never heard of it... linky?
is it anything like that yakult stuff? (the same noise you make when drinking the stuff)
My other half had to drink that **** snd similar stuff for about a year after she had a really bad bought of food poisoning, which turned into infective collietus- camylabacta (sp?) which landed her in hospital with a 'blistered gut' as the consultant put it. The antibiotics they gave her killed off all the bacteria in her stomach/gut, including the ones that are supposed to be there... not a happy bunny
Back on topic, never heard of what you're talking about here in the UK... dunno.
