  3. My name is Layla, I tested positive to HEPATITIS B December last year when I had severe ribs pain and swollen stomach, I was told it has no cure at the hospital, but the doctor gave me some drugs to slow down the viral load and it became worse after some time. Out of frustration, I went online for more info about the ailment and cure, and luckily I found a comment about Iyabiye’s herbal treatment and how he has cured people with it. I contacted him and I tested negative to the virus after I completed the treatment.You too can be free. Contact:+234-815-857-7300 (iyabiyehealinghome@gmail.com)
