I was diagnosed as HEPATITIS B carrier in 2013 with fibrosis of the liver already present. I started on antiviral medications which reduced the viral load initially. After a couple of years the virus became resistant. I started on HEPATITIS B Herbal treatment from ULTIMATE LIFE CLINIC ( in March, 2020. Their treatment totally reversed the virus. I did another blood test after the 6 months long treatment and tested negative to the virus. Amazing treatment! This treatment is a breakthrough for all HBV carriers.
