In reply: The myth we referred to is the commonly held misperception by a significant percentage of the population that natural therapies are inherently safe. As Lewis and Brighthope very correctly point out, the dose ingested by our patient was hugely in excess of any recommended maximum. We believe this is evidence of the misperception, as most patients would not dream of taking 10 or 20 thousand times the maximum dose of “non-natural” remedies, because they recognise that all such remedies have side effects. Our patient’s confidence that he could safely take such a huge dose was, we consider, at least partly a consequence of his belief in the myth that natural therapies are safe.
The fact that the dosage of selenium in nutritional supplements is strictly regulated does not prevent problems such as this — where patients obtain information of variable quality on the Internet, make their own arrangements to obtain the product, and then ingest a toxic amount.
Our article was in no way part of “an underlying agenda to discredit natural products”; it merely highlighted the risks inherent in self-medication based on information of variable quality obtained from the Internet, coupled with the impression that natural therapies are inherently safe. We hope that our call for adverse outcomes of complementary and alternative medicines to be better publicised will go some way to preventing such a tragic error occurring again.
