It is not only safe but it saved my husband from a severe case of candida the doctors could not do anything about. My friend who has had fibromalgia for over 20 years said that she finally got rid of her candida rpoblem thanks to the therapy (she also is eating sprouts and a good diet). She used lots of massages and enemas since she could not drink much therapy (she has to take medication for thyroid gland problem). She got rid of her mercury teeth though before.
