There was some research on using Methylene Blue to treat Hep B. I believe it was 70 mg twice a day. I cannot remember the pharma company that did the research. However they were unable to get a patent on it so dropped the human studies. Only downside was that the Methylene Blue causes blue pee.
Methylene blue was used in WWII in high doses to treat infection. Also look for information on the Blue People of Kentucky. Those people were taking several hundred mg a day for years without harm.
