My highschool biology teacher once gave us (her class) a tea which made everything taste like dirt. I remember that chocolate candies, spicy hot sauce, and salty crackers all tasted the same after drinking the tea. The effect only lasted a minute or two. It's been a long time, and I can't remember the name of this tea - can anyone identify it?
