Kraton For Detox

Does anyone know if Kraton capsules work for detox from heroin? Is it ok to buy from overseas? I don't know the legality for Australia.How much does one need to take? What's the deal on buying it online if it's illegal?
It is a tea of some sort right?? Somewhere on this site I have seen folks discussing it. Look back a few months on the heroin and methadone sites.
I don't think it's very safe and can be addictive itself?
