I am going to wait for Leslie and the others to chime in as they know more about some of the natural things, but I wouldn't be adverse to trying it at all. No place to get it in the states? I wonder if Trish knows something about it, she's in New Zealand.
How exciting. So do you have some links? Wanna read it too. LOL
