A passage from Medicinal Plants of the Western Mountain States:

In the late 1800s it was reported that Hoptree contained berberine. This report is suspect since (to my knowledge) the report has not been duplicated. Nevertheless, Hoptree combines well with true berberine–containing herbs such as Oregongrape, Barberry, or Coptis for gastrointestinal microbial complaints (food poisoning).
