I got this recipe several years ago when someone was telling me what to drink to "clean out" my system. I now tend to use it when I'm sick, hoping it will "clean out" the germs. Sprout really enjoyed drinking it (luke warm of course).
1/2 lemon should be enough for a standard coffee cup. When using a travel mug, I normally use a whole one. Add the honey and brown sugar to taste. (Yes, I like things sweet!)
