Well I will just venture a guess as to a MH response to this question, did you read any past of MH posts?
At most, a 3 day orange juice fast is recommended with metal in the mouth, as past 3 days you will leach metal from the mouth. No cilantro until metal is removed, as it is a chealtor of Hg. I suggest that you read and search more prior to more self experimention, to avoid major health problems.
