Suppose someone has benign tumours and is looking for an alternative treatment.

I known mansked harmala alkaloids have been shown effective in the treatmeant of tumours. But what about rue seeds (either tea or eaten raw)? They contain other alkaloids, which are not harmful (other than for pregnancy) and may be beneficial. Is there any evidence that the seeds would be more effective than mansked alkaloids?

And what would be an effective dosage for daily administration?
