i'm not sure, but some pharmaceutical diuretics are dangerous in resoect that they wash out potassium from the body....i don't think dandellion does that, but not sure...might wanna check..
BFA, if it helps, I'm looking at my Dandelion root bottle right now. 2 capsules have 1.03g and the directions say to take 2 caps 3 caps per day. Now, is 3g crossing the line? I don't think so, that's prob a safe number to cover their asses from getting sued. I'd venture to say 4-5g but I don't know, maybe more, possibly 3g should be the limit
