Boneset and (potential) liver toxicity

Does anyone here use boneset tea? Buhner recommends it for addressing neurological symptoms (I believe it helps with remyelination), but according to some reports it isn't safe for long-term consumption due to the presence of pyrrolizidine alkaloids.

A 2010 post from Buhner's site claims that these alkaloids are found in related species but not in boneset (eupatorium perfoliatum), but I've read more recent reports that contradict this. I do feel better when I'm drinking boneset tea, but I certainly don't want to destroy my liver.

What's the consensus here?

I used boneset tincture for a year or two—and also boneset tea for a short time. I really don't think it did anything to my liver.
