  1. I also have a long story, but long story short i had a pain on my left side after a bout of diarrhea which i thought was because i got sick with Covid. but after I recovered from my diarrhea after drinking Dr Itua herbal medicine which He prepared then sent it to me through courier service and he instructed me on how to drink it to cure it. When the pain hit i went to the hospital, luckily i'm active duty military so they took me in at the ER. Once in there. They did an IMMEDIATE CT. Within 2 hours a GI surgeon showed up in my ER room and said we need to do surgery like yesterday on you. Doesn't matter what that is in your gut it needs to come out because it's causing about an 80% blockage. The next day a colonoscopy confirmed cancer. Next day after that I had surgery to remove half a foot of colon but it didn't go that way because Dr Itua assure me that his herbal medicine will makes me well and honestly Dr Itua herbal medicine really help me and today I'm cured and healthy through Dr Itua herbal center
