Dear Johan: As a medicine student I suggest you should have a good conversation with your phisician before interrupting any treatment. There are lots of herbal treatments that help, but one should be careful in changing drugs for herbs. There are lots of scientific evidences that drives phisician's therapeutics. I hope your son will aways be healthy. Rodolfo --------------------------------- Do you Yahoo!? Yahoo!
