AB  - Dietary  supplements,  which  include  substances  known  as  botanical  and  herbal  medications,  are  available  without  prescription  and,  unlike  over-the-counter  medications,  are  considered  to  be  nutritional  supplements  rather  than  drugs.*  These  substances  are  marketed  in  the  United  States  without  FDA  or  other  governmental  premarketing  review  of  efficacy  or  safety,  and  with  little  government  oversight  of  purity,  variations  in  potency,  or  adverse  effects.  Purified  nonherbal  nutritional  supplements  such  as  dehydroepiandrosterone  (DHEA)  and  melatonin  are  also  used  widely  by  the  general  public  in  pursuit  of  “alternative  medicine.”  For  many  herbal  products  and  nutritional  supplements,  evidence  from  controlled  clinical  studies  for  their  medical  effectiveness  is  incomplete  or  nonexistent.  A  summary  of  the  intended  uses  of  some  herbal  products  and  nutritional  supplements  is  presented  in  Table  60–1.
