Denis Stewart is a herbalist from the Hunter Valley (NSW, Australia). He is an associate professor at University of Newcastle since 2002. He founded the Southern Cross Herbal School in the late 1970s.
He presents a weekly radio show on 2NUR FM, a Newcastle-based radio station, on health topics.
I am concerned about some of his material. I posted Denis a (real) letter and sent an email without receiving a response. I also sent an email to 2NUR FM listing some concerns.
Below is a list of some of the concerns that have not been addressed.
