I'll chime in here, as EVERYONE told my husband to try ivermectin and fenbetosal and a bunch of other natural things when he first got diagnosed, he did the "protocol" of some guy online who supposedly cured himself of cancer- but once you dig deeper, you'll see he was still getting treated by a doctor and doing trials, so...
Anyways my husband did it all but after a month or two his liver enzymes were thru the roof! to the point where they called him and said he was in liver failure! He felt fine, wasn't yellow, didn't pee brown etc. but he got scared and quit everything! and it took another 2 months almost for his liver to get back to normal, of course he also got a liver Ultrasound and that turned out fine.
The doctor did NOT know he was on this stuff but knew about other supplements and one thing they said could cause it too is turmeric as a supplement! as a spice it's fine, but it's not supposed to be absorbed into the body and can cause liver damage.
