Yah at first I tried diluting with water the first couple of times, Cuz i figured a drop of peppermint oil in 20 ounces of water wouldnt be that bad. But I guess, I should try diluting it with other oils like it says in that page. I wouldn't know what oils to dilute it with though? --grapeseed oil wouldn't exactly taste good with peppermint and which ones would be the cheapest, and less flavor affecting of the oils?
