I put ten to twenty drops (as per the label says, depending on how bad my problem is) in a glass of juice. I take it once a day, or twice if that doesn't seem to help in a few days. I quit taking it when I don't have a problem anymore, but that's just because I forget. Probably would be better to continue treatment a few days after symptoms go away... but without the symptoms to remind me to take it, I forget to.
