This does not work at all. Bought it for my oldest daughter and she tried on her own and it didn't work. I then helped her also didn't work. This product is garbage don't spend your hard earned money on this.
As a kid I loved this syrup, obviously I didn't know what was in it. Now as a mom it's rare I buy this for my kids. It's better to make your own, to take comfort in knowing what you put into it. It just doesn't taste that great,
