You know, I've always wondered what would happen if someone ate the entire jar. Now we knowAt least, hopefully people will be more prudent than I was! GHK's extract was very high quality Mahakea extract. Definately would not have done that if I had used it in a reasonable manner. The tongue thing was because I held probably 1/2-1 level teaspoon in my mouth for like 15-20 minutes. That is my biggest misgiving about extracts; something that can do that (4 day krunk; two of which = fall on your a** krunk) is liable to attract undue attention to kava.
