Re: I personally avoid these SBOs

You may want to consider making water &/or milk kefir. I've had good results with: http://www.kefirlady.com
If you can get your daughter to eat sauerkraut (good luck!) a good recipe can be found at: http://www.healingnaturallybybee.com
I figure if you get your probiotics from food, you can avoid concerns like the ones you're having....& for what it's worth, I think they can combat any other organisms you've ingested....at least that is what studies have shown.
