i do not understand this stuff at all. there is no real brand on it, yet it is not generic or anything i do not think, especially at like $1.50 a bottle??? plus it is only sold by the individual bottle at this one Grand Union. maybe it is other places but not that i have seen. another, it is kind of lame, too herb-y really. that weird anise / licorice flavor going on but it still does not work well
