I do think this may be a case similar to the comfrey study done with baby rats, but on the other hand, we are always learning new data as time and technology advances. That being said, Michael Moore in his book, Medicinal Plants of the Desert and Canyon West states that chapparal is a good liver tonic that goes well with milk thistle and puncture vine. However, when I looked up contraindications of chapparal online, several articles popped up, warning of liver toxicity, and warnings to avoid it, especially in children, people with liver conditions, and people taking medication.
I thought the disparity in the two sources were worth a discussion here.
