Dear friend
I used the ndf on my 7 year old child who has mercury poisoning for
2 months starting with one drop 2 times a day up to 6 drops 2 times
a day each day increase of 1 drop and continued on the 6 drop twice
a day for a bit over 2 months, no sffect whatsoever, if you need any
more details I will do what I can to help.
