I thought others might want to know that Bob Church isn't the only one concerned about the effects of ephedrine alkaloids, whether synthesized or found naturally in "...Ephedra species of herbs (also known by its traditional Chinese medicine name - ma huang)." http://nccam.nih.gov/health/alerts/ephedra/ In addition to the concerns Bob raises, the spookiest part to me is mixing herbals, which contain variable concentrations/amounts of the active chemical, and ferrets, which weigh about a kilogram. A 10 milligram miscalculation, say, might have little effect in a 70kg human, but could have pronounced effects in an animal as tiny as a ferret. I haven't read all the FML history of this topic, but must ask: why would anyone give amphetamines to a ferret? Rob [Posted in FML issue 3933]
