ah, ok, well I read everything in all those articles because I've been wondering now for a while what these "toxins" are in Syrian Rue. Basically, the article by Dr. Shuglin says that he doesn't know the pharmacological properties of the other alkaloids in rue, nor if they are toxic. So, the jury is out. The other alkaloids may or may not be harmful. So, when in doubt, the usual response is to go on the side of caution.
