jobi,
I too was stunned when I read it. Since you were probably using dry leaves, the fluids and such inside the actual leaf were probably all dried up, lessining or removing the toxcicity of them.(?) I'm glad though, you've never had problems. There probably isn't much danger in using them in the enclosures of carniviorous reptiles as the chances for ingestion are so slim, but I suppose the danger is still there. Glad to have been of help.
