"She showed me research on mistletoe. I saw other patients through her who seemed to be thriving," said Diaz, who also researched the topic. "It sounds like it's very common in Europe, but hasn't hit the mainstream in the U.S."
The mistletoe trial's three phases will take between five to eight years and involve patients with different kinds of cancers and ultimately cost in the millions. Diaz expects that once the trial begins, it will attract other funding. Weleda Group, the Swiss manufacturer of Iscador, is providing the extract free for the trial.
"At the end, if we improve outcomes, if mistletoe becomes one of the ingredients in that cocktail, we'll be pleased," Diaz said.
