Now, I tend to take Hulda Clark with a pinch of salt.
So let me share something else:
"A 70-year-old Japanese woman with gastric cancer in Fukuoka Prefecture, Japan, was found at autopsy to have about 15 adult flukes, Eurytrema pancreaticum, in the dilated pancreatic ducts. (...) This is the second documented case of eurytremiasis in man."

I am looking for more info but for now I am taking pancreatic enzymes and they are very effective, which is interesting considering the above info.
