Seattle, WA just died from an amoeba that was present in their tap water that attacked her brain. It's rare and there is no known cure. You can Google Seattle Neti Amoeba and find the story.
